    Abstract: In an example, the present invention provides a solar tracker apparatus configured with an off-set drive assembly. In an example, the apparatus has an inner race structure, which has a cylindrical region coupled to a main body region, the main body comprising an off-set open region. The cylindrical region is an annular sleeve structure coupled to the main body region, which occupies the spatial region within the cylindrical region. In an example, the apparatus has an outer race structure coupled to enclose the inner race structure, configured to couple the inner race structure to allow the inner race structure to move in a rotational manner about a spatial arc region; and configured to allow the inner race structure to pivot about a region normal to a direction of the spatial arc region. In an example, the solar tracker has a clamp assembly that is configured to pivot a torque tube.

    Abstract: The present disclosure relates to 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: A solar tracking system includes a solar array, support beams that support the solar array, a torque tube coupled to the support beams, a base that rotatably supports the torque tube, and an articulation system that rotates the torque tube relative to the base. The articulation system includes an outer tube, a screw rod, and a nut and/or inner tube that rotates and translates along a length of the screw rod as the screw rod rotates. The interior portion of the outer tube includes helical grooves and the exterior portion of the nut or inner tube includes ridges or rollers that mate with the helical grooves, which cause the nut and/or inner tube to rotate as the nut and/or inner tube is translated along a length of the screw rod when the screw rod is rotated by the motor.

    Abstract: A solar tracker apparatus includes an adjustable hanger assembly that has a clam shell hanger assembly. The clam shell hanger assembly may hold a torque tube comprising a plurality of torque tubes configured together in a continuous length from a first end to a second end. A center of mass of the solar tracker apparatus may be aligned with a center of rotation of the torque tubes, in order to reduce a load of a drive device operably coupled to the torque tube. Solar modules may be coupled to the torque tubes. The solar tracker includes an energy system that includes solar panel, a DC to DC converter, a battery, and a micro-controller. The energy system may facilitate full operation movement of the tracker apparatus without any external power lines.

    Abstract: A method for controlling the orientation of a single-axis solar tracker (1) orientable about an axis of rotation (A), said method repetitively completing successive control phases, where each control phase implements the following successive steps: a) observing the cloud coverage above the solar tracker (1); b) comparing the observed cloud coverage with cloud coverage models stored in a database, each cloud coverage model being associated to an orientation setpoint value of the solar tracker; c) matching the observed cloud coverage with a cloud coverage model; d) servo-controlling the orientation of the solar tracker by applying the orientation setpoint value associated to said cloud coverage model retained during step c). The present invention finds application in the field of solar trackers.
