Concentrated Photovoltaic (CPV) is currently the most efficient photovoltaic power generation technology with a battery efficiency of 40%, component efficiency of 28%, and system efficiency of 25%. Compared with the 15% efficiency of common crystalline silicon flat-panel solar cells, concentrating photovoltaic is the first solar photovoltaic technology that can reduce the cost of photovoltaic power generation to the cost of coal-fired electricity.
High-concentration photovoltaic power generation technology has only started in China, and concentrating photovoltaics in Europe and the United States has gradually become a mainstream technology. Especially since 2010, high-concentration photovoltaic has obtained several photovoltaic power plant projects of 10MW and above. Domestic listed companies such as Sanan Optoelectronics (600703) have also begun to get involved in concentrating photovoltaic technology.
Wu Dacheng, deputy director of the Photovoltaic Professional Committee of China Renewable Energy Society, said that CPV technology has an important position in the development of photovoltaics. There is still a gap between China's research and application promotion in this field. In recent years, the emphasis on this field has been improved. Field research has been included in this year's 863 program, and China has initially formed a certain scale in the localization of CPV technology.
The largest grid-connected concentrating photovoltaic power station in China was completed.
A 200KW high-concentration photovoltaic power plant was built on January 15th. It is the largest high-concentration photovoltaic power station that has been put into operation in China. The owner of the demonstration power station is Qingdao Harbin Solar Energy Co., Ltd., and the concentrating photovoltaic technology system used by Shanghai Juheng Solar Energy Co., Ltd. is provided. It is understood that Qingdao Harbin Solar plans to build a 7 megawatt high-concentration photovoltaic power station in December 2011.
