Types of solar panels

(1) Single crystal silicon solar panel

The color of the single crystal solar panel is mostly black or dark or dark, and the color after packaging is close to black. At present, the photoelectric conversion efficiency of single -crystalline silicon solar cells is about 18%, and the high is 24%. This is the high photoelectric conversion efficiency in all types of solar cells at present, but the production cost is very large, so that it cannot be extensively extensively extensively extensively. And universal use. Because single crystal silicon is generally encapsulated with tempered glass and waterproof resin, it is solid and durable. The service life can generally reach 15 years, up to 25 years.
(2) Polycrystalline silicon solar panel

The polycrystalline solar panel has patterns, colorful and colorful, light blue. The production process of polysilicon solar batteries is similar to that of single crystal silicon solar batteries, but the photoelectric conversion efficiency of polysilicon solar cells is reduced a lot, and its photoelectric conversion efficiency is about 12%. In terms of production costs, it is cheaper than single crystal silicon solar cells. It is easy to manufacture, save power, and has a low total production cost, so it has developed a lot of development. In addition, the service life of polycrystalline solar batteries is also shorter than single crystal silicon solar cells. In terms of performance price ratio, single crystal silicon solar cells are still slightly better.
(3) Averse crystal silicon solar cell

Most amorphous solar panels are glass and brown tea. A amorphous silicon solar battery is a new type of film -type solar cell that appeared in 1976. It is completely different from the production method of single crystal silicon and polycrystalline silicon solar batteries. The process is greatly simplified. The advantage is that it can also be generated in the weak light conditions. However, the main problem of the existence of amorphous silicon solar batteries is related to the season, and the photovoltaic conversion efficiency like autumn and winter seasons is low. At present, the international advanced level is about 10%, and it is not stable enough. Over time, its conversion efficiency is attenuated.
