Photovoltaic, or photovoltaic power generation system, is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar Radiant energy into electrical energy. The energy of photovoltaic power generation systems comes from inexhaustible solar energy, which is a clean, safe, and renewable energy source. The photovoltaic power generation process does not pollute the environment or damage the ecology.

Photovoltaic power generation systems are divided into independent photovoltaic systems and grid connected photovoltaic systems. The photovoltaic power generation system is composed of solar cell arrays, battery packs, charge and discharge controllers, inverters, AC distribution cabinets, solar tracking control systems, and other equipment.
