1. Appearance difference

From the appearance, the four corners of the monocrystalline panel are arc-shaped and there are no patterns on the surface. Monocrystalline panels look the same on the surface. The four corners of the polycrystalline panel are square and have patterns. There are polycrystalline multi-color and polycrystalline less-color, like the snowflake crystal pattern on the snowflake iron sheet, which is light blue. The surface of the polycrystalline panel looks like there are a lot of broken glass inside, shining.

2. Manufacturing process difference

The difference between monocrystalline silicon and polycrystalline silicon lies in their atomic structure arrangement. Monocrystalline is orderly arranged, while polycrystalline is disordered. This is mainly determined by their processing technology. Polycrystalline is mostly produced by casting method, that is, directly pouring silicon material into the crucible to melt and shape, while monocrystalline is improved by Siemens method and pulled directly. The direct pulling process is a process of atomic structure reorganization.

The energy consumed in the manufacturing process of polycrystalline solar panels is about 30% less than that of monocrystalline solar panels. Therefore, polycrystalline solar panels account for a large share of the total global solar panel production, and the manufacturing cost is also lower than that of monocrystalline panels.
