Abstract: A coupling system for solar trackers is disclosed. The coupling system can reduce the number of fasteners and labor required for securing solar modules to torque tubes. The system includes a support rail, a strap assembly, and a fastening assembly. The support rail features an upper surface for receiving solar modules and a lower surface with spaced protuberances forming a gap to accommodate a torque tube. Inner surfaces of the protuberances can inhibit rotation of the torque tube relative to the support rail. The fastening assembly includes retaining bolts with adjustable gaps to secure solar modules of varying thicknesses. Spring arms and biasing elements enhance module retention and alignment. The strap assembly clamps the support rail to the torque tube which can ensure stability.

Abstract: A coupling for use with a solar tracker including an upper portion and a lower portion, the upper portion including a generally tubular body including one or more stamped end portions and the lower portion designed to secure the upper portion to a support rail of a solar power system.

Abstract: A clamp assembly for use with a solar module includes a first clamping arm operably coupled to a first portion of a solar module, a second clamping arm operably coupled to a second portion of the solar module and operably coupled to the first clamping arm and disposed in juxtaposed relation thereto, and a fastener operably coupled to a respective portion of each of the first and second clamping arms. The fastener is configured to draw each of the first and second clamping arms towards one another from a first, open position, where the solar module is free to move relative to first and second clamping arms to a second, closed position, where the solar module is inhibited from moving relative to the first and second clamping arms.

Abstract: A coupling system for use with a solar tracker includes a support rail defining a channel for receipt of a solar module therein, the support rail including an aperture defined therein that is in open communication with the channel and a clamp assembly selectively coupled to the support rail, a first portion of the clamp assembly configured to receive a portion of a torque tube therein and a second portion of the clamp assembly configured to selectively extend through the aperture of the support rail when the clamp assembly is transitioned from a first, unlocked position, to a second, locked position.

Abstract: A pier for a solar tracking system includes a bearing housing assembly, a frame, the frame defining an A-profile having a pair of legs and a crown at a center portion thereof, and a mounting bracket, the mounting bracket coupled to a portion of the crown of the frame at a first portion thereof and coupled to a portion of the bearing housing assembly at a second portion thereof.

Abstract: Coupling assemblies for use with solar trackers include a housing, a bearing, and at least one hard stop. The housing includes a circular aperture and protruding members extending from the housing. The bearing fits within the circular aperture and rotate within the circular aperture of the housing. The bearing includes an aperture having the shape of the cross-section of a torque tube. The hard stop engages with the protruding members to limit rotation of the bearing and torque tube to a preconfigured articulation range. The housing may include opposing ball bearing paths disposed along an inner surface of the circular aperture, and hard stops at end portions of the opposing ball bearing paths. The bearing may include ball bearing races in an outer portion of the bearing. The coupling assembly may include ball bearings configured to move in the ball bearing paths and the ball bearing races.

Abstract: A solar tracker system including at least two solar trackers arranged substantially in parallel, each solar tracker including a torque tube and a plurality of piers supporting the torque tube, a drive mechanism mounted on one of the plurality of piers associated with a first of the at least two solar trackers to rotate the first of the at least two solar trackers, a pulley mounted on each torque tube of the at least two solar trackers, and a cable connecting the pulley of the first of the at least two solar trackers to the pulley of a second of the at least two solar trackers, wherein rotation of the first of the at least two solar trackers is translated to the second of the at least two solar trackers via the cable.

Abstract: An autonomous cleaning system bridge includes a pair of parallel beams and a pair of transverse beam assemblies interposed between the pair of parallel beams and disposed in spaced relation to one another. Each transverse beam assembly includes an outer tube extending between a first end portion coupled to a first parallel beam and an opposite, second end portion, an insert coupled to the second end portion and defining a through-bore, and an inner tube extending between a first end portion and an opposite, second end portion, the second end portion of the inner tube coupled to a second parallel beam, wherein the inner tube is slidably supported within the through-bore to enable to autonomous cleaning system bridge to transition from a first, expanded configuration to a second, collapsed configuration due to contact between the second parallel beam and a portion of a solar tracker system.
