An apparatus is provided that comprises photovoltaic cells provided on a first rotatable member, an electric motor having an axial shaft, and a second rotatable member provided with an impeller. The photovoltaic cells capture and convert the solar energy into electrical energy. The electric motor is connected to and is in electric communication with the photovoltaic cells for powering the electric motor. The electric motor converts the electrical energy into mechanical energy for rotating the photovoltaic cells in a first direction about a central axis and for rotating the axial shaft connected to an impeller in a second direction about the central axis. The rotating axial shaft rotates the impeller at high revolutions per minute which generates a flow of air that is directed to the rotating photovoltaic cells on the first rotatable member. The photovoltaic cells are cooled by the air-flow and operate at a lower temperature.
