Mono-crystalline Solar Panels

To make solar cells for mono-crystalline solar panels, silicon is formed into bars and cut into wafers. These types of panels are called “mono-crystalline” to indicate that the silicon used is single-crystal silicon. Because the cell is composed of a single crystal, the electrons that generate a flow of electricity have more room to move. As a result, mono-crystalline panels are more efficient than their poly-crystalline counterparts.
