The National Energy Administration issued the "Interim Measures for the Management of Distributed Photovoltaic Power Generation Projects" on November 18, 2013 stipulated that distributed photovoltaic power generation implemented the operation model of "spontaneous use, residual power access, nearby, and power grid regulation". 2. Photovoltaic power generation: According to the principle of photocopy vod effect, the sunlight can be directly converted into electrical energy. Whether it is independent or grid -connected, the photovoltaic power generation system is mainly composed of three parts: solar panel (component), controller and inverter. They are mainly composed of electronic components and do not involve mechanical components. Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly transform the light energy into electrical energy. The key components of this technology are solar cells. After the solar cells are connected in series, the packaging protection can form a large area of ​​solar cell components, and then combined with the power controller and other components to form photovoltaic power generation devices.
