Classification of solar panels

Folding monocrystalline silicon solar panel

The photoelectric conversion efficiency of monocrystalline silicon solar panels is about 15%, up to 24%, which is high among all kinds of solar panels, but the production cost is so high that it can not be widely and widely used. Monocrystalline silicon is generally packaged with tempered glass and waterproof resin, so it is sturdy and durable, with a service life of 15 years or 25 years.

Folding 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 needs to be reduced by a lot, and its photoelectric conversion efficiency is about 12% (on July 1, 2004, Sharp, Japan, listed the world's high-efficiency polycrystalline silicon solar panels with an efficiency of 14.8%). In terms of production cost, it is cheaper than monocrystalline silicon solar panels. The materials are easy to manufacture, saving power consumption, and the total production cost is low, so it has been developed in a large number. In addition, the service life of polycrystalline silicon solar panels is shorter than that of monocrystalline silicon solar panels. In terms of performance price ratio, monocrystalline silicon solar panels are slightly better.

Folding 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 the production method of monocrystalline silicon and polycrystalline silicon solar panels. The process is greatly simplified, the silicon material consumption is small, and the power consumption is lower. Its main advantage is that it can also generate electricity in low light conditions. However, the main problem of amorphous silicon solar panels is the low photoelectric conversion efficiency, which is about 10% of the international advanced level and is not stable enough. As time goes on, its conversion efficiency will decline.

Folding multi-component solar panel

Multi compound solar panels refer to solar panels that are not made of single element semiconductor materials. There are many varieties studied in various countries, most of which have not yet been industrialized, mainly including the following:

a) Cadmium sulfide solar panel

b) Gallium arsenide solar panel

c) Copper Indium Selenium Solar Panel
