Solar panel classification

Monocrystalline solar panels

The photoelectric conversion efficiency of monocrystalline silicon solar panels is about 15%, and the highest is 24%. This is the photoelectric conversion efficiency of all types of solar panels.

The most efficient, but the production cost is so great that it cannot be widely and widely used. Since monocrystalline silicon is generally encapsulated with toughened glass and waterproof resin, it is durable and has a service life of up to 15 years, and up to 25 years.

Polycrystalline silicon 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 has to be reduced a lot.
Polycrystalline solar panels
The photoelectric conversion efficiency is about 12% (on July 1, 2004, Sharp listed the world's highest efficiency polysilicon solar panel with an efficiency of 14.8%). In terms of production cost, it is cheaper than monocrystalline silicon solar panel, the material is simple to manufacture, it saves power consumption, and the total production cost is lower, so it has been developed in a large amount. 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 type of 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 low, and the power consumption is lower. The main advantage is that it can generate electricity 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.
