A system for fastening a casing to a tube which, according to a first aspect of the invention, includes a claw provided with protuberances, and, according to a second aspect of the invention, comprises an incorporation of first rails on side faces of the casing, and second rails on an upper face of the casing to hook onto the protuberances. The claw can pivot with respect to the first protuberances, both to house the tube and to hook onto the second rail, as well as to surround and press against the tube, once the second rail is hooked. The fastening system allows for a faster and more ergonomic fastening without the use of tools and elements such as connecting screws and bolts.

A plurality of posts and actuator posts connected to a foundation and to a torque tube on which solar panels are duly mounted is disclosed. The actuator posts include a hinge next to a radial arm that is disposed solidly connected to the torque tube, the arm being hinged at the other end to a linear actuator with screw drive, the bottom end is connected to the actuator post by a joint. Each linear actuator is actuated by a gear that engages with an endless screw solidly connected to a Cardan-type drive shared by all the actuators and is actuated by an electric motor, the Cardan-type drive fitting closely to the torque tube by supports.

A method may include positioning one or more PV module mounting devices along a length of a structural component. The method may include specifying one or more parameters related to fastening the PV module mounting devices to the structural component, the one or more parameters indicating a spacing between the PV module mounting devices. The method may include fastening, by an automated attachment equipment, the PV module mounting devices to the structural component based on the specified parameters and moving the PV module mounting devices fastened to the structural component to an assembly platform.

A system for mounting roof tiles, such as solar tiles 108, is disclosed. The system includes a plurality of base mounting sections 200, a plurality of pin joint 102 and a plurality of overhang sections 104. The base mounting sections are fixed to deck 302 horizontally in spaced disposition parallel to a deck ridge 304, and the pin joints 102 and the overhang sections 104 are fixed to two proximal and distal sides of tiles 108 by adhesives. The tiles 108 are removably installed over a pair of adjacent base mounting sections 200 with the overhang section 104 fastened to the proximal base mounting section 200 and the pin joints 102 fastened to the distal base mounting section 200. After installation, the overhang section 104 overlaps with the tiles 108 of adjacent row on the proximal side thereby preventing ingress of water.

Systems and methods for providing and controlling solar panel arrays are provided. The solar panel array may include one or more articulating joints that may provide variability in the arrangement of solar panels, which may allow the solar panel array to be distributed over varying types of underlying surfaces. The articulating joints may allow orientations of solar panels to be different relative to one another. The articulating joints may convey rotational force across the joints, so that a rotational force used to drive a first solar panel may also be conveyed across the joint and used to drive a second solar panel. The controls system may include row-specific semi-autonomous, or autonomous, controllers as well as controllers to interface with multiple rows. The controllers may include sensors to measure system power generation and basic operations aspects of the solar field to directly measure, or infer, module shading within the solar field. The controller may use this shading and operations data to identify shading, mitigate shading, identify methods to increase power generation, and identify optimum tilt angles for the tracker rows.

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

A mounting assembly for use in mid-grab and/or edge-grab applications may include a clamp secured to a stanchion by a clamping fastener. The mounting assembly may also include a mounting plate which may be secured to a mounting device by the stanchion. The mounting assembly may be used, for example, to secure photovoltaic modules (or other devices or structures) of varying heights to a roof or other building surface.

An alignment and installation jig for a screw anchor driving machine. The alignment and installation jig includes a laser target that can be moved from an alignment position to a driving position. The jig may also include one or more automated crimping assemblies to form permanent connections between overlapping foundation components while the machine is correctly oriented to assembly a truss foundation. One crimping assembly device may effect crimp joints between a foundation component held by the jig and overlapping upper ends of a pair of adjacent foundation legs. Second crimping assemblies may telescope down each leg to effect respective crimp joints between the lower end of the leg and the upper end of a driven foundation component.

A solar tracker system includes a support tube, a solar panel assembly connected to the support tube, and an active lock connected to the support tube. The active lock includes a housing defining a chamber and a seal. The seal prevents a flow of fluid through the chamber when the active lock is in a sealed state and allows the flow of fluid through the chamber when the active lock is in an unsealed state. The active lock further includes a locking system motor connected to the seal to transition the active lock between the sealed state and the unsealed state, a battery providing power to the locking system motor, and an antenna for receiving instructions controlling the locking system motor.

A support for the photovoltaic modules of a solar tracker is provided having simplicity and speed in assembly. Specifically, the modules (1) are limited by a frame (2) intended for supporting a photovoltaic panel, and the tracker is provided with a rotating shaft (3) provided with two side surfaces (4) and an upper surface (5) between the side surfaces (4) and a lower surface (6). The support includes a profiled rail (31) intended for being linked in a manner perpendicular to the rotating shaft (3) and for supporting at least one frame (2) provided with an omega-shaped section, two brackets (12) intended for being located on each side of the rotating shaft (3), respectively, and a flat (18) which can be linked to the two brackets (12), such that the profiled rail (31) is linked to the rotating shaft (3).
