What’s the Differences Between Monocrystalline solar panel and Polycrystalline solar panel ?

Solar street lamps usually use two kinds of solar panels, Monocrystalline solar panels, and polycrystalline solar panels. Silicon is the raw material for making solar cells, but it is not easy to extract it. Therefore, while producing monocrystalline solar cells, people also studied polycrystalline solar cells. So how do distinguish monocrystalline solar panels and polycrystalline solar panel correctly?

Firstly: Appearance differences

Looking from the appearance, the four corners of the monocrystalline solar cell are circular, and the surface is not patterned; while the four corners of the polycrystalline cell are square, and the surface is like an ice flower.

Secondly: Usage differences

For users, there is no big difference between monocrystalline solar panels and polycrystalline solar panels. Both of their life and stability are very good. Although the average conversion efficiency of monocrystalline silicon panels is about 1% higher than that of polycrystalline silicon panels, monocrystalline silicon panels can only be made into quasi-square (all sides are circular arcs), some areas of solar panels will not be filled when they are made up; while polycrystalline silicon is square, so there is no such a problem, their advantages, and disadvantages.
