A person’s “power plants” earned the year 1645

Polaris solar PV net news: according to the State administration of taxation recently issued a notice, effective as of July 1 this year, national grid company buy distributed solar power projects and power products, invoices issued ordinary from it rather than its own power, which is good news for Kong Qingbin. On March 28 last year, Kong Qingbin complete household PV on-grid, as “Anhui sells the first person”. A year later, Kong Qingbin “sell” what business?

Benefits: year power 1820 degrees earned 1645

Yesterday afternoon, this reporter went to Kong Qingbin housing compound roof. 7 panels are fixed to the top edge facing South direction, collected the maximum sunlight. Kong Qingbin, told reporters that the equipment generating capacity over the past year for 1820. “This is a reference value, PV is mainly look at the Sun. “Kong Qingbin said, when weather is sunny, there had been day power peak of 9.8 degrees may run into fog and wet weather, and sometimes can only send one or two units a day.

According to Kong Qingbin statistics, 1820-40% (728) for home use, the remaining 60% (1092) was sold to the State, specific proceeds mainly into three pieces, including their own electricity savings in electricity, State subsidies, after proceeds from electricity sales.

“State subsidies 0.42 Yuan per unit sold was 0.436 Yuan at one time, that is to say by 0.856 Yuan per unit is sold to the State, earning 934.8. “Kong Qingbin said their savings in electricity, according to market price, 0.556 dollars per unit, combined with State subsidies, 0.42 Yuan per unit, a total of 710.5 savings, two plus total receipts in 1645.

Difficulty: subsidy is relatively small, some procedures are still cumbersome

A couple of days, and Kong Qingbin subsidized day, subsidies are generally issued on a quarterly basis by the power companies, Kong Qingbin began to worry about get, but later found the worry is unnecessary.

After the State administration of taxation recently issued a new notice, Kong Qingbin cost will decrease. “Before taxes 3 points were less than 20,000 yuan, and after July, this section simply eliminated. “Kong Qingbin said, the State encourages the obvious, but was a little less. “From the present cost recovery had nearly a decade of time. ”

There are some obstacles, Kong Qingbin view, awaiting a breakthrough, such as examination and approval procedures cumbersome problem, assign problems such as how public roofs, “is still the most important issues in the sense that, on the one hand many people not enough awareness about photovoltaic, people’s awareness of environmental protection on the other hand can’t keep up. ”

Next: yielding about 15% will expand the scale of power

This year PV data through observation, Kong Qingbin end of something, then he prepared his 1.75 kW PV system capacity expansion to 10-kilowatt. For the “home power plant”, 10-kilowatt is a high capacity, beyond this value, general household cable cannot afford and will need to be replaced.

“Always wanted to expand, but not a normalized data, and no one had done before, not to rush into action. “Kong Qingbin going step by step, in power between March 28, 2013 to March 28, 2014 after carefully observing the situation, he eventually concluded that the domestic photovoltaic power generation yields of around 15%.

“15% yields were already high, and the market has barely begun. “Kong Qingbin confident for the future, stated that it would have been done.

Cost: how much money set of power generation equipment to be installed?

“One watt cost almost 10 dollars, 1.75 kW more than 17,000 yuan. “Said Kong Qingbin, differentiated models of various equipment, the quality and price are not the same, but on the current market situation, according to front line quality built, cost 8 yuan per watt, looking for a professional company to install it may 20% more design and installation costs, and cost up to 10 dollars per watt.

“Because it is the initial stage, many companies are less willing to live like this. “Kong Qingbin now rely on their own experience, has more free advice from Hefei city, more than 20 photovoltaic installations, as well as other cities and counties of the province, some commercial and residential installation, but Kong Qingbin, photovoltaic power generation speed and scale of development is far from enough.

Civil servants and will take the lead in “power generation”

Hefei will introduce further measures to promote PV industry development

In Hefei, individuals like Kong Qingbin “power generation” more and more people. With the development of photovoltaic industry, preparation in public service in government agencies in the city of Hefei, take the lead in promoting photovoltaic power generation. Hefei in the future or it will become “first town of Chinese photovoltaic applications.”

Situation is still in the early stages

Recently, this reporter learned from the Hefei city Committee through a letter, currently PV power station installed capacity reached 140MW in Hefei. Hefei city, Han Dong, Director of software and electronic information Committee through a letter, told reporters that according to their calculations, 1W power investment 8~10 Yuan, coupled with government subsidies, families in general installation of photovoltaic equipment, really need 10 years or so cost recovery, “but solar is 25, followed by 15 represents the profitability of domestic photovoltaic power stations. ”

According to reports, the photovoltaic plant in Hefei city is divided into three categories: home power station, colleges and scientific institutions, industrial plants power station power station. “Personal household power station, built 22 homes in the city, there have been 105 users in rural areas”, the New York Philharmonic said, overall, the Hefei “power generation” start is still at the exploratory stage.

Future creating “PV power application” the first city

On speed up the PV application from June 2013 at the opinions on promoting the development of photovoltaic industry and on speeding up this year by the notice on the application of PV, in late June, on further standardizing and speeding up the city, Hefei photovoltaic applications implementing rules will be formally released. This very intensive policy published in national PV promotion is also rare.

It is learnt that in Hefei city’s blueprint for photovoltaic power generation by 2015, solar building integrated solar thermal project built in Hefei city with more than 200, installation of various types of solar photovoltaic street lighting, landscape of more than 10000 units, photovoltaic power station installed capacity reached more than 500MW, photovoltaic industry output value of over 30 billion yuan, “Hefei photovoltaic power generation at that time will be ranked in the forefront. “Han Dong’s introduction.

Issues: subsidy is not attractive enough

It is reported that currently use personal PV in Hefei, will have government subsidies, according to the capacity of a one-time 2/Watt subsidy, is relatively low.

On this, Han Dong to reporter revealed, Hefei is brewing improve subsidies, “this year July yihou built grid of PV station, can considered by capacity gives of one-time subsidies standard by 2 Yuan/w improve to 3 Yuan/w; on rural residents applications construction of family PV station, in city financial 3 Yuan/w subsidies of based Shang, County city financial again according to 1 Yuan/w of standard supporting. The original 10-year cost recovery period can be shortened to 6 or 7 years. “However, the New York Philharmonic also said that standards finalized these subsidies still need time.

Approval procedure approximately 15

It is understood that ordinary members of the public to apply for individual PV, need to conduct feasibility study, property permits, for the record, completing the application, development of programmes, projects and other processes for approval. Under calculated by reporters briefly, if you want to go through the full process takes about 15 steps.

Han Dong, photovoltaic power generation, after all, involves the power grid project, from a security point of view, go through a rigorous examination and approval is inevitable, “mainly in order to avoid security risks. But so far the various units for personal applications for photovoltaic power generation is still very much support, as long as the public right to a roof, the approval is not difficult. ”

Residents ‘ environmental awareness is weak

It is reported that the photovoltaic promotion speed is not fast in the city, public awareness of environmental protection is an important reason to keep up. Han Dong, prepared in Hefei city will be photovoltaic power generation combined with the low-carbon life, enhance the use of new sources of information, especially prepared at the city’s public service in government agencies, first of all promote individual photovoltaic power generation.

It is understood that the Hefei city, released on June 25, was “to promote PV industry initiative”, hopes that public servants would come home roof resources lead in installed photovoltaic power plant, to produce a good role model.

Yin Jianping: solar thermal power generation built into the life of the dreamer

Polaris solar PV net news: Sun Bao, Chairman of new energy in Jiangsu–interview with Yin Jianping

Solar thermal power generation industry in China after years of ups and downs, what force to sustain the industry matured? Who is quietly extends the industry’s roots which grow into towering trees are gradually have power? We cannot ignore these people, these forces, in the silence of this industry for several years, they kept a dream, never change.

Seven years ago, in 2007, Academician Wang Zhijiang was invited to speak at that time of Jiangsu Polytechnic University gave a lecture on solar thermal power generation, and now, seven years later, grew up in Changzhou, Jiangsu Province, China’s first with completely independent intellectual property rights and the integration of solar thermal power generation for heat storage technology company.

This was founded by Yin Jianping Sun Bao Xin, Jiangsu power Ltd (hereinafter “Sun Bao”), in today’s Yin Jianping, it was seven years before this opportunity, so he threw himself into the solar-thermal power generation this industry has great potential, but hopefully this will get in his way, “destiny” year of entrepreneurship most legendary passages.

Opportunities

In 2007, 46 year old Yin Jianping has 23 years of business experience. Wanda reducer factory in Changzhou, created in 1984 and will be brought to the steady development track, 1998 focused on emerging market for solar water heaters to create Sun Bao and evolved into an industry leader in 2007 when an even bigger when the opportunity comes, Yin Jianping chose to return outing.

For any enterprise, is behind their choice to enter an emerging industry opportunity also means significant risks and challenges. “We have a wealth of experience in high-precision manufacturing, solar water heater, a relatively low technological content and lower requirements for manufacturing industry cannot give full play to our advantages, so we want to start looking for new opportunities in other industries. “Yin Jianping told reporters of his original grounds of new business development.

Lecture Wang Zhijiang Yin Jianping of the audience listening to them passionately, he then began to light up to three years of sustained attention to thermal power generation. At the time, to Spain as the representative of the international solar thermal power generation markets are bracing for a second outbreak, Spain introduced a high FIT incentives for solar-thermal power, accelerated development of the market. While domestic thermal power to light involved only at the research stage, few understand the industry.

Meanwhile, the solar water heater market in those years began to show explosive growth potential, Sun Bao-relying on water heater market sales income for later entered the capital Foundation for solar-thermal power generation market. By 2010, Yin Jianping was keenly aware of the general trend of solar water heater market is set to decline and began to accelerate into solar thermal power generation sector.

Select

Solar-thermal power complex, involve large segments of, what I should do? Yin Jianping gave her three options: tube, brackets and storage system, he ultimately chose the storage system. “Whether collector or a stent, is relatively simple to manufacture such products, rather than integrated systems, from what we’ve done similar to the reducer and solar water heaters, and once the market is getting better, is soon expected to be a fierce competition, which we have discovered before. While the storage system is the core of integration capabilities, this soft power as soon as others is very difficult to reproduce, it is easy to form enterprise’s core competitiveness. “Yin Jianping said.

Although simply Po at the manufacturing capacity of the Sun, Sun Bao-collecting tube or stent products easier, but focus on the long-term development of the enterprise, also based on Yin Jianping’s previous marketing experience, Yin Jianping resolutely chose solar-thermal power generation core technology is a largest storage system as a starting point. “We are going to do the most professional of photo-thermal heat storage solutions. “Yin Jianping believes that today has been able to prove that he had made the right choice.

The fact is do like so, Yin Jianping predictions several years ago has not started in the market today have been verified, current domestic thermal power collector manufacturers have more than more than 10, manufacturers also detected through the DLR there are three or four, the competition is very fierce. In terms of the integrated storage system capabilities, in addition to Sun Bao, China Guangdong Nuclear solar energy, Center has major input in this area, few other companies involved. And this one especially Sun Bao to go farther.

Because of this, engage in research and development of heat storage technology is difficult, but also require huge capital investment. “When we first started doing the exactly how much money is needed to get into no end of, I also consulted several industry experts. Several experts at the Chinese Academy of Sciences I would suggest saying, ‘ estimates this to carry out the technique successfully you need 200 million commitment, this should not be to you a private enterprise, should be the State to pay for them to do. Too risky. ‘ “Yin Jianping recalled.

But this hasn’t Yin Jianping, because it gave him more confidence, “I always thought of China’s private enterprises are able to do something, private enterprises in controlling costs can clearly do better than scientific research units. We have to fight for every penny is spent wisely, they are standing in the standpoint of scientific research institutes to 200 million, probably in my heart I was thinking the next, I may need 20% would suffice. 40 million is affordable to me. ”

Results far exceeded the Yin Jianping initial psychological expectation, “up to now, our funds invested in thermal energy storage project has nearly 70 million, so far has reached the expected objectives. Although greatly exceeded earlier expectations, but basically I was within acceptable limits. “Yin Jianping said.

Also need to be pointed out is that whether China Guangdong nuclear was in control, their overall group capabilities are far stronger than the Sun treasure, Sun Bao as a less overall strength of private enterprises, put into research and development of heat storage system will undoubtedly need greater courage.

Building the dream

Must admit is that thermal energy storage system integration are related to thermodynamics, chemical, mechanical, control and other disciplines integrated technologies, which had previously engaged in lower-level solar water heater manufacture of Sun Bao, the difficulty is so huge.

Yin Jianping had a clear understanding. “Our advantage is in the machinery and equipment manufacturing has a wealth of experience in the field, for thermal energy storage tank, chemical salts, and other related equipment, we easily can be designed and manufactured according to specific needs. And for the chemical industry and other fields, we through targeted recruiting certain professionals to make up in terms of talent, we can say that regardless of cost. ”

Yin Jianping believes he can do more reasons to heat storage system because he’s confident of their ability to learn new things. “In 1995 I have acquired a silk mill, it is no exaggeration to say that, within six months I went from a layman to be half of silk reeling expert, I even solved a lot of silk reeling factories over the years have failed to resolve a number of issues, some upgrades and innovative improvements. “Yin Jianping tried such an example to support his learning ability.

Learning ability based on a person’s view of things, Yin Jianping, based more on his focus and persistence of the thermal energy storage technologies. Yin Jianping said, “when you put this thing into your life when, what for you is not hard. ”

Yin Jianping said, was doing. In order to master the design of thermal storage system technologies, read foreign literature around his team, read the related technical information can be filled half a room of 20 square meters of offices. He personally went overseas many times the solar thermal power plant study, prior to his departure that he will do his homework carefully enough to see which parts and to ensure that each field trip has the actual harvest.

