Polycrystalline Solar Panels is composed of polycrystalline silicon solar cells, EVA film low toughened glass, light electroplating rate gold. Polycrystalline silicon is an aggregate containing a large number of single crystal particles. Typically, Polycrystalline solar panels have an efficiency of about 18 percent. Output power of polycrystalline solar panels is strictly controlled at + / - 3% to ensure positive tolerances for each container. Its components are tested by internationally renowned laboratories to ensure the accuracy of output common rate. In the process of component production, advanced technology without screw built-in corner key connection is applied to tighten seal, with high mechanical strength and high transmittance, toughened glass package and sealed waterproof junction box are adopted to ensure the safety of components. The output power of these pv modules is guaranteed to be over 90% during the 10 years of use. During 25 years of use, the output power is above 80%. The packaging form and accessories such as junction boxes selected by polycrystalline solar panels meet the requirements of field use and the protection level reaches IP65. The module can resist wind speed of 120Km/h, and its strength can resist general wind sand, hail and snow pressure.
