The function of the solar panel is to convert the sun's light energy into electrical energy, and then output the DC power to the battery. Solar panel is one of the most important components in a solar power system. Its conversion rate and service life are important factors that determine whether a solar cell has value in use.
Solar module design: According to the International Electrotechnical Commission GB / T9535-98 and IEC61215 standards, the battery chips are designed in accordance with the GBT6495 standard requirements. 36 or 72 polycrystalline silicon solar cells are connected in series to form various types of 12V and 24V modules. The solar module can be used in various household photovoltaic systems, independent photovoltaic power stations and grid-connected photovoltaic power stations. Characteristics of raw materials Cells: High-efficiency (above 15.5) polysilicon (single-crystal silicon above 16.5) solar cell packages are used to ensure sufficient power generation of solar panels. Glass: Low-iron tempered suede glass, also known as white glass, with a thickness of 3.2mm in the wavelength range of the solar cell's spectral response of 320-1100nm and a light transmittance of more than 91, has a high reflectance for infrared light greater than 1200nm. The glass is also resistant to the sun's ultraviolet radiation and the transmittance does not decrease. EVA: Uses a high-quality EVA film layer with a thickness of 0.78mm added with anti-ultraviolet agents, antioxidants and curing agents as the sealant for solar cells and the connecting agent with glass and TPT. Has a 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 it slightly improves the efficiency of the module, and because of its high infrared emission rate, it can also reduce the operating temperature of the module. Conducive to improving the efficiency of the component. Of course, this fluoroplastic film first has the basic requirements of aging resistance, corrosion resistance and air tightness required by solar cell packaging materials.
