Solar panels

The solar panel is the core part of the solar power generation system. The function of the solar panel is to convert the schematic diagram of the solar light energy grid-connected power generation system into electrical energy, and then output the DC power and store it in the battery. The solar panel is one of the most important components in the solar power generation system, and its conversion rate and service life are important factors that determine whether the solar cell has use value. Component design: According to the requirements of the International Electrotechnical Commission IEC: 1215: 1993 standard, 36 or 72 polycrystalline silicon solar cells are used in series to form various types of 12V and 24V components. The module can be used in various household photovoltaic systems, independent photovoltaic power plants and grid-connected photovoltaic power plants.

Features of raw materials: Cells: High-efficiency (above 16.5%) monocrystalline silicon solar cells are used to encapsulate 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, has a light transmittance of more than 91% in the wavelength range of solar cell spectral response (320-1100nm). For infrared light greater than 1200 nm have higher reflectivity. At the same time, the glass can withstand the radiation of solar ultraviolet rays, and the light transmittance does not decrease. EVA: A high-quality EVA film layer with a thickness of 0.78mm added with anti-ultraviolet agent, antioxidant and curing agent is used as the sealing agent of solar cells and the connecting agent between glass and TPT.

Has high transmittance and anti-aging ability. TPT: The back cover of the solar cell—the fluoroplastic film is white and reflects sunlight, so the efficiency of the module is slightly improved, and because of its high infrared emissivity, it can also reduce the operating temperature of the module, also Conducive to improving the efficiency of components. Of course, this fluoroplastic film must have the basic requirements of aging resistance, corrosion resistance, and airtightness required by solar cell packaging materials. Frame: The aluminum alloy frame used has high strength and strong resistance to mechanical impact. It is also the most valuable part of the solar power generation system. Its function is to convert the radiation capacity of the sun into electrical energy, or send it to the battery for storage, or drive the load to work.
