Poly Modules 340W 156*156mm 72 Cells Photovoltaic Solar Panels

Features:

Raw material characteristics:
Cells: Adopt high-efficiency (over 18%) monocrystalline silicon solar cell packaging to ensure sufficient power generation from solar panels.
Glass: Use low-iron tempered suede glass (also known as white glass) with a thickness of 3.2mm and a light transmittance of more than 91% in the wavelength range of the solar cell's spectral response (320-1100nm), for infrared light greater than 1200 nm Has a higher reflectivity. This glass is also resistant to solar ultraviolet radiation, and the light transmittance does not decrease.
EVA: The high-quality EVA film with a thickness of 0.78mm with anti-ultraviolet agent, antioxidant and curing agent is used as the sealing agent for solar cells and the connecting agent between glass and TPT. It has high light transmittance and anti-aging ability.
TPT: The back cover of the solar cell-the fluoroplastic film is white, which reflects the sunlight, so the efficiency of the module is slightly improved, and because of its higher infrared emissivity, it can also reduce the working temperature of the module. 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.
Frame: The aluminum alloy frame used has high strength and strong resistance to mechanical shock. It is also the most valuable part of household solar power generation.
