In order to promote the technical progress and industrial upgrading of photovoltaic power generation and promote the transformation of resource-based cities into energy development modes, the National Energy Administration recently approved the construction of a national advanced photovoltaic demonstration base for coal mining subsidence in Datong, Shanxi Province. According to reports, this is China's first large-scale photovoltaic power station base to promote the application of advanced technology photovoltaic products. China's first advanced technology demonstration base in Shanxi Datong Datong This is what reporters learned from the launch of the state-of-the-art photovoltaic demonstration base construction in Datong coal mining subsidence area held in Beijing on the 6th. According to the "Opinions on Promoting the Application and Upgrading of Advanced Photovoltaic Technology Products" previously promulgated by the National Energy Administration, the Ministry of Industry and Information Technology and the CNCA, China will increase market access standards for PV products and implement the "Top Runner" program. Yiyue Chun, vice president of China Water Power Planning and Design Institute, an agent unit of demonstration base, introduced at the start-up meeting. The demonstration base will have a construction scale of 1 million kilowatts in 2015. Base aims to scale the application of advanced technology photovoltaic products, create "new demonstration of photovoltaic technology, leading technology practice, advanced technology gathering place" to promote photovoltaic technology and industrial upgrading. At the same time, the demonstration base will be the development of photovoltaic power generation, new energy and coal mining subsidence combined to explore the mining subsidence area for ecological restoration, and thus promote resource-based energy transformation of cities are of great significance. According to reports, all photovoltaic power station projects at the demonstration base will purchase PV products that meet the advanced technical indicators of "Top Runners". For example, the photoelectric conversion efficiency of polysilicon and monocrystalline silicon photovoltaic modules should reach 16.5% and 17%, respectively. And thin film photovoltaic modules photoelectric conversion efficiency should reach 30% and 12% respectively, all products should pass the testing and certification of third-party testing certification body certification. It is understood that the demonstration base of project investment and owner selection commissioned by the Datong Municipal People's Government entrusted Hydropower Planning and Design Institute in accordance with the principles of openness, fairness and fairness through competition, all projects strive to be completed before the end of this year.
