Background technique

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 electrical energy. There are two modes of independent operation and grid-connected operation. Independently operating photovoltaic power generation systems require batteries as energy storage devices, which are mainly used in remote areas without power grids and scattered population areas, and the cost of the entire system is very high. The elimination of batteries can not only greatly reduce the cost, but also have higher power generation efficiency and better environmental performance. Photovoltaic power generation equipment is generally installed in remote areas, where the environment is relatively harsh, and the existing photovoltaic panels have less external protection measures.
