An apparatus for charging a battery of a vehicle includes at least one
photovoltaic cell that is adapted to convert solar insolation into
electricity. The position of each photovoltaic cell is varied so that it
faces toward a current location of the sun whether the vehicle is
stationary or moving whenever the sun is visible. The apparatus is
preferably disposed in a spoiler. The spoiler is either permanently
attached to or is detachably-attachable with respect to the vehicle. The
spoiler helps improve stability and handling at higher vehicle speeds as
well as providing for the supplemental charging of the battery. The
spoiler adds to the aesthetic appeal of the vehicle while helping to
camouflage its primary purpose as that of a solar charging device.
