Technical Field

Background

The monocrystalline photovoltaic module refers to a module taking monocrystalline silicon as a solar cell basic material. The solar photovoltaic module is characterized by high conversion efficiency (usually 15-25%), large volume and high price, and the single crystal photovoltaic module and the polycrystalline photovoltaic module are collectively called as a photovoltaic module, and the photovoltaic module is also called a solar panel or a photovoltaic panel. For large photovoltaic power stations, the cost of the polysilicon components is lower, the cost performance is higher, and the single crystal solar panel is an assembly formed by assembling a plurality of single crystal solar cells on a panel in a certain mode. The photoelectric conversion efficiency of the single crystal silicon solar cell is about 15% and up to 24% at the highest, which is the highest photoelectric conversion efficiency among all kinds of solar cells, but the manufacturing cost is so great that it has not been widely and universally used in large quantities. Because monocrystalline silicon is generally packaged by toughened glass and waterproof resin, the monocrystalline silicon is firm and durable, and the service life of the monocrystalline silicon can reach 15 years, and can reach 25 years at most. The solar energy charging device is mainly used for producing and using high-quality solar energy lamps, and the charging efficiency is higher than that of a polycrystalline solar panel.
