Abstract: A wind load resistant, tracking photovoltaic solar array system may include a pivot support; at least one solar cell coupled to the pivot support; and a pivot arm coupled to the solar cell for providing transverse movement of the solar cell relative to a longitudinal axis of the pivot support. A transverse drive motor may be coupled to the pivot arm for rotating the pivot arm in response to control signals. A tube for housing the solar cell, pivot arm, and the transverse drive motor may also be included. A support structure may be coupled to the tube and for mounting the tube against another structure, such as a building rooftop. A longitudinal axis drive motor may be coupled to the tube and the support structure. The longitudinal axis drive motor may rotate the tube around a geometrical longitudinal axis of the tube in response to control signals.
