Innovation Research and development capability to upgrade China PV to the international level should you learn?

Polaris solar PV net news: “innovation is the way out for China PV industry. “The Chinese Photovoltaic Industry Association Secretary-General Wang Bohua recently DuPont Teijin MylariGuard back panel to promote the Conference, said. According to Wang Bohua views and policy, market, cost, personnel, and other factors, China PV industry is a fundamental factor in the development of technological innovation. “In the development of today’s technology, innovation has combined with standards, intellectual property rights, which together occupy the commanding heights. ”

Innovation Research and development capability is yet to be improved

From 2008 to 2013, China’s solar industry has experienced the baptism of two roller-coaster. But in the most difficult years of the industry, China PV technology innovation is very active. Wang Bohua figures show that from 2011 to 2014, investment costs per thousand metric tons of polysilicon production line down 47%, polysilicon production of comprehensive energy consumption dropped by 35%.

Wang Bohua believes that in times of massive losses of enterprises, since there is no relaxation technique innovation, PV industry in China will be able to hold out until now. Since last year, China PV industry as a whole to quickly pick up, to a certain extent also benefit from this.

However, I have to say, China PV industry development capabilities should be improved. According to the photovoltaic industry, revealed to reporters, when some large PV enterprises in building new production lines, are often the first choice of foreign advanced equipment.

Firms do, is based on accuracy, efficiency and reliability considerations. “Our next-generation technology, new materials, new techniques, and even some of materials for semiconductor technology, the basis of a number of key properties, such as the research, compared with the international advanced level, far behind. In terms of special equipment, special materials, there are gaps. Still dependent on foreign markets. “Wang Bohua said.

Giant electronics technology company General Manager Luo Zigui in Shanghai told Xinhua in an interview today that, photovoltaic industry’s ultimate goal is power without the Government subsidies and cheap Internet access and, therefore, any PV photovoltaic back panels must together with its production costs to assess performance. If PV industry cost-efficiency targets are not met, fluorine-containing polymer back sheet and no better value. When using low cost and high performance polyester to manufacture PET backplane, which maintains a stable performance in 25 years ‘ time, and provides good protection for PV modules.

Another noteworthy phenomenon is that in research institutions, especially in terms of key laboratories, gap is also evident in China and abroad. According to the photovoltaic industry’s view, even though China PV industry also has own laboratory at national, provincial and enterprise, but for some high-end technology, advanced technology research, are some of the major PV manufacturers and foreign laboratories in cooperative research and development.

What to learn from the advanced international level

At present, the Chinese photovoltaic industry in the international market, faced with the threat of trade friction-prone, but also faces unprecedented opportunities to domestic policy. Experts pointed out that technological innovation will not only be the basis for future development of PV industry in China, are also core elements of sustainable development.

Gap there, international advanced enterprises of which experience for China PV companies learn from it? DuPont Teijin Europe Chairman JohnC.Miller told Xinhua in an interview today that, there are three key elements of innovation, but they are not sort of priority.

These three elements are: first, we must have very deep knowledge of the market to really understand the market demand, participants in the supply chain and supply chain. Followed by the customer relationship. Interact with customers to ensure research results, also can make development more efficient and faster. Once again is through the development of high technology, to realize the products our customers need.

According to JohnC.Miller’s introduction, Teijin DuPont invested about 30 million dollars a year on research and development. “The product development cycle, generally depends on the complexity of the requirements and development. In General, the development cycle can vary from six months to five years. Some product from scratch, and some products are on top of the material, and other research and development experience in the past, build a new platform to research and development. ”

When asked whether the joint while doing research and development in conjunction with the Chinese PV industry, JohnC.Miller said, DuPont Teijin’s research and development work, sometimes alone, sometimes with some partners, such as research and development company developing. Choice of development mode, on the one hand depends on the opportunity, on the other hand depend on the support or team product requirements of manufacturers, and the project itself.

“I personally think that the global PV market will continue to grow, China’s market will become one of the world’s largest PV markets. In terms of component Assembly, China is now among the top ten markets, will grow further in the future. “JohnC.Miller said.

Renesola refused to India and China

Polaris solar PV net news: citing low profits, component manufacturing, China Shang Yu-hui Sun (ReneSola) has denied China and India offer.

In its 2014 second-quarter results on a conference call yesterday, xianshou Li, Chief Executive, said the company was not interested in simple delivery components as much as possible.

Through the Investors Relations Director LauraChen’s speech, xianshou Li, said: “we now really however much emphasis on quantity and total annual shipments. Instead, we will focus on profit margins. ”

“We refuse to have a very low order of average selling prices and lower profits, such as China and India orders. We focus more on higher average selling prices in the market. Therefore, in General, we only focus on profit margins rather than quantity. ”

The geographical distribution of the company’s business in the second quarter was 40% in Europe, overnight in Japan, China, the United States and other parts of the world the kick.

As India era solar project, this strategy highlighted a problem, its possible for developers to get pressure on supply. Analysis of Mercom warned the company that makes the “bottom”.

The company said it is evaluating its OEM and battery manufacturing capacity in order to adapt to the new trade tariffs. It also revealed that plans to raise its United States market per month, increased from less than 25MW to 40MW.

DanielLee renesola Chief Financial Officer, said: “for the United States market, as mentioned by Mr LEE, 23MW per month. They are our products. They are 100% of the United States, which means they are 100% non-mainland China and not Taiwan battery. ”

He added: “we have been focusing on different parts of the world, focusing on expanding battery production, but in the meantime, the United States anti-dumping policies do affect the Taiwan battery. Taiwan battery prices actually dropped sharply recently. ”

Lee also said that because of its remainder of 2014 demand is expected to improve, the company has established in European stocks.

Solar thermal power generation in China: luck

Polaris solar PV net news: the quiet solar-thermal power generation industry for many years, and finally in 2014 for the dawn.

In July this year, China Guangdong nuclear power Group (hereinafter the cgnpc) announced, delingha, Qinghai province owned by the group a 50MW solar-thermal power generation demonstration project was officially started. In a press release, cgnpc described the project as “China’s first officially started construction of large-scale commercial solar-thermal power project”.

This reporter learned that, the national development and Reform Commission and the National Energy Board is studying price introduced a number of solar-thermal power generation demonstration projects, and to develop the price associated with this policy. Current plans, was launched before the end of October this year a number of demonstration projects, total approximately 1000MW.

Launch demonstration projects, pricing policies, or solar thermal industry in China will usher in a historic moment. Industry insiders speculated that this year and next, light and heat markets will be concentrated.

From a development point of view, China’s solar-thermal power and photovoltaic started almost simultaneously. However, due to the lack of policy support, photovoltaic power generation in China, a single large solar thermal power generation is staggering forward. Photovoltaic and solar thermal differences, briefly speaking, which directly convert light energy into electrical energy, which first put energy into thermal energy, heat energy into electrical energy.

At present, China PV Assembly machine of more than 17GW, but solar thermal installed capacity is still in its infancy stages, most of the pilot project is still in transit, lacks maneuverability in business.

Launched this round of solar thermal demonstration project and photo-electric price policy that will ensure that investors can reasonably measure the return on investment and risk of solar thermal power stations, and uncontrollability of the investment will be greatly reduced. Everything is ready, the East wind, a large number of people in the industry are awaiting policy fall boots.

The first commercial project

Cgnpc delingha, Qinghai project, located in delingha, Qinghai province, solar power base within the planning phase two construction of the trough solar thermal installed capacity of 100MW power station.

This new 50MW trough solar thermal power stations, using high temperature trough HTF concentrated solar technology, supporting the construction of a seven-hour molten salt energy storage devices, annual output of around 225 million, total investment of 2 billion yuan, the project duration 28 months, is expected to put into operation in November 2016.

In fact, the cgnpc once planned for 2012 to start construction of the project, it is clear that today, two years after the conditions are more mature. At present, the project has been declared the first “national solar thermal demonstration project.”

China Guangdong Nuclear solar energy development in Han Qinghao in said in an interview with Xinhua, General Manager, photo-electric price policy is expected to be issued in the near future, the domestic enterprises has basically met the production capacity of solar thermal trough power generation industry-wide chain.

Investors widely expected that associated with solar thermal electricity price policy must be introduced within this year, so that capital market enthusiasm, booster photothermal physical investment. In addition, the cgnpc also carried out within two years, a number of technical tests on solar thermal power generation, “now is the best time to Delhi project work started.”

In delingha solar thermal projects, totalling approximately 2 billion yuan of investment, capital accounts for 30% and 70% of loans from the Asian Development Bank and domestic commercial banks.

Han Qinghao explained that described the project as “the first large-scale commercial solar-thermal power generation projects”, is because of the projects financed using capital and bank loans, pursue commercial revenue after the repayment of the investors, it did not have during the previous domestic solar thermal projects.

