What are the types of solar panels?


Monocrystalline solar panel

The photoelectric conversion efficiency of monocrystalline silicon solar panels is about 15%, and the highest reaches 24%. ground use. Because monocrystalline silicon is generally encapsulated with tempered glass and waterproof resin, it is durable and its service life can generally reach 15 years, and the maximum can reach 25 years.

Polysilicon Solar Panel

The production process of polycrystalline silicon solar panels is similar to that of monocrystalline silicon solar panels, but the photoelectric conversion efficiency of polycrystalline silicon solar panels is much lower. The world's highest efficiency polysilicon solar panels). In terms of production cost, it is cheaper than monocrystalline silicon solar panels, the material is easy to manufacture, saves power consumption, and the total production cost is low, so it has been greatly developed. In addition, the service life of polycrystalline silicon solar panels is shorter than that of monocrystalline silicon solar panels. In terms of cost performance, monocrystalline silicon solar panels are slightly better.

Amorphous silicon solar panel

Amorphous silicon solar panel is a new thin-film solar panel that appeared in 1976. It is completely different from monocrystalline silicon and polycrystalline silicon solar panels. The process is greatly simplified, the silicon material consumption is very small, and the power consumption is lower. Its The main advantage is that it can generate electricity even in low light conditions. However, the main problem of amorphous silicon solar panels is that the photoelectric conversion efficiency is low, the international advanced level is about 10%, and it is not stable enough. As time goes by, its conversion efficiency decays.

Multi-component solar panel

A multi-component solar panel refers to a solar panel that is not made of a single element semiconductor material. There are many varieties studied in various countries, most of which have not yet been industrialized, and mainly include the following:

a) CdS solar panels

b) GaAs solar panels

c) Copper Indium Selenium Solar Panel
