Solar panel is one of the important components in the solar power generation system. Its function is to convert the light energy of the sun into electric energy, and then output DC power to store in the battery. Its conversion rate and service life are important factors that determine whether the solar cell has use value. 36 or 72 polysilicon solar cells are connected in series to form various types of components of 12V and 24V. The module can be used in various household photovoltaic systems, independent photovoltaic power stations and grid connected photovoltaic power stations.
The cells are packaged with high-efficiency (above 18%) monocrystalline silicon solar cells to ensure sufficient power generation of solar panels. The glass adopts low iron tempered suede glass (also known as white glass), which has a light transmittance of more than 91% in the wavelength range of solar cell spectral response, and has a high reflectivity for infrared light greater than 1200 nm. At the same time, this glass can withstand the radiation of solar ultraviolet light, and the transmittance does not decrease. EVA adopts a high-quality EVA film with a thickness of 0.78mm added with anti UV agent, antioxidant and curing agent as the sealant of solar cells and the connecting agent with glass and TPT. It has high light transmittance and anti-aging ability. The back cover of TPT solar cell fluoroplastic film is white, which reflects sunlight, so the efficiency of the module is slightly improved. Because of its high infrared emissivity, it can also reduce the working temperature of the module and improve the efficiency of the module. The aluminum alloy frame used for the frame has high strength and strong mechanical impact resistance. It is also the most valuable part of solar power generation system. Its function is to convert the radiation capacity of the sun into electric energy, or send it to the battery for storage, or promote the load to work.
Household solar panel is the core part of solar power generation system. The function of solar panel is to convert the solar energy into electric energy, and then output DC power to store in the battery.
