1. Monocrystalline silicon solar panels
The photoelectric conversion efficiency of monocrystalline silicon solar panels is about 15%, and the highest is 24%. This is the highest photoelectric conversion efficiency of all types of solar panels, but the production cost is so large that it cannot be widely and widely used. To use. 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.
2. Folding polysilicon solar panels
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, and its photoelectric conversion efficiency is about 12%. In terms of production cost, it is cheaper than monocrystalline silicon solar panel, the material is simple to manufacture, it saves electricity 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.
3. Folding amorphous silicon solar panels
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 decreases.
4. Folding multiple compound solar panels
Multi-compound solar panels refer to solar panels that are not made of a single element semiconductor material. There are many kinds of researches in various countries, most of which have not been industrialized, mainly as follows:
a) cadmium sulfide solar panel, b) gallium arsenide solar panel, c) copper indium selenium solar panel.