In 2011, Sun Bao-demonstration projects started to plan the construction of a storage system, with master in practice is a full-service technology. After a year of preparation, in June 2012, the demonstration project was officially started construction, to October 2013. This project from design, manufacture, construction and commissioning were completed independently by Sun Bao. Sun Bao, tank made of steel structures, piping, piping design, thermal insulation, warm up, heat, anti-clotting treatment, integrated control and other aspects to overcome many difficulties. In November 2013, of molten salt system started working, after more than half a month, molten salt melts through the system, temperature up to 400 degrees Celsius, after 3 months of debugging and run more than once, fully meet the design criteria. In March 2014, molten salt temperature to raise up to 550 degrees, and after more than 20 days of operation, the entire system is running stable, the indicator properly, the project ran successfully.

“Equipment manufacturing is our area of expertise, such as salt, molten salt heat exchangers, although we all do for I don’t know how many times the design improvements, but basically the difficulties encountered can be resolved smoothly. The whole system down, we believe that the pipeline of scientific and rational design is the core of thermal storage system design, we found hundreds of times on improvements. “Yin Jianping said.

This 20MWh storage system total more than 30 million, realized the localization and completely independent intellectual property rights, Sun Bao has the design integration storage system for commercial solar-thermal power station capacity. Sun Bao-an important milestone in the development of the company, while Yin Jianping, this is “doing a great business,” root of dreams!

Sun Bao wujin jiaze is located in the old area of town, the reporter saw this storage system, independent research and development of control system for the system to achieve a full, individual monitoring points have clearly shown on the temperature display. Simulation trough the storage system at the same time conducting oil heat and molten salt heat storage, and Tower both direct heat of molten salt technology solutions. Yin Jianping told reporters at the project site, “we need to do is secure and economical storage system. Safety is the first priority, thermal storage systems must ensure that the safe operation of its lifetime in 30, this premise as much as possible to reduce costs. ”

Yin Jianping believed that “operation experience is without a doubt a commercial power station thermal storage systems development, the most valuable asset. Sun Bao of the successful operation of the storage system and long-term operation, will provide our team built up a wealth of operational experience, after this we will lay a good foundation to undertake thermal energy storage projects. ”

Yin Jianping’s dream is relying on this 3 years and spent more than 30 million heavily built thermal storage system began to take root. “Sun Bao’s future ability to become a fully integrated storage system manufacturers. Solar thermal power generation market is heading into its game-changers, smart grid energy storage market is now poised, Sun Bao’s development potential and space will be very large. “Yin Jianping has begun to sketch Sun Bao’s future in mind,” is expected by the end of this year, Sun Bao will be listed for the new ban, leveraging the capital market to help businesses move forward faster and better development. ”

50 and know of heaven, Yin Jianping for this year is more than 50, comes as the fate of Yin Jianping chose life for the third time of the year again when the opportunity comes entrepreneurship, but this time, venture’s purpose is not to make money, Yin Jianping dreamed of starting a really great company, but this time, his selection has given him enough space to realize such a dream!

Polaris solar PV net news: market review

180 million cake cut: “PV entrance” help battling losses?

Earlier, the National Energy Board raised to 14GW PV new capacity this year, distributed to 8GW 6GW of terrestrial photovoltaic power station. Calculated in accordance with 1GW needs investment of about 10 billion dollars, focusing on distributed involving 80 billion yuan.

2014 World Cup games, “China’s Yingli, PV household” alternate characters appear in the game, this is Yingli Green energy holding company limited to sponsorship type advertisements. But couldn’t cover the awkward reality behind sponsorship of the scenery, the world’s largest PV module shipments of business losses for three consecutive years. “Solar PV homes” PV enterprises truly reverse the situation can become a new outlet? For Chinese inhabitants, towards “zero-tariff era” on the road, how much will encounter difficulties?

2. distributed PV will be part of the project or the new deal and enjoy a 1 Yuan/kWh feed-in tariff

By “power” returns far below the “spontaneous personal use” income, “spontaneous personal use” part of the electricity production, electricity revenue is not guaranteed (operator not available), seeking financial support, has been the most vexing questions distributed PV projects.

However, recently circulated in the industry of an upcoming new deal, might be able to correct the situation.

It was stated that the new plan would “less than 35,000-volt grid electricity is less than 20,000-kilowatt, and effective utilization of tidal flat, barren hills and wastelands, agricultural greenhouses, ponds and PV projects” included in the distributed category and locally ground station re power subsidy price.

5. solar policy revision: 20MW agricultural greenhouses and fisheries subsidies light complementary projects or by ground station

Some media have reported, distributed PV policy will likely change. Existing rumors include: first, countries will increase the quota of surface plant, thus reducing the quota distributed (ground and distributed 6G and 8G tiles, respectively). Secondly, the low voltage grid-connected up to 35,000 volts, 20 MW in the following agricultural greenhouses and Yue Kwong complementary items may be included in the project scope to distributed power station, according to ground station price execution, and therefore distributed utility projects 8G w goals or accomplishing. There are claims that likely the country will adjust the electricity price subsidies distributed, from 0.42/kWh for 0.5 Yuan per kWh or more.

1. Shanghai PV industry status and development cause of lag

From the entire solar PV industry chain, the PV industry development in Shanghai lagged behind the nation’s major areas of PV industry development. Polycrystalline silicon ingot manufacturers, Shanghai is almost blank manufacturers, Crystal, Comtec, sporadic and only nine manufacturers, the insufficient capacity of 200MW (only 1% per cent of national output); the production of photovoltaic cells, National Chiao Tung University after the Sun was sold, and only super solar days and Shanghai.

Visible on the PV industry in terms of manufacturing, or applications, in terms of production capacity, production, fixed asset investment or profit, revenue and other indicators, the PV industry development of Shanghai are lagging behind, and this China’s largest industrial city of Shanghai’s economic position risked. After analysis, I believe that PV industry in Shanghai has several factors in falling behind:

Internal and external environment has decided we need a non-renewable fossil fuels “alternative revolution” must be implemented vigorously “develop” and “use” renewable and clean energy strategies. If the “energy revolution” to restore the PV industry’s “new strategic industries” position, fundamentally reverse the PV industry in a wrong way, straighten out the relationships in the PV industry, believes China’s clean energy strategy will step onto a new stage. That would defuse the enormous constraints to sustainable economic development bottlenecks, no doubt to the Internet and the third industrial revolution is characterized by new energy waves enter the ranks of the developed countries.

3. the personal application of distributed PV needs to consider three key factors

PV modules are installed on the roof, will convert solar energy into electricity, the roof will power, which is distributed solar power. Even though individual applications for distributed PV on-grid does not need any qualifications, but apart from policy, you have to take into account some objective factors, first we must take into account the objective conditions of residence.

In theory, all residents can apply for distributed solar power, but in fact requirements of distributed PV on the roof area is still quite high.

Compared with the widely built large photovoltaic power plant in the desert, rooftop solar building integrated photovoltaics and solar power plants will make it feel more directly into green energy from PV.

According to estimates, a residential building, laying on the roof solar panel, realization of building integrated photovoltaics, spontaneous 40 degrees. If this House is to buy 100 kilowatt-hours of electricity from the grid, you can now buy 60 kilowatt-hours of electricity. Just think, if the promotion of distributed generation in the country, means that the power supply will be reduced by 40%, equates to a saving of 28% coal-fired electricity, also can reduce the thermal power plants of 30%, this contribution to the world will be enormous.

Professor Sun Yun, Nankai University reminder: SI: environmental issues cannot be ignored

Polaris solar PV net news: consistently in many countries of the world in recent years in the field of photovoltaic research and development strength, low cost, large areas of CIGS (Copper-Indium-Gallium-selenium) battery can already see results. Although its market share is less than 10% of total PV market, but with the CIGS technology breakthrough and the improvement of technology maturity, which will break the single crystalline silicon PV market battery monopoly, with its excellent price-performance ratio becomes a non-homogeneous high-end products will occupy an increasingly large share of the market.

Professor Sun Yun, Nankai University

Reporters: Professor Sun, Hello! Existing pollution in the production process of crystalline silicon cells which link? The current situation? If a technology and equipment are effectively addressed?

Sun Yun: I think the major pollution in silicon and wafer production this aspect, because made of quartz sand of silicon process, requires carbon to produce carbon deoxidation, made of Silicon of purity of more than 97%, relying on its purity 99.7%~99.9% acid pickling. Whether it is chlorine to produce Silicon tetrachloride, Silicon is handled by hydrochloric acid to produce trichlorosilane, goes through distillation, purification, then condensed by hydrogen reduction of high purity polysilicon raw material. Much of this process is carried out at high temperatures. Silicon single crystal ingots or pull in the vacuum condition, higher than the melting point of Silicon 1410 degrees Celsius after a certain amount of time to complete. So the wafer manufacturing process, carbon dioxide emissions, chemical waste disposal, leakage of chlorine-containing gases or liquids, will have varying levels of pollution on the environment. In addition, in silicon chip proliferation of pn junction in more than 900 degrees, so the whole process of amorphous silicon solar cell with high energy consumption, bringing large quantities of greenhouse gas emissions, have to arouse people’s attention, especially the yield, the greater, more important issues. United States gang o and affiliated to the Department of energy national laboratory, Northwestern University research team found that install solar modules made in China and shipped to Europe, its carbon footprint will be in Europe twice for the local manufacture and installation times. Mainly refers to the Chinese standards of environmental protection and the effectiveness of the plant requires less refining and production of amorphous silicon solar cell process requires large amounts of energy, and China used in this process energy is used more fossil fuel than their European counterparts, and low energy efficiency. So the normally high pollution and high energy consumption is above both.

Reporter: amorphous silicon solar cell production collective pollution is still there? Is the industry’s problems, or the problems of enterprises themselves?

Sun Yun: in addition to outside the Silicon raw materials, I think crystal silicon solar cell production and not the entire industry chain has contaminated, such as packaging production almost pollution free, diffusion process of acid and alkali process of cleaning and etching etching, Groove will use some pH stuff, before release, to be dealt with, but also to have greater input than the thin film solar cell to prevent. Thin film solar module cleaning glass or other substrates, and don’t need to acid etch, use small amounts of organic cleaning agent, not only there is no pollution of acid-base and vacuum coating, PV and solar module manufacturing and finished in a workshop, so thin-film battery in this context basically there was no pollution.

I think the pollution of amorphous silicon solar cell industry chain, except for carbon emissions, in order to present technology makes the production process cause pollution are problems of enterprises themselves, mainly to see the alignment is not complete supporting facilities, if implemented fully, coupled with strict management, even though production costs higher, but pollution problems can be avoided.

Reporter: are you as a leader, your specialty is the study of CIGS thin-film batteries. In your opinion, the technology direction for pollution problems?

Sun Yun: so far, we haven’t found CIGS has serious pollution problems. CIGS films by selenization technique after, generally use highly toxic gases hydrogen selenide (H2Se), exhaust gas treatment device, eventually discharge should not be a problem. In addition, most of the CIGS cells, there is a transition layer of cadmium sulfide (CdS) of about 50 nm from the wet process (CBD), its waste liquid which contains small amounts of cadmium (Cd), and after treatment can reach the national standard after discharge. CIGS cell content of Cd in cadmium telluride (CdTe) falls far short of the battery and CdTe cells containing Cd layer around 5~7 μm. CdTe and CdS both of these films are very stable to simulate fire degrees Celsius on the volatile case found no cadmium, solar module packaged well and do not cause pollution. If there is a pollution problem, Germany and the United States would not allow production. At present, overseas have CIGS batteries using cadmium-free transition process, such as Japan of CIGS SolarFrontier battery, no Cd the element, this also reflects the Cd can be removed from the CIGS cells, which is an important direction of the product.

Reporter: CIGS manufacturer in China’s current battery products containing the Cd which ingredients?

Sun Yun: at present, the CIGS production manufacturers such as Hina, place des Vosges and other products containing Cd, no Cd in the country has not seen reports. Because of relatively high conversion efficiency CIGS products containing Cd, higher conversion efficiencies than no Cd 1%-2%. In addition, the CIGS solar module of Cd element in minimal, not as serious as imagined. Especially if manufacturers the ability to damage and failure of solar modules are responsible for recovery of concentrate, people had no need to worry about, of course, to be able to provide the community with no Cd batteries.

Reporter: with amorphous silicon solar cell (module), what are the main advantages of the CIGS thin film solar cell? What are the advantages of better marketing?

Sun Yun: from the battery itself, the advantage is more than the first, low cost and secondly, manufacture process of low energy consumption; and, third, high conversion efficiency of four, good low light response, output power higher than the crystalline silicon solar batteries last, to make a flexible battery with high power density, has a broader application.

We say from a scientific point of view, is the low cost, the current high cost is due to the industrialization of battery technology is still in the incubation period. This product is a cheap glass, stainless steel foil deposited on polyimide substrates or polymer films for solar cells, a few films together around 3~4 μm, very little precious raw material consumption. Crystalline silicon solar cells you will need 200 microns, only this thickness can absorb sunlight and clean. Otherwise, it will be partially absorbed by, affect its efficiency. Silicon ingot slices, zigzag down the Silica fume can no longer be recycled, because it contains a lot of metal components not easily regenerate purification. Each piece you want to cut 300 microns from silicon ingots, the equivalent of one-third Silicon raw material depletion.

Crystalline silicon solar cells from silicon to the commercialization of solar modules, is done by the socialization of industry chain, implementation of specialized mass production, the current product sales price has been reduced to the extreme, profits were assessed by industry chain enterprises. CIGS cells completed within the whole industry chain in a small workshop, and basic raw materials into the plant processed of glass, it’s solar module directly to the PV power plant, each process can be adjusted in the workshop, reducing logistics costs, and component cost control and profit margins are greater.

Low energy consumption in the CIGS solar module production process, too high a temperature will cause the glass to bear. For preparation of light on a polymer substrate of flexible CIGS PV module can only be done at 450 ° c temperature below a short time. Crystalline silicon solar cells from silicon to module, its energy consumption is much higher than thin-film batteries.

