As one of new energy power generation technologies with a wide prospect, solar photovoltaic power generation has been rapidly developed in recent years. However, in the power generation process, the accumulated dust of the photovoltaic panel not only blocks the heat transfer, increases the surface temperature of the photovoltaic panel and reduces the energy conversion efficiency, but also forms a shielding effect and influences the light energy absorption; in a humid environment, dust with acidic or alkaline chemical properties can also corrode the surface of the photovoltaic panel due to chemical reactions. The research shows that: only 4g/m on the photovoltaic panel2The amount of particle deposition of (a) can reduce the power output of the photovoltaic power generation system by 40%.
