Solar panels are one of the most important components in a solar power system. The function is to convert the light energy of the sun into electrical energy, and the output DC power is stored in the battery. Its conversion rate and service life are important factors in determining whether solar cells are useful. 36 or 72 polycrystalline silicon solar cells were used 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 plants and grid-connected photovoltaic power plants.
The cell is packaged in a high efficiency (16.5% or more) single crystal silicon solar cell package to ensure sufficient power generation of the solar cell panel. The glass is made of low-iron tempered suede glass (also known as white glass), which has a transmittance of more than 91% in the wavelength range of the solar cell's spectral response, and a high reflectance for infrared light of more than 1200 nm. The glass is also resistant to radiation from the sun's ultraviolet light, and the light transmittance does not decrease. EVA uses a high-quality EVA film with an anti-UV agent, an antioxidant and a curing agent with a thickness of 0.78 mm as a sealing agent for solar cells and a connecting agent with glass and TPT. It has high light transmittance and anti-aging ability. The back cover of the TPT solar cell - the fluoroplastic film is white, reflecting the sunlight, so the efficiency of the component is slightly improved, and because of its high infrared emissivity, it can also reduce the operating temperature of the component. Conducive to improving the efficiency of components. The aluminum alloy frame used in the frame has high strength and strong mechanical shock resistance. It is also the most valuable part of solar power systems. Its role is to convert the solar radiation capacity into electrical energy, or send it to the battery for storage, or to drive the load.