This reporter learned that, in solar-thermal power generation has been Guangdong nuclear power as one of the major non-nuclear clean energy strategy. In February 2013, approved by the National Energy Board, cgnpc in Delhi set up a “national energy solar thermal power technology research and Development Center”, for solar-thermal power generation technology development, in addition to 863 solar thermal power Tower project was launched and planned to set foot in the construction of solar thermal power plant investment and overseas EPC projects.

China Guangdong Nuclear solar energy development in the photovoltaic field previously rewarding, especially in the area of large photovoltaic power plant investment competitive. This foray into solar thermal power generation sector, strategic importance than business sense. Han Qinghao admitted that as the development of a comprehensive solar energy company, entered the field of light and heat is an inevitable choice.

Break policies

Many people in Government and business, told reporters that before the end of October this year to launch expected very strong to photothermal development policies, industry-2014 has been called the “first year of solar thermal development of China.”

Solar-thermal power generation in China never experienced, the biggest constraint is the policy. The most direct reference, are both forms of photovoltaic solar power generation. In 2013, in order to absorb excess capacity in State for photovoltaic power introduced a series of policies, including pricing, direct stimulation of the domestic PV market opening. This year, China PV installed capacity exceeds 11GW, almost United States PV module annual production capacity of the company.

At this stage, scenery, such as rapid development of new energy, directly depending on the Government’s policies. Solar thermal industry due to the smaller, three years have not been too many government departments concerned, this is quite different from solar thermal and PV development in China’s most fundamental reason.

For example, most critical thermal electricity price, national development and Reform Commission has yet to give a clear statement. No feed-in tariff, solar-thermal power plant investors unable to risk and benefit assessments of the project, nor to make investment decisions.

Previously, cgnpc, the first charged with solar energy and energy saving, and five power generation groups has the intent of investing in solar thermal, but are carefully tested, large-scale projects have little.

In June of this year, the National Energy Board issued a survey of solar thermal power capacity commissioned letter, the principal electric power planning and Design Institute, national solar power industry technology innovation Strategic Alliance (hereinafter referred to as solar thermal industry Federation) and three units of China water resources and hydropower planning and Design Institute, to mapping the solar thermal industry development situation in China and provide reference for final sectoral policies.

Solar thermal Industry Association said that as of July 15, they issued a total of 124 research form, and 107 of them have received a reply. Meanwhile, the expert group also examined 12 typical companies, data analysis showed that the support and the trough solar thermal power Tower two prototype technology manufacturing industry chain form, the current localization rate is above 90%.

What kind of price should give light and heat? Trade should be given copies of the proposal, the proposed price range, is concentrated in the 1.3 to 1.4 Yuan/degree/degree. Early this year the China people’s political consultative conference proposals, recommended light power price of 1.38 Yuan/degree. China Guangdong Nuclear solar thermal research and Development Center Director Qiu Hemei also suggested earlier in the year, light heat price should not be lower than 1.35 Yuan/degree and offers preferential tax policies.

According to the solar thermal industry Federation calculated that currently light and heat an average generation cost of 1.38 Yuan/degree.

However, many of the experts interviewed said, is about to launch a solar thermal demonstration project price will certainly be lower than the forecast range. “Mainly on account of the significance of demonstration projects in order to spur investor costs while avoiding being too expensive, repeating the solar overheating–overcapacity experience. ”

How to determine the price of solar-thermal power generation at this stage, there are two views of the industry. First, all the photovoltaic demonstration project should implement unified electricity price, and then in the demonstration project experience in introduction of light and heat on the basis of a benchmark price, secondly, demonstration project conditions, we should stick to the “one thing one debate” principle, it is advantageous to industry support role.

Electric power planning and Design Institute, Deputy Director and Chief Engineer, Sun Rui told Xinhua in an interview, said the introduction at this stage does not have light and heat conditions of the benchmark rate. Better approach, based on information on specific projects, according to the debt plus the principle of return on investment determining feed-in tariff.

Sun Rui believes that solar thermal power and photovoltaic power generation there is an obvious difference, the former is much more complex, such as diversity of technical route, length of storage time and address the actual intensity direct solar radiation, air temperature, wind speed, and so on, light thermal power project investment and economic impact. “After the construction and operation of demonstration projects, having acquired experience and study of feed-in tariff issues. ”

What is the advantage of solar thermal

Solar thermal and PV are using solar power, but on the technical principles are very different. The former is solar radiation directly into electricity, which mainstream technology courses are collected through concentrating the heat into steam and drive turbines, which is the traditional thermal power plants and nuclear power plants generate electricity in a similar way.

For thermal energy different ways of collecting, solar-thermal power generation also includes Tower, trough, dish and four different linear Fresnel technology. It is understood that China is about to launch a solar thermal demonstration project to the main tower and trough. According to solar-thermal power powers United States and Spain’s experience, the two highest degree of technology commercialization, the stage can be used.

While the other two technologies, currently not used commercially. Sweden Colin clean can company are attempts to in China market promotion dish type light hot power, the company big Chinese District President Ou Ruilong told reporter, “regardless of in technology mature degrees also is industrialization aspects, we are has do has mass commercialization of prepared”, “Ordos of 110kw of demonstration project Yu September 2012 power, near two years of practice experience enhanced has Colin clean can in China market development dish type sitelinguang hot power of confidence. ”

Ou Ruilong stressed that compared with the trough and Tower, dish-type solar thermal power generation costs in the labor cost and construction cost was relatively small, coupled with standardization and industrialization of production is expected to decline in the cost of this technology in the future will be faster. Technology should be used, and ultimately by the market to make a choice. “Light and heat will definitely compete with photovoltaic power, my solar thermal market in China and very confident in the future of the dish solar thermal power generation. ”

Compared to photovoltaics, solar thermal power generation has incomparable advantages–power-friendly. Considering the intermittent PV, large-scale grid connected photovoltaic power generation must be taking steps, built or equipped with a certain amount of stored energy for peak power station and solar-thermal power generation project by turbo-generator, by configuring the storage system, to achieve 24-hour power and turbine can meet the normal requirements of power system dispatching.

The industry expects upcoming model project Photo-electric price would be at least 30% above the PV electricity price benchmarking, but this does not mean that light and heat less competitive. If the pilot project is successful, smooth development of industrialization, solar-thermal power generation cost will also be in rapid decline.

Sun Rui stressed that simply compare the cost of solar thermal and photovoltaic power generation is unscientific, as both “power quality” is totally different. If you must compare both, based on photovoltaic feed-in tariff, you want to overlay the same thermal energy storage and solar thermal power generation time, corresponds to the capacity of energy storage power station costs, “, the solar-thermal power generation has the absolute advantage.”

Upcoming China solar thermal market is how big? Optimism in the industry of billions of Yuan. This cake will be shared by the State-owned enterprises, private companies, foreign invested enterprises. At present, most of the investors are interested in entering the solar thermal photovoltaic power generation. Ou Ruilong, said Colin clean energy is working with five power generation groups, a number of potential partners to discuss and promote disc-type power generation technology in China.

In the equipment manufacturing business, vacuum heat pipe trough solar thermal power generation, key private parts, for foreign-funded enterprises at present monopolized domestic equipment manufacturers are small batch production, but the long-term reliability of the equipment needs to be tested in the application. Remaining equipment and materials used in solar-thermal power generation have been most widely used in thermal power plants, chemical and other areas, the quality of Chinese products and foreign products is not very different.

However, many industry experts predicted that solar thermal power generation if it is to achieve the scale of photovoltaic power generation in the short term, it will be more difficult. Higher levels of industrialization of photovoltaic power generation, global industrial use. In terms of technology, radiant power PV can take advantage of Sun, without geographical restrictions and building integration can be achieved. Heat and light can only use direct light from electricity generation, only in the DNI (the sun radiation index) up to 1800, has commercial value. Therefore, PV power generation areas, extensive, and solar-thermal power generation is only suitable for building conditions suitable area, and is dominated by large ground power station. In this sense, solar thermal and PV also has a certain degree of complementarity.

II. Technical characteristics of smart PV solutions and customer value

Compared to conventional centralized larger machines as the representative plant smart photovoltaic power stations without increasing the investment, higher return on investment and the availability of a range of advantages, specifically in the following areas:

1, do not increase the initial investment. Smart photovoltaic power stations due to the use of simple design, no DC combiner boxes and DC distribution cabinets, no civil engineering room, part features such as easy installation, initial cost no more than traditional photovoltaic power plant. Also, due to the intelligent controller for photovoltaic (string inverters), small volume, light weight, standardization, through automated production line for large-scale manufacturing, labor costs account for relatively small, has a distinct size advantage.

