A mounting assembly may include an arced connecting member that includes a first drive chain along a bottom surface of the arced connecting member, a second drive chain positioned adjacent to the first drive chain, and a third drive chain in a gap between the first and the second drive chains. The mounting assembly may include an intermittent-motion drive system that has a drive wheel with a nub extending from a lateral surface of the drive wheel, the nub being shaped to interface with notches included along the third drive chain. The intermittent-motion drive system may include a first and a second protrusion shaped to interface with surfaces of the first and second drive chains, respectively. Rotation of a drive axle extending through the drive wheel may affect rotation of the drive wheel, rotational movement of the nub extending from the drive wheel, and movement of the arced connecting member.

A mounting system includes a footer having a cavity section and a cover section. The cavity section includes: a base and a first patterned wall extending upward from the base to at least partially define a cavity; and a hole for receiving a connector to attach the footer to a fixed surface. The cover section is releasably attachable to the cavity section and has a second patterned wall. An intermediate support has a stem and a head, at least two sides of the stem have a pattern, the head having at least one support surface shaped to supporting an object and a lock configured to secure the object to the head. The first patterned wall, the second patterned wall and the pattern on the two sides of the stem collectively define a plurality of defined height and width positions for the intermediate support to align relative to the footer.

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.
