In the practical application of solar photovoltaic power generation, photovoltaic modules are the most important unit of power generation, and their output power is directly affected by the intensity of sunlight. When sand, dust, and snow fall on the surface of photovoltaic modules, the light transmittance will be reduced, resulting in a significant decrease in photoelectric conversion efficiency. This problem is particularly serious in the central and western regions where wind and sand are relatively large. Therefore, in order to maintain the power generation efficiency of the photovoltaic power station, it is very important to clean the photovoltaic modules of the photovoltaic power station, and the cleaning of the photovoltaic modules of the photovoltaic power station has become an indispensable key link in the construction of photovoltaic power stations.
