The characteristics of raw materials of Sufu solar system
What is the design principle of the solar system and what are its characteristics?
Characteristics of raw materials for solar energy systems:
Cells: Use high-efficiency (17.5% or more) solar cell packaging to ensure sufficient power generation from solar panels.
Glass: Use low-iron tempered suede glass (also known as ultra-white glass), with a thickness of 3.2mm, and a light transmittance of more than 91% within the wavelength range of the solar cell's spectral response (320-1100nm). For infrared greater than 1200 nm Light has a higher reflectivity. This glass is also able to withstand the radiation of solar ultraviolet light, and the light transmittance does not decrease.
Frame: The aluminum alloy frame used has high strength and strong resistance to mechanical shock.
Solar panel EVA: The high-quality EVA film layer with a thickness of 0.78mm with anti-ultraviolet agent, antioxidant and curing agent is used as the sealing agent of the solar cell and the connecting agent between the glass and TPT. It has high light transmittance and anti-aging ability.
Solar panel TPT: The back cover of the solar cell-the fluoroplastic film is white, which reflects sunlight, so the efficiency of the module is slightly improved, and because of its higher infrared emissivity, it can also reduce the work of the module Temperature is also conducive to improving the efficiency of components. Of course, this fluoroplastic film firstly has the basic requirements of aging resistance, corrosion resistance, and gas impermeability required by solar cell packaging materials.
