Solar trackers that may be advantageously employed on sloped and/or variable terrain to rotate solar panels to track motion of the sun across the sky include bearing assemblies and other mechanical features configured to address mechanical challenges posed by the sloped and/or variable terrain that might otherwise prevent or complicate use of solar trackers on such terrain.

A solar panel awning device may include a solar panel having first and second opposing ends, first and second opposing sides extending between the first and second opposing ends, and first and second opposing major surfaces. The first major opposing surface defines a photovoltaic surface. The solar panel awning device may include first and second arms respectively coupled to the first and second opposing ends of the solar panel, and an actuator coupled to one of the first and second arms and configured to switch the solar panel between an extended position and a retracted position. In the retracted position, the solar panel is flat against a side of a building; in the extended position, the first opposing side is proximal to the side of the building and spaced apart from the side of the building; and the second opposing side is distal to the side of the building.

A solar tracker comprises a support frame, a panel assembly comprising one or more solar panels, and an actuator to rotate the panel assembly to track the movement of the sun. The panel assembly comprises a central spine and one or more panel carriers extending transversely over the top of the central spine for supporting solar panels. The panel carriers are secured to the central spine by respective support brackets. The support brackets comprise a top surface, side walls extending downwardly from opposing sides of the top surface, and a slot with a downwardly facing opening extending transversely through the sidewalls. The slot is configured to receive the central spine.

Tracking systems for adjusting a photovoltaic array are disclosed. In some embodiments, the tracking system includes an actuator that moves one or more links to cause the array to rotate. The tracking system may be disposed below a torque rail of the tracking system. The actuator may be a slew drive that retracts or extends the one or more links to cause the array to rotate.
