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”

CIGS thin film solar technology market potential exceeding 10 trillion

Polaris solar PV net news: according to a report published recently by the global renewable energy development to 2014, according to the 2013 global PV market, its capacity up to 38.7GW, which were added to 12GW, rose 232%, close to 2013, its capacity in Europe put together. From the global PV market with a European core region is gradually moving towards Asia, and China surpassed the old PV powerhouse Germany as the world’s largest PV markets.

Meanwhile, the report shows that 2013 global thin film solar cell production capacity reached 8.4GW, about 4GW, capacity, production is more 20%-2012 film power development was steady development trend in the world. Film generating more attention, with no pollution, low energy and a wide range of applications and the technical advantages of low costs per kilowatt are inextricably linked. From a development point of view, some time in the future, film power there is still much room for improvement and potential.

In recent years, the PV industry achieve sustained development of China is closely linked with the rise of films generating industry and technological breakthroughs. In terms of film technology, Copper-Indium-Gallium-selenium (CIGS) technology is developing most rapidly and is widely used, has become a major film generation technology trends, is now recognized as one of the most promising generation of thin film technology was widely rated as “the future of solar energy.” In this sector, represented by Hina, thin-film CIGS production components of the power plant already has high photoelectric conversion rate has reached 15.7%, and is gradually increasing speed of about 1% per year, estimated 2020 production module efficiency of up to 20% per cent.

Due to the Copper-Indium-Gallium-selenium thin-film solar cells without light-induced decay, radiation resistance, stability and high conversion efficiency is very high and can be made of flexible components, such as unique advantages, Copper-Indium-Gallium-selenium thin-film technology has a very strong market competitiveness, and building integrated photovoltaics (BIPV), flexible roofs, residential areas such as power generation, automobiles are expected to be large-scale application.

Thin film solar power generation technology in building integrated photovoltaic (BIPV) has huge market potential. In broad terms, building integrated photovoltaic (BIPV) is to make thin-film solar power generation panels combined with roof and wall surfaces of buildings, turning each building small power plants, electric power “spontaneous use, redundant Internet access” without covering or long distance transmission. In the industrial field, today most industrial plants using cannot be load-bearing lightweight steel roof, traditional rigid photovoltaic modules cannot be in a typical industrial plant because of the larger mass promotion. In industrial roofing applications, flexible thin-film components using flexible substrates can be bent, you can paste the installation, more promising in the construction market: on the one hand, flexible thin film solar module lighter for the same area may meet the requirement of non-load-bearing weight on the roof, on the advantages that can be bent, you can paste the installation can meet the design and aesthetic requirements.

According to the National Bureau of statistics data, the calculation that by 2020, China’s urban and rural housing construction area is about 89 billion square meters, East, South and West walls area of area of 15% rooftop 10%, direct market size of more than 10 trillion yuan, indirect market size of 30 trillion yuan, equivalent to China’s auto market 3-5 times. Even under the 10% conversions and solar 1300 power hours per year on average, capacity equivalent to 368 gezhouba or 45 Three Gorges, alternatives to 30% per cent of the annual electricity consumption of the whole society needs could reduce carbon dioxide emissions by about 1.3 billion tonnes per year, approximately equivalent to the annual emissions of 20% in our country.
