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 mounting system including a rail and a clip. When a first notch of the rail receives a portion of a rib of the rail, the clip is positioned on the rail to receive an end of a first solar panel having a first thickness, and when a second notch of the rail receives the portion of the rib, the clip is positioned on the rail to receive an end of a second solar panel having a second thickness different than the first thickness of the first solar panel.

Edge blocks for a PV array comprising fastener or component holes for anchoring the array bonding the array and protecting array cabling. Edge blocks provide a favorable aerodynamic shape to help deflect incoming wind, the channel rainwater and to protect edge of the array. Methods having steps of placing modules contacting native topography or a smoothed or substantially flat portion of the ground in an array and holding the array together and down are also disclosed.
