   The output power of polycrystalline solar panels is strictly controlled at ±3% to ensure positive tolerance for each container. Its components have been tested by internationally renowned laboratories to ensure the accuracy of the output ratio. In the module production process, advanced technology of screw-free built-in angle key connection is applied, which is tightly sealed and has high mechanical strength. High transmittance tempered glass is used for encapsulation and sealed waterproof junction box to ensure the safety of the module and ensure the safety of these photovoltaic modules. During 10 years of use, the output power is above 90%; during 25 years of use, the output power is above 80%. The packaging form and junction box and other accessories selected for the polycrystalline solar panels meet the requirements for outdoor use, and the protection level reaches IP65. The wind pressure resistance of the module reaches 2400 Pa, and it can withstand wind speed of 120Km/h. The module strength can withstand general wind sand, hail and snow pressure.
