There are four types of solar panels
1.Monocrystalline silicon solar panel
At present, the photoelectric conversion efficiency of monocrystalline silicon solar cells is about 15%, and the highest is 24%, which is the highest photoelectric conversion efficiency among all types of solar cells at present, but the production cost is very high, so that it cannot be widely used. and commonly used. Since monocrystalline silicon is generally encapsulated with tempered glass and waterproof resin, it is strong and durable, with a service life of generally 15 years and a maximum of 25 years.
2. Polycrystalline silicon solar panel
The production process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, but the photoelectric conversion efficiency of polycrystalline silicon solar cells is much lower. the world's highest-efficiency polycrystalline silicon solar cells). In terms of production cost, it is cheaper than monocrystalline silicon solar cells, the material is simple to manufacture, power consumption is saved, and the total production cost is lower, so it has been greatly developed. In addition, the service life of polycrystalline silicon solar cells is also shorter than that of monocrystalline silicon solar cells. In terms of cost performance, monocrystalline silicon solar cells are slightly better.
3. Amorphous silicon solar panel
Amorphous silicon solar cell is a new type of thin-film solar cell that appeared in 1976. It is completely different from the production method of monocrystalline silicon and polycrystalline silicon solar cells. The process is greatly simplified, the consumption of silicon materials is very small, and the power consumption is lower. The advantage is that it can generate electricity even in low light conditions. However, the main problem of amorphous silicon solar cells is the low photoelectric conversion efficiency. The current international advanced level is10%, and it is not stable enough, and its conversion efficiency decays with time.
4. Multi-compound solar panels
Multi-compound solar cells refer to solar cells that are not made of single-element semiconductor materials. At present, there are many varieties of research in various countries, and most of them have not been industrialized.