2, smart internal rate of return IRR PV power station compared with conventional power plants raise over 3%. As a result of multiple MPPT, multi-modal tracking advanced technology, effectively reducing attenuation, inconsistent shadows, construction and installation of the component, the terrain is inconsistent, DC photovoltaic arrays, such as the loss of influence of pressure drop, the system PR (PerformanceRatio) value of more than 82%, compared to the traditional programme average generating capacity increase by more than 5%, internal rate of return IRR climb more than 3%.

3, 25 systems and reliable operation of maintenance-free design. Smart controller used IP65 protective grade, achieved within external of environment isolation, makes devices keep in stable of run environment in the, reduced temperature, and sand, and salt fog, external environment on devices life of effects; system no easy loss parts, no melt silk, and fan, needed regularly replaced devices, achieved system from maintenance; reference Huawei communications base station products global mass shipping and the deployment of design and quality management experience, from devices to system achieved 25 reliability design and the life simulation, plus strictly of validation test, Guaranteed parts throughout the entire lifecycle of the system without replacing, reliable and economical to run.

4, PV power installed capacity of actual utilization rate is high. Smart PV plants average less fault 30% system fault one-tenth for electricity only traditional programmes, the maintenance cost of the warranty period only traditional programme of one-fifth. Traditional photovoltaic plant is essentially a series of systems, DC combiner boxes, DC distribution cabinets, computer room cooling and auxiliary power supply equipment, inverter and other component failures will result in partial or total power loss PV, because professionals need maintenance, repair cycle is long and costly. Smart solar plant is simple in structure, is essentially a distributed parallel systems, a single inverter failure does not affect the operation of other equipment, but due to the small size, light weight, machine spare parts, easy installation and maintenance, and greatly enhance the usability of the system.

5, set of intelligent cascade control and multiple MPPT tracking technologies, power station “visible, credible, and control and controllable.” Smart photovoltaic power plant to enter each string independently of the voltage and current measurement, accuracy is more than 10 times of the traditional scheme of intelligent combiner box times, precisely for a string failures, laid the Foundation for improved operational efficiency. More road MPPT technology, reduced block, and dust, and group series lost distribution of effects, flat terrain Xia electricity upgrade 5% above; in roof, and mountain station in the reduced different towards, and shadow block of effects, electricity upgrade 8-10%; and track system of tie using, track control and controller integrated, can achieved on bracket of independent track, upgrade electricity, smart controller and track bracket became best of partner.

6, smart PV “upgradeable, and evolution”. When technological progress, when the environment changes with Intelligent remote online upgrade controller software, backward compatible design features, without changing the running equipment, upgrades will be able to enjoy the latest technological achievements through algorithms to maximize reuse of existing equipment.

7 carry out friendly, intelligent active power adaptive technology. Use of intelligent controller for high-speed processing capability, higher sampling frequency, control and control advantages, adapt to changes in network, realize multi-parallel better control, better grid harmonic quality to better meet the requirements grid access, improve the adaptability in poor power environment.

8, active safety. Reduce transport distances to realize active safety. Secure transmission and protection of DC is the key and difficult. Design of smart PV without DC bus, string output inverse DC power directly into the inverter to AC power transmission over long distances, take the initiative to circumvent security and protection from direct current transmission problems, reduce safety hazard from arcing, power plants safer.

9, security Dodge PID effect. PID led to of component power attenuation will great of effects investment proceeds, through smart controller automatically detects component potential, active adjustment system work voltage, makes battery Board cathode without grounding of situation Xia, achieved on to are pressure, effective avoid PID effect; due to battery Board cathode without grounding, plus inverse variable device internal of residual current monitoring circuit, can in detection to leak current is greater than 30 Ma of situation Xia, 150ms within cut circuit, achieved has active security.

10, smart and efficient operation and maintenance. Globalization, tiered hydropower station management and operation system, deployed in different locations are managed as a power station power station in logic. Headquarters to globally understand the plant’s operations and earnings, laying the foundations for assessment and management improvement. Distribution in around of station, can through unmanned machine implementation big range of patrol, line personnel through custom of of shipped dimension smart terminal, achieved and headquarters expert shipped dimension team of video, and voice, and location and fault information of real-time interactive, achieved before and after party remote collaborative shipped dimension, reduced line shipped dimension personnel of skills requirements, maximize of complex with headquarters expert resources, achieved personnel of most optimization configuration, improve system of maintenance efficiency.

11, big data analysis engine and the introduction of expert operation and maintenance system, to detect potential defects, mining revenue boost. Through data real-time collection, and cloud storage and online expert analysis system, station can automatically medical, to out based on proceeds maximize of maintenance recommends, as cleaning recommends, and parts replaced and maintenance recommends,, achieved prevention sex maintenance; accumulated long-term operations data, integrated analysis natural, as temperature, and irradiation volume, environment factors, through on smart control unit algorithm online adjustment or software upgrade, makes station in different environment Xia system parts run in best match State, achieved proceeds of maximize.

12, smart PV power friendly to the environment.

Nanhai PV without paying the family also sells

Polaris solar PV net news: every month, families must pay substantial electricity to the power grid company, who lives in shishan Hu Wan Cheng seized on photovoltaic technology “self-sufficiency”, will not only have to pay electricity bills, sell unused electricity can power grid company. As first allowed the construction of individual photovoltaic power generation project in Foshan, Zheng on photovoltaic power generation with confidence, to that end, he gave his own micro-blog named “sunshine Highway”.

Less than 5 minutes to 0.1 kWh of electricity

On Friday, reporters rushed shishan lake view community building 8, 2 seats, just in time for China Southern power grid company staff to install a bi-directional meter Zheng downstairs. Shi Shan power station-related charge, Mr Wong said, install a bi-directional meter is intended to facilitate calculating household electricity consumption and electricity production, subsidies to determine power generation and electricity costs. This marks the success of the household PV power line into the public power grid. It was 3 o’clock in the afternoon, sunlight is better, less than 5 minutes, the “inverter” current display shows the power of 0.1 degrees.

See the number of new electricity meters to beat Zheng face joy bloom. He said according to this efficiency, average about 200 kilowatt-hours of electricity every month. Per 1 kWh of electricity subsidies 0.42 Yuan, in addition to their use, extra at 0.52 Yuan/degree was sold to power companies.

Zheng took the reporter climbed the roof, he told reporters here of ten blocks of solar panels will be installed direct current electricity into the ground floor “inverter” equipment, does not require power storage device directly through bi-directional meter connected to the grid. Reporters observed that neither roof nor the electric box on the first floor near the equipment, do not produce noxious fumes or noise.

Looks easy to him playing with for 3 years

Is such a seemingly simple circuit facilities, Mr CHENG has brewed, preparing for 3 years.

Mr Cheng said, at home generation of whimsy sensitive due to their industry. During the 6 years of working in the PV industry, he found that the domestic industry is growing and technically sound, but the company’s photovoltaic products are mainly sold abroad, only a few demonstration projects in the country. He believes that with the development of photovoltaic power generation in foreign countries and the improvement of national environmental awareness in China, as a purely clean energy in China will have a huge market.

Let him on the visit, but, is the industry upheaval beginning in 2011. “The year 2011 solar panels cost about 16~18/w, which now is only about 4 dollars! “To see the market change from then on he was determined to first assembled a set of photovoltaic equipment in their own homes, and then looking to bring products to market.

Key components of cost reductions brought about by the significant economic value. Mr Bill, past a 200-watt solar panels cost about 3400 Yuan, now priced at only a Board 800 Yuan. 2000 watts of power assembled in his current group, for example, cost a total of 17,000 yuan, and its subject is ten dollars and solar panels.

Photovoltaic power generation thousands of possible

Install the power plant at home has not been smooth. Photovoltaic power generation project construction party candidature as an individual Assembly, some difficulties in the approval process. Lucky is, Shi Shan power supply Bureau in June this year, simplify the approval process, and relaxed the qualification of construction. Package presented by Mr CHENG and design modifications, acceptance of the end of the power supply Bureau of, becoming first allowed the construction of individual photovoltaic power generation project in Foshan.

In addition, he lived in the community building, its roof was a public use. In order to be laid at the top of solar panels, he needed permission from the property management office, for which he also went door to door seeking tenants to sign up to.

Talk about future, Mr CHENG is confident. Foshan, he thinks there are a lot of private villas, housing and enterprises, are suitable for the installation of photovoltaic equipment. With the increase of residents ‘ environmental awareness, PV will be into millions of households.

Install individual photovoltaic systems to urban management department consent?

Polaris solar PV net news: lingji years when a lot of community property owners because the installation of solar water heaters and big legal battles. ||||

In October 2006, Shanghai huahai property prevents you from installing solar-powered by a landlord to court, owner won the final judgment of the Court, the property has no right to interfere with the rights of property owners to install solar. After a series of cases were exposed in various provinces have introduced policies to encourage and support the installation of solar water heaters and even parts of the provision makes it clear that “property not to obstruct.” In market promotion, public support for convenient life and Government in front of each property’s appearance, uniform, security problems can be resolved one by one.

