A second solenoid valve is arranged on the liquid infusion pipe. The image acquisition unit can collect the type of stains on the photovoltaic panel 300. The control device is connected to the first solenoid valve and the second solenoid valve, and is used to control the working state of the first solenoid valve and the second solenoid valve respectively based on the stain type results collected by the image acquisition unit.

[0047] The image acquisition unit can collect the state of stains on the photovoltaic panel 300, and the state of stains includes but is not limited to the type of stains, dust thickness, agglomeration hardness, and dust distribution images, etc. For example, before the cleaning operation, the image acquisition unit collects that the stains on the photovoltaic panel 300 are only light dust, and the control unit controls to start the purge unit. If after the purge cleaning is completed, the image acquisition unit collects that the cleanliness of the photovoltaic panel 300 meets the standard, and the control unit can turn off the photovoltaic panel 300 cleaning device. If after the purge cleaning is completed, the image acquisition unit collects that there are still stains on the photovoltaic panel 300, and then starts the purge unit and / or the spray unit. In general, the photovoltaic panel 300 cleaning device can adjust the working state of the first solenoid valve and the second solenoid valve according to different stain states before and during the cleaning operation to achieve different modes of cleaning operations, thereby saving the cleaning time cost and saving water.
