Solar Multi-crystalline Module

Multi-crystalline panels, also known as polycrystalline, are composed of silicon, which is similar to monocrystalline. Instead of just a single silicon crystal, manufacturers melt multiple pieces of silicon to form panel wafers. Polycrystalline solar panels have many crystals per cell, interfering with how electrons move, lowering efficiency. However, they are not as expensive as other solar modules in the market.