Now, another solar system–solar photovoltaic power is rising and growing very fast, however, as with the original solar water heaters, in the first step in applying for the installation of ordinary people ran into resistance.

On July 22, the Xinmin evening news ran an article entitled the photovoltaic plant is “illegal structures”? The article, reported Shanghai hangtou owners installed solar photovoltaic power generation systems are blocking the property of the event. This article articles caused has many users of warm concern, many industry persons have message: “PV first to get Chengguan of recognized, or to China Chengguan of fighting of strong, residents PV power hard”, and “in PV industry both inside and outside are is embarrassing of situation Xia, hopes various specification measures as soon as possible introduced”, and “so PV policy support not parsnips, also is to implementation” etc. Also pointed out that the owners property block because she occupy places in the garden to build photovoltaic module, “mounted PV is good, but also not be greedy and a roof with a large load in a large, not disguised as unauthorised. ”

In order to better understand the truth of the incident and developments, the author contacted the event–the hero of women, his community’s property manager and Ms Hite to install solar photovoltaic power generation system (Shanghai) co Joe Baker of new energy technologies for specific situations. It is reported that on August 4, the lady has consulted with residential property once again, property allowed to wish her good luck in roof-mounted photovoltaic systems, but forbid their installation in the garden, while ladies feel electricity, only install the roof area is not big enough, still hoping to build photovoltaic modules both in their own gardens. Both sides negotiated without success, the project stalled yet again.

Client perspective: do you own PV systems can be installed in the garden?

Now we look at the position of each party in this incident:

Woman: now stopped. Help me installing solar PV systems company is looking for relevant policies to support, and I also understand the relevant policies, to seek from the relevant Department of the. We are also a private area in the garden, the installation does not affect the other owners as much as possible. In addition, I, neighbours, as well as property and talk again, hoping to solve the problem as soon as possible.

Property: first of all our national policies are supportive, countries advocate new energy photovoltaic development we also know that we know that PV is clean energy, relative to conventional energy, PV now belong to new things, many owners don’t understand that if the owners raise objection, we must fulfill our property to coordinate. Second, if you just installed on the roof and adjacent property owners there are no objections, we will support, but if you need built in the garden, “steel” to install, the owners should first obtain the consent of urban management and other related sectors. Third, in the face of something new, we are also learning and discussion as soon as possible, but you also need the relevant rules for implementation of the policy, can we perform better. In addition, we are now set to such a meeting, with a view to jointly decided by all owners to solve encountered similar situations in the future.

It is understood that the community there are two factory owners and also installed a photovoltaic system on the roof, the property manager said the two installation is no problem, but the two neighbors complained to the response property of the owners, they don’t know the PV, but heard about solar radiation, does not know whether it will cause harm to the human body, so now they don’t agree with. The owners felt that the community at the community’s roof is irregular, after installing PV systems not beautiful, so also objected to the installation.

Joe teacher: I wish her large amounts of electricity, capacity of 28-kilowatt photovoltaic system is installed, because not enough roof area, so it can only be installed in the garden of her home built solar frame. This is a 3 metre high PV mounting systems, and Grapevine, as strictly according to the installation standard installation is no problem, is part of the solar system. In fact, we also help owners installed a sun room at another neighborhood, as long as it is in their own homes is no problem in the region. Property permits, property in the prohibition, it depends. We are now trying to help ladies with this problem, and also representations and local urban management Department, Department of urban management to the Civic Center and housing license back. Now, we can only try to explain to the relevant authorities, try to solve this problem as soon as possible. Hope that Shanghai and Beijing, publishing policy rules as soon as possible to support distributed PV generation.

Related departments: administrative law enforcement Bureau for urban administration of Pudong detachment hangtou Squadron staff said “such a case had never been encountered before, current regulations of this thing was a blind spot, the lack of rules for the operation. “(The original sentence selected from the reports of the PV device is” illegal structures “? Expression of)

In addition to waiting for the relevant industry standards, what else can I do?

So far not solved is one of the reasons for installing photovoltaic systems will build a steel frame in the garden caused by disagreement. From the perspective of property, they just hope to get services for the owners of all about Garden (either public or exclusive) allows to build install need to local urban management department without authorization, on a rooftop photovoltaic system installation, had no objections as long as the owners of adjacent property also would not be opposed. Urban Management Department believes that villa owners over access to Garden only with no equity, should not be allowed to build in the garden, if the ban is illegal. And for the ladies, she felt his large amount of electricity, hoping PV installed capacity larger, part installation of PV modules in a unique garden area also did not affect the neighbors should occupy public land should be no problem.

Build solar water heaters and photovoltaic systems, of course, are not the same, whether city departments but also from beautiful safe garden setting, and other aspects of photovoltaic systems, and to make the final decision. A Netizen said “story used the roof of his home, photovoltaic industry will naturally like Germany that develops, but should not be deformed, destruction of urban planning, the development of private greed. ”

I asked whether the community will install water heater property replied simply follow the standard installation is no problem. “Standard” is the most should be the Centre of attention throughout the event. With solar energy, treatment is not the same, because industry standards did not elaborate and implement.

Property and urban management are aware of national support for distributed PV, but Shanghai distributed project management related Ordinances not issued, their public safety and support in various aspects can only seek a greater number of departments, and wait for the relevant policy. Properties in different way, installing PV systems for enterprises and individuals can only wait.

In recent days, held held in jiaxing distributed PV Conference, Energy Secretary, Wu xinxiong said: quality is the lifeline of distributed solar power projects, the standard is the guarantee of quality work. Local governments should set up mechanism for integrated and coordinated management of the construction and installation of PV, ensure the quality and safety of distributed generation projects. On July 29, the Beijing development and Reform Commission published the interim measures for the management of distributed solar power projects in Beijing, before Beijing, Jiangsu Province, Dongguan, Shenzhen, Tianjin, nearly 10 provinces (municipalities) local management approaches have also been released.

This year, the National Energy Board issued 2014 PV machine planning, all new total record of 14GW (which distributed the 8GW, centralized power stations 6GW), distributed PV highly regarded by the unprecedented, and will gradually replace ground station as the focus of future development of the industry. Just landed with policy refinement and deepening of market adjustments, distributed PV power station will usher in a brand new development space. It is reported that the city of Shanghai has started the revision of the provisional administrative measures on solar photovoltaic projects in Shanghai.

Everything is ready, the East wind. In fact, apart from waiting for the relevant policies to solve industry problems, I think, in more comprehensive policy support prior to the arrival of the photovoltaic industry should also be prepared. Such as professional qualification management, sharing, such as cost control, and personnel training, such as providing more professional promotion and presentation to the ordinary residents (including application installation process and basic knowledge of universal) and so on.

Finally, I note want to install photovoltaic systems or to be personal, it must first obtain the consent of neighbors and property and apply again after a successful purchase of equipment installation, so as not to cause future problems. If you have neighbors ask your photovoltaic system on the human body electromagnetic radiation hazards? You can tell him: photovoltaic power generation system is based on the photovoltaic effect to convert solar energy into electricity, no pollution, no radiation. Inverters, switch and other electronic devices by EM (electromagnetic compatibility) tests, and therefore is not harmful to the human body.

PID say:NO!

Polaris solar PV net news: with the development of photovoltaic industry, PV power station was dropped off from the Gobi desert to sunny inland and coastal cities, application environment causing PV power generation efficiency differences. PID effects component as one of the important factors affecting power plant generating capacity has been widespread concern in the industry. PID effect causes and hazards of what? What programs are the surest way to limit the effects of PID?

1, PID effects what are the hazards?

PID effect (PotentialInducedDegradation), also known as EMF-induced attenuation, is solar module packaging materials and on its surface and the surface of the material under cell under high voltage with grounded metal frame ion migration occurs, and component performance degradation caused by the phenomenon.

PID effects before and after the test parameters for the component in the following table and the I-v curves, “1”, can be seen by contrasting PID effect huge effect on output power of solar modules, PV power plant generating capacity is “the terrorist killer.”


2, why PID effect?

By solar module manufacturers and research institutions of the data showed that PID effects and components, packaging materials, environment temperature, humidity, voltage and are closely linked.

1) composition of solar modules

Solar panel constituted by the +EVA+ cell +EVA+TPT+ glass borders, various parts of the form as shown in the following figure.

Composition of solar modules

2) effects of PID process

Current PID for component effects of real reasons vary, typically explained as follows:

(1) wet, high temperature conditions can produce water vapor, water vapor by silicone sealing side or back panel into the components within;

(2) EVA (ethylene-vinyl acetate copolymer) ester linkage reacts after encountering water, generate free acetic acid;

(3) in acetic acid and a glass of soda ash (Na2CO3) precipitation of reaction Na+, moves to the cell surface by electric field inside the battery, causing vitreous resistance decreased;

Na+ precipitation and the move process

(4) after the United States NERL (national renewable energy laboratory) studies of p-type crystalline SI solar cell using any technology, component occurs in negative bias voltage-induced attenuation of risk. Because boxes around a component is usually grounded PV arrays, resulting in a single component, and borders between bias, so the more closer to the anode output components to withstand negative bias phenomenon is much more obvious.

