The solar home system is SHS (Solar Home System) mainly refers to the small photovoltaic power generation system installed in office buildings, residences, etc., to supply power for the residents themselves. During the day, the power generation system charges the battery; at night, the power generation system charges the battery The stored electric energy is discharged by inverter to realize power supply to household loads. Its main components are photovoltaic modules, which will be introduced below for you.
Solar panels are the core part of the solar power generation system and the most valuable part of the solar power generation system. Its function is to convert solar energy into electric energy, or send it to storage battery for storage, or push the load to work. The quality and cost of solar panels will directly determine the quality and cost of the entire system.
Raw material characteristics:
Cells: High-efficiency (16.5% or more) monocrystalline silicon solar cells are used to package 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. The light transmittance of the solar cell's spectral response wavelength range (320-1100nm) is above 91%. For infrared light greater than 1200nm Higher reflectivity. This glass is also resistant to solar ultraviolet radiation, and the light transmittance does not decrease.
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 solar cells and the connecting agent between glass and TPT. 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 first has 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 shock. It is also the most valuable part of household solar power generation.
