Abstract: A solar panel(s) positioning apparatus for controlling the orientation of a solar panel(s) having one edge pivotally mounted to a support surface including a lift bar attached to an opposite edge of the panel(s) and having a mast, a base supported on the support surface, a swing link connected between the base and the mast and an extensible link pivotally connected between an intermediate point on the base end of the mast. A modification of the structure includes positioning apparatus for alternate bidirectional tilting of one or more panels about axes along aligned opposite side edges thereof.
