Abstract

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 (101) 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.
