Face energy shortage today, photovoltaic power generation has become the country's future energy plan focuses on the promotion of new projects. November 1, organized by the Science and Technology Bureau of Dongguan City, Guangdong Province, convened easy special Power Co. "efficient photovoltaic inverter (100KWp-500KWp)" Project Appraisal and technological achievements in easy Bengtsson Lake Headquarters.

Appraisal committee of experts listened to the project summary of the work, technical reports, test reports, review of relevant materials and inspected the scene, after the question and discussion, the experts agreed that: research projects advanced application of the results obtained, in theory, has a strong innovative, the overall level of technology is the leading domestic.

It is understood that the "efficient photovoltaic grid connected inverter" project is funded by the Guangdong East Power Co., Ltd. and People's Liberation Army Air Force Radar Academy joint research and development. The project uses a number of high-end and network and current control technology to effectively solve the high-power photovoltaic inverter power control, anti-jamming design and other technical issues, developed a highly efficient photovoltaic inverters.

"Efficient photovoltaic off grid inverter" the MPPT efficiency, current distortion is small, the overall technology has reached advanced domestic level. Can be widely used 100KWp-500KWp voltage between the photovoltaic power generation, to fill our mid-field photovoltaic power generation technology gaps.

Currently, the project implementation process, an authorized patents, utility model patents 9, software copyright registration 4, and the other four invention patents. Results products by Dongguan, Guangdong Province Quality Supervision and Inspection Center Test (D11090074), the detected indicators meet CNCA/CTS004-2009, Q/GDW617-2011, Q/GDW618-2011 standards. Product 2 results have been applied to large-scale photovoltaic power plant construction, and achieved broad social and economic benefits.

 Trade protectionism trend seems unhealthy masterpiece. After the United States provoked the tire case of special protection, some German companies on China's trading partners around the corner. The goal is to Chinese solar companies. "Last weekend, we have reported the Ministry of Commerce and other ministries of the situation and we hope to expand some of the dialogue with German companies." Suntech Power (STP.NYSE) yesterday afternoon, a senior editor on the phone said.

He is anxious to one thing, that is virtuous counterparts to plan the German government and the European Commission to apply for Chinese-made solar modules to carry out anti-dumping investigations. Currently 90% of our exports overseas solar cells, has emerged as the world's largest manufacturing base. And China, once the world's largest manufacturer of solar photovoltaic exporter German government behavior and to determine the existence of anti-dumping sanctions against Chinese companies will be very large.

Ministry of Commerce website quoted the German "Handelsblatt" the source said, the German solar manufacturer Conergy Company wishes to join forces with other counterparts, the German government and the European Commission to apply for Chinese-made solar cells anti-dumping investigation Conergy CEO Ammer (Dieter Ammer) said, "(Chinese solar modules) prices are dumping the edge", according to the current price level, Chinese manufacturers can not be profitable without state support. According to "China Entrepreneur" website news, the company spokesman Le Huosi right to edit the telephone, said: "The EU is necessary to come out (on Chinese exports of solar modules) to levy punitive tariffs."

But the chairman of the German solar Photovoltaic Panels Economic Association yesterday told the editor Carsten Koernig, taken note of the media on the Chinese solar export price advantage reactions reports and relevant enterprises, is currently in information collection and verification stage, if confirmed by Chinese export price advantage after excessive and with national policy-related subsidies, from the perspective of industry associations will be considered for further investigation and even filed anti-dumping complaint.

Carsten Koernig also said that because of the verification work is at an early stage, when they can not be estimated yet concluded; conclusions too early to make any forecasts. The Chinese government this year were launched the "Solar Roofs Plan" ("on accelerating the implementation of solar PV building applications opinions"), "Golden Sun Project" ("Golden Sun Demonstration Project financial assistance fund management Interim Measures"), intends to domestic solar power plants, photovoltaic building investors subsidies.

