The first integral grounding device is configured to electrically bond a frame of an electricity generating device to the mounting bracket assembly. The mounting bracket assembly may further include a second integral grounding device configured to electrically bond a torque tube to the mounting bracket assembly.

Torque limiter devices, systems and methods and solar trackers incorporating torque limiters
A solar tracker assembly comprises a support column, a torsion beam connected to the support column, a mounting mechanism attached to the torsion beam, a drive system connected to the torsion beam, and a torsion limiter connected to an output of the drive system. When an external force causes a level of torsion on the drive system to exceed a pre-set limit the torsion limiter facilitates rotational movement of the solar tracker assembly in the direction of the torsion, thereby allowing the external force to rotate about a pivot axis extending through the torsion beam. Exemplary embodiments also include methods of aligning a plurality of rows of solar trackers.

A mounting bracket assembly comprises a flexible body including at least one top member and a flexible angled bottom member connected to the top member. The flexible body defines a beam insertion aperture between the top member and the bottom member. The mounting bracket assembly further comprises at least one clamp attached to the top member. The mounting bracket assembly may further comprise a threaded rod running through the at least one top member and a clamping nut securing the threaded rod to the top member such that rotating the clamping nut compresses the top member and grounds an electricity generating device such as a photovoltaic module. The mounting bracket assembly may further comprise an integral grounding device disposed adjacent the top member to electrically ground the electricity generating device.
A solar tracking system with a torque tube supporting solar panels. Columns support the system and have bearings for rotation of the torque tube. A drive is coupled to the torque tube and is driven by a gearbox, such as a worm gear assembly, for rotating the array of solar panels to follow the sun's diurnal motion. The array can rotate in an opposite direction, or backtrack, to prevent shadowing from one module row to another. Multiple gearboxes can be mechanically linked by drive shafts and driven by a single motor. The drive shafts may incorporate universal joints for uneven terrain or staggered configurations. Harmonic dampers can be affixed to the solar panels to decouple wind forces which allows the use of larger solar panels.
