When a solar module is placed on the mounting bracket and supported by the torque tube the mounting tab retainer assembly is received in the mounting slot of the solar module.

A solar panel support apparatus comprising: a support frame for holding the solar panel; a support post pivotally connected to the support frame at a post pivot connection and anchored to an adjacent supporting surface, the support post for positioning the support frame above the supporting surface; and a linear actuator coupled at a proximal end to the support post by a support pivot connection and at a distal end by a frame pivot connection with the support frame, the post pivot connection and the frame pivot connection spaced apart from one another on the support frame; wherein a change in a length of the linear actuator results in pivoting of the support frame about the post pivot connection.

A movement control apparatus for a heliostat device may include a step motor, a decelerating motor, a ball screw assembly, a nut, a connecting shaft, and a linear moving shaft. In one embodiment, the nut is movably connected with the ball screw assembly and is secured on a first connecting board and a second connecting board through the connecting shaft. The nut is driven by the ball screw assembly to travel along the screw shaft and since the nut is connected to the connecting boards through the connecting shaft, and the connecting boards are connected to the moving shaft, the movement of the nut can further drive the connecting shaft to rotate to drive the moving shaft to move in a linear manner on the sliding rail to rotate a mirror assembly of the heliostat around a post.

A solar tracking system for tracking the orientation of solar energy is disclosed. The solar tracking system may be integrated with solar cells and solar concentrators. The solar tracking system may have a first (22) and second (24) tracker module array that are opposite from another, aligned in substantially identical orientation, and form a tracker module pair array (1000). Tracker module pairs (12, 14; 12, 144) may allow motion relative to one another while maintaining substantially identical orientation. Solar concentrators may be attached to opposing tracker modules of a tracker module pair forming an array of solar concentrators. A base bar array (28) may be coupled to at least one tracker module pair. A transmission may operably rotate the base bar array and the tracker module pair array simultaneously.
