When the photovoltaic panel 4 is adjusted in angle again, the support rod 162 moves downward and no longer contacts and pushes the pressing rod 176 to start moving downward, and then the pressing rod 176 is driven by the movable end of the elastic telescopic rod 175 to start moving upward and reset.

This helps the water, cleaning liquid and dirt washed off used in the cleaning process to flow more smoothly from the surface of the photovoltaic panel 4 under the action of gravity, so as to avoid residue. In this way, the possibility of water stains and dirt residue can be reduced, the photovoltaic panel 4 can be cleaned more thoroughly, and the light transmittance and power generation efficiency of the photovoltaic panel 4 can be better ensured.
