Rack mounted solar panel – does the solar panel have radiation

“< H2 > what is a solar panel

Solar panel is a device that converts solar radiation energy into electric energy directly or indirectly through photoelectric effect or photochemical effect by absorbing sunlight. The main material of most solar panels is “”Silicon””, but its widespread use has certain limitations due to its high manufacturing cost. Compared with ordinary batteries and rechargeable batteries, solar cells are more energy-saving and environment-friendly green products

What are the types of solar panels

Types of solar panels:

1. Monocrystalline silicon solar cell:

At present, the photoelectric conversion efficiency of monocrystalline silicon solar cells is about 15%, and the highest is 24%, which is the highest among all kinds of solar cells, but the manufacturing cost is so high that it can not be widely and widely used

2. Polysilicon solar cells:

The manufacturing 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, and its photoelectric conversion efficiency is about 12% (Japan sharp listed the world’s most efficient polycrystalline silicon solar cells with an efficiency of 14.8% on July 1, 2004)

3. Amorphous silicon solar cells:

Amorphous silicon solar cell is a new type of thin-film solar cell appeared in 1976. It is completely different from the manufacturing method of monocrystalline silicon and polycrystalline silicon solar cells. The process is greatly simplified, the consumption of silicon materials is small, and the power consumption is lower. Its main advantage is that it can generate electricity under weak light conditions

4. Multicomponent compound solar cells:

Multicomponent compound solar cells refer to solar cells that are not made of single element semiconductor materials. At present, there are many kinds of research in various countries, and most of them have not been industrialized

What kinds of solar panels can be divided into

The solar panels of solar power generation system are mainly divided into the following types? (1) Polycrystalline silicon solar cell the manufacturing process of polycrystalline silicon solar cell is similar to that of monocrystalline silicon solar cell, but the photoelectric conversion efficiency of polycrystalline silicon solar cell is much lower, and its photoelectric conversion efficiency is about 12%. In terms of production cost, it is cheaper than monocrystalline silicon solar cells. The materials are easy to manufacture, save power consumption, and the total production cost is low. Therefore, it has been greatly developed. In addition, the service life of polycrystalline silicon solar cells in Sichuan is also shorter than that of monocrystalline silicon solar cells. In terms of performance price ratio, monocrystalline silicon solar cells are slightly better. (2) Amorphous silicon solar cell amorphous silicon Sichuan solar cell is a new type of thin-film solar cell appeared in 1976. It is completely different from the manufacturing method of monocrystalline silicon and polycrystalline silicon solar cells. The process is greatly simplified, the consumption of silicon materials is small, and the power consumption is lower. Its main advantage is that it can generate electricity under weak light conditions. However, the main problem of amorphous silicon solar cells is the low photoelectric conversion efficiency, which is about 10% of the international advanced level, and is not stable enough. With the extension of time, its conversion efficiency decreases. (3) Monocrystalline silicon solar cell the photoelectric conversion efficiency of monocrystalline silicon solar cell is about 15%, and the highest is 24%, which is the highest among all kinds of solar cells, but the manufacturing cost is so high that it can not be widely used. Because monocrystalline silicon is generally encapsulated with toughened glass and waterproof resin, it is durable and has a service life of 15 years and up to 25 years. (4) Multicomponent compound solar cell multicomponent compound solar cell best solar racking system refers to a solar cell that is not made of a single element semiconductor material. There are many kinds of research in various countries, and most of them have not been industrialized. Semiconductor materials with gradient band gap (energy level difference between conduction band and valence band) can expand the range of solar absorption spectrum and improve the photoelectric conversion efficiency. Based on it, thin-film solar cells with significantly higher photoelectric conversion efficiency than silicon thin-film solar cells can be designed
