A monocrystalline solar panel is a solar panel that includes monocrystalline solar cells. These cells consist of a cylindrical silicon ingot, which was developed like a semiconductor from a high-purity silicon single crystal. The cylindrical ingot is cut into cells in wafers. When sunlight falls on the monocrystalline solar panel the cells absorb the energy and through a complicated process create an electric field.

PolyCrystalline or MultiCrystalline solar panels are solar panels that consist of several crystals of silicon in a single PV cell. Several fragments of silicon are melted together to form the wafers of polycrystalline solar panels. These solar panels are made of multiple photovoltaic cells. Each cell contains silicon crystals which makes it function as a semiconductor device.
