Solar panels are assembled assemblies of multiple solar cells and are a core part of solar power systems and the most important part of solar power systems. Today, I will tell you about the types of solar panels.
1. Monocrystalline silicon solar panel
The photoelectric conversion efficiency of monocrystalline silicon solar panels is about 15%, up to 24%. This is a high photoelectric conversion efficiency of various solar panels, but the production cost is too large to be widely used. And commonly used. Since monocrystalline silicon is usually packaged in tempered glass and waterproof resin, it is durable and has a service life of 15 years and a maximum of 25 years.
2. Polycrystalline solar panels
The manufacturing 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 is much lower, and its photoelectric conversion efficiency is about 12% (July 1, 2004, performance). The proportion of Japan is 14.8%. Very effective polycrystalline silicon solar panels in the world). In terms of production cost, it is cheaper than monocrystalline silicon solar panels, simple in material manufacturing, power saving, and low total production cost, so it has been greatly developed. In addition, the life of polycrystalline silicon solar panels is also shorter than the lifetime of monocrystalline silicon solar panels. In terms of performance and price ratio, monocrystalline silicon solar panels are slightly better.
3. Amorphous silicon solar panel
Amorphous silicon solar panels are new thin film solar panels that emerged in 1976. They are completely different from monocrystalline and polycrystalline solar panels. This process is greatly simplified, with less silicon material consumption and lower power consumption. 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, the international advanced level is about 10%, and it is not stable enough. As time goes by, its conversion efficiency will decrease.
4. Multi-component solar panels
A multi-component solar panel refers to a solar panel that is not made of a single component semiconductor material. There are many kinds of research in various countries, most of which have not yet been industrialized, mainly including cadmium sulfide solar panels, gallium arsenide solar panels and copper indium selenide solar panels.
