The cover provides for the positioning of lengths of clean covering film over the solar panel thereby removing dust and other accumulations. A pair of rollers on opposite sides of the solar panel support a supply of film material which extends over the panel surface. Clean film material is advanced at a predetermined rate across the solar panel thereby continuously replacing the panel cover and preventing excessive dust accumulation.Field of SearchPlural roll | |
