Solar photovoltaic power generation system is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electric energy. It has two operating modes: independent and connected to the network. operation. Independently operated photovoltaic power generation systems require batteries as energy storage devices. They are mainly used in remote areas without a power grid and in areas with sparse populations. The cost of the entire system is very high. In areas with public power grids, photovoltaic power generation systems are connected to the power grid and operate on the grid, eliminating the need for batteries. This can not only significantly reduce costs, but also have ae higher power generation efficiency and better environmental performance.
In recent years, photovoltaic energy production has developed rapidly on an international scale. More than 10 megawatt-level photovoltaic power generation systems and 6 megawatt-level connected photovoltaic power plants have been built around the world. It is estimated that in the near future, solar photovoltaic power generation will occupy an important place in global energy consumption, not only replacing some conventional energy sources, but also becoming the main source of global energy supply .
