Using method of water photovoltaic panel cleaning device

The invention discloses a use method of an overwater photovoltaic panel cleaning device, and the method comprises the steps: collecting surface images of a plurality of target photovoltaic panels, and obtaining target image data; for the target image data, generating a cleaning instruction according to a preset cleaning strategy; the cleaning instruction is used for indicating the cleaning device to execute corresponding cleaning operation. The method has the beneficial effects that the target image data is obtained by collecting the surface images of the multiple target photovoltaic panels, the obtained target image data is compared with the original image data, the pollution level is determined according to the comparison result, and the corresponding unique cleaning instruction is generated according to the pollution level in combination with the preset cleaning strategy; the surface of the photovoltaic panel can be simply scraped and cleaned through the cleaning assembly; the surface of the photovoltaic p
