The photovoltaic module cleaning system according to claim 6, further comprising a camera and a remote monitoring platform which are electrically connected, wherein the remote monitoring platform is in wireless communication with the controller, the camera is used for shooting a surface image of the first photovoltaic panel and sending the surface image to the remote monitoring platform, so that when workers look up the surface image and find that dust pollution exists on the surface image on the remote monitoring platform, the cleaning device and the spraying device are remotely controlled by the remote monitoring platform to clean the first photovoltaic panel.
8. The photovoltaic module cleaning system according to claim 7, further comprising an early warning device and a water level sensor, wherein the early warning device is located in a place where the remote monitoring platform is located, the water level sensor is located in the water tank, and the early warning device and the water level sensor are electrically connected with the remote monitoring platform respectively, so that when the water level sensor detects that the water level in the water tank is lower than a preset height, the remote monitoring platform controls the early warning device to output water adding prompt information.
9. The photovoltaic module cleaning system of claim 8, wherein the pre-warning device is at least one of an indicator light, a buzzer horn, and a display device.
10. The photovoltaic module cleaning system according to claim 8 or 9, wherein the remote monitoring platform comprises a neural network recognition circuit, the neural network recognition circuit performs image recognition on the surface image, and when the first photovoltaic panel is recognized to have dust pollution, the early warning device is controlled to output cleaning prompt information.