 U.S. solar companies First Solar9 August said it plans to build in China, the world's largest solar power plant. According to the Chinese government signed a memorandum of understanding, First Solar will be in China's Ordos City, Inner Mongolia Autonomous Region to build a 2GW of power, enough to provide electricity to about 300 million households.

First Solar will begin construction in June 2010 the first phase of 30 MW demonstration project, the second and third phase of the project will be 100 MW and 870 MW in 2014. Last one of 1000 MW will be built by the year 2019.

Investment Advisor in the new energy industry's chief researcher Jiang Qian pointed out that, in the forthcoming "New Energy Industry Promotion Plan", the country might be planning PV 2020 from the previous 1.6GW (gigawatt) to 20GW, the original plan 12.5 times, which is already the next decade China's largest PV market capacity. The First Solar's 2GW power plant to be built by 2019 can be completed.

This means that only First Solar  wind grid tie inverter  a company's future will occupy the entire Chinese PV market 1/10 of the share, but also includes planning target of 20GW end of 2008, the country has installed capacity of 140MW PV systems.

Jiang Qian suggested that not only First Solar, the future certainly will be other foreign enterprises to enter the Chinese PV market, which will also exacerbate the degree of competition in the market, and for domestic PV manufacturers, in order to compete with international giants occupy advantages, I'm afraid there is more work to be done. This is not only crucial for the development of enterprises, but also to the entire industry's healthy development process.

As the world's largest manufacturer of thin-film solar, First Photovoltaic Panels momentum of rapid development in the past year. Investment Advisor in the latest release of "2009-2012 China thin film solar cell industry investment analysis and forecast report" shows that in 2009 the overall downturn in the first half of the global PV market situation under, First Solar's revenue still up $ 944.1 million, an increase of 103.5%. Again showed strong momentum of development.

By Jiangsu Wuxi's "PV modules photoelectric conversion rate test method", "solar grade silicon Determination of trace elements - Glow discharge mass spectrometers Law" two local standards currently approved by the Jiangsu Provincial Quality and Technical Supervision, have been through the project, the preparation phase into the draft standard.

It is understood that the photoelectric conversion efficiency of solar photovoltaic modules solar photovoltaic products reflect an important indicator of quality, but also the policy of state support for solar photovoltaic important basis. Industry experts said that although China's largest producer of crystalline silicon solar cells country, but photovoltaic PV modules is no uniform standard for determination of the long-term.

In March, the Ministry of Finance, Ministry of Construction, respectively, issued the "solar PV building applications for financial assistance fund management Interim Measures" and "solar photovoltaic building demonstration project reporting guidelines," which called for financial fixed subsidy rate for solar photovoltaic power generation products need reached the advanced level, including monocrystalline silicon modules conversion efficiency of more than 16 per cent more than fourteen percent of polysilicon, amorphous silicon over six per cent.

National Solar Photovoltaic Products Quality Supervision and Inspection Center (Wuxi City Product Quality Supervision and Inspection Institute) established in accordance with the above provisions related to local standards, the staff said, the standard will be unified component conversion efficiency evaluation, promotion of solar cell production and packaging process level, promote the overall development of photovoltaic industry in Jiangsu.

Data show that in 2008 Chinese crystalline silicon solar photovoltaic  http://www.sungoldpower.co.uk/ products reach two thousand five hundred seventy-three MW, accounting for 25 percent of global output around. In China, Jiangsu solar photovoltaic products production reached one thousand five hundred fifty-seven MW, accounting for about 60 percent of national output.

 Siemens West Chicago, Illinois, has completed the upgrade of the plant to begin production of photovoltaic inverters. Siemens has invested about $ 10 million to the two plants into this upgrade, which one will be used to support the rapid growth of the U.S. solar power market.

     Currently, Siemens is located in West Chicago is producing SINVERT PVS PV off grid inverter for the American Southwest 20ME use solar power plants.
