Poly solar panels are composed of poly silicon high-efficiency solar cells, EVA film low-tempered glass, and light electroplating rate gold. It can be used for solar street lights, solar lawn lights, solar power generation systems, communications, aerospace and other ways. Polycrystalline silicon contains a large number of aggregates of single crystals, and has a single component with various alignment directions. It is made by melting, casting and solidifying waste monocrystalline silicon materials and metallurgical grade silicon materials. Its manufacture is simple and the cost is low.
