1. In terms of types, solar panels can be divided into single crystal and polycrystalline.
Monocrystalline silicon solar panels have higher efficiency and smaller light attenuation, but they are expensive. Polycrystalline silicon solar panels have relatively lower efficiency but lower prices.
2. There are many specifications for the external dimensions of solar panels, and it is necessary to determine which size is more suitable based on the installation environment of your street lights. Generally speaking, for the same power, choosing a smaller size is more suitable.
3. The power generation capacity of solar panels is closely related to light intensity, environmental temperature, installation angle, etc. The changes in each link will affect its power generation efficiency.
4. The raw materials and battery components generally include battery cells, EVA, back panel, aluminum alloy frame, tempered glass, and other parts. If inferior battery cells are used, irregular phenomena will occur, defects will occur during the lamination process, and copper, tin, and copper will bend and tighten; And it will produce bubbles, which proves that residual gaps will still be generated during the heating and sealing process at 160 degrees Celsius. The battery cells attach great importance to sealing and oxidation prevention, otherwise it will have a service life of 1-2 years in the open air, including filling the frame gaps, which are important links in the process.
