Abstract: An image/video capture apparatus is provided, to capture image data of a photovoltaic panel (101) and surroundings, and a controller (502) recognizes a category corresponding to the image data, and generates different instructions to control rotation of a photovoltaic tracker (102), to remove dust or snow accumulating on the photovoltaic panel (101). This does not need continuous heating, but is simple and efficient, saves electric energy, and resolves a technical problem that a conventional snow removal method of heating has low efficiency and wastes electric energy. In addition, a corresponding controller (1200) is further provided.
