A photovoltaic generation system, abbreviated as photovoltaic, refers to a power generation system that utilizes the photovoltaic effect of photovoltaic cells to directly convert solar radiation energy into electrical energy. It consists of solar cell modules (arrays), controllers, energy storage batteries (packs), DC/AC inverters, etc. It can be used for domestic power supply in remote areas without electricity, and is also widely used in transportation, communication, petroleum, marine, meteorology, aerospace, and other fields.
