What Is The Polycrystalline Solar Panel? Polycrystalline or multi-crystalline solar panels combine several non-uniform silicon crystals in a single PV cell. Several silicon fragments are melted to form wafers of polycrystalline solar panels. As there are multiple silicon crystals used in manufacturing, there is less space for electrons to flow.
