Characteristics of solar module raw materials
Battery: high efficiency (16.5% above) monocrystalline silicon solar chip package, to ensure sufficient power generation of solar panels.
Glass: low iron tempered suede glass (also known as white glass), thickness of 3.2mm, in the solar cell spectral response of the wavelength range (320-1100nm) light transmittance of more than 91%, for more than 1200nm infrared light has a higher reflectivity. This glass can withstand the radiation of the sun's ultraviolet rays at the same time, and the light transmittance does not decrease.
EVA: An EVA film layer with a thickness of 0.78mm, which is added with an anti-ultraviolet agent, an antioxidant and a curing agent, is used as a sealant for solar cells and a connecting agent between glass and TPT. It has high light transmittance and aging resistance.
TPT: The back cover of the solar cell-fluorine plastic film is white, which reflects the sunlight, so the efficiency of the component is slightly improved, and because of its high infrared emissivity, it can also reduce the working temperature of the component, and it is also beneficial to Improve the efficiency of the component. Of course, the fluorine plastic film first has the basic requirements such as aging resistance, corrosion resistance, and air impermeability required by the solar cell packaging material.
Frame: The aluminum alloy frame used has high strength and strong mechanical impact resistance. It is also a high-value part of the solar power system.
