polycrystalline vs monocrystalline solar panels

1. The difference between polycrystalline and monocrystalline: the monocrystalline panel is black, and the polycrystalline panel is blue or colored.

2. Disadvantages: Compared with the polycrystalline board of the same power, the area of the polycrystalline board is slightly larger than that of the monocrystalline board. The same 50W polycrystalline board will be 1.1 times larger than the single crystal board.

3. Advantages: The polycrystalline plate receives light in multiple directions and has good directionality. In the actual test, assuming that one hand is used to block the sunlight and leave a shadow on the surface of the solar power generation panel, the power generation current of the polycrystalline panel is not significantly reduced, but the power generation current of the single crystal panel is significantly reduced, which is the advantage of the polycrystalline panel.