(5) under the action of negative bias voltage, leakage flow path resulting leakage current by EVA → cells → → → border bracket on glass surface, end up in the ground.

Under the effect of negative bias leakage current path

(6) under the leakage current, positive charge carriers through the glass, by the border towards the ground, the negative charge on the cell surface accumulation, attracting optical carrier (hole) to the n-type Silicon surfaces together, not like under normal conditions flow to the anode (p). This apparent output power attenuation caused by the polarization effect is PID.

3, how to limit the effects of PID occur?

Aware of PID impact effects on photovoltaic power plant generating capacity, limit the effects of PID more urgent. Based on analysis of effect of PID can come up with two solutions, one from a component-side considerations, other is from the inverter side considerations, specific programmes are as follows:

1) from the component side to consider:

(1) non-Na, Ca glass glass body resistance, blocking the formation of leakage flow path;

(2) packaging materials of non-ethylene-vinyl acetate copolymer.

Feature: limit the effects of PID from materials, safe and reliable, but not Na, Ca glass is expensive. Addition of new material stability is also uncertain, and cannot currently be used.

2) from inverter-side considerations:

Using component anode grounding means, prevent negative bias due to leakage currents to form.

Negative bias and bias component PID effect

Features: the solution is simple, low cost, high impact, but negative earthing can cause security risks, threatening the normal operation and maintenance of the power plant safety. After negative grounding of the inverter, if the component is positive ground fault will cause the battery plate a short circuit, and operations staff cathode occurs if exposed to the risk of electric shock, so anode grounding must have an abnormal current monitoring and protection systems, can limit the effects of PID and ensure safe operation of the power plant equipment.

As industry leading of inverse variable device equipment development, and manufacturing enterprise, special variable electrician constantly breakthrough self, innovation seeking variable, through on PID effect for long-term of experiment research and accumulated, development out set can reliable inhibit PID effect of solution programme, it both can guarantees cathode grounding of reliability, and can makes inverse variable device has perfect of protection function, was called anti-PID effect suite.

PID effect Prevention Kit introduction

PID effect Prevention Kit is composed of insulation monitoring system and ground protection system of two components, how it works is as follows:

Insulation monitoring system: suppose the Panels PV+ insulation resistance Rx to Earth (due to negative ground, so there is no need to monitor PV-impedance to ground). PV+ shunt resistor R1 is known first, followed by measurement of parallel PV+ to the Earth voltage, the last Rx value is calculated. Once the Rx is lower than the threshold value, the police immediately shut down the inverter to prevent short-circuit risks caused by insulation resistance is too low.

Ground fault protection systems: GFDI (PVGround-FaultDetectorInterrupter) device by breaking the + high accuracy sensors, interrupting device responsible in case of fault currents, breaking the negative ground circuit sensor is responsible for the detection of anomalous in negative ground circuit. When it detects abnormalities in negative ground circuit current through, instantaneous cutting anode grounded circuit breaking devices, road cut off leakage current circulation, protect the safety of maintenance personnel.

4, conclusions

PID effect as terrible killers photovoltaic power plant generating capacity, the root cause is related to environmental factors and module packaging material. Believed that the future Assembly plant agreed to find a more reliable material from blocking the effects of PID occur on the roots. But in the present, anode grounding is undoubtedly the most dependable way to limit the effects of PID, as excellent inverter manufacturer, TBEA will continue to provide more reliable, high quality solutions.

TBEA-to provide sustainable development in the photovoltaic industry with reliable technical support.

The policy of “warm” distributed PV under usher “Spring”?

Polaris solar PV net news: 7th national energy administration data released showed that first half of the year, nationwide distributed PV on-grid capacity 990,000-kilowatt, which exceeds in 2013, distributed PV new grid-connected capacity all year round. Analysts believe that the policy of “warm air”, our distributed PV or will usher in the development of “Spring”.

Illumination conditions in Western China, and vast unused land, suitable for developing centralized large scale photovoltaic power plant, but high demand for its electricity subsidies, and small local demand, eliminate difficulties. Power demand development in Eastern and central areas of distributed PV electricity easy to dissolve, electricity subsidy demand is low, compared with the photovoltaic plant, used the same subsidy funds to support more photovoltaic power generation project.

In 2013, China promulgated the opinions on promoting the healthy development of the photovoltaic industry, and vigorously develop distributed PV markets, higher electricity price for support in priority industrial and commercial enterprises, industrial park construction scale of distributed PV systems. Support for schools, hospitals, government agencies, public institutions, community building and promotion small distributed PV systems.

China’s great potential for development of distributed PV. According to the National Energy Board estimates, the national building installed photovoltaic power generation for about 300 million-kilowatt, 80 million-kilowatt can be installed just above the provincial level industrial park. Countries also carried out preferential policies for distributed PV. Earlier this year, the National Energy Board annual photovoltaic power generation new record total of 14 million-kilowatt, by which it granted the record size of distributed PV will reach 8 million-kilowatt.

Judging from the data, though national distributed grid-connected PV system annual volume growth in the first half, but 990,000-kilowatt the size of the expected still drop. An authoritative Department source told reporters, taking into account factors such as file size management, incorporation process, new grid-connected capacity in the second half will be much higher than the first half.

But at the same time, access to distributed PV “Spring” of the road will not be smooth. Expert analysis, distributed PV roof facing implementation difficulties, difficulties in access to loan financing, incorporations, tariff recovery difficult, such as an urgent issue.

Among these, the resource is placed in the roof of distributed PV on the path of development the first “pass”. In the recently held a national distributed PV Conference, Energy Secretary, said Wu Shengfeng, Zhejiang Province, Zhejiang Province enterprise’s existing roof, mostly without taking into account the requirements of photovoltaic power generation, load-bearing, leak, security problems exist. Meanwhile, 100,000 square meter roof of large enterprises, the price obtained by leasing roof save no more than 700,000 dollars a year. Without taking social responsibilities and the Government’s push, weigh the pros and cons, and many enterprises are reluctant to provide the roof. Due to the lack of mandatory, photovoltaic power generation project implementation difficulties in the roof.

Unanswered challenges before, “jiaxing model” as a typical experience at this national conference was introduced. Mayor of jiaxing city, xiaopeisheng said that the resources for the full development and utilization of the roof, jiaxing city, provisions on the roof of the new building area of more than 1000 square meters of commercial and the comprehensive energy consumption of public buildings, new year more than 3000 tons of business and industrial enterprises of more than 5000 square roof, according to standard synchronous design and construction of the building integrated photovoltaic rooftop PV. Meanwhile, solar high-tech zone, jiaxing city resources and storage on the roof, roof installation owners signed agreement in advance, uniform roof rentals and tariff concessions and energy policy management standards realized overall grasp of roofing resources within the Park.

In addition to commercial and industrial enterprises, communities and the important position of distributed PV. Energy Secretary Zheng Muchun, Jiangxi province, suggested that residents of countries as soon as possible, photovoltaic power generation of professional policies and technical standards, and should further clarify the preferential tax policies of distributed PV electricity subsidies.

Deputy Director of the national development and Reform Commission, the State Energy Bureau, said Wu xinxiong, National Energy Board examining the adjustment of photovoltaic power plants and distributed PV subsidy policy, promoting cost reductions and subsidies to improve the efficiency of. All local governments should play a leading role. The parties should cooperate closely to promote distributed PV grow even stronger, ensuring that all new PV on-grid capacity by more than 13 million-kilowatt.

Energy “Thirteen-Five” plans emphasize maneuverability will be greater development space

Polaris solar PV net news: recently, the national energy administration Wu xinxiong, the national “Thirteen-Five” speech on energy planning work meeting published in full. Wu xinxiong said during the meeting, the “Thirteen-Five” period, China’s total consumption of energy and coal will continue to control policy. The “Thirteen-Five” Plan 2020 energy consumption control goals and specific implementation path; research initiatives to promote the development of non-fossil energy sources, as well as industrial, construction, transportation and other key measures in the area of energy conservation and emission reduction.

Plan out the door two years submitted to the State Council

“Different from the previous five-year plan, the ‘ Thirteen-Five ‘ more pragmatic energy plan, emphasizing maneuverability. Not just ‘ plan out the door, part science planning ‘ approach, specialized research institutions, the public is invited to participate. Ensures that each index is also able to achieve plan, clearly defined responsibilities, has a specific time schedule, so that planning can be implemented better. “Xinhua School Vice President Lin boqiang, told reporters.

