The main material of photovoltaic solar panels is 'silicon', which is a device that absorbs sunlight and converts solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. It is an energy-saving and environmentally-friendly green product. The application fields of photovoltaic power generation are becoming wider and wider, from household photovoltaic to industrial and commercial distributed, from the installation of photovoltaic power stations on the roof and free land to the birth of various photovoltaic small objects. Nowadays, photovoltaic power generation is used in hospitals, schools, homes, transportation, parking lots, tower base stations, gas stations, logistics and warehousing, lighting power supplies, industrial plants, etc.
