The front face has a plurality of operating components including a display, a plurality of keys, a microphone, and a speaker situated thereon for allowing conventional usage of the telephone. A planar rectangular solar panel is coupled to the rear face of the telephone. The solar panel is adapted to convert ambient light into electric power. At least one rechargeable battery is situated within the interior space of the telephone and electrically connected to the operating components of the phone for supplying power thereto. Finally, power connection circuitry is electrically connected between the solar panel and the batteries. The power connection circuitry is adapted to permit the flow of power from the solar panel to the at least one battery and further preclude the flow of power from the at least one battery to the solar panel.
