Rooftop PV systems, in particular, have been deployed on a large scale in industrial plants, commercial buildings, and residential buildings due to their advantages such as requiring no additional land resources and flexible installation. However, rooftop PV systems are highly susceptible to external environmental factors during long-term operation, with dust accumulation on the surface of PV modules becoming one of the key bottlenecks restricting the stable improvement of their power generation efficiency. Therefore, auxiliary cleaning components are needed to prevent dust accumulation.

[0003] In response, Chinese patent application number CN202221844523.0 discloses a photovoltaic panel cleaning structure to prevent dust accumulation, belonging to the field of photovoltaic panel cleaning devices. It includes a cleaning frame, with a motor installed at the left end of the cleaning frame and a threaded rod connected to the right end of the motor. The outer surface of the threaded rod is threadedly fitted with a drive plate. This photovoltaic panel cleaning structure to prevent dust accumulation has suction nozzles on both sides of the brush used to clean the dust on the surface of the photovoltaic panel. The suction nozzles have the function of absorbing the dust swept out by the brush and discharging it from the left side of the cleaning frame, preventing the dust swept out by the brush from falling back onto the surface of the photovoltaic panel and causing secondary pollution.
