According to the type of battery cells, they can be divided into three types: monocrystalline, polycrystalline and amorphous. Most of the current factory production is polycrystalline and less amorphous monocrystalline
Depending on the cells included in. the panel The number of cells mainly includes: 5612p, 5612M, 6610P, 6612P
Note: 5612M
5: Cell size
6: Number of channels of cells
12: The number of cells in a single chain
P (polycrystalline), M (monocrystalline)
Most pure blacks you see are: monocrystalline
Dark blue is mostly: polycrystalline
The "flower" the poster mentions is only found in polycrystalline. The polycrystalline is composed of several single crystals and when the single crystal is. crystallized, there will be limitations due to different conditions. After wire cutting, you will see irregular patterns, commonement called “flowers.” In fact, a flower is a single crystal, so a conversion from a single crystal The effectiveness of large flowers. is higher than that of small flowers.
What is the difference between monocrystalline and polycrystalline solar panels?
Which is better, monocrystalline solar panels or polycrystalline solar panels?
Monocrystalline solar panels are slightly better than polycrystalline solar panels in terms of energy efficiency conversion, power output and stability.
However, the cost of polycrystalline solar panels is lower and is suitable for large-scale power generation projects.
Overall, monocrystalline solar panels are more suitable for scenarios with higher performance requirements, while polycrystalline solar panels are more suitable for scenarios where economy is a priority.
1. Difference in appearance
From the appearance, the four corners of the single crystal silicon cells are arc-shaped, and there is no pattern on the surface. The four corners of the polycrystalline silicon cells are square, and the surface has a pattern similar to ice flowers.
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
The energy consumed in the manufacturing process of polycrystalline silicon solar cells is approx.n 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%.
