Get PriceMonocrystalline vs. Polycrystalline Solar Panels
Monocrystalline solar cells are made from a single silicon crystal, like a silicon wafer. Because they''re pure and uniform, these cells usually have a higher efficiency rate. Now, polycrystalline solar cells are made up of a bunch of crystals, which can slow down the movement of electrons, making them a tad less efficient.
