Abstract: A bearing for a solar mounting system, the bearing comprising a bushing assembly configured to accept a torque tube. It has a front bushing, a back bushing to accept a torque tube, a stop ring sandwiched between each of the front bushing and the back bushing, a bushing housing configured to retain the bushing assembly. A coupler extends through the bearing to connect the front and back bushings to the housing, wherein during rotation of the bushings, the stud of the stop ring is configured to mate with the coupler to halt a rotation of the front busing and the back bushing to thereby distribute a torsional force along the solar mounting system.

Abstract: A solar panel rail for mounting a photovoltaic module frame thereto is provided and has a rail body configured to for attachment of a rail bracket, an indexing flange located on the rail body and configured to box and maintain a module frame position along a short-side direction of the module frame, a tab located on the rail body and configured to hold the module in place along a long-side direction of the module frame, wherein the indexing flange and tab are configured to provide a predetermined locked in installation position of the module frame during installation thereof.
