A horizontal solar tracker (1) with a configuration that ensures the transmission of the turning movement generated by the drive element to the rotating beam and to the connecting rod-crank mechanism, prevents possible breaks and weaknesses in the joining areas, and is easy to transport. It comprises at least one front rotating beam (3) and at least one rear rotating beam (12) that can turn, joined by means of a connecting rod-crank mechanism (4). A drive assembly (2) generates the turning movement in a mobile element (22). The front rotating beam (3) has a first joining sector (31) that can be coupled to the mobile element (22) and the connecting rod-crank mechanism (4) comprises a tubular portion (42) that clasps the rotating beam (3) and a second joining sector (43) that can be coupled to the mobile element (22).

A two-piece truss leg system for an A-frame-shaped truss foundation system for single-axis trackers. A driving coupler at the head of each screw anchor used to drive the component into the ground as well as to join the upper leg component to the screw anchor. A connecting portion of the coupler extending above a main body of the coupler is received within an open end of an upper leg component. A curved outer surface of the connecting portion enables the upper leg component to be angularly adjusted relative to the screw anchor. A channel in the connecting portions enables the upper leg component to be deformed into the channel with a crimp connecting.

A solar module mounting bracket system including a plurality of solar modules including mounting slots formed in a sidewall of the solar module, a torque tube configured to support the solar modules such that they can be rotated, a plurality of mounting brackets configured for integration with the torque tube and to which the plurality of solar modules are mounted, at least one first retainer assembly connected to one of the plurality of mounting brackets, the first retainer assembly including a through bolt, a spring, a mounting tab, and nut. When a solar module is placed on the mounting bracket and supported by the torque tube the mounting tab retainer assembly is received in the mounting slot of the solar module.

A rotating support device for a torsion beam is be coupled to a support pillar, especially applicable in solar power plant installations which reduces the number of parts used and facilitates the assembly. The device has a clamp which can be coupled to the support pillar having a cylindrical inner area, a bushing intended to be positioned inside the clamp and which has the possibility of rotation together with the torsion beam with respect to the clamp and a retaining part which can be coupled in the slop which in an assembly situation protrudes in height with respect to the central sector of the clamp.

A driveline joint may include a driveline shaft that has a plurality of slots and a shaft coupling positioned in an interior of the driveline shaft in which the shaft coupling includes one or more openings with each of the openings corresponding to one or more respective slots of the plurality of slots included in the driveline shaft. The driveline joint may include one or more spherical bearings that are each positioned between an interior lateral surface of the driveline shaft and an exterior lateral surface of the shaft coupling and against one of the openings of the shaft coupling. The driveline joint may include one or more fasteners, wherein each of the fasteners extends through one of the slots and one of the openings of the shaft coupling.

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.

An A-frame-shaped truss foundation system for a single-axis tracker with a bearing assembly sitting atop a pair of adjacent angled truss legs joined together with an adapter so that the axis of rotation of the tracker is aligned with a work point of the A-frame. Several such foundation systems are arranged along a North-South row to support a tracker torque tube.

A bearing assembly of a power generation structure including, a rail; and a housing adapted to support the rail; where the housing includes a fixed housing portion attached to a support beam, and an adjustable housing portion attached to rail, where a low friction material is present at an interface between an exterior surface of rail and an interior surface of the adjustable housing portion, where the adjustable housing portion is capable of self-aligning adjustment of at least a portion of the rail out of alignment with a central axis of the support beam.

A solar tracker with orientable solar panels arranged in rows, having at least two rows of photovoltaic modules (1) carrying the solar panels (2), arranged on pillars (6), the solar panels (2) mounted on respective rotation axes (3) longitudinally associated with each other by rotation transmission (5), driven by at least one motor (4) establishing the movement of all the solar panels (2) from a single actuation point, the rows of photovoltaic modules (1) related to each other by at least one transmission bar (7), joined by universal joints (8), to respective rotation transmission (5), the drive motor (4) is coupled in longitudinal alignment with respect to a transverse transmission (12) that meshes with a rotation transmission (5) and with respect to which the universal joint (8) of one end of the corresponding transmission bar (7) is joined in longitudinal alignment on the other side.
