Problems solved by technology

However, under daily conditions, many factors will affect the power generation efficiency of solar panels, resulting in low efficiency of solar power generation devices, mainly in the following aspects: (1) The collection of dust in the air on the surface of solar panels prevents it from receiving the sun. The total amount of absorption reduces the efficiency of the solar power generation system; (2) The surface of the solar panel is prone to frost in cold winter, and the melting of the frost layer reduces the effective power generation time of the solar panel; (3) The solar battery under high temperature conditions in summer Some areas of the panel are prone to overheating, resulting in a significant reduction in the power generation efficiency of the solar panel
