ABSTRACT:
A mechanism for elevationally driving a solar concentrator pivotally mounted on a pedestal between a zenith facing position, a horizon facing position, a downward facing position, and any intermediate position, using a single linear actuator. A lower bar is pivotally connected to the pedestal and an upper bar is pivotally connected to the solar concentrator. The lower bar and the upper bar are connected to a slider having a follower nut section which is driven by a linear actuator, having a motor driven lead screw, which is attached to the pedestal or an offset support structure portion of the solar concentrator.