SI module conversion efficiency of the laboratory world record world record in 20.5%,CIGS cell conversion efficiency for a long time, the last two years continuously refreshed by enterprises or research institutions, has now reached 21% (Germany Solibro-Hina created). Production line of glass CIGS solar module production efficiency had reached 13%~14%, while mainstream silicon solar module efficiency for PV market 15%~16%, average efficiency of monocrystalline silicon solar module for 16%~17%, judging from the CIGS developments, average efficiencies than amorphous silicon solar cell production line components will be just around the corner.

Due to CIGS thin-film optical absorption coefficients is now the highest of any photovoltaic material, its spectral response for solar cells is also very wide, 1000nm wavelengths still have high quantum efficiency. Test results have shown that in the same place, the same power of PV power plant, energy output than amorphous silicon solar cell 10%. The power station installed at same power prices, the same power plant the benefits of additional 10% and steady decline, indicating that its optical performance and value is outstanding.

I feel, market application aspects, CIGS battery while has low cost, and high conversion efficiency, and anti-radiation capacity strong, and stable not recession, traits, application in distributed station has is good to market competitiveness potential; due to its appearance tones soft elegant, and weak light response good, also very for Yu high-end buildings of BIPV glass curtain wall; on the, stainless steel foil or poly n Asia amine lining late of flexible battery, not only retained has glass lining late battery of excellent performance, and weight light, and can curling folding, and fear fell touch And more suitable for portable mobile power station cut into different size components as required, apply more flexible. Can be embedded in a tent on the roof can also be folded to carry, feel free to open in place for notebook computers, printers, and mobile communication devices; can also be embedded in clothing, in the Sun to charge portable electronic devices. Polyimide substrate CIGS cells, its power to weight ratio up to 1500W/Kg (unpackaged), are unmatched by all current solar cells. In addition to stainless steel foil with CIGS cells have the same application, but also has excellent performance, and is the first choice for some spacecraft. Therefore, the flexible CIGS cells whether they are military or civilian has broad prospects and huge market demand.

Reporter: in your mind CIGS thin-film battery technology improved in the future and how much, there is no technology roadmap?

Sun Yun: CIGS solar cell current laboratory technology matured, major scientific questions to confirm, but require further and finer. The core technology of large area solar module industry has broken, can produce high performance battery pack. Mainly focuses on how to reduce costs in the future, so its price acceptable to the market. I think industrialization is still flawed, copy the expansion has not been reached on the technical level, in Western countries, is unlikely to open such high-end technology to China. Bottleneck lies in the equipment, how to ensure the uniformity of the film (requires multiple uniformity of structure and physical properties of compound semiconductor materials), product yield, stable online monitoring, process control, and reducing the fault rate of the equipment and machine downtime. In particular the manufacture of CIGS thin-film devices is core, but a sample is the subject matter of the technology and equipment has not yet fully mature, you also need to constantly optimize and upgrade. Only the line to copy the expansion shows that CIGS battery technology has achieved real maturity, then FirstSolar CIGS cells will appear. If all the homemade 300 MW output, module average conversion efficiency of 13%, yield is 90%, its battery can cost less than $ 0.5 per peak watt, up GW level production of amorphous silicon solar cell cost.

Reporter: what do you think of CIGS thin film solar cells and amorphous silicon solar cell application?

Sun Yun: amorphous silicon solar cell prices low, high conversion efficiency, monopoly of the photovoltaic market at present, mainly used in various forms of photovoltaic power plants, have an advantage in a large power plant construction on the ground. CIGS cell products there are three forms, namely glass module, stainless steel substrate, flexible solar panel, flexible polyimide substrate modules, each must have a more suitable applications. The flexible battery for conventional crystalline silicon solar batteries cannot be achieved now, is a diversified variety of photovoltaic cells, can play a special role in the field of traditional PV may not cover, can have independent pricing system that does not compete with amorphous silicon solar cell, as people’s awareness of product and applications continues to expand its potential market demand is growing.

Rigid CIGS modules of a glass substrate, with crystalline silicon solar batteries suitable for various forms of photovoltaic power stations. From the appearance of tone and low light-generating capacity, for glass curtain wall with a more prominent advantages, its industrial technologies are currently defective, needs to be perfect expansion to reduce costs. Once the technology is mature expansion, CIGS cells with crystalline silicon solar battery flat, will have a very strong market competitiveness. However, the CIGS module capacity even at hundreds of gigawatts, will not replace crystalline silicon solar photovoltaic market main body of rare precious metal Indium restricts the battery after all infinite, then there may be another Earth-rich raw material manufacture of cheap, efficient batteries replace all battery, become the subject of energy.

At present, the domestic production of amorphous silicon solar cell decay rate the issue has been quite prominent, because of mass production, the blind pursuit of low-cost, so that product quality as before, I suppose next PV market will go there because of the recession and other quality problems caused by a series of disputes, when the time comes people will find CIGS cells stable performance and low decline rates and other advantages, will get more popular.

Dragon photoelectric fall mystery

Polaris solar PV net news: in the fundamentals of the industry downturn, 2012 is a foregone conclusion in cases, Feng’s family seems to have chosen the bigger losses quarter of 2012, to transfer a portion of the profits to the first quarter of 2013, trying to signal the reversal of the market performance of the company, while’s annual report in 2012 and 2013, while first-quarter released on April 25, 2013. In this way, its use of good first-quarter performance gradually reducing to 12 million shares

As a Solar Silicon material production, one of the leading enterprises in the field of processing equipment, raise 909 million Yuan IPO Dragon photoelectric (toast by the market on December 25, 2009, listed the day’s closing price of 26.99 dollars, later share price rose all the way to 38.49 dollars. However, with the photovoltaic industry to go downwards, the company’s share price continued to decline, its controlling shareholder, in trouble, the company was the media repeatedly questioned the violation.

End of the first quarter of this year, Feng Clan Dragon photoelectric stake drop to about 50 million shares, per cent of total equity of 25.3% and almost in a State pledge. Since March 3, 2014, TL-electro-optical stock has been delisted, announced to Noah Technology Ltd and Feng Jinsheng, Changzhou, said controlling shareholders equity transfer issues are still being negotiated, seems to be winding up of plans out of business. Once prosperous feng’s family is how we got to this point of it?

Deep pledge dilemma

Dragon optical’s listing, photovoltaic industry is in strong support of the national policy when the rapid growth of a King, benefiting from the sharp expansion in the middle and lower reaches of the enterprise and its spending spree on the upstream purchase orders, Dragon photoelectric continue to increase investment in projects to expand production capacity. In order to raise money, Feng clan since 2010 continues to pledge its shares held Dragon photoelectric, for associated businesses (huasheng fine ceramics technology in Jiangsu Province, Changzhou mosun solar materials limited), large customers (Jiangxi xuyang Reddy high-tech company limited) or Sky Dragon photoelectric guarantee their loan.

In September 2011, Noah technology and Shandong International Trust Co, signed the assembled funds trust, Lu Xin-Heng Xin 3rd TL-electro-optical stock right pledge contracts of shares, 12.5 million shares of its stock Dragon photoelectric (6.25%) for its loan pledge. The trust’s total issued amount of 100 million Yuan, for a period of 18 months, cordon and stop lines respectively fell to project investment amounts to pledge the stock market with a total value of 1.5 times and 1.4 times times. In other words, once the Dragon photoelectric shares fell to below 12 dollars, Noah technology is required to pay a deposit or additional shares of credit collateral, and as soon as prices fell to 11.2 Yuan, Noah had to fulfil its share buy-back obligations in advance of science and technology, or trust company may exercise the right to liquidate the pledged shares. As of October 11, 2011, Noah Dragon photoelectric science and technology has pledged days 57.6 million shares, 94.13% per cent of its stake in the company, accounting for 28.8% of the total share capital of the company.

With Noah technology is similar to Feng Jinsheng on February 16, 2012, 15.2 million shares of the company in trust-Shandong hengxin 3rd collection in trust program 14, was pledged. The trust has collected 83.2 million Yuan, the term for 18 months, cordon and stop lines similar conditions and previous trust contract, you can calculate the cordon to 8.21 Yuan, while the stop line at 7.66 Yuan. Feng Jinsheng fall into the plight of pledge, coupled with the pledge of shares, Feng Jinsheng had pledged Dragon photoelectric 25.21 million shares it held in the 25.2 million shares.

Happens is that the photovoltaic industry just started going cold from the second half of 2011. In 2012, under the impact of shrinking demand and overcapacity, increased competition in the industry, resulting in photovoltaic products continued to fall, sales plummeted. TL-entire industries are built around of photoelectric photovoltaic industry layout, so the impact is huge, price all the way down. On March 30, 2012, the company’s share price dropped below Noah technology trust pledge 11.2 exit line, starting in mid-July this year’s share price dropped below 7.66 Yuan Feng Jinsheng mortgage exit lines.

Chairman holdings difficult rescues

In days Dragon photoelectric shares below Noah technology of pledge stops line, and no reverse signs of situation Xia, company bulletin said, Chairman Feng Jin was born in April 27, 2012 to 10.08 Yuan of ASP holdings has 300,000 unit days Dragon photoelectric stock, accounted for total equity of 0.15%; while commitment Yu future 3 months within in shares below 12 Yuan/unit of conditions Xia continues to holdings 100,000-1.7 million unit, accounted for has issued shares of 0.05%-0.85%. It is easy to see, Feng’s family hope that the share price will go back to Noah’s mortgage equity line of science and technology.

At that time, the market information is a positive reaction, TL-electro-optical stock from April 27, 2012, the minimum price of 9.6 Yuan rose to its highest price of 10.66 Yuan on May 8, bounced around 10%, but then return to the downtrend, it is difficult to return. Indeed, Feng Jinsheng 9.11-9.54 Yuan on May 28, 2012 only increased the price of 217,000 shares, increase total equity amounted to 0.1084%, well below the 0.85% cap on holdings, is not additional holdings as the shares fell further after the number. Thus, Feng Jinsheng’s holdings are not optimistic about the company’s future, but to stimulate shares rose, trying to relieve the pressure of Feng’s family trust stops, its second increase is to a large extent in order to meet the commitment announcement before.

Delayed lifting stocks as falling

As of December 25, 2012 Dragon photoelectric listed for less than three years, technology and restricted stock held by Feng Jinsheng Noah on December 27 of that year to lift sales. Because of Feng’s trust pledge for the family needs a lot of money to fill the holes and are expected once the ban expires, companies will face heavy selling.

What’s interesting is, fiduciary pledge 7.66 Yuan after being below the stop line, Feng Jinsheng on September 27, 2012, additional commitments, within 6 months after the first limited without reduction, its shares to extend the locking period on June 25, 2013, trying to slow the market worries about upcoming divestments. In fact, he was almost their entire stock in the pledge, nor to reduce. Round the announcement caused the company’s share price rebounded. However, Dragon optical in 2012 when the three quarterly reports revealed that thanks to the photovoltaic industry downturn, has formed a larger loss in the third quarter before it expects 2012 loss of 1.15-130 million yuan in net profit.

Shares hold, until December 4, 2012 reach its nadir 5.21 Yuan. In hindsight, Feng Jinsheng Tianlong electro-optical stock, on February 16, 2012 pledge of 15.2 million shares in 2013, 7 August, Shandong provincial international trust company limited through the transfer of Justice and explains Feng Jinsheng was no other assets to fill the hole in the pledge can only be expected to rebound in stock prices for their salvation.

Fill the reduction of actuarial debt

Bifengjinsheng lucky, Noah technology is a certain maneuver. On January 10, 2013 Noah bulletin reduction plan of science and technology, plans in the next 6 months, a fall of no more than 16 million shares (8%) TL-electro-optical stock.

Noah technologies on July 13, 2011, pledged to the 4 million shares of Shanghai Pudong Development Bank Zhengzhou branch TL-electro-optical stock, on February 5, 2013, rescinding the hypothecation. Noah technology day to the low price of 5.72 Yuan per share aggregate reduction of block trading platform, 22.88 million Yuan.

Based on this funding, Noah technology prior to April 26, 2013 (a day after the quarterly disclosure) previously pledged to the 6 million shares of Shandong provincial international trust, TL-electro-optical stock about rescinding the hypothecation, to 5.51 Yuan on May 3, the price of sale, 33.06 million Fund. Subsequently, on May 6 from the Shandong international trust and lifted the pledged 6 million shares, and the price of 5.72 Yuan on May 9 all sold. Noah technology by reduction with 90.26 million Yuan altogether these three funds, used to fill Lu Xin-Heng Xin 3rd trust equity debt.

The drop process, giving the market a good key performance expectations, in order to avoid reduction of the expected impact on the share price. In the fundamentals of the industry downturn, 2012 is a foregone conclusion in cases, Feng’s family seems to have chosen the bigger losses quarter of 2012, to transfer a portion of the profits to the first quarter of 2013, trying to signal the reversal of the market performance of the company. Dragon photoelectric 2012 seasons has reported only 5 million yuan of business revenue, coupled with asset impairment losses of up to 325 million dollars, while a loss of 426 million Yuan, and brought the year’s loss of 511 million Yuan, much larger than three quarterly losses disclosed by the expected value. And by the year 2013, a quarter, the company’s operating revenue reached 114 million dollars, only a slight loss of 10.6 million dollars, operating conditions improved significantly.

TL-electro-optical reduction of large shareholders in order to successfully, well-designed financial statement disclosure will’s annual report in 2012 and 2013, while first-quarter released on April 25, 2013. In this way, von’s family used a quarterly achievement plus a succession of reduction of 12 million shares.

Bend over backwards avoiding losing shell

Noah technologies funded by a share reduction trust debt, Dragon photoelectric began planning how to profit in 2013, so as to avoid being delisted alert special treatment. Although the company has transferred a portion of the profits from the end of 2012, but photovoltaic industry fundamentals have not significantly improved. In addition, ST Suri’s potential debt default may also lead to massive bad debts incurred by TL-electro-optical, the company still faces the risk of losses.

