Polycrystalline cells are composed of multiple silicon crystals, which is a cheaper way to manufacture solar modules. Put simply, these cells are easier for a factory to produce, so they are less expensive. Polycrystalline cells are made by several methods, but most commonly with a cast of molten silicon.
What is Poly Resin? Poly Resin describes our patented bed frame which is constructed from co-extruded, furniture-grade materials. Using two different types of plastic that are fused together, the inside material provides great structural strength while the harder outer shell provides a beautiful, furniture grade finish. This outer layer has a glossy finish that is extremely resistant to damage by chemicals. By combining these two types of PVC in our frame, we can provide a product that can endure a wide range of environments. Note the hard, glossy outer finish and the white inner, structural material.
