The invention relates to a water membrane dedusting photovoltaic panel. The water membrane dedusting photovoltaic panel comprises a power generation panel, a shell and a bracket. The shell is fixed by the bracket. The shell is provided with an upper cover plate. A transparent protective plate is adhered on the light collecting surface of the power generation panel. The power generation panel is horizontally arranged in the shell, and the light collecting surface of the power generation panel is upward. The power generation panel is electrically connected with integrated chips and power storage elements. The bottom part of the shell is provided with poking wheels which are driven by a driving motor. The shell is internally filled with adsorption liquid. The liquid level of adsorption liquid exceeds the protective plate. The bottom part of the shell is also provided with a filter. The photovoltaic panel is novel and unique in structure, can effectively prevent generation of the hot spot effect and has relatively long service life.