At this point, the method is ‘ strong profitability of assets through asset restructuring, at the end of the newly acquired assets can be included in the consolidated financial statements, improving the profitability of listed companies. On June 3, 2013, sky Dragon photoelectric material asset reorganization of business planning, major programmes are of Dalian City link existing shareholders additional shares acquired 100% of its shares. However shortly after June 26, Dragon photoelectric resumption announce restructuring plan failed, reason: certain conditions have not been ripe, does not meet the time completing a major reorganization of the standards specified in the regulations.

Another method is to try to increase revenue, reduce costs, enable companies to avoid loss. On November 1, 2013, sky Dragon photoelectric announced a partnership with Shanghai chaori signed a two-year cooperation agreement on production and operation. Under the agreement, the Shanghai chaori provide 770 million dollars worth of plant, equipment, Dragon photoelectric in Shanghai chaori Payables to the company to reduce its 33.12 million Yuan/year depreciation expense. This can minimize the Super day for up to 115 million dollars in receivables provision for doubtful accounts 3–4 million dollars. November 22, 2013 Dragon photoelectric bulletin, co-production with the Shanghai chaori Convention rights entrusted Feng Jinsheng’s son Feng constant power controlled affiliates. Under the agreement, constant power will pay a management fee to the 36 million yuan per year, two-year totals of 72 million Yuan. In this way, companies do not have to set aside hefty bad debts, it can also increase revenue.

Thus, according to announcements published on November 5, 2013, forecasting 50.01 billion yuan net profit in 2013, 2013 annual results have improved customer situation of the photovoltaic industry has gradually improved since the second half of, the company increased inventory, and through a variety of channels receivable to dispose of part of idle assets. Notice also pointed out that the non-recurring profit and loss effects on the net profit amount is expected to be approximately 6-7 million Yuan, mainly for the company’s land transfer revenue and Government subsidies. While the first three quarters of the company’s total non-recurring profit and loss is 20.93 million Yuan, means that companies in the four quarters will be 40 million or 50 million of non-recurring profit and loss. Affected by this impact, TL-opto-electronic equities trading on the day. Technology stocks stage rally came as Noah, and again on December 6, 2013 at 9 per cent of the price reduction of 3 million shares.

Auditors meet resistance no turning back

Dragon photoelectric 2013 results letters were disclosed on February 28, 2014, is expected to achieve revenues of 337 million dollars, rose 91.6% to achieve 6 million yuan in net profit attributable to shareholders of listed companies, rose by 101.2%. This November 5, 2013 issued in advance of their results were consistent. Dragon optical’s closing stock price on that day to 9.92 Yuan. Surprising is that express comes just a week after the disclosure of performance on March 7, Dragon photoelectric announcements intended to dismiss Lixin accounting firm showed that Ericsson does not agree to issue an auditor’s report the company thought.

Dragon photoelectric to pay 700,000 Yuan hsing Hua certified public accountants for the 2013 should be employed instead of auditing firms, but also did not cooperate with the long days of zhongxinghua taking up optical wheel. Dragon optical performance bulletins were released on April 22 and 25th, respectively, revision notes and 2013 annual report in 2013, only 221 million yuan of business revenue, a loss of 130 million yuan in net profit, leading Dragon photoelectric became the first two consecutive years of losses, being delisted alert specifically to handle the growth enterprise market.

So far, the company’s controlling shareholder, also appears to be turning back without surgery, only “just walk away”. (The author, Associate Professor of accounting and Finance Department of Shanghai Jiaotong University)

Different options for installed solar thermal power station technology

Polaris solar PV net news: for different size of solar thermal power generation project, which technology is best for projects have already installed? LuxResearch published a report this issue triggered heated debate.

Different technical route most suitable for the installed capacity of solar thermal power plants designed for how much has always been controversial, leading research and consulting company LuxResearch had published a report entitled “TurningUptheHeatonAdvancedConcentratingSolarComponents” solar-thermal power generation research report considered, Tower and Fresnel technologies most suitable for developing large and small projects, respectively.

LuxResearch and even by 2020, air cycle solar thermal power tower technology and supercritical carbon dioxide cycle LCOE of Tower-type solar thermal power generation technology will lower than polycrystalline silicon photovoltaic 31%~33%.

LuxResearch says, “Fresnel solar-thermal power generation technology is most suitable for small projects and development of technology. With molten salt as the heat transfer fluid the LCOE of Fresnel technologies 6% lower than the polycrystalline silicon photovoltaic, which has the largest potential market leading small solar-thermal power generation project development and ISCC combined cycle power generation project, assisted by industrial heat use, oil mining, water treatment and other substitution effects in the field. ”

Fresnel solar-thermal power generation technology leader in enterprise global sales Vice President of Areva solar JayeshGoyal thinks, that Fresnel technology cannot be gained in the field of large-scale solar thermal power generation project development competitive views are wrong.

Small projects

JayeshGoyal says, our goal is to develop the large Fresnel solar thermal power station installed capacity up to 250MWe and 17 hours of thermal energy storage system you want to configure. “Said Fresnel technology is best for small solar-thermal power generation project development is right on the one hand, since Fresnel collector system is modular, high performance-cost ratio. But it is not suitable for large solar thermal power generation project development, this is something we cannot agree with. “JayeshGoyal said.

Goyal also referred to in the above-mentioned report, Fresnel technologies will be able to compete with polysilicon solar in LCOE terms expressed doubts, he considers configuration except in the Fresnel molten salt heat storage, photovoltaic batteries storage scenarios to measure both the LCOE is possible.

“LCOE predictions, I’m trying to say is, if contrast adjustable power (energy storage system configuration) the LCOE, Fresnel solar-thermal power generation technology will no doubt win for photovoltaic power generation. But for no energy storage project, and for any kind of solar-thermal power generation technology to beat on LCOE photovoltaic power generation requires a considerable period of time. “Goyal said, he also said,” I light the future development of thermal power generation at present do not yet see a clear road map. ”

Fresnel technology backers say the technology and lower cost compared to other CSP technologies, primarily because of their relative trough technology uses light cheap flat mirrors, Tower technology tracking and control system is relatively simple.

Reflective film trough solar systems SkyFuel’s Chief Commercial Officer KellyBeninga are keen to stress the most mature, the most widely used the superiority of the trough solar thermal power generation technology, he thought-trough technologies in solar-thermal power projects of all sizes are a good choice.

As a trough technology developer, SkyFuel behind trough technology beyond reproach. Beninga said, SkyFuel has tried in the past to develop the Fresnel system. “We build a Fresnel system prototype proves the low optical efficiency of Fresnel CPV system unable to offset the low cost advantage of simple structure. “SkyFuel argues that its practice is proof of that.

Operating efficiency

“The lower optical efficiency of Fresnel system requirements you have to build a large enough field, this increase will be higher than the cost of system structure of simple cost-cutting. “Beninga said,” SkyFuel contrast research findings have won European support for independent research, we do not say this because we are developing now trough technology. We make a choice early on the two systems, but after comparative tests, we selected trough technology. ”

He is referred to in the above-mentioned report “in the large-scale development of solar-thermal power station, Tower technology trough technology more cost than you will in the future economic benefits” conclusions are excepted.

Tower technology is currently proven opinion will gradually surpass trough technology in the future, because it can achieve higher operating temperatures, high temperatures can lead to higher system efficiency, lower power costs. Installed more solar thermal power station project, Tower technology is more cost-effective.

But Beninga won’t agree with this, he believed that based on some assumptions to get to a conclusion that is chock full of, in particular, the tower technology supporters claim that technology has a higher operating temperature than the slot just is in molten salts medium Tower power station and taking the power station of thermal oil as the medium contrast.

In many solar thermal power station that is now running such comparison may be appropriate. But trough technology has gradually developed, many of the trough solar thermal power project developer is also planning to develop with molten salt for new refrigerant plant, this can also be achieved operating temperatures above 500 degrees Celsius.

Meanwhile, he also pointed out that the tower technology LCOE is currently not beyond-tank technology, Tower technology supporters argued that with the maturity of the technology, cost is bound to hit trough technology is only a hypothetical did not become reality.

Sand heat storage solar-thermal power generation of thermal energy storage technologies optional path?

Polaris solar PV NET: U.A.E. Masdar Institute of technology (MasdarInstitute) and the United States solar energy holding company (USSolarHoldings) and some other units are currently in advancing the research and development of a new thermal storage technologies, the sand is extremely common as a solar-thermal power generation for heat transfer and heat storage media, whether the technology has the potential to become solar-thermal power generation efficiency and low cost of thermal energy storage system for future road?

SANDSTOCK project

In September 2013, the Masdar Institute of technology in a research project team began a new thermal energy storage project, called SANDSTOCK, the goal is to develop a sustainable, low-cost computers for automatic loading and unloading through the gravity of solar heat and heat storage system, which uses sand particles as heat transfer medium of the collector and the heat storage medium.

Masdar Institute of thermal energy storage project leader NicolasCalvet said in his published an article, “sand there are some excellent properties, it was cheap, and can be used under high temperature of 1000 degrees Celsius, while the temperature of the molten salt only at 600 degrees Celsius. Higher temperatures could lead to more hot steam, resulting in higher power generation efficiency. ”

This design concept was inspired by the old timer hourglass. Its system constructed and common of double tank melt salt storage hot similar, main by cold tank and hot tank composition, cold tank placed above, hot tank placed below, cold tank of temperature about maintained in 250 degrees Celsius around, sand in not inflow hot tank zhiqian in cold tank in the storage, cold tank used class hollow cylindrical body of design, overall section similar Yu a built-in hollow round Taiwan of cylindrical body. Between the hot tank and cold cans set up a different Cone, hollow and round table of cold cans connected through a valve and the bottom of the table at the bottom, forming hourglass-like shape.

Map: Masdar Institute of design

After the cold tank valve is opened, the sand flows from the cold tank, below the junction into hot jars, junction also was concentrating solar rays focus of sand in the joints is quickly heated, stored in a hot pot, then release the heat as needed. Hot pot embedded in a heat exchanger, water through the heater produces superheated steam, evaporator and superheater, drives a steam turbine to generate electricity. High temperature sand releases the energy use of mechanical conveying device and returning it to the cold tank, waiting to enter the next cycle. To realize closed loop sustainable process.

But to make this storage system the application needed to reflective concentrator System II. As shown in the image above, reflector of sunlight reflected by the secondary reflector gathered to the sand flows through the junction heating them. U.A.E. Masdar was completed in January 2010 based on secondary reflection Tower is the world’s first solar-thermal power generation demonstration projects, installed capacity of 100kWth. By Masdar Institute of technology and the project Japan Tokyo Institute of technology jointly designed and consists of Japan, Mitsui shipbuilding Corporation completed the construction.

Dr NicolasCalvet said, “we want to develop a new sustainable technologies, rich local materials for thermal storage can be used as an alternative to Chile imports thousands of tons of molten salt, sand is the U.A.E. ‘s one of the most common reserves of low-cost materials, is also very stable at high temperatures of 800 degrees Celsius. “Calvet said, to do the research, you first need to select the most suitable sand. We need in the U.A.E. ‘s major deserts and coastal areas to find different kinds of sand, thermal characteristics of sand, through the use of advanced microscopes to determine the shape of the sand particles, gravity automatically find the most appropriate transportation of sand.

NicolasCalvet think in the sand into solar thermal power generation systems thermal storage technologies, operation and cost advantages that you can achieve higher operating temperatures, and lower costs, sand gravity effects can be transmitted easily from top to bottom.

But he also acknowledged that in pushing the sand storage before large-scale commercial application, there are a series of technical and financial challenges to overcome. Major technical challenge in the sand adopted focus sunlight radiation belts, promptly stored thermal energy, as well as how to improve the efficiency of sand when the thermal energy is released.

Calvet said: “we will first of all, we have built the secondary reflection Tower design demonstration projects verify this concept, then consider expanding their scale, by demonstrating the successful validation of the project, we have a more sure of convincing potential investors continued to invest in the development of this technology. ”


SandShifter project

In addition, the United States solar holding company sand differs from the Masdar Institute of technology in heat storage system design, which uses two silos as storage tanks, known as “SandShifter”. The project also won the United States DOE SunShot program funding. The goal is to reduce the cost of storage to $ 15 per kWh or less.

China electric power construction group brief analysis of solar-thermal power generation business is involved

Polaris solar PV net news: on September 29, 2011, China energy development Holdings Limited (commonly known as China can build) and China electric power construction Corporation (referred to as power construction in China) two major power construction group announced the formation of two big corporations huge systems, its affiliated companies, will strike many readers confused about their affiliations. From the perspective of solar-thermal power generation business for China electric power construction including thermal power generation business organizations have done analysis on.

Public information displayed, China electric built is in China water hydropower construction group, and China hydropower engineering consultant group and national grid company, and China South grid limited responsibility company belongs of 14 a province (city, and district) power survey design, and engineering, and manufacturing enterprise based Shang formed, is national funded and by State SASAC representative State perform funded people duties of State owned company, is by approved of national authorized investment institutions, is provides water power engineering and the based facilities voted financing, and planning design, and engineering construction, and Equipment manufacture, operation and management of an integrated construction group. The registered capital of 30 billion yuan, more than 200,000 people, with total assets of 347.4 billion yuan.

Under the jurisdiction of the China Water Conservancy and hydropower for the first China electric power construction engineering company 28 wholly-owned holding companies, most are in water conservancy and hydropower project construction industry. New energy development of China hydropower construction Group LLC is the only company with solar and wind power and other new energy development co, a wholly-owned subsidiary, thermal power generation, there is no light, however that involves, is likely to involve in the future.

Chinese management of electric power construction enterprises, including electricity and water conservancy Planning Institute, China hydropower engineering consulting group limited and its subsidiary companies, totaling 71. There is much more involved in solar thermal power generation of hydropower planning and Design Institute of water resources. Electric power system reform in 2002, water and electricity Institute as an institution approved by the State Council, China hydropower Engineering Consulting Group Corporation is a member institution. 2011 main and secondary reform and power grid enterprises in design and construction integration and reorganization of enterprises, approved by the State Council of China electric power construction scheme of hydropower planning and Design Institute of water resources to managed by China electric power construction and administration.

