Polycrystalline Solar Panels Raw Material Characteristics

Polycrystalline Solar Panels Polycrystalline solar panels are made of polycrystalline high efficiency solar cells, EVA film low tempered glass, light plating rate of gold composition. Can be used in solar street lights, solar lawn, solar power systems, communications, aerospace and other means. Polycrystalline is a collection of large amounts of monocrystalline particles, which have a variety of different arrangement of the single composition. With waste single crystal and metallurgical grade material melting casting solidification made. Its manufacture is simple and the cost is low. Usually the polycrystalline solar cell photoelectric conversion efficiency of about 18%.

Polycrystalline Solar Panels Glass: the use of low-iron steel velvet glass (also known as white glass), the thickness of 3.2mm, in the solar cell spectral response wavelength range (320-1100nm) light transmission rate of 91% or more, for more than 1200 nm infrared light Have a higher reflectivity. This glass can also control the sun's ultraviolet radiation, light transmission rate does not decline.

Polycrystalline Solar Panels EVA: A high-quality EVA film with an anti-UV, antioxidant and curing agent thickness of 0.78mm is used as a sealant for solar cells and a linker with glass and TPT. Has a high light transmittance and anti-aging ability.

The output power of the polycrystalline solar panel is strictly controlled at ± 3% to ensure that each container is positive tolerant. Its components through the internationally renowned laboratory testing to ensure the accuracy of the output rate. Polycrystalline Solar Panels In the process of component production, the application of non-screw built-in key to connect the advanced technology, fast seal, high mechanical strength, the use of high transmittance tempered glass package and sealed waterproof junction box to ensure the safety of components to ensure that these PV modules In the 10 years of use, the output power of 90% or more; 25 years of use, the output power of 80% or more.

Polycrystalline Solar Panels Polycrystalline solar panels used in the form of packages and junction boxes and other accessories to meet the requirements of the use of the field, the protection level to IP65. Component wind pressure reached 2400 Pa, able to withstand 120Km / h wind speed, component strength to withstand the general sand, hail and snow pressure.
