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.

Embodiments generally relate to a screening element, screen assembly, and associated fixing systems, components and methods. Such embodiments can be used for exterior protection of windows and/or building facades, particularly in commercial buildings and the like. Some embodiments relate to a lightweight screening element, awning or louvre blade that can be readily fixed and applied to the exterior of buildings or built structures so as to provide a screen. Some embodiments relate to a screening element, comprising: an elongate panel defining a first portion and a second portion angled relative to the first portion; and at least one solar panel connected to the first portion of the elongate panel.

A shading apparatus with panels configured to provide shade volume over time, reduce wind load, and optionally generate solar energy. The shading apparatus with panels has first panel and second panel arrays. The first panel array moves up and down using a ganging assembly and linear actuator. The second panel array is fixed opposite the first panel array. Both panel arrays are connected to a rotateable spindle and central post. The shading apparatus is configured to reduce wind load with offset panels that provide passages between the offsets. Embodiments include control logic with various modes, including a mode for orienting the panels orthogonal to the sun over a period of time.

A one-piece truss adapter for supporting single-axis trackers with truss foundations. A upside-down Y-shaped structure has bearing support portion and an opposing pair of legs with an angularly adjustable connector for securely joining the one-piece adapter to a pair of driven screw anchors at different angular orientations. Each leg terminates in a connector that is received in a socket integral to a driving coupler at the head of each screw anchor. A retaining nut may hold the connector in place to complete the angularly adjustable assembly.

The invention relates to a workshop (18) for the construction of pre-assembled structures for solar trackers, each structure comprising a support beam, at least two stands supporting the beam and each comprising a support cradle, the two cradles being spaced apart by a predetermined inter-cradle distance. The workshop (18) comprises two consecutive assembly zones (Z.sub.1-Z.sub.3), and at least two trolleys (20a, 20b) capable of being moved on the ground, for the construction of a single pre-assembled structure, on rolling tracks (19a, 19b) connecting the zones (Z.sub.1-Z.sub.3) The zones comprise: —an initial assembly zone (Z.sub.1) in which the stands are assembled directly on the trolleys (20a, 20b); and a second assembly zone (Z.sub.2) comprising two locations (23a, 23b) holding the trolleys (20a, 20b) n position for assembly of the support beam onto the cradles while ensuring that the cradles are spaced apart by said predetermined inter-cradle distance.

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.
