1. Difference in appearance
From the appearance, the four corners of monocrystalline silicon cells are arc-shaped and have no patterns on the surface, while the four corners of monocrystalline silicon cells are polycrystalline silicon are; It has square corners and a pattern similar to ice flowers on the surface.
2. Usage Differences
The average conversion efficiency of monocrystalline silicon cells is approximately 1% higher than that of polycrystalline silicon cells. However, monocrystalline silicon cells can only be made into quasi-cells. -square shapes (all four sides are arc-shaped), so when forming a solar panel, part of the area will not be filled. Polysilicon is square, so there is no such problem;
3. Different manufacturing processes
Energy consumed in the manufacturing process of polycrista silicon solar cellsllin is about 30% lower than monocrystalline silicon solar cells. Therefore, polycrystalline silicon solar cells. represent the total global production of solar cells. The share is large and the manufacturing cost is lower than that of monocrystalline silicon cells.
4. Different dosages
The application of polycrystalline silicon in power plants is much higher than that of single crystal silicon, with single crystal silicon accounting for 30% and polycrystalline silicon accounting for 70%.

How to distinguish whether a solar panel is monocrystalline or polycrystalline?
Okay, polysilicon. 1. Monocrystalline Silicon Polycrystalline silicon is a raw material used to make solar panels. 2. SilicIum is an extremely abundant element on earth. It is present almost everywhere and can be considered inexhaustible. There is no shortage of raw materials for manufacturing silicon-based solar cells. 3. The speed of polycrystalline silicon solar panels is generally two to three times that of monocrystalline silicon, and the voltage should be stable. 4. The manufacturing process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, and the photoelectric conversion efficiency is about 12%, which is slightly lower than that of monocrystalline silicon solar cells. . However, the manufacturing of the material is simple and convenient, consumes less energy, and the total production cost is low, so it has been greatly developed.
Single crystal has a high conversion efficiency and is expensive; polycrystalline has a low convers efficiencyion and is cheap.
There are many polycrystals in the domestic market, or they are all polycrystals.
The Japanese market is very popular recently, but Japan's requirements are very high and they are all monocrystalline. People's idea of Japan is to do your best and do it right the first time. It has very high requirements for mitigation effectiveness, and we need to learn from that at home.
Are polycrystalline or monocrystalline solar panels better?
If you look closely, you can usually tell by visual inspection\x0d\ Monocrystalline solar panels: no pattern, blue color dark, almost black after encapsulation\x0d\Polycrystalline solar panels: Patterned, multi-colored polycrystalline and less colorful polycrystalline, like patterns of snowflake crystals on iron sheets, light blue\x0d\Panels samorphous lolars: Most of them are glass, brown and brown< /p>
