NOVELTY - The system has a sign frame (100) sufficient in size and dimension to display graphic material, and lighting unit to illuminate the graphic material. A photovoltaic solar module charges a battery, where the battery powers the lighting unit under selective control. A tensioning unit affixes the graphic material to the frame. An integrated solar lamp heating unit heats the lighting unit. A load management system controls the lighting unit and the heating unit. A mast integrated with the frame receives mounting structures to align and hold the solar module.    USE - Solar powered, internally illuminated, solar heated sign system for illumination of a billboard, signboard and outdoor sign.    ADVANTAGE - The system provides sign frame with an integrated, simple unit for attaching solar photovoltaic modules, thus maximizing the utilization of limited illumination unit, and hence increasing the efficiency of the system for superior lighting intensities and uniform illumination of internally illuminated signs and billboards with greater efficiencies due to a superior load control even in cold weather conditions. The frame provides pleasing outdoor signage in a style and size by utilizing solar energy for illumination. The solar photovoltaic module mounting device of sufficient strength and rigidity secures standard solar photovoltaic modules to the sign frame utilizing mounting masts integrated into the frame, thus ensuring that the masts and mounts provide secure anchorage for the solar modules in all weather conditions and wind loadings and weather tight access to the other elements of the device for wiring, and providing preferred orientation of the solar modules in any geographic location, and hence reducing the cost and enhancing the utility of solar module mounting and orientation of the system. The sign frame utilizes solar power in outdoor signage through the careful design and construction so as to eliminate wasted energy and light.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for performing a business transaction.    DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a simple sign frame.    Sign frame (100)
