Raw material properties
Battery: High efficiency (17.5%) monocrystalline silicon solar chip package to ensure adequate power generation of solar panels.
Glass: Low iron tempered 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 has a higher Of the reflectivity. This glass can also control the sun's ultraviolet radiation, light transmission rate does not decline.
Eva: A high quality eva film with anti-ultraviolet, antioxidant and curing agent thickness of 0.78mm, used as a solar cell sealant and glass and tpt linker. With high light transmission and anti-aging ability.
Tpt: solar cell back cover - fluorine plastic film is white, reflecting the role of the sun, so that the efficiency of a slight increase in components, and because of its high infrared emissivity, but also reduces the component's operating temperature, but also help improve the components effectiveness. Of course, this fluorine plastic film first with solar cell packaging materials need anti-aging, corrosion resistance, sealing and other basic requirements.
Border: aluminum frame high strength, strong resistance to mechanical shock. Solar panel parameters solar panel specifications
