On April 10, the national photovoltaic and energy storage demonstration experimental platform (Daqing base) approved by the state energy administration broke the ground, marking the first "state-owned brand" new energy outdoor demonstration experimental platform settled in Daqing and officially entered the substantive construction stage.

　　The development and utilization of solar energy and energy storage are important measures to achieve carbon peak and carbon neutralization. In recent years, China's photovoltaic and energy storage technology has made great progress, and the laboratory research level of key equipment such as photovoltaic modules and inverters has been continuously improved. However, systematic research on outdoor actual operation is still lacking, which leads to the fact that the actual operation performance of many completed photovoltaic power generation systems has not been scientifically and effectively evaluated.

　　"No matter how good the effect is in the laboratory, the actual effect of the product still needs to be seen in the actual use. Only by doing a good outdoor empirical research, can we grasp the real situation of photovoltaic products in outdoor operation." Pang Xiulan, deputy general manager of national power investment photovoltaic industry technology innovation center, explained that outdoor lighting, soil and even surface water pH will affect the performance of photovoltaic products. Outdoor empirical research under real operating conditions can record in detail the real attenuation rate, hidden crack and other technical parameters of photovoltaic products that cannot be obtained in the laboratory.

　　Throughout the world, there is no mature photovoltaic and energy storage empirical experimental platform, and the construction of this kind of platform is still in the exploratory stage. Pang Xiulan believes that the construction of the national photovoltaic and energy storage empirical experimental platform (Daqing base) is of great significance. "The empirical experimental platform can obtain valuable measured data, help enterprises improve product performance, improve manufacturing quality, and make products more suitable for actual operating conditions."

　　"From a more macro perspective, the outdoor empirical research on key equipment, products and systems of photovoltaic and energy storage can provide a public service platform for the practice of the whole industry, provide data support for theoretical research and technological innovation, provide scientific basis for the state to formulate industrial policies and technical standards, and contribute Chinese wisdom, Chinese solutions and Chinese standards to the development of global new energy industry Yes Wang Dapeng, deputy director of the new and renewable energy department of the national energy administration, said.

　　The relevant person in charge of Daqing municipal government said that the platform can also bring opportunities for local development, driving the photovoltaic industry chain, supply chain innovation chain to take root in Daqing, and promoting the "Centennial Oilfield" to high-quality development.

　　The reporter learned that the Yellow River Company of state power investment group, the construction and management unit of the platform, is the largest photovoltaic power generation operator in the world at present, and also the only energy central enterprise with photovoltaic demonstration base construction experience in China. Xie Xiaoping, Secretary of the Party committee and chairman of the Yellow River company, revealed that during the "14th five year plan" period, the platform plans to invest about 6 billion yuan and plan to arrange about 640 empirical experimental schemes.

　　Shen Youguo, deputy chief engineer of the Yellow River company and general manager of the new energy construction branch, said that after the completion of the platform, it has three functions: demonstration, experiment and detection. According to the construction and operation of the platform, the following functions can be expanded, such as certification.
