NOVELTY - The apparatus has a photovoltaic cells (102) which is housed on a rotatable element (101) connected to a rotary object to capture solar energy and to convert solar energy into electrical energy. An electric motor (103) rigidly connected to rotatable element, converts electrical energy produced by photovoltaic cells into mechanical energy and rotates about axial shaft. The rotation of rotatable element housing photovoltaic cells by electric motor removes heat from the photovoltaic cells and causes rotation of connected rotary object (105).    USE - Solar power wheel apparatus connected to wheel of vehicle e.g. car, helicopter, bicycle, train, rotating amusement riding apparatus e.g. carousel, space vehicle skateboard, automobiles e.g. motorbikes, trams, carriages, wheel chars, tractor, and foam equipment flying toys.    ADVANTAGE - Since the rotation of rotatable element housing photovoltaic cells by electric motor removes heat from the photovoltaic cells and causes rotation of connected rotary object, the efficiency of the solar devices is increased and the electrical energy is outputted during operation of the solar powered wheel apparatus. Since the rotation of the electric motor rotates the rigidly connected rotatable element housing photovoltaic cells when photovoltaic cells convert solar energy into electrical energy, the photovoltaic cells ensures an extended life span or better mean time before failure (MTBF) of the photovoltaic cells. Since the photovoltaic cells operate at a much lower temperature, better efficiency in electrical energy output is offered. The life span of the photovoltaic cells is extended and sustained, before mechanical efficiency of the photovoltaic cells is reduced.
