The offshore photovoltaic has two basic forms of fixed type and floating type, and compared with a fixed type basic structure, the floating type basic structure has the advantages of being larger in applicable water depth, more convenient to recycle, large in generating capacity and the like. The main parts of the offshore floating type photovoltaic system comprise a photovoltaic panel, a combiner box, inverter equipment, a transformer, a floating cable, a floating body stand and the like. Because of the influence of wind and waves, the floating body stand is generally of a circular structure, and the photovoltaic panels arranged on the floating body stand are also generally of a layout and a shape which are more similar to a circular shape for the consideration of the utilization rate, such as a hexagon and the like, and an automatic cleaning device for square photovoltaic panels suitable for land is not matched with the shape of the photovoltaic panels; on the other hand, the offshore operation cost is higher, so that the resources such as cleaning water and the like cannot be timely supplemented like a cleaning device on land.