Hydropower Institute closely related to the National Energy Board, very wide areas of cooperation. Borne is the only hydropower, wind power, solar power and other technical institutions of the Central Administration. Provided including thermal power project feasibility study report and technical review and other services, solar-thermal power generation of code for design of solar energy resources, such as job preparation is dominated by hydropower Institute. Gold v-Aksai 50MW trough solar thermal power plant, first Dunhuang 100MW molten salt solar thermal power Tower and other solar-thermal power project feasibility study technical review are organized by hydropower Institute. Future of solar thermal power generation technology standard and norm-setting, project reviews, and other important work will probably go across the water in coordination with.

In addition to water and electricity outside the General Hospital, with hydropower Institute Office business unit of China hydropower engineering consulting group co to light thermal power generation business is involved. China hydropower engineering consulting group is principally engaged in water and renewable energy power generation projects such as surveying, design, consultation, supervision, examination and evaluation, safety identification, appraisal, construction, project management, General Contracting and related technology and brokerage, as well as rivers and hydropower planning; hydro-engineering, new energy sources and the development of related industries and investment, operation and management services. Its south southwest of survey and Design Institute, Beijing survey and Design Institute, survey and Design Institute of light an investment in thermal power generation business, but are not too large. Other subsidiaries, has not been involved. But its electric power Survey Institute, basic has new energy sources such as solar or wind energy business, with solar-thermal power generation market to improve in the future, its likely engaged in this field.

In addition to the water Institute and the China hydropower engineering consulting group, management of electric power construction enterprises in China also include electric power survey and Design Institute of Hebei province, Hainan electric power Design Institute of Qinghai electric power Design Institute, and a number of design and engineering units, but has yet to see the light thermal power generation has been put into these units.

Dose the energy transition in a turning point in the PV industry in China

Polaris solar PV net news: seeking the domestic PV market requires great wisdom and great strategy epic, grand strategy. Development of new energy needs to reform the old economic mechanism of energy, the establishment of new energy economy system in favour of new energy power. Energy economic mechanisms of change and innovation that involves trillions of energy structure adjustment, hinges on a number of energy interests, vital interests, involving socio-economic aspects. This change does not arise spontaneously, someone must consciously become the driving force for change. Photovoltaic industry has come to the situation the last minute. Photovoltaic companies has been reduced to the brink of bankruptcy, many tiny photovoltaic industry has also been a pessimist to persuade the bankrupt became a bankrupt, like PV loss has arisen now billions of sierbujiang of big firms are shocking. Instead of sitting idle, rather than living for change.

Energy-saving emission reduction targets for the implementation of China’s commitments to the world, strengthening policy support strategy for new energy economy, and relevant State ministries launched a solar roof program. It is understood that the solar roofs plan refers to installing solar power installations at the housing top, based solar photovoltaic technology in urban and rural areas to generate electricity, to achieve the emission reduction targets. Qualifying demonstration projects must be larger than 50kW solar roof policy, that is, installations that require at least 400 square metres area, the owners will focus on public and commercial buildings such as schools, hospitals and Government Treasury subsidies cost could be reduced to 0.58 Yuan per kWh.

Distributed power plant economic benefits

Compared with the widely built large photovoltaic power plant in the desert, rooftop solar building integrated photovoltaics and solar power plants will make it feel more directly into green energy from PV.

In the lateral façade of the buildings with roofs of resources to build small power plants, not only save a lot of power plant construction land, while avoiding long distance electric power transmission losses, reducing the power grid link, saving power input, is technically relatively easy to implement.

Power directly on the roof for the user side, because of its small capacity, no direct impact on the grid, in the case of public power, PV can be used as additional power immediately relieve the pressure of power. Small-scale grid-connected power station on the user side, conditions are ripe, convenience of the grid as long as meet the technical conditions for grid operation, fully parallel operation, this technique has a very sophisticated, power relatively easy to calculate, in conditions of power grid operation in our country can stability grid in the user side.

At present, the distributed model has become the trend of the development of new energy. One industry source said in an interview, European solar power also uses a “distributed development, local power” mode. Germany 2011 PV capacity up to 23 million-kilowatt, already exceed the scale of China’s installed capacity of hydropower station of the three gorges which are dispersed in BIPV/rooftop distributed users to access the system. Owners can create spontaneous use, excess electricity can be sold to the electricity market, lack of electricity supply from large scale systems. This development mode of advantages is: power local elimination na, basic not abandoned light, power get full using; without far distance transmission, so without supporting new large high-pressure, and super high-pressure lost variable electric facilities, save large investment and reduced large transmission loss; power dispersed, so access system voltage grade is low, like in “capillaries system” in run, appeared not stable of new energy power on main grid effects is micro.

According to estimates, a residential building, laying on the roof solar panel, realization of building integrated photovoltaics, spontaneous 40 degrees. If this House is to buy 100 kilowatt-hours of electricity from the grid, you can now buy 60 kilowatt-hours of electricity.

Just think, if the promotion of distributed generation in the country, means that the power supply will be reduced by 40%, equates to a saving of 28% coal-fired electricity, also can reduce the thermal power plants of 30%, this contribution to the world will be enormous. Construction of large photovoltaic power plant compared to the desert areas require high transmission costs, solar BIPV roofing power plant economic benefits cannot be ignored.

Why PV building integration

Because solar energy density is low and highly dispersed, in order to provide the required energy, there must be sufficient acceptance area. According to estimates: in order to meet the 2000 global electricity demand, to solar cell efficiency 10%, need of space for 840kmx840km=640000km2, which is equivalent to Germany and Italy two-State area.

Based on historical data, our 1995 annual generating capacity of about 100 million MW˙h, if all the solar cell power generation, its reception area is about 12500km2, bigger than Tianjin. The above values show that contributed considerably to the size you want, building integrated photovoltaic and efficient use of Building exterior surfaces equivalent was the main way to solve receiving area.

Photovoltaic building integration systems, such as photovoltaic power generation systems for curtain wall, costs and structure design of combination of photovoltaic cells and building materials production process depends to a large degree. Research showed that, if Institute, and building materials producer and PV manufacturer can full collaboration up, building materials PV integration of power unit of manufacturing cost and alone production PV component of cost similar, even than building materials plus PV component of cost also low, and inverse variable and wiring system is can overall into to buildings of power system in the to, so, BIPV of cost may than alone of PV power also to low have more.

BIPV technologies path is most ideal for–CIGS

Academic and industrial circles generally believed that the development of solar cells has entered the third generation. First on behalf of silicon solar, second on behalf of polysilicon, and non-crystal silicon, solar, Copper Indium Gallium se film Sun battery has production cost low, and pollution small, and not recession, and weak light performance good, significantly features, photoelectric conversion efficiency home various film Sun battery of first, close Yu crystal silicon Sun battery, and cost just it of one-third, was called next generation very has future of new film Sun battery, is in recent years research development of hot.

In addition, the battery has a soft, uniform black appearance, is the ideal choice of appearance have higher requirements for premises.

As energy prices soar like a rocket in recent years, coupled with amorphous silicon solar cell prices fell, crystalline silicon module business is growing very significantly, some observers have claimed that crystalline silicon solar power systems may eventually meet the United States in energy demand by as much as 20%.

Compared with conventional PV, CIGS for fewer materials are used in the manufacture of thin film solar cell and thus cheaper. CIGS manufacturing photoelectric materials is made of thin layers deposited on the substrate, and this greatly reduces the use of raw materials. The emergence of new production, including printing and further reduce costs.

Performance of thin-film technology in the near future significant increases in efficiency has become a trend. For example, the CIS/CIGS have been able to compete with the conventional crystalline silicon solar module efficiency. Copper-Indium-Gallium-selenium solar panel can also be made into flexible, the color of its uniform and stable performance, at a press conference, seems much more suited to building integrated applications.

Wang Xiaoyi: first person to eat crabs

Polaris solar PV net news: as utility investors, first consideration must be selected in the same investment costs and efficient power products and obtain a higher output. We is select CIGS as investment carrier tool, is because mentioned of following three a hard soft conditions Xia also has more big power profit space; 1) CIGS and inverse variable device of power conversion rate reached supreme value; usually crystal silicon products and inverse variable device in 95%-96% conversion rate, but we can reached 97%-98% conversion; 2) CIGS design best installation angle, get up most long of sunshine time. Proper design should be more 10% capacity; 3) systems maintenance, properly maintained, lower failure rate, avoiding downtime is too long, can enhance the power of 0.5%-1%.

“We are the CIGS power plant first person to eat crabs, system integration and operation of CIGS has accumulated a lot of experience and data, the CIGS in the future building will be of great help. “Wang Xiaoyi said.

Mulberry trees, blue sky in Beijing-controlled technology, Chief Technology Officer Wang Xiaoyi

Reporter: as a forerunner of the CIGS thin-film technology, automatic control technology in Yunnan Stone Forest Balsam trees, blue sky in Beijing pioneered the construction of 1MWCIGS thin film solar cell power station, will the company is motivated by considerations of how to build this project? You invest in the plant at the beginning, if he considered to possibly fall short of your expectations?

Wang Xiaoyi: mulberry trees, blue sky in Beijing the company decided to invest in CIGS photovoltaic plant three years ago, primarily in recognition of CIGS thin-film solar products can serve as a source of energy power generation. As for your second question, I think any high-tech product must have its market, shows its vitality, to achieve this aspiration, is what we expect.

Reporter: as the operation of the power plant stand, how development? Whether there is a rate reduction? At present is how to stuff? Probably how long can you expect to recoup their investment costs?

Wang Xiaoyi: currently, the grid-connected power station project has been running for almost two years, total power of more than 2 million degrees. Its generating capacity than we expected, 10% per cent higher compared with amorphous silicon products, we repeated this random spot checks, audit data, from daily to weekly, from weekly to annually, concluded that crystalline silica products year electricity 1320 hours and CIGS to around 1480 hours. In addition, the CIGS products from three years of monitoring data, instead of attenuation, power is on the rise, we have had three years of testing data in support of this view, but SI products of attenuation is very serious.

Yunnan stone forest project was introduced by Germany Manz CIGS components, high investment cost, relatively long recovery period, but the research is of great significance.

Reporter: some say CIGS thin film solar cell has the potential to surpass crystalline silicon solar cells and thin film Silicon technologies, next generation leader, do you accept this statement?

Wang Xiaoyi: on a new energy summit in April this year, I raised the CIGS PV is the necessary choice of industrial upgrading and to move beyond alternative to crystalline silicon and thin film Silicon technologies, next generation PV leader in this view.

We currently in a energy revolution era, it including energy consumption way revolution and revolution, and CIGS both can as building decorative material also can as energy material, it of appearance decorative effect very strong, for future of new energy building community, residents with of power is green, and environmental, and low carbon of clean energy, so it is bound to will brings livelihood consumption behavior way of revolution; while CIGS representative of is high-end equipment manufacturing technology, to this for opportunity promoted manufacturing revolution, Industrial revolution and trained to promote industry upgrading of growth.

Reporter: are you as utility investors, whether to continue investing in the future of CIGS thin-film plant ideas?

Wang Xiaoyi: in 2014, our company was awarded the United Nations Industrial Development Organization’s global renewable energy to leading-edge technology with best investment value Blue Sky Award nominations, so we in the field of thin-film battery technology has certain core competencies.

Through the three-year period, mulberry trees, blue sky in Beijing found out CIGS thin film solar cell systems integration technologies, according to our ideas, to new residential building integrated photovoltaics, will all use CIGS thin film solar module, so the company distributed power plant power plant investment in the future is the roof,

Reporter: why did you choose to go with everybody is not the same as the power plant investment route? CIGS thin film is what led you to choose plants?

Wang Xiaoyi: after CIGS thin film solar power station proved that CIGS component has the superiority of Silicon products are not. Silicon industry is a mature industry, and CIGS is a “newborn baby”, it needs someone to nurture, which is the reason why I chose CIGS power plant construction.

Reporter: in your opinion whether the commercial age of the CIGS thin film solar power station has arrived? There are problems which need to be addressed?

Wang Xiaoyi: I think CIGS upsurge of the era of industrialization in the past two years. Amorphous silicon technology development has reached its limit, it must be replaced with new technology, but technology not many candidates with industrialization. Silicon thin film due to low conversion rates and causes of decay, have withdrawn from the industry; cadmium telluride thin-film technology and equipment held in United States on first solar’s hands, but it does not transfer of technology to domestic firms; and concentrating photovoltaic technology, though a high conversion rate, but high production costs, cannot be accepted by the market. CIGS industry alone, not only increasing conversion rates, and high energy efficiency, low production costs, would be a revolutionary technology.

I think, the country should CIGS industry as part of a national strategy for energy security, application a number of national organizations, demonstration, focused research, increase the energy technology innovation support, to promote the energy technology revolution, truly national energy security, green, low-carbon sustainable development strategy.

Lin Junsheng: CIGS thin film solar cell for short energy payback period

Polaris solar PV net news: throughout the entire photovoltaic industry, Copper-Indium-Gallium-selenium thin-film solar cells because of its low production costs, low light stable power generation capacity, electricity generation, energy recovery period is short, the advantages such as widely used, was widely rated as “the future of solar energy.”

Currently China in film solar of market needs is greater than Western, if Government can clear will has environmental, and flexible of, and application widely, variety advantage of film technology route determines for solar industry of development direction, and from funds, and technology, and market, field gives film PV industry to vigorously support, China of solar industry in global competition will be more with advantage, more can led global PV revolution of development.

Manz Asia Deputy General Manager Lin Junsheng

Reporter: Lin, Hello! With the Chinese Government in governance to increase the impact of energy conservation and environmental protection in China this year, and accelerate the pace of structural adjustment of China’s energy supply. “Energy recovery cycle” concept that was widely released in Europe starting in China itself to heat up. Your perceptions of the PV. Judging from the chain length, how would you rate the CIGS thin-film and crystalline silicon solar module Assembly energy payback period?

