NOVELTY - The system has a fixture, revolving mechanism, and a cell module (10) including a set of cells (2) for converting sunlight into electric energy. A lens module (20) has a set of lenses, which are provided corresponding to the cells for collecting sunlight. A loading plate (29) of the lens module is arranged with multiple convex lenses (12) that are installed at a lens installation hole part. A space is formed in an upper slope part of the hole part, which is larger than a space of a perpendicular part that is set at an upper side of a lower slope part of the hole part.    USE - Solar power system for use on rooftop of a home and a vehicle (claimed) such as refrigeration van truck, advertisement vehicles, large size top, bus and camping car.    ADVANTAGE - The system utilizes the cell module with cells and the lens module with convex lenses, thus increasing amount of electric power, which is gathered on the cells, and hence minimizing an isometrical cell module comparison power production and size of identical power production comparison cell module. The system replaces damage of the convex lenses among the partially damaged convex lenses. The management cost of the system is inexpensive. The initial insertion and installation of the convex lenses are facilitated. The system is simple in structure and convenient to assemble. The convex lenses are not protruded to an outside of the lens mounting plate, so that damage of the convex lens is minimized. The fixture has waterproof function for fixing the lens that are to be inserted into the lens installation hole portion, thus preventing infiltration of rainwater or foreign material to the module. The system facilitates molding of the lens module, and eliminates separate lens installation process. The operation process of the system is simple, and the spacer is arranged to an edge of the lens module, thus preventing the strong module, which is diagonally arranged with the lens module. The lens module maintains optimum state, and the system prevents collision of the strong module with the lens module. The revolving mechanism is rotated on the system, so that the cell and lens modules are rotated according to the sunlight, so that electricity is produced for a long time with high generation efficiency. The edge of the system is covered by the cap, thus producing large amount electricity for the vehicles. The system has a screwnut connected in a bolt, so that the system is secured in an effective manner.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a vehicle e.g. camping car, with a solar power system.    DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a solar power system.    Cells (2)    Cell module (10)    Convex lenses (12)    Lens module (20)    Loading plate (29)
