Battery chip
Monocrystalline silicon solar chips (above 16.5%) are adopted for packaging to ensure sufficient power generated by solar panels.
Glass
Low iron tempered suede glass (also known as white glass) with a thickness of 3.2 mm is used, and the transmittance in the wavelength range of solar cell spectral response (320-1100 nm) is more than 91%. It has a high reflectivity for infrared light greater than 1200 nm. At the same time, the glass can withstand the radiation of solar ultraviolet light without decreasing the transmittance.
EVA
The EVA film with a thickness of 0.78mm added with anti ultraviolet agent, antioxidant and curing agent is used as the sealant of the solar cell and the connector with the glass and TPT. It has high light transmittance and anti-aging ability.
TPT
The back cover of the solar cell - fluoroplastic film is white, which reflects sunlight, so the efficiency of the module is slightly improved. Because of its high infrared emissivity, it can also reduce the working temperature of the module, and is also conducive to improving the efficiency of the module. Of course, this fluoroplastic film first has the basic requirements of aging resistance and air tightness required by solar cell packaging materials.
Frame
The aluminum alloy frame used has high strength and strong mechanical impact resistance. Its function is to convert the solar radiation capacity into electric energy, or send it to the storage battery for storage, or promote the load work.