Lin Junsheng: in fact, the short cycle of energy recovery is the biggest advantage of CIGS thin-film solar, which has been widely known in around 2008, but because of the overall PV market heat large, amorphous silicon product prices are higher, even if time-consuming, energy-intensive production process, few companies would care about this issue. However, with crystalline silicon products prices fell sharply, double flames continue to burn in Europe and America, coupled with environmental protection, energy-saving awareness gradually on the rise, most solar energy experts have to realistic stress next time around and seriously examine crystalline silicon solar module manufacturing process of high pollution and high energy consumption, and so on.

Even the Silicon in recent years claimed a new technological breakthrough, but in General, Copper-Indium-Gallium-selenium remain crystalline silicon technology has about half of the energy payback period, which means that if Silicon take 20 months, the CIGS only take around 10 months. The reason is that Copper-Indium-Gallium-selenium component technology to master a high degree of production process is relatively streamlined, integrated circuit concept can directly on the absorbing layers deposited on glass substrates, which are only

Just in a workshop to complete, so the energy payback period from this point of view, absolutely superior Copper-Indium-Gallium-selenium crystals of Silicon.

Reporter: at present the domestic industry investors there is little understanding of the CIGS thin film industry. Can you tell us something about CIGS, as well as its future investment prospects and commercial prospects.

Lin Junsheng: in October 2013, Manz partner Germany Baden-Württemberg Centre for solar energy and hydrogen research (ZSW for short) broke the world record of Copper-Indium-Gallium-selenium laboratory efficiency and pushed up to 20.8%, a figure not only outsold the polysilicon 20.4% also suggests that the efficiency of CIGS in the actual production level is to go beyond Silicon. In case of not taking into account various advanced technology of polysilicon, the current average module efficiency of traditional polysilicon production is only about 15%, and Manz Copper-Indium-Gallium-selenium component has reached an average level of 14%, so in the next few years, CIGS is bound to catch up with the efficiency of polycrystalline silicon components. In addition, if combined with Copper-Indium-Gallium-selenium special low light and no shielding, CIGS are more suitable for generating electricity. In short, polycrystalline silicon can do, Copper-Indium-Gallium-selenium can do and do even better, but Silicon can’t do it, instead of Copper-Indium-Gallium-selenium specialty, BIPV is one example.

On commercialization prospects view, 2013 for China for is a turning point, while, due to Government of policy support, makes China became global maximum of PV market, 2014 years continued bullish, and Copper Indium Gallium se more is Ming set for support technology is one of; on the, as Copper Indium Gallium se component by needed material of production powers, China especially for development, and deep Copper Indium Gallium se technology.

Reporter: in your opinion, investment CIGS thin film solar cell manufacturing companies should have what kind of conditions? Investment cost-recovery cycle is how long it will be?

Lin Junsheng: first of all, present themselves in the field of photovoltaic companies, they will have a passion for new energy development, and look forward to serving the millions of households to create a better living environment. Current, China PV enterprise more focuses on Yu crystal silicon component of manufacturing, and these enterprise currently are suffered double anti-to effects, Copper Indium Gallium SE for they for, undoubtedly is best investment of new select; addition, on wants to across foot new energy of enterprise,, CIGS is most advanced of technology, and Manz as world only can provides CIGS AC key programme of equipment commercial, future more can will technology constantly to update and transfer to these enterprise. As long as the company has enough ambition and money for new energy, can the CIGS technology with roots in the Chinese market.

Investment payback period, in fact, depends on the size of the input may be, according to the results, more than 500 MW of investment projects, approximately four years costs can be recovered.

Reporter: we all know that countries in the “Thirteen-Five”, clarified the CIGS thin film solar cell development. Do you think CIGS thin-film industries in China’s energy transition and what role?

Lin Junsheng: long chain of crystalline silicon with high energy consumption and high pollution, which means burning more coal and make more electricity, and burning coal yields PM2.5 (less than or equal to 2.5 microns in diameter suspended particles known as fine particulate) one of the main reasons. Twelve-Five before the Chinese Government for PM2.5 problems have not been detailed specifications, thus PM2.5 cause significant economic losses to China in recent years, as well as harm on people’s health. I believe in Thirteen-Five plans, Copper-Indium-Gallium-selenium will be a very important development projects, the Chinese leadership was also bound to strict requirements specification, on the other hand, this is crystalline silicon PV industry a weapon with high pollution and high energy consumption. So I think the Copper-Indium-Gallium-Selenium is the locomotive of China’s energy transition, to lead the new energy into the wider development space.

Professor Sun Yun, Nankai University reminder: SI: environmental issues cannot be ignored

Polaris solar PV net news: in recent years, as countries around the world consistently in non-crystalline silicon solar energy utilization research and development in the field of power, low cost, large areas of CIGS (Copper-Indium-Gallium-selenium) can already see results. Although its market share is less than 15% of total PV market, but with the CIGS technology breakthrough, CIGS solar cells is becoming more alternative to crystalline silicon.

Professor Sun Yun, Nankai University

Reporters: Professor Sun, Hello! Existing pollution in the production process of crystalline silicon cells which link? The current situation? If a technology and equipment are effectively addressed?

Sun Yun: I feel main pollution in production Silicon material this block, because quartz sand made Silicon material of process in the, needs with to four chloride silicon, slightly processing improper, this liquid on easy seeping, pollution around plant, certainly, this problem can in configuration related supporting facilities and management strictly of situation Xia be solution, but manufacturers often will in reduced production cost this a interests drive Xia and “selective” ignored; also, crystal silicon battery production process in the not only high pollution, and high-energy, Silicon of melting point is 1400 degrees, From silica to Silicon, ingots, requires a trip to the purification, need a lot of processes in the Middle, so we usually mean high pollution and high energy consumption is above both.

Reporter: amorphous silicon solar cell production collective pollution is still there? Is the industry’s problems, or the problems of enterprises themselves?

Sun Yun: I don’t think crystal silicon solar cell production is polluting the whole industrial chain, component production, for example, no pollution, diffusion process of acid and alkali cleaning, corrosion, grooving inside will use some pH stuff, pollution is not very big, but still better than films are seriously polluted. Thin-film module cleaning can be carried out on the glass, is often used in organic cleaning agent, not only there is no pollution of acid-base and vacuum coating, so films virtually no pollution in this area.

I think the pollution is their own problem because production pollution no pollution, mainly to see the alignment is not complete supporting facilities, supporting complete implementation, together with strict management, even though production costs may be slightly higher, but pollution problems can be avoided.

Reporter: are you as a leader, your specialty is the study of CIGS thin-film batteries. In your opinion, the technology direction for pollution problems?

Sun Yun: so far, we haven’t found CIGS has serious pollution problems. The past, part of CIGS will use highly toxic hydrogen selenide gas, but due to the treatment unit, emissions should not be a problem. In addition, most of the CIGS cells with a layer of cadmium chloride, about 50 nanometers, the liquid which contains heavy metals, compared to CdTe is still far, cadmium in cadmium telluride 5-8 micron, but sealed should not cause pollution, pollution, Germany and the United States would not be produced.

At present, a number of manufacturers have been using cadmium-free processes, Japan SolarFrontier is currently producing Copper-Indium-Gallium-selenium element, this element does not contain cadmium, which fully reflects this aspect of pollution can be overcome.

Reporter: internally the CIGS manufacturers now produce products containing cadmium which ingredients?

Sun Yun: at present, the CIGS manufacturers such as, place des Vosges and other products should be produced containing cadmium, seen in the domestic similar reports of cadmium free products. We have found, CIGS products containing cadmium conversion rate is relatively high, a higher conversion rate than cadmium free.

Reporter: with amorphous silicon solar cell (module), what are the main advantages of the CIGS thin film solar cell? What are the advantages of better marketing?

Sun Yun: from battery itself for, advantages also is compared more of, first, cost low, we said of cost are is concept sex of cost, now actually also no reached, because it now also belongs to technology hatch period; second, energy low, Copper Indium Gallium se products on in glass, and plastic or stainless steel Shang for processing, whole film plus in together only 3-4 micron, crystal silicon is needs 200 Micron; again, crystal silicon not only material price also expensive, and loss serious, slice process in the saw sewing faded down of Silicon material or can up one-third , Which can no longer be recycled, because many of these powders containing metal components, it is difficult to purify, moreover, need 1400 degree to Silicon ingot, wafer diffusion do then need 900 degrees, energy consumption is considerable. And CIGS whole industry chain in a workshop within on can completed, needs of glass also on 2-3 Micron, cost can controlled, and, production process by needed temperature Supreme only 500-600 degrees; third, conversion efficiency high, currently, CIGS of laboratory conversion efficiency has over crystal silicon, as SolarFrontier has reached 20.9%, and market Shang polysilicon mainstream conversion efficiency for 20.4%-20.5%, produced line Shang, CIGS component efficiency has reached 13%-14% , Even is 14%-15%, and market Shang Silicon efficiency for 15%-16%, more crystal silicon also on 14%-15%; also, CIGS absorption very wide, it can in too Sun Xia 350 Nano near purple outside to 1100 Nano all can has reaction, and crystal silicon in Longwave part is do not to, only reached 900-1000 Nano, non-crystal silicon compared to more weak, only can reached 700-800 Nano, visible CIGS of weak light response very good; last, is most important of point, Is a higher power generation capacity, according to the experimental data, CIGS higher annual output than SI 10%.

In my opinion, market application, is its annual output capacity, BIPV and that it can do, in addition, the CIGS can also make flexible battery.

Reporter: in your mind CIGS thin-film battery technology improved in the future and how much, there is no technology roadmap?

Sun Yun: CIGS industrialization of great technical difficulty, is to a large extent the device, because the equipment is more complex than crystalline silicon, is bound to increase its cost. Equipment, primarily production technology is not yet mature enough, but there is still a large room for manoeuvre in this respect, such as guaranteeing the uniformity of the film, product yield, process stability, and reducing the fault rate of the equipment, production rates, and so on, this column enables you to reduce costs.

I think the core of industrialization of CIGS technology has broken out, because it can be continuous production cells, mainly behind is how to reduce costs and improve maturity issues.

Reporter: what do you think of CIGS thin film solar cells and amorphous silicon solar cell application?

Sun Yun: applications, I think both have their market reach, low Silicon cost and suitable for large-scale building power plants, Copper-Indium-Gallium-selenium can also be, but high cost and curtain wall can be done. At present, SI recession rate this question is very prominent on the market due to mass production, the pursuit of low-cost, product quality much worse than before, and I think the next year or two will appear on the domestic market because of quality problems, such as the recession caused a series of claims, when the time comes people will find Copper-Indium-Gallium-selenium stable performance and low decline rates and other advantages.

The rise of China inverter: big machine small machine wars

Polaris solar PV net news: from 2003 to 2014, inverter with solar PV industry in China for a decade, unlike the component raised after the first tumor suppressor, inverter manufacturers, China does start to obscurity, behind is star-studded. Born, sunlight, change, CSR, Omni g, guruiwate, then to Huawei’s legions, Star enterprise. With components industry, Chinese companies from scratch, from weak to strong, and bring dramatic changes to the industry as a whole.

Unlike the relatively homogeneous components industry’s product line, is, for different power plant applications, many genres of the inverter. Author check out third parties IHS’s standards, and domestic brand of products is as follows:

High power machines on behalf of brands: Sun power, tebian electric, Emerson, Zhuzhou CSR times electric, Corona, jye

Dynamometer representative brand: Sunshine power (read that right, or the Sun), mountain billion, Huawei and other new energy sources.

Low-power machines on behalf of brands: Omni million grams, guruiwate, mountain, Sun, power supply,

Power optimizer representative brand: no representative domestic brands, and did not form a market

Representative of the micro-inverter brands: Yu, Nortel

High power machines, for stand-alone 35KW Central inverter, commonly referred to as domestic “big machine”; medium-power and low-power, single 35KW 1KW and above the string inverter, domestic commonly referred to as “little machines”.

In 2003, the first application of the inverter, inverter industry in China after a long road. Big machine and small machine due to its by for of application environment different, genre of confrontation and development can defines for “three big battle”: 2008 big machine export Spain, 2009 small machine end of began export persuaded stock of abroad customer accepted China products; 2011 before and after domestic big machine became ground station “main forces”, domestic distributed market began punches, small machine in business roof station application in the gradually show advantage, began formed domestic market small machine brand camp, while small machine in Australia, and Netherlands booming overseas markets such as the third stage is a small ground station markets on behalf of brands trying to use, and innovation to develop new technology, this stage can expect more technical route of confrontation. Coupled with a mainstream brand for photovoltaic application philosophy is different, and some respected “set of solutions for all applications”, stressed that “local conditions reasonable proposal” makes the battle more brilliant.

Somewhat similar to the Autobots and Decepticons, isn’t it? And Omega (SMA’s oversized models, GE and other companies) are put into “combat”. Think about it can not help but excited, in transformers 4 coming in June, so I tampered with a favorite line: Theinverters,rollout!

The first war: big machine “counter-encirclement and suppression”, little “sauce”

Is China’s first photovoltaic project in 2003 applied to the Fengxian-10KW series power station, the project is China’s landmark project in the grid-connected PV inverter industry, Chinese brand officially took the stage.

2008 outbreaks on the European market, PV inverter is exported to Italy and Spain, model dominated by concentrated.

In 2009 the Northwest desert station opened as a concession when domestic scale PV applications in the exploration and development, due mainly to a large desert power plant application forms, also related to parallel requirements technical requirements of China, when markets were all made the machine scheme. After development of large applications, technology improvement, and in fertile soils have been developing rapidly in the market.

Before 2009 the inverter in the eyes of most people is a very mysterious thing. In an era of frenzy polysilicon, PV of this money is not an industry, Chinese-made survival difficult. It was an era of popularity of SMA, KACO market in China, with light and power (then “sungrow power”), topasia power represented by the enterprise in an awkward situation. At the time, no matter how large or small manufacturers, the conversion efficiency of the inverter in the first place. From 96% to 98%, but the market lacks a unified tone and publicizing MPPT efficiency, there is focus on the efficiency of the system, but the European market is still the most recognized European efficiency (efficiency of the EU), and a more stringent, but reflected the numbers but not the first two look good.

