Abstract: A device for converting Sunlight into electrical energy which can be used to maintain a charge in a battery includes at least one translucent panel having a plurality of individual electrically connected solar cells mounted therein. The translucent panel is mounted in a frame which can support the panel on a mounting surface. This frame includes a peripheral support wall and a panel support surface extending therebetween. The peripheral support wall has an upper edge and the support surface is located at a level below the upper edge of the peripheral wall thereby to support the panel within the confines of the wall.