It is understood that in April of this year, National Energy Board delegates power planning and Design Institute, Chinese Academy of engineering, and hydropower planning and Design Institute of water resources and other 16 research and consultation unit establishment of energy planning Advisory Group, as the energy planning of specialized support team. Using the news media, the Internet and other forms, inviting community as “Thirteen-Five” energy plan built to make suggestions, improving planning flexibility.

In the subsequent national energy Board organizational meeting of the “Thirteen-Five” Working Conference on energy planning, Wu xinxiong, planning to focus on nine issues fundamentally solve China’s energy development of the long-term, deep-rooted problems.

Among them, “vigorously promote energy conservation” place first, through scientific and rational use of energy, improve energy efficiency, and strictly control the excessive growth of energy consumption through “one cluster of dual-control” measures, pegged the value of energy consumption and economic growth, and excess of high energy-consuming industries and industrial energy consumption amount control constraint.

Eight other issues are: empowerment of domestic oil and gas supply, clean and efficient utilization of coal, increasing the share of renewable energy, safe nuclear power, expand international cooperation and strengthened oil substitution and stocked up on emergency capacity-building and deepening energy system reform, enhancing energy technology innovation capability.

Wu xinxiong, also revealed that “Thirteen-Five” energy plan to be completed in about two years, mainly to carry out preliminary work this year. By March 2016, the national energy development “Thirteen-Five” planning and drafting stages from March 2016 May 2016, energy development “Thirteen-Five plan” will be submitted to the State Council.

Energy efficient, economical use throughout

Wu xinxiong, introduction, present, the extensive pattern of energy use remains a serious problem. In 2013, China’s unit GDP energy consumption was 1.8 times the world average, United States 2.3 times and Japan 3.8 times, higher than Brazil, and Mexico and other developing countries. In the case of population and growing economy, if the continuation of the current way such an extensive use of energy, energy supply in China find it difficult to support.

“Especially in the last two years a growing smog problem, has sparked the thought of energy use. “The Institute of quantitative and technical economy of CASS Liu Qiang, Vice-Director of energy pointed out that, in order to control smog, take a lot of restrictions on energy use in China: coal, power, vehicle restrictions, such as limiting. “But energy’s top priority is security of supply and provide adequate, safe, clean and efficient energy, rather than limiting energy use. ”

“Take more scientific and rational way, clean and efficient use of energy is the core of the solutions. “Lin boqiang admits.

On April 18 this year, Premier Li keqiang in the first meeting of the new State Energy Commission is also explicitly required to promote energy production and consumption patterns change, set out on a clean, efficient, safe and sustainable energy development path. The Central Finance and Economics leading group meeting held June 13, XI Jinping, General Secretary is raise energy production and consumption to a “revolution” in height.

“For a long period in the future, coal as the main energy does not change, the clean and efficient use of coal resources is the cornerstone of ensuring energy security. “Wu xinxiong said that therefore, coal and power upgrade of energy saving and emission reduction action plan, steadily” coal to electricity “,” coal to gas “as an alternative reconstruction, actively promote the dual coal classification cascade utilization in order to improve the efficiency of coal utilization.

Renewable energy will be more space for development

Wu xinxiong said that due to the current low level of China’s new energy development and utilization, the proportion of non-fossil energy in total energy consumption was only 9.8%, so the “Thirteen-Five” period that will substantially increase the proportion of renewable energy.

It is understood that the new energy plan, hydro, wind, solar and other renewable energies will have a larger space for development–by 2020, to hydroelectric installed capacity reached about 350 million kW, wind power and photovoltaic power installed capacity of more than 200 million and 100 million-kilowatt, respectively.

Wind power development in the first half of this year, the national wind power new grid-connected capacity 6.32 million-kilowatt, cumulative grid-connected capacity of 82.77 million-kilowatt, an increase of 23%, extending a 2013-year rapid growth trend, continues to maintain 20% pace.

First half of 2014 national new PV on-grid capacity 3.3 million-kilowatt, about 100% than a year ago. When cumulative kWh photovoltaic power generation by about 11 billion-kilowatt, an increase of more than 200%.

Judging from the data, though national grid-connected renewable energy added capacity is greatly increased in the first half, but still fall for the intended target. One pundit told reporters, taking into account factors such as file size management, incorporation process, new grid-connected capacity in the second half will be much higher than the first half.

It is worth mentioning that, Wu xinxiong, proposed, to adhere to both centralized and distributed, the development of distributed PV as an important means to advance the revolution in energy production and consumption in China.

However, for renewable energy, especially wind power, photovoltaic, desert wind, abandon light phenomena has been the rapid development and grid connection problems cannot be effectively solved, struggling for renewable energy development.

Wu xinxiong said that to strengthen the power grid planning, positive development of smart grid and scientific arrangement in peak load, frequency, energy storage capacity effectively abandoned, abandoning the wind problem.

Online test screen printing wet weight of functional significance for crystalline silicon solar cells production monitoring

Polaris solar PV net news: in the production of crystalline silicon solar cells printed, online test printing function of wet weight for both traditional printing equipment down time measurement can be avoided printing wet weight impact on the production, and provide on-site technical staff monitors the production line running provides a technical means. In the print production process in the future to improve equipment utilization and to collect real-time printing data play an important role.

1, printing equipment in the monitoring on the market today printing problems faced by wet weight

Under normal circumstances, in crystalline silicon solar cell technology in the production process in order to understand the State of crystalline silicon solar cells printed quality, in a specified time period to monitor the print aspect ratio of wet weight, and grid lines and measurements. As we all know, traditional screen printing equipment currently on the market use in each monitoring must be to pause printing equipment, and then manually add test wafers, printing of data measurements. If printing wet weight monitoring every half an hour, will result in about 1 minute of downtime. Provisions such as a factory site once every 30 minutes to the current print quality control, each device each time will lead to 1 minute of downtime. 20 hours a day and loss of production time will be because the process control 20*2=40 minutes, if calculated according to the capacity of 1400 pieces per hour, each device will vary by data-collection capacity loss of about 900. If you have 8 lines of workshop, will be printed daily wet weight loss 900*8=7200 loss of capacity for data collection. If you are using the print device is a 4-bit, it will lose more production (about 28000).

If printing equipment with 4 printing table, and every time you want to print on each table measured wet weight, if no print parameters to adjust each wafer wet weight after weight testing to printing before printing test takes 1 minute, 4 takes about 4 minutes after the end of the test.

For c-SI solar cell producers, printing process stability is directly related to the solar cell product quality stability. Thus, each company applies quality management techniques to monitor the printing process the data related to the trend. However, due to the drawbacks of traditional print design, timing data acquisition will be great impact on production, we often find that many need to monitor the data either on the production line is made up of employees or employees in order to achieve the production targets are not monitored.

2, tested of JRT user-friendly online printing wet weight design

Test print is about problems in order to avoid downtime, JRT in online testing next-generation printing equipment integrated wafer printing function of wet weight.

Realize the fundamentals of online testing solar cell printing wet weight:

In equipment of printing processes Shang material segment and Xia material segment integrated two a specifically for test wet heavy design of drawer, as Figure 1 by shows, operation employees will advance said heavy good of wafer into printing Qian of Shang material drawer (loadingdrawer), select specifies test of press (such as Printer1), wafer will will automatically transport to developed of press (Printer1) completed printing, zhihou automatically entered Xia material drawer, led bright up, reminded operation personnel removed completed printing of wafer. (The exact schematic is shown in Figure 2) the last manual measurements calculated printing wet weight. During the test device will not stop production because of the measured wet weight and operating employees in the production process in accordance with the factory set monitoring time put Silicon on time in wet weight monitor drawer you can quickly access each press on current print wet weight.

Figure 2: analog monitor printer (Printer1) wet weight of the printing process

Field operations staff, you also need to spend time in silicon wafer weigh. If it happens to appear some time printing quality problems, and measure the mass wafer operators are doing work, failed to stop in time, there will be possibility of poor printing solar cells. Given the existence of these problems, JRT printing devices can also function of automatic weighing, printing wet weight measurement will not only avoid the downtime effects on yield, and avoids on-site operations staff when wafer weigh in on lax regulation of printing equipment, achieved the goal of printing production real-time monitoring.

Specific equipment achieved process as Figure 3 by shows, operation employees will wafer into printing Qian of Shang material drawer (loadingdrawer), select specifies test of press (such as Printer2), wafer will will automatically transport to integrated in equipment in of electronic said Shang for said heavy, completed said heavy Hou, wafer was transmission to developed of press (Printer2) completed printing, zhihou automatically entered Xia material segment electronic said heavy completed said heavy Hou, wafer was transfer to Xia material drawer in, Indicator lights up to remind the operator pulled out after printing Silicon. Test printing wet weight will be recorded in the computer, specific values will be displayed in the user interface.