Customer projects rarely consider the inverter at that time price, picked mostly foreign brands to buy, so that domestic manufacturers against foreign brands every day of “invasion”.

In 2008, domestic PV first started, its domestic market to foreign brands when monopoly, SMA,SIEMENS,KACO, Schneider, POWERONE brand-led enclosure movement of the domestic programs. Domestic enterprises are continually seeking breakthroughs. Its Shi project scale does not big, reached hundreds of KW on can said is big project has, first times domestic brand achieved positive confrontation of breakthrough, is in 2008 years in the, Sun power in bid in the beat at insurmountable of international giant, and with price advantage constantly expanded victories, eventually achieved on overseas brand of encirclement, while also led has some olfactory to opportunities of domestic enterprise entered PV inverse variable device subdivision industry.

Compared with the large machine situation, small machine from scratch is in “sauce” in the process of gradually has been recognized by Europe, Australia and other markets. End of 2009, the huge profits time after the end of polysilicon, has cut the price by almost 80%, PV cost has dropped significantly, according to the cost before subsidies, was more attractive. Markets start installing booms, SMA, KACO, Refusol international manufacturer of products sold after, European and Australian markets was rather reluctant to accept Chinese companies, from large and small aircraft of China got out of hand, and the roof of the family station of the Australian market, basically supporting the whole China in export machine for 90%.

Ai Suo new energy, and later merged with the MV MV Ai Suo, then later acquired by SMA. Chairman of rather beautiful and strong, self-proclaimed grass-roots origins 2009 with “small” a returning doctor Zhao Lei, who founded Ai Suo’s new energy products have just come out, immediately opened the European market. Rather think of the photovoltaic industry hit bottom and will rebound, but I didn’t know it would come so fast, so quickly. End of 2009 until the end of 2011, the inverter industry one of the most beautiful “large Dragon”, Ai Suo eat from head to tail. But in the bigger context, rather incompatible with thinking and philosophy, two split up equally stubborn, rather choose the development cooperation with Dai Guofeng machine, thinking and go somewhere else, and established the ohm after Nick. Can be said to the shocks on Ai Suo has a major impact, in a subsequent development, Ai Suo can only say great, later merged with the MV Al-cable, then MV Ai Suo was bought by SMA. As a stepping stone to open the Chinese market, it can be said is still in the run-in phase, SMA is now something of a feeling of having lost their: first-quarter earnings show SMA sales of 176.3 million euros, compared to 212.3 million euros last year, falling, sales of 1.2GW, down from 1GW, losses increased to 22.4 million euros from 8.4 million euros. For the Chinese market, MV Ai Suo staff quite helpless, an employee of the light says: we don’t know SMA’s China strategy.

Millions of new energy, it is unintentional willow. Was ready to supply Korea market of inverters in the Australian market, “hidden champions”. Origin, Chinese Academy of Sciences, in multi-and Australia boss Cui Peiju working electronic power for 8 years with a dream in 2008 with mountain billion electronics joint venture between mountain millions of new energy, located in Wuxi. Start goal is simple, providing high quality, low cost photovoltaic inverters meet Korea’s booming PV market demand. 2009 Korea Daegu exhibition is very busy, LG, Samsung are exhibiting, but the Museum is still the most Chinese faces, the author was rough estimates there are about 300 Chinese companies.

But Yi’s first customer was a German. When they launched the first generation of home-oriented single inverter after Solarriver, Korea market slumped Daegu exhibition anymore. Billion electronics Korea sales channels advantages no longer, but European markets have opened the door. After the factory in person, Germany customer billion order for the first batch of 500 inverters through Germany marketing springboard, which in Italy opens. In 2011, the back-to-back mountain billion by two investment companies for financing.

Ding Yongqiang, President of guruiwate. Is the youngest of three corporate leaders, born in 80, and man of science. Curriculum vitae simple: graduated in 2005 entered Eton PV inverter electrical engaged in research and development. To meet foreign colleagues contempt for inverter industry in China, stimulus in 2010, combined with several classmates and friends founded guruiwate new energy Ltd in Shenzhen, the “guruiwate (Growatt)”, meaning that customers “additional capacity”. In my survey, guruiwate in the industry reputation. Up to now, the guruiwate global total shipments reached 1.5GW, in Australia and Europe and other major overseas markets and domestic exports in the first place.

Hong Wei, President of Xiamen clenergy, 7 years ago was invited from Australia to return to Xiamen high-tech businesses, production of small machines and frame. 7 years later, Qing Yuan science and technology plan of 150 million a year to the high-tech zone in Xiamen Government of clean electricity. Qing Yuan after a smooth business development in Australia and other places, also plans to make a transition EPC and BT, to provide an initial project development, the medium-term business model combining EPC and the later operation and maintenance. Xiamen clenergy and China Guangdong nuclear-energy cooperation, cgnpc in particular closely, both sides are plan to jointly build a 300MW power plant in Yunnan province. While cgnpc project leader said would have more all-round cooperation with the us in the future.

The four lucky entrepreneurs, there are, whether it is management, research and development was similar to that of industry, they are not lucky early, but just right. Almost always just make products in overseas markets and gaps. But in 2009, the Chinese market after opening, a small machine in the road has been a bumpy ride. While the domestic market has been mastered by Chinese companies say, in 2010, the authors have sought international inverter manufacturers have entered the Chinese market will, their sales representative shook his head again and again, can feel the smile of disdain of the Chinese market has not yet opened, there are barriers of a price war.

A second war: big performance win, small “rural” surrounding the city

After the time skip to 2010, capacity and policy influence components has shown a surplus situation, inverter businesses have sprung up, have appeared, according to incomplete statistics, more than only China has more than 300 inverter manufacturers, often a project bidding up to dozens of companies. Therefore, after diving component prices, inverter prices have also dropped sharply. Apart from Emerson, and almost all foreign inverter manufacturers have given up the Chinese market, while Emerson inverter business is acquired in the domestic roots for many years its power Division (electrical) adapted from, each thinks is always a localization company.

2010 Kono, jye, Sun power, high automation and other enterprise with Sun’s unified bid, launched inverter specifications for standardizing the market at the same time, raise the bar for the PV inverter market. The component led by Yingli, sea-run and three listed Shanghai solar energy technology. Harmonization of the Golden Sun 2010 bid, although it is not an unfair practice under reasonable policy, and the following year, consolidated bidding strongly repeal because of objections, but still has some significance: not to mention the Sun leader, Yingli, the industry leader, Kono has Institute of electrical engineering background, jye are Beijing holding group owned, from quality to size, is the industry leader.

Overseas manufacturers selling industrial products-art prices, manufacturers saw a market opportunity in China. High prices overseas brands, proud as to slow to respond to market demands, in this case, Sun power to rise rapidly, ripped open monopoly markets and international brands to be successful. Sun Power’s success led to more domestic companies quickly followed suit, because of the focus on short-term gains, at the cost of long-term stable and efficient product cheap, partly caused by the deterioration of the market environment. Now, Northwest of a mass before and after 2011 power station had problems. Is reflected in the poor quality of most of the components on the inverter and thermal design is not reasonable, when suppliers of myopic, had dropped out of the market, the owners have to re-buy inverter replacement, paid heavy fees.

In times of active inverter manufacturers, there are many enterprises lose money making Act and let the Sun power is concerned. Simply get into price wars, is not conducive to long-term operation of enterprises themselves and power station, will allow the entire inverter industry into chaos and lack of development, which will affect the entire photovoltaic industry industrial health.

Electricity providers in promoting photovoltaic power plant construction, as well as reducing costs, undeniable, but also brings some risks. Electricity providers much before thermal power the tender system: one-time amount to hundreds of MW and even GW locks at the beginning. Customer’s expectations, often in comparison to a lot of small plants no reasonable offer eager to burst out into a single form, power inverter manufacturers, such as the Sun, these customers are forced to do the chicken, while other items at too low prices, many small plants reach, in addition to the core components, dare to change nearly everything domestic bargains. You know, Sun power companies at least have the advantage of scale, small plants don’t even have this advantage is.

For years, large inverter prices 2 per watt, down from the current 3 hair, most holding the speculation out of the big machine market. Large inverter manufacturers have been outstanding, but at present more than 10 employees.

Many of the foreign manufacturer of the inverter, it wouldn’t pick up the atmosphere to come into China, was obsessed with the inverter is evaluated as high added-value, higher-margin products. But inverse variable device from nature for and no what core of difference, core parts also height concentrated Yu British fly ling, and ABB, and Siemens, several minority manufacturers, inverse variable device manufacturers of difference mostly in Yu Tuo bashing structure, and parts quality, and application design and production tube controlled, in not considered products application accumulated and future continued upgrade of situation Xia, no which home of inverse variable device is not alternative of, so inverse variable device price only will fast fell.

Japan largest turbine manufacturers TMEIC tries in Chinese photovoltaic market share a piece of cake. A company with a company of Toshiba and Mitsubishi origin have achieved global sales of inverter fifth, is currently trying to find the one that fits China’s approach to market conditions to enter the China market. Services from price to Japanese companies ‘ strengths, TMEIC is expected to master the Chinese PV market rules, is now with foreign companies.

In any case, the big machines rely on prices in China fully reverse the situation in overseas brands to monopolize the market and then relying on experience and further improve quality. With market initiatives, and the interaction between the market and market developments in, the development and accumulation of more prominent. In several ways, this machine during development has the following aspects:

Grid stability requirements: big machine has gone through the high voltage and low voltage, zero voltage crossing, massive emergency removal test, the active and reactive power scheduling support, harmonic requirements, continuously upgrade the threshold requirement of inverter technology and the practical application of case references.

Environmental requirements: market for high altitude, temperature, wind, sand and other harsh environments, inverter in thermal insulation, heat, dust and temperature Derating and other natural environments have become increasingly demanding.

Overall programme and costs: bus, power supply, inverter, step-up, communication and other aspects of integration and upgrade, as well as the users of power plant construction, maintenance and cost-reducing.

Go to small angle here. Small turbine manufacturers in Australia, such as family housing in China foothold of power stations and industrial and commercial roofing plant, Netherlands, and Denmark in South-East Asia, Eastern Europe and Africa are more flowering. In Australia, the Netherlands, and several other areas, China’s manufacturers already dominate. Small machines for industrial and services are particularly sensitive, and basically sold through reseller channels, and installers to install and service. Chinese brands to enter the European, the biggest obstacle is the break-through reseller channels and provide perfect service. Due to limited resources, we all consider focusing focus markets: mountain billion focus United Kingdom small machines market, Omni g-focus Netherlands markets, in 2013 sales exceeded 100 million Yuan and Sun from the European Centre for photovoltaic Germany break. In 2010, set up a branch office, 30kW power product in 2013 as a relief in the series sold more than 7,000 units, sales of 200 million Yuan. Billion, Omni g companies by Australia and other markets also established a “pecking order”. In particular, guruiwate, 2011 Australia market share than SMA, Schneider and other international manufacturers, when overseas sales of 200 million Yuan. Chinese enterprises have been completed “countryside surrounding cities”, the next step to do is to enter the traditional Germany, together with the emerging Japan and the United States that several mainstream market.

United States double-reverse, and Germany also component limit after limit, foreign customers are more price-sensitive, Germany, and Italy market, customers in order to balance the cost of component prices, also in consideration of the growing number of Chinese brands. Guruiwate Ding Yongqiang, President says 2014 read overseas inverter 3% per market will continue to fall, because foreign inverter manufacturers have all losses, while domestic inverter price declines may be 15%.

We’ll take a look at the pioneering heroes of the period.

Zhao Lei, ohm Nickelodeon General Manager in Germany for his Ph is professional inverters. After graduation from a corporate operation of the inverter, engaged in research and development into company management. In 2009, Zhao Lei and ningning, who co-founded Ai Suo new energy and as written above, and the two men parted ways after Zhao Lei white founded ohm secondary Nick in Suzhou.

Inverters just at this time when the streets paved with gold, without government support, no money, no staff, in a right time and have no relation to the case, has made breakthroughs in quality, marketing and cost through the Netherlands market breakthrough, and now has for several months as the small domestic manufacturers export champion. Zhao Lei always travelled abroad comes with an outer shell made of transparent plexiglass inverter, weighs 18 kg, core components directly to customers to see the internal structure and annotations, Zhao Lei was the author saw domestic sales of engineering bosses know.

Ouyang Gan, sanjing new energy Vice President, Zhao Lei is an old acquaintance. Also engineering, is currently inviting his mentor Central thousand person plan expert, fellow of the IEE Professor Raymond Lam to develop smart grid control solutions. Sanjing has been doing contract work for renesola recently Icahn acquired renesola 200MW power station, confirms the three Crystal from the side the quality and performance of the inverter.

Meng Guangmin, Al Volt energy General Manager, permanently stationed in Europe is responsible for developing the local market. AI Volt inverter more satisfactory, not originality, but is very tight in the United Kingdom and the Netherlands, and Denmark as compared to a market, has also just sold little machines to the Japan customer, this is very difficult. Japan market there are many hard to get into? Baowei new energy Marketing Director Shi Li recalls her Japan customers from Director to Director, layers of audit, negotiation, adjust bracket cooperation agreement took three years before. TMEIC (Toshiba-Mitsubishi joint venture company) occupied Japan large ground share of 50% can imagine the close of the market.

Meng Guangmin admitted up to now at the domestic market, but still feels a bit not agreeing with it. “I had been living overseas in recent years, customers are mostly foreigners, work straight to straight up. “He said Chinese-style business dealings was not used to. “Fight price, payment term of these things, we can not do without limit. ”

These businesses are in fishing after the gold rush into the inverter business, the market is no longer the incubator, but touchstone, success is not simple.

