Description

Technical Field

[0002] Photovoltaic system is a system that uses solar energy to generate electricity. It is mainly composed of photovoltaic modules, inverters, grid-connected cabinets and other electrical equipment. Photovoltaic modules are the core part of the photovoltaic system. They are made up of a certain number of solar cells connected in series or in parallel and then packaged and protected. The power generation principle of photovoltaic modules is to use the photovoltaic effect of solar cells to directly convert light energy into electrical energy. The power generation efficiency, stability and life of photovoltaic modules directly affect the performance of the entire photovoltaic system. The working principle of the photovoltaic system is based on the photovoltaic effect, that is, when light shines on solar cells, photons with sufficient energy can excite electrons from covalent bonds in semiconductor materials to form electron-hole pairs. Before these electrons and holes recombine, they are separated from each other by the electric field of space charges to form current. By connecting photovoltaic modules in series or in parallel, enough electricity can be generated for users to use or to be incorporated into the power grid.