3, online printing of wet weight monitoring function on the actual production of meaning

Online test screen print function of wet weight, avoiding conventional printing equipment needs to stop testing the effect of improved equipment utilization, reduces the cost of enterprise average.

Secondly, technology workers, in daily Web version of the experiment, slurry tested in the work of other processes, such as optimization, online test screen printing wet weight functions can be in does not affect the production of case for process analysis to provide additional printing data, facilitate future process improvements and experiments.

With the advancement of device intelligence, online test screen print function of wet weight must be the necessary functions of c-SI solar cell printing equipment, in crystalline silicon solar cell production in the future, it will play a pivotal role.

“Jiaxing Conference” what brings to distributed PV?

Polaris solar PV net news: August 4, simmering nationwide distributed photovoltaic field seminar held in jiaxing city, Zhejiang province. Conference talk in jiaxing in promoting distributed in photovoltaic development out of the conundrum of many innovative practices, at the same time share companies such as Jiangxi, Guangdong, Jiangsu and Shanghai Automotive Industry Corporation of distributed PV development experience.

This Conference not only attracted people from all over the country’s energy system nearly 200 participants, but also by the unprecedented attention of the industry. Industry experts interviewed said that mode will learn experiences of distributed PV development in jiaxing, and transfer policy information, distributed PV in the future will also bring about a positive development.

Expanding the scope of distributed technology available

At the meeting, national energy administration Wu xinxiong, the National Energy Board issued the notice on further implementation of distributed photovoltaic-related policies (draft for soliciting opinions) key terms of confirmation. He made it clear, fish ponds, lakes, beaches, and mountains left, agriculture greenhouses into the resources construction of photovoltaic power generation project, 35,000 volts voltage connected to the grid, project capacity not exceeding 20,000-kilowatt, perform local PV benchmark pricing policies.

In addition, the “spontaneous personal use” low, load instability or solar businesses and power users cannot perform energy service contract item, executable PV benchmark price policy, PV power generation by the local power grid enterprises according to the regulations of the State of the local benchmark price policy full purchase of photovoltaic power station, will not enjoy the country distributed PV subsidy policy.

The National Energy Board said, considering the characteristics of the domestic PV market the changes expanded the scope of distributed generation technologies available, to break the bottleneck of current distributed PV development, enhance and mobilize the enthusiasm of investors, promoting the development of photovoltaic industry.

Positive evaluation of enterprises in the industry believes that this is the relevant government authorities to fully consider the reality of distributed power generation system stakeholders, to fine-tune policy based on industry practice, conducive to the PV industry’s sustainable development. Sun Power Corporation General Manager Cao renxian says: “policy adjustments to those light resources well, but projects with insufficient load, will release the larger market. ”

Yen duyet SAIC Shanghai energy conservation technologies General Manager Zhao Xinhong told reporters: “the SAIC’s vehicle logistics parking lots around the developed coastal regions, covers an area of more than 5000 acres, land for land is for industry, construction of large parking sheds, but lack of electricity load. Policy changes expanded the scope of our building, SAIC plans to build three years distributed PV 200 MW, 2020 to produce 500 megawatts. ”

Other experts point out, the policy change does not affect the “spontaneous personal use” form of development, spontaneous personal use is still encouraged distributed an important direction of the country, State-subsidized policies unchanged. Only for “spontaneous use of” low, load instability or solar energy services for businesses and consumers unable to meet contract projects, implementation of PV benchmark pricing policies, to provide investors with reasonable, “backing” returns expected, increase the attraction of financing.

Follow-up will also strengthen policy support

“Jiaxing Conference” brought positive energy to distributed PV, but then has to make multilateral efforts and perform its function. It is reported that the national energy Bureau and the Ministry of finance, national development and Reform Commission on ensuring electricity and State-subsidized funds on a monthly basis (or agreed) settlement, numerous conferences, “allowing investors to see the concrete results of the national policy, stimulate the enthusiasm of investors.”

Wu xinxiong said that national energy policy Bureau, to do the work of six caught after landing. Which including focus research and implementation can renewable energy quota business, promoted “new town, and new energy, and new life” action plans, carried out concentrated type and distributed PV power subsidies trimmer of research, and discussion possibilities and the approach, green County City by brand standard in the joined non-fossil energy using share,, established equipment component Enterprise evaluation system, promoting enterprise fittest, organization carried out distributed energy planning, and plans, and grid service, important matters of regulatory.

“Parties to work together in close cooperation to jointly promote distributed PV grow even stronger, ensuring that all new PV on-grid capacity by more than 13 million-kilowatt. “Wu xinxiong said.

A component company official told reporters, currently being distributed early stage of industrial development, industrial management at the exploratory stage, to the confidence of industrial development.

Local governments or enhanced support

Allows local governments to play a leading role, was one of the meeting passed important information. On one hand, the National Energy Board affirms xiuzhou mode, local government organizations, roofs using problem-solving practices, on the four provinces of Hebei, Jiangsu, Zhejiang, Jiangxi, Vice-Governor of the heavyweight official participants and field position, full of leaders of provincial energy departments, or after the meeting will launch a local photovoltaic distributed a small climax.

National Energy Board also made clear in previous filings, local governments must focus on key areas of distributed PV application. Encourage roof area, the load zone of the large, high power prices and large businesses lead in the PV applications. Encourage local governments at all levels on national price subsidies on the basis of supporting the financial subsidy policy, on schools, hospitals and other public institutions, and affordable housing and distributed PV power generation increasing support in the countryside. Encourage railway station (including the high speed rail station), Expressway, airport terminals, large integrated transportation hub construction, large stadiums and parks and other public facilities systems, distributed photovoltaic applications.

A distributed development enterprise in Jiangxi province told reporters that local energy authorities for support and management of distributed PV capacities vary. “Some simply play a coordinating role by the Energy Department, if the next can build long-term working mechanism, through the process, will be more conducive to our work. “Jiangsu company also said that local government support should not be limited to the Energy Department. “If local governments lead by example, and local government agencies laying the roof of the Office building of photovoltaic panels and roof offers to the enterprises, and more than ever to show Government’s support and commitment. ”

Frequency of distributed PV demonstration area “zero” malicious competitive breakthrough profit bottom line

Polaris solar PV net news: 4th seminar of the National Energy Council, further promoting the development of distributed PV. Reporters recently in Wuxi, Nantong, two first national demonstration zone of distributed PV interviews found that Governments and businesses are fully aware of the significance of this layout, but in the process remain multiple barriers to progress than expected. Stakeholders recommended that further raise barriers to entry, optimized financing platforms, enhancing power grid support, demonstration zone of experience spread out into a “prairie fire”. In addition also with the integration of new town planning to achieve in large power plants and distributed generation in the East of the West go hand in hand.

“It’s hard to profit” remains a demonstrations area maximum constraints

Compared with the large power stations, distributed PV realizes every building, every piece of suitable land, diversification of production, use, particularly suitable for limited land resources, relatively high electricity prices, industrial size larger in the East, can improve the energy structure, and will also become a new growth point of China PV industry. August 2013, the National Energy Board issued on application of distributed PV demonstration area construction notice, determine the first batch of 18 demonstration garden.

As one of the first pilot, Nantong economic and technological development zone project by zhongtian photovoltaic technology limited implementation. Reporters learned that the company had in industrial plants, office buildings, public buildings roof construction of photovoltaic power generation system, cumulative installed capacity of 11.65 MW to date, from the perspective of project signed in 2014, will be completed by the end of 80 MW total installed capacity, in 2015 the 150-megawatt demonstration project.

“Our progress is slower than expected, but in 18 Park good, related departments in the first half when the checks, some Park ‘ zero ‘. “Nantong Sun Xing said the Director of energy transportation, 150 MW in Nantong in the demonstration zone around large scale, in the process of the biggest constraint continues to be” difficult to profit “.

As principal owner of the Nantong model project, transit technology group limited Director Cao Hongbin told reporters the new energy industry chain, distributed PV return on investment risk, there are several reasons: lower rates a spontaneous personal use. Some 1-2 day off per week, plus statutory holidays and annual maintenance time, averaging less than 75% spontaneous use of enterprise. Second, electricity prices low for public buildings. Resources for schools, hospitals, Government and other public roof, good project implementation conditions, but the lower tariff charges, local absorptive photovoltaic electricity prices industry electricity price gap between relatively greater, even electricity price gains. During the third power station operations factors beyond their control. More power station 25-year lifetime of variables, providing roofs enterprise business risk, aging, sustainable and stable effect of photovoltaic power to dissolve or even power outage due to the relocation.

Wuxi demonstration district of demonstration scale is 50 MW, progress also than expected, its head and Cao Hongbin, are proposed, national demonstration District more is exploration experience, temporarily not profit is in expected within, let they confused of is another two a problem: first, demonstration district both inside and outside of electric price subsidies standard are is each kWh 0.42 Yuan, other the policy also basic as, addition, although half progress more slow, but recently of PV power construction and industry development symposium proposed, to insisted completed annual PV target, Also means that usher in the period of intensive construction in the second half.

