How to Identify Monocrystalline and Polycrystalline Solar Panels

Solar panels are divided into monocrystalline, polycrystalline and amorphous silicon. Currently, most solar panels use monocrystalline and polycrystalline materials. So, how to identify monocrystalline and polycrystalline solar panels? What are the characteristics of monocrystalline and polycrystalline solar panels?

1. Identify from the materials of monocrystalline and polycrystalline solar panels

Monocrystalline and polycrystalline solar panels are two different materials. Polysilicon is a chemical term, commonly known as glass. High-purity polycrystalline material is high-purity glass. Monocrystalline silicon is the raw material for solar photovoltaic cells and semiconductor chips. The raw materials of monocrystalline silicon are rare and the production process is complicated. Therefore, the production rate is low and the price is very high.

2. Identify from the processing technology of monocrystalline and polycrystalline solar panels

In simple terms, the difference between monocrystalline and polycrystalline solar panels is the arrangement of their atomic structure. Monocrystalline is arranged in order while polycrystalline is arranged in disorder. This is mainly determined by their processing technology. Polycrystalline solar panels for sale is produced by the casting method, which means that the silicon material is directly poured into a pot to melt and mold.

The monocrystalline adopts the Siemens process to improve the Czochralski method, which is a process of atomic restructuring. The surface of monocrystalline silicon looks the same, and the surface of the polycrystalline silicon looks like there is a lot of broken shining glass.
