Description

Polycrystalline silicon solar panels, which are mainly used on the market, are aggregate structures containing a large amount of single crystal particles. It is made of polycrystalline block material with a resistance of 100~300Ω. It is made into a square shape for cutting into solar panels. The photoelectric conversion rate of polycrystalline silicon solar panels is about 12%, which is slightly lower than that of monocrystalline silicon solar panels, but the manufacturing is simple, energy saving, and the total manufacturing cost is low. Therefore, it is widely used. With the development of technology and technology, the current photoelectric conversion rate can reach about 18%.

Advantage

1. The process for manufacturing polysilicon is simpler and less expensive. The amount of waste silicon is small compared to single crystal.

2. The heat resistance of polycrystalline solar panels is often slightly lower than that of monocrystalline solar panels. Polycrystalline solar panels tend to have a higher temperature coefficient than solar modules fabricated using single cells. This means that the output will decrease as the heat of this type of battery increases.
