[0033] Installation frame 4; photovoltaic panel body 19 is installed in the installation frame 4;

[0034] Two mounting shells 8; the mounting shell 8 is formed into a long strip, and one side of the long side of the mounting shell 8 is open, and the two mounting shells 8 are mounted on opposite sides of the mounting frame 4, and the open sides of the two mounting shells 8 are arranged opposite to each other;

[0037] like Figure 2 As shown, a water inlet is provided on the upper side of one side wall of the water tank 20, and a drain outlet is provided on the lower side. Both the water inlet and the drain outlet are threaded interfaces, and both the water inlet and the drain outlet are closed by threaded pipe covers when not in use.

[0038] like Figure 1 and 4 As shown, the self-cleaning photovoltaic panel for photovoltaic power generation also includes two groups of positioning mechanisms 24 for positioning the brushing mechanism 23, the positioning mechanism 24 includes a fixing sleeve 10, a second electric telescopic rod 11, a connecting plate 12, and a baffle 13.
