Abstract: The present disclosure describes a solar power system including at least one mounting assembly including a rail, at least one framed solar module, and at least one clip to secure the solar module to the rail. The clip includes at least a pair of sidewalls extending from a top plate or rear wall, each sidewall including a slot, a recess, and a locking member, at least one of the slot, recess, or both include a serrated edge. The clips may secure a solar module to the rail by coupling to the frame of the solar module to a rail of the mounting assembly within the slots of the sidewalls. The clips may be secured to the mounting assembly by locking members positioned on a distal end thereof. The clips may establish an electrical grounding connection between the frame of the solar module and the rail.

Abstract: In an example, the solar tracker has a clamp assembly that is configured to pivot a torque tube. In an example, the assembly has a support structure configured as a frame having configured by a first anchoring region and a second anchoring region. In an example, the support structure is configured from a thickness of metal material. In an example, the support structure is configured in an upright manner, and has a major plane region. In an example, the assembly has a pivot device configured on the support structure and a torque tube suspending on the pivot device and aligned within an opening of the support and configured to be normal to the plane region. In an example, the torque tube is configured on the pivot device to move about an arc in a first direction or in a second direction such that the first direction is in a direction opposite to the second direction.
