Solar panel classification

Monocrystalline silicon solar panels

Photovoltaic conversion efficiency of monocrystalline silicon solar panels is about 15%, the highest reached 24%, which is all kinds of solar panels in the photoelectric conversion efficiency

The rate is highest but the production cost is so great that it can not yet be widely used and widely used. As the single crystal silicon glass and waterproof resin are generally used for packaging, so its ruggedness, the service life of up to 15 years, up to 25 years.

Polycrystalline solar panels

The production process of polycrystalline silicon solar panel is similar to that of monocrystalline silicon solar panel, but the photoelectric conversion efficiency of polycrystalline silicon solar panel is much lower,

Photoelectric conversion efficiency of about 12% (July 1, 2004 Japan's Sharp listing efficiency of 14.8% of the world's most efficient polycrystalline silicon solar panels). Speaking from the production costs, monocrystalline silicon solar panels to be cheaper, easier to manufacture materials, saving power consumption, the total cost of production is lower, so a lot of development. In addition, the service life of polycrystalline silicon solar panels is also shorter than monocrystalline solar panels. In terms of cost performance, monocrystalline silicon solar panels also slightly better.

Amorphous silicon solar panels

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

Multi-compound solar panels

Poly-compound solar panels refer to solar panels that are not made from single-element semiconductor materials. There are a great variety of studies in various countries, most of which have not yet been industrialized. The main ones are as follows:

a) Sulfated solar panels

b) Gallium arsenide solar panels

c) copper indium selenium solar panels