Cao Hongbin told reporters that countries intensive support policy for industry is a good thing, but need to be alert to a further bout of distributed PV competition, after all, quality roofing resources limited, and Rob banks without cost when an iron grip. In fact there are such signs, and roofing business negotiations, according to the General regulations of the State can be 10% off, but the model district enterprises 85 percent or 83 percent, which broke through the distributed profit line, which belongs to the competition.

“Downstairs to dissolve” to “dissolve” the required threshold several

Demonstration area of Nantong, Wuxi has a certain universality. China’s hydroelectric design and Research Institute of Water Conservancy in May reported, though to various provinces and cities in China earlier this year distributed annual construction guide universal large scale, but the speed is also far from ideal, facing low yields and difficulties in finding, financing difficulties and recording, the roof load cannot guarantee long-term stability, and many other issues.

Many from members of the industry, from the development of the 18 pilot projects, distributed PV in actual operation there are three main aspects of the problem. First, the tariff billing and recovery more difficult. Current investors and the companies directly to settle electricity bills, there are many factors beyond their control, electric company of poor management or reputation are not high electricity bills in arrears, lack of legal constraints, and termination of electricity companies after the power still available to purchase from the Internet, is not conducive to power plant investment recovery Fund.

Second, roofing resources difficult to implement. After survey row touch, meet “load full”, and “power spontaneous use 90% above”, and “25 enterprise operating status good”, and “electric price reasonable”, all conditions of quality roof resources less, basic meet conditions of roof owners in chat in the and on whether produced security, and anti-leak, problem exists more concerns, participation enthusiasm not high, especially some SOE, internal program complex, communication difficult. There are some companies, proceeds on the roof the asking price is too high, it is difficult to implement.

Third, the financing is still not perfect. “Because previous lessons, many banks for PV is still scared. “Cao Hongbin said that 18 demonstration area said CDB has support, but how clear and how progress there are no rules. Zhongtian technology rests entirely on the Group’s liquidity was doing demonstration projects currently invested 120 million Yuan, 80 megawatts expected to invest 640 million, “If there is no better investment platform, too much pressure on the company. ”

Reporter understanding to, distributed PV power operations mode is “spontaneous use, and allowance Internet, and near elimination na, and grid regulation”, in must regional within formed “near elimination NA” is ideal of status, but due to above several obstacles, currently also no enterprise can achieved “near elimination NA”, basically only do “downstairs elimination NA”, next must improve elimination na proportions and development benefits.

New town into promote new opportunities

Cao Hongbin, who believes that countries are gradually distributed PV policy, believe existing barriers will be gradually solved, the recommendation is to adhere to “step away” before the institutional mechanisms for straightening out to avoid a “step too far”, should be in accordance with the “model to explore-universal-expanded to more enterprises using” steps forward, and in a number of ways to improve.

One is the diversity of investors. Cao Hongbin said, distributed PV was mainly propelled by the National Energy Board, use the lever to adjust, but only so far enough. Hoping to combine provincial and municipal energy conservation standards, increase the amount of distributed PV market and, in addition, for high energy-consuming, distributed PV installations for power supply enterprises should explicitly use the indicators, and as one of the assessment criteria, which made investors more diversified, for example Central enterprises, members of the State-owned enterprises, there are sources of foreign-funded enterprises.

Second is the enterprise “wide temper justice with mercy”. While to improve entered threshold, let real has responsible, and has capacity of enterprise to do, after all distributed PV profit General to 78, if only is wants to using offers policy, and “earned a put on go”, such of enterprise came in more has, is may again appeared Qian years PV of lessons, on the, for real concentrate on do distributed PV of enterprise, recommends as soon as possible refinement national of support policy, place also can introduced related supporting facilities.

Third, further enhancing power grid support. Building intelligence within the distribution network is to achieve regional “absorptive” condition. Research on grid-connected distributed generation and control of key technologies and applications to address new energy security and management problems with the access to the distribution network, flexible access to achieve energy security. A case study of State grid, Jiangsu provincial power company, and now it is focused on creating a first-class distribution network, the “mind power, saving money, green” goals.

In order to better promote the development of distributed PV, many industry insiders also can be combined with the new urbanization. Chinese Academy of Sciences, Director of the Institute of electrical engineering the original Li Anding told reporters that rich solar energy resources, and land costs are lower in Western, vigorously developing large power stations, in contrast, in Central and Eastern provinces such as Jiangsu, the new urbanization of distributed PV provides a new space.

Li Anding says, currently in planning of new town construction in China still mainly rely on State-building, in the older ways of transmission, not combined with the new energy industry. In the old town development and construction of distributed PV benefits Division problems, more difficult to implement, and the construction of new towns does not exist such a barrier. Encouraging urbanization construction distributed in photovoltaic systems in new and exemplary construction plays a leading role, be prepared to summarize and advocacy, providing references for the construction of other new towns.

Hanwha Q CELLS plans expansion

Polaris solar PV net news: headquartered in Germany hanwha QCELLS (HanwhaQCELLS) has revealed that expansion plans beyond 1.5GW the end of the year.

The company said its hope that through a combination of new production lines in existing factories and efficiency measures, improving the capacity of approximately 1.1GW.

In Malaysia, the company said, which is nearing completion of its new 204MW product line, which will make its main producer of Cyberjaya’s ability to operate up to 1.1GW.

Meanwhile, hanwha QCELLS, said it also aims to implement “manufacturing excellence program” to improve the Malaysia and smaller Germany factory output, respectively, to raise its output to 200MW and 30MW.

Flourished in QCELLS2014 first half of the year, supported by, the proposed increase to achieve, the company says, it has shipped 593MMW, up 68% from a year earlier.

Jin Xi喆, Chief Executive, said: “hanwha QCELLS to further expand its strong position in the international PV market. In our high-quality PV products and solutions under the background of rising global demand, we will further improve our national capacity. ”

In view of its Europe and Malaysia country of origin, if later this year to pass the United States to China and Taiwan impose tough solar imports preliminary anti-dumping and countervailing duties, hanwha QCELLS will become one of the beneficiaries.

However, even if the announced capacity expansion impossible enough to hanwha QCELLS take full advantage of the ensuing United States massive rise in demand.

However, the company’s latest expansion plans on behalf of QCELLS brand reversal of fortune in 2012, when the Korea Han hua group to acquire the bankrupt Germany company, the brand was rescued.

United Kingdom early termination of the solar PV subsidies project mad rush

Polaris solar PV net news: the last decade, United Kingdom Government to vigorously develop renewable energy projects, especially solar power, more endless subsidies to new energy enterprises. However, the United Kingdom Government has recently proposed to end subsidies for solar companies in advance, in order to reduce costs. Solar energy companies believe that doing so is illegal, to get the Government to change this decision.

Journalists learnt from August 4, the Gulf News reported: the United Kingdom Government has recently proposed to terminate corporate subsidies for solar power, which prompted United Kingdom’s four largest solar companies dissatisfied with, and asked for a judicial review. Last month, United Kingdom Supreme Court ruling: the Government does not comply fully informed of the purpose and intent of the solar subsidy cuts obligations.

These four companies namely, Solarcentury, TGCRenewables, LarkEnergyandOrtaSolarFarms. They are currently working with the authorities to undertake negotiations on this proposal. It is reported that subsidies for renewable energy development projects are aimed at capacity of more than 5 million Watts so Enterprise subsidies, subsidies planned deadline until April 2017. But now the Government is planned for April 2015 on the end of the subsidy. The project started in 2002, implemented largely stimulated the United Kingdom power plant investment, greater use of renewable energy to increase electricity supply.

In May, the United Kingdom made proposals on energy and climate change ahead of the end of subsidies for the project, aimed to prevent a sharp rise in the cost and ensure that there is sufficient funding for low carbon technology projects. It is reported that as early as before that solar subsidies has made policy changes had a dispute with the Government.

Solar companies to argue that this is not in line with legal requirements, and reduce a lot of job opportunities, while the solar industry will increase the cost of hundreds of millions of pounds. If subsidies are terminated in April 2015, tends to cause the currently approved solar construction project in less than a year’s time in the mad rush, it would certainly lead to quality degradation. Opposite end as planned subsidies will allow ample time for project construction, and two years too soon, will soon come to pass. When energy prices are also cheaper. Solar energy companies need is stable, in strict accordance with the legal provisions of the policy. Instead of the current Administration to change policy.

According to industry analysts, current United Kingdom large subsidies for solar projects each year, about 170 million pounds. United Kingdom is Europe’s largest solar PV market, built capacity close to 5 billion watts. But if the Government ends subsidies in advance, will be on the United Kingdom’s large-scale installation of solar equipment market has resulted in severe impact.
