In an example, the present invention provides a solar tracker apparatus. In an example, the apparatus comprises a center of mass with an adjustable hanger assembly configured with a clam shell clamp assembly on the adjustable hanger assembly and a cylindrical torque tube comprising a plurality of torque tubes configured together in a continuous length from a first end to a second end such that the center of mass is aligned with a center of rotation of the cylindrical torque tubes to reduce a load of a drive motor operably coupled to the cylindrical torque tube. Further details of the present example, among others, can be found throughout the present specification and more particularly below.

A solar power system can include a rail and a solar module disposed on the rail. A clamp assembly can couple the solar module to the rail. The clamp assembly can have a clamped configuration in which the solar module is secured to the rail and an unclamped configuration. The clamp assembly can comprise an upper clamp member, a lower clamp member coupled to the rail, and a stabilization member mechanically engaging the upper clamp member and the lower clamp member. The stabilization member can prevent rotation of the lower clamp member relative to the rail when the clamp assembly is in the clamped and unclamped configurations. In the unclamped configuration, the stabilization member can be biased such that the upper clamp member is disposed at a sufficient clearance above the rail to permit the insertion of the solar module between the upper clamp member and the rail.

An adjustment fitting for fastening a solar panel carrier rail to a post profile that is anchored to the ground, includes a foot segment, a head segment and an adjustment element. The foot segment has a first mounting flange and includes a fastening portion, which extends away from the mounting flange on one side of the first mounting flange and is used to fasten the foot segment to the post profile. The head segment includes a second mounting flange for bearing the head segment and fastening it to the first mounting flange of the foot segment, which can be inserted into the carrier rail in portions and includes an elongate hole in two side walls that are arranged opposite one another. The adjustment element, which is arranged between the two side walls of the head segment, can be locked in different latching positions on the head segment.

A truss foundation for single-axis trackers that is optimized to resist moments. For foundations that experience lateral loads as well as moments, the foundation supports the rotational axis via a moment connection that is deliberately offset below the work point to reduce the impact of the bending moment. Spacing between the truss legs and the angle of the legs impact the height of the truss work point and, by extension, the available offset below the work point down to the minimum height of the axis of rotation specified by the tracker maker.

A single-axis tracker supported by multiple A-frame-shaped single-truss foundations that translate lateral loads into axial forces of tension and compression, and at least one truss foundation supporting the torque tube drive motor or other tracker component subject to axial loads to provide support for lateral loads as well as loads oriented along the axis of the torque tube.

A coupler for joining truss leg components provides angular adjustability between the respective axis of the leg components. A prolate spheroid-shaped coupler with three channels circumscribing its surface enables the upper leg components to compensate for axial misalignment of driven screw anchors in all directions. A hydraulic crimping device with upper and lower crimping guides registers its position with features on the truss hardware to insure that blind triple crimps are performed consistently each time.

In an example, the solar tracker has a clamp assembly configured to pivot a torque tube. In an example, the assembly has a support structure configured as a frame having configured by a first and 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, 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.