With increasingly fierce competition in the market, and strategic vision in the inverter part is important as capital and technological strength. 50 million or even 5 million as ohm Nick entrepreneurial success stories, it’s hard to replicate. Market is heading into its third phase.

Ground power station: new applications of small machine?

Small turbine manufacturers has bigger ambitions: replace machine, occupying ground power station market share in China.

It’s not easy.

Their predecessors have been killed on the road. Danfoss, Denmark-descent of the best string inverter manufacturers, is also one of the earliest implementation of distributed company. They maintained a set of single records maximum PV power station–80MW, technology has also been recognized in the industry. But is such a company, too few directly in domestic orders up to 5MW level, final total defeat, Chinese companies were cut. Even overseas Danfoss brands were acquired by other manufacturers, had some record did not market recognition and success.

The author analyzes the causes of small machine promotion:

First, the high initial cost, 1 dollar per watt when little 2-3 money. 2013 4 cents per watt, small machine 1.1 now costs about 3 cents, can talk about 2-8, small machine 6. Calculated on a cost per watt of solar power station 8.5 Yuan last year, the cost of 8%, this year the gap narrowed to about 4%. Majority owner for the initial costs are extremely sensitive, and many owners outsource EPC business, except for small machine often doesn’t run into the owner of procurement beyond the short list, promised price, EPC will not take the initiative to improve the system cost.

Second, application of a lack of market demand, whether in Europe or Australia, owners of station on the roof only when selecting small, rarely large terrestrial power station case. At home, in a large desert plant environment, and at the request of powerful grid access, owners were selected after several rounds of the machines, even in large golden sun roof power station was an early project, or market of choice. Most small aircraft manufacturer when doing distributed, when working with electricity, cramming, “incense temple doors could not be found.” Million new energy and some of the smaller manufacturers such as mountain, guruiwate also produces machines for small machine drivers might not be enough.

Danfoss has encountered another problem in front of small machine manufacturers: insufficient user mindset and learn about new things, big machines in ground solar dominant era, many distributed rooftop projects use big machines. SkyTeam China Southern Sales Director Zeng Yi said: “I was at a project site, look at the edge of a roof there is a great chimney, ask project owners say this why don’t small machines, customers say the roof is so big, that places don’t do it … …. “Small companies often won’t recognize my own voice in the industry and being turned away by customers directly.

Meanwhile, ground power station uses string inverter led to too many harmonics, degrade power quality. Especially after application of string inverters, power grid vulnerable to resonance condition, causing major accident such as power failure protection, which is also the national grid is most worried about the situation. Foreign than 10MW power plant almost exclusively use larger machines, it is also for these reasons.

Huawei’s emergence to market a second look at the small machine.

The SNEC May, three of the hottest topics: money, distributed, and Huawei.

Huawei data revealed in 2013 as the company inverter developments year, when shipments up to 1GW. Huawei’s main source of innovation in the inverter itself signals to the base station equipment and accumulation. “Said photovoltaic application environment, but we do base stations are sometimes appalling, but also not so frequent maintenance as PV, so greater demands on design and quality. “Huawei’s Marketing Director Xu Yingtong said,” we have a dedicated Department in Shenzhen to collect project issues arising around the world, at a time when designing inverters, refer to our past mistakes and various environmental conditions and aging of the electronic components. ”

So when the inverter design program, Huawei has made three major changes: redesigned cooling solutions; without a DC fuse ground and avoid DC arc fault fires, Huawei’s patented intelligent residual current detection instead of cutting technology of RCD and circuit, avoiding likely to cause an electrical accident. According to light and Solarbe.com the results of a joint investigation, domestic PV electric shock accidents have frequently occurred, the writer friend, a colleague in the company, after checking that a roof when distributed PV hands accidentally touch panels, instantly being opened by a stray bullet, if he had not been held by other colleagues as you’re going to fall on the six floor, led to the tragedy.

3rd improved Huawei is using silicon components replaced the brass components, thus achieving 25 inverter life commitment.

In the market, Huawei 500MW small machines are mostly sent to Jordan, and Romania, Cameroon, 15 West African countries, and visibility in these areas, Huawei is far beyond pure inverter manufacturers such as SMA. In the Chinese market, including Yingli, CEO of Chinese entrepreneurs Feng Miao Liansheng, ren zhengfei, is the most respected entrepreneur, articles such as the winter of Huawei, has become the new Bible, be vigilant in peace time. Huawei, a natural in terms of market dominance.

At present, Huawei has once again signed a strategic agreement about 4GW, 1.3GW orders (non-contract). Although ultimately need to project how much concrete implementation, but some users of enthusiasm has been ignited.

Oumunike at a recent press conference, apart from outside their own WiFi and monitoring technology of inverters also compares the string than centralized power generation capacity increased, mirroring the company, generating around 5%.

Improved: the mainstay of the future

Inverter market components, similar to the Internet industry, only know the boss and the customer is the same “no conscience”, lack of loyalty. Largest radio market has been very volatile in recent years, in addition to the sun always wenzuodiaoyutai, top, other top adjustment range is very large. (Over shipment ranking, 2013 second TBEA, the third-place Emerson 2012 second TBEA, the third-place Emerson 2011 second Emerson, the third trillion-Volt) business strategy, quality/design factors, produced from the grounds. Ranking Qian ten of big machine manufacturers in the, special variable electrician thanks Yu group in Northwest in full swing of ground PV station; are Thai inverse variable device in North America market response good, domestic also has are Thai solar help its Digest capacity; South car near two years sales sharply rose of a big important causes is from 2009 began do of many foreshadowing work, like TGP new energy of cooperation has gradually spread; section Novo Albert is is by with EPC improve inverse variable device of sales; Emerson is market share has declined.

CSR also has split up with new energy, signed a three-year joint development of gchl 1GW photovoltaic power plant target. Zhuzhou CSR times electric General Manager Ren Qichang said it wasn’t just the inverter sales, but to go faster and farther in the new energy industry. Delivery 400MW of solar power station planned for this year, but judging from the current provincial slow approvals, difficulty is fairly high.

Power of the Sun is also one of the tallest of these enterprises in marketing. Now many inverter manufacturers at low margins, competitive market environment select EPC+ product model. TBEA 2013 inverters sold about 1.2GW, about 1GW of them own EPC projects did. Shipments of Sun 3.5GW, although also began engaging in EPC business, but last year the sunshine domestic EPC failed to rank in the top ten. Although currently not sure TBEA used its own inverter, but &Solarbe.com in the light of the joint survey found, most manufacturers of inverter power station project is to use its own products and EPC. A well-known inverter manufacturer’s staff and the author said: “you said we now what company? Is the inverter, but 90% of the profits from the EPC. “One word out of the current predicament of the large inverter manufacturers.

That is why, in the face of small machines “Wolves” siege, I think the greater pressure of the Sun, does not like change, Kono, South through the EPC as a car business to ensure selection of inverter cases, Sun Power’s large market share will be directly affected by the small machine challenge.

“Selecting an inverter scheme, depending on the power factors of the application, is decided by the customers and the market. “Sun power solar Division General Manager rushing said,” our studies on the small machine and application experience without losing our achievements in the field of machine. We continue to believe that the ground station is suitable for the use of large machines, small machine programme is to focus on small and medium sized projects unfold the roof edge. “From the date of creation, Sun power has always been a stable China inverter, solid momentum, but in terms of publicity, scholarly enterprises tend to do more introverted that little-noticed sunlight power supply in the industry in 2003, had using small machines, and its main model SG30KTL in the market less than a year global application more than 10000 units.

Before you compare both advantages and disadvantages in detail and published author investigation came to the conclusion: small machines in some emerging markets applications has its advantages, and overall performance in the traditional large scale terrestrial applications better.

I see a small turbine manufacturers have done the data comparison, most is performance a few years ago the most new small machine, while price and technical courses were also earlier, it’s kind of like when you compare the two countries ‘ forces, with their own space to compare each other’s World War II era weapons. While large turbine manufacturers new products over the years, already far ahead of performance.

Look at the size of the development of machine application, is the formation of industry understanding, the key to stabilize the market. It should be noted that small machine today also take big machines a few years ago through upgrading of single power gate, or even power product, used to be a big machine, and today there is a small machine while machine is made by multi MPPT MPPT has developed into a model, modularity of the comprehensive advantages of large machines and more.

Enterprise wrote a few days ago reminded the station owners of traditional box-type inverter station has short life, poor ventilation, and difficult to maintain. And Sun is directly to to market half and the sales over 1.5GW of–SG1000TS of highlight market performance be reply, its flexible surrounded by door and built-in can selected DC distribution and the communications equipment, installation maintenance of convenience sex is market identity; based on minimum standard container of patent outlet, and insulation, and combination thermal design, “thermal, and dust, and maintenance” three big difficulties, was Sun breakthrough improved by resolve.

Comparing string inverter relishes multitouch MPPT solution, in fact there. Sun power May 2014 launch of SG1000TS-M with 8MPPT technology, you can cover a number of different power generation environment, on the one hand taking into account the power losses of the PV string mismatch; the other is more reliable to meet grid stability requirements. For ground stations and slopes and hills are suitable for the application of, enhance cooling and maintenance. Cooling, thanks to intelligent cooling schemes, have better overload capacity, the container itself is a natural insulation, whether winter or summer. Comfortable than little naked. SG1000TS maintenance is very fast and direct-plug power modules can be completed. Ten minutes. Particularly after the warranty period, than in a small machine to replace the machine, is more economical.

Small machines and large battles, or PV programmes in different environments, the confrontation between the two, seemed to last forever. In any case, we are very happy to see the different technical courses and stimulating interaction and mutual progress. Even, occasionally, “catai” is also a major weapon to promote rapid development of the industry.

More with less: large size and micro-inverse

SMA in the recent Intersolar fair in early June, solemn showcased 2.45MW solutions. Even after the merger last year Danfoss solar inverters Division, this Optimus Prime giant is still occupying the Centre of SMA booth location. Until the morning of the first day of the exhibition, was unveiled, and meet everyone.

GE has been announced and the United States cooperate FirstSolar completed the 1500V DC 2MW power levels of photovoltaic inverters and development work, and batch applications in the power station.

Micro-counter to United States Enphase a single show, occupying slightly against the market of North America 80%. But some inverse of domestic manufacturers also developed well, Zhejiang, Yu, Qingdao, Nortel, the Shanghai power represented in 2013 and has a good performance.

For today’s large and small machines is actually being used in the global situation, the author also collected relevant statistical data, with a global scope, China, Germany and the United States four markets wheat machines in different types of power plant application status, each applicable to different scenarios at this stage of the market power basically the same type of judgment and choice.

Large and small struggle, although is technology battle, ultimately it is up to the market, the only criteria. As we start talking about outcome of the Decepticons and the Autobots, not that both played cruel, but by Earth human choices.

California property tax exemption for PV systems extends to 2025

Polaris solar PV net news: following the adoption of a Bill as part of the annual State budget, California solar power systems for property tax exemption has been extended to the year 2025.

Senate Bill 871 (SB871) last week Governor Jerry ˙ Brown (JerryBrown) signed the budget approved for the period. SB871 language extended periods, during which property taxes will not be applied to the “active solar energy systems”, including photovoltaic and solar water heaters.

This exemption phase was originally set to run until the end of 2016-which will last until January 1, 2025. According to the installed property increases the perceived value, the question of whether property taxes can be applied to solar power systems recently in United States, Arizona, also surfaced. In early May, said Arizona property law to re-interpret, could mean the owner rented from a third party system will apply to property taxes.

Analyst firm LuxResearch, ˙ Feinstein (MattFeinstein) received reports in Arizona, the solar industry may suffer such damage of property law to alter or reinterpret, because lawmakers are concerned, these may be better than single solar enacted new laws to tax the power system more easily.

Feinstein said that Arizona’s proposed changes may be “States” in the solar industry and the current United States public sector competition between electricity market monopoly held by another sign.

California news, solar energy industries Association (SEIA), Rona ˙ Lahey (RhoneResch) Governor’s response was to praise Gordon Brown’s actions. He praised the Governor “and lawmakers” vision, and their “commitment to clean environment.”

Lahey said: “the extension of exemptions is not from being taxed by any jurisdiction to obtain funds, also had no effect on General Fund. However, this exemption will reduce the wholesale cost of solar electricity for public sector clients, and reducing barriers to client site project of solar energy. In short, if property tax reassessment, many homeowners won’t choose to install solar energy. ”

Widely regarded as Governor Brown in United States politics, a few years make many efforts to promote solar power. Recent legislation, the proposed House Bill 2188 (AB2188), will simplify the approval processes required to ratify the California residential solar power systems and solar energy to cut so-called “soft costs”. SunRun Walker, Director of public policy ˙ Wright (WalkerWright) earlier this month said that AB2188 may help end the approval process can often become a “bureaucratic nightmare”

Solar-powered smoke: cut one-third city, he moved to Japan market

Arctic star solar PV network news: City solar power first quarter installed volume serious behind, may Xia repair annual total device volume near 30%, plus United States on city solar industry “new double anti-” started zhihou, city lost beauty solar component needed paid AC margin and faced pulled high tax, makes city industry who last week began big cut on Taiwan solar factory turned single volume, became Taiwan solar industry who Xia half performance trend a big variable.

Operators noted that the previously autonomous solar power plant in order to avoid being taxed, have turned a single factory, Taiwan solar cell components shipments, but requires advance payment bond in the United States, together with after tax costs help stimulate, United States market, clients will not necessarily accept the costs. View related variables increases, so that started last week and has recovered dramatically on Taiwan solar energy plant to a single. Industry speculates that land plants this wave effect will not be clear until August.

Result was originally received, another Taiwan solar cell factory orders dropped fears associated with industry in June revenues stop growing, the fate of July see a sharp fall. It was revealed that the city anxious contraction of orders up to the usual order of one-third and solar plant city, 2nd quarter also started moving past most rely heavily on the Japan market, and grabbed a lot of orders, lost a higher proportion of photovoltaics will bear the brunt, firms were forced to cut production in response to.
