PERC Half Cell Bifacial 500 Watts All Black Solar Panel Monocrystalline
What is the Difference Between Monocrystalline and Polycrystalline Solar Panels?
The main difference between the two technologies is in the crystal purity of the panel cells. Monocrystalline solar panels have solar cells made from a single crystal of silicon while polycrystalline solar panels have solar cells made from several fragments of silicon melted together. The crystalline purity of the cells of monocrystalline solar panels is therefore much higher than that of polycrystalline solar panels.
The image below shows you how to distinguish the two different types of solar panels. Monocrystalline cells are black and octagonal while polycrystalline cells are dark blue and squared.
