Polycrystalline Solar Panels
Polycrystalline cells have a visible appearance of shattered glass. This is a result of using a number of different crystals in the manufacturing process. They are slightly cheaper to produce than Mono panels. However, they are also less efficient. When compared to Monocrystalline solar panels, Poly cells have an efficiency of 0.5%-2% less, requiring more cells to produce equal amount of energy.
