The invention discloses a cleaning device for a solar energy panel. The cleaning device comprises the solar energy panel, a fixed chain, a rotating chain, a first gear and a T-shaped fixed rod. The cleaning device for the solar energy panel is simple in structure, by adding structures such as a second gear, a rotating rod, a spring, a cleaning rod, a motor, a first connecting rod, a second connecting rod, a plastic shovel, a cleaning brush, cleaning cloth and a cleaning claw, and due to rotating of the motor the first gear, the second gear and the rotating chain are driven to rotate, and thenthe cleaning device is rotated accordingly; and in the whole moving process of the cleaning device, first, large particle matter on the surface of the solar energy panel is cleared through the plasticshovel, then the surface of the solar energy panel is scrubbed through the cleaning brush, so that dust on the surface of the solar energy panel is removed, and finally, the surface of the solar energy panel is wiped through the cleaning cloth.
