Azimuthal rotation mechanism for solar trackers comprising a vertical pedestal (1) on which a rotating support (2) holding the solar panels (7) is mounted, which is actuated by means of at least three hydraulic cylinders (4, 5 and 6) located in the same horizontal plane and articulated through the casing to the rotating support (2) by means of a first movable vertical shaft (18), while the piston rods of the three cylinders pass through the wall of the rotating support and are articulated at the same height to the pedestal by means of a second fixed vertical rotation shaft (21).

A movement control apparatus for a heliostat device may include a step motor, a decelerating motor, a ball screw assembly, a nut, a connecting shaft, and a linear moving shaft. In one embodiment, the nut is movably connected with the ball screw assembly and is secured on a first connecting board and a second connecting board through the connecting shaft. The nut is driven by the ball screw assembly to travel along the screw shaft and since the nut is connected to the connecting boards through the connecting shaft, and the connecting boards are connected to the moving shaft, the movement of the nut can further drive the connecting shaft to rotate to drive the moving shaft to move in a linear manner on the sliding rail to rotate a mirror assembly of the heliostat around a post.

A solar module comprising at least a plurality of lamellar solar panels, which are mounted pivotably, about a common axis, on an elongate support and can be and which can be moved between a first position, in which they are disposed on top of each other substantially congruently and parallel to the support, and a second position, in which they lie substantially next to each other in a fanned out manner about the aforementioned axis, wherein the support can be pivoted out of a housing, which accommodates the support together with the solar panels in the first position of the panels, characterized in that the solar module comprises two supports of the aforementioned type equipped with solar panels in the manner described, wherein the two supports are pivotably hinged at the diametrical longitudinal ends of an elongate base support, which is mounted rotatably, about an approximately vertical axis, in the housing.

A solar tracking system with torsion tubes having solar panels (modules) mounted thereon. Columns support the system and have bearings for rotation of the torsion tubes. A flexible transmission shaft is connected at one end to a mechanical drive mechanism for rotating the torsion tubes and thereby rotating at least an individual row of modules to follow the sun's diurnal motion. The torsion tubes can be rotated in an opposite direction, or backtrack, to prevent shadowing from one individual row of modules to another. The flexible transmission shaft is connected to a single motor at its other end and is constructed of flexible materials to compensate for misalignment due to uneven terrain or staggered row of module configuration. Dampers are also employed and affixed to the row of modules to decouple wind forces imposed on the row of modules.

A floating solar array made of a closed loop of flexible high density polyethylene pipes with elbows, T fittings and couplings. An anti-lift membrane fills with water and mitigates the wind forces. The array can have a stabilizing skirt going downwardly from the border of the array, especially when it is used offshore in the sea. A vertical axis tracking system with windlasses, two anchoring points and four mooring lines allows all the solar panels to face the sun throughout the day. For small lakes or mine tailing, the two anchor points will be onshore, on a concrete foundation. Winches to wind and unwind the mooring lines are located at the anchor point or on the solar array. For larger water areas, or offshore applications in the sea water, the anchor points are under water; using typically a concrete block or a suction pile solution for each anchor.

A solar-powered system includes a mounting assembly to affix a solar active component mounted to a support member by the mounting assembly, such that both sides of the solar active component have solar exposure.

A drone landing system includes a solar collector to charge the drone at a landing cite of the drone landing system. The solar collector may include a solar collector mounting assembly, preferably comprises a bi-facial solar active component mounted with its solar active face(s) orthogonal to the ground/horizon, at or near its perimeter frame.

The element on which solar radiation is concentrated, specifically, a vacuum tube, remain static at all times with respect to the movements that a parabolic reflective surface may make according to the direction of solar radiation, such that inlet and outlet pipes of the vacuum tube do not need to be articulated, which facilitates the installation and insulation thereof and reduces production costs. The parabolic reflective surface can pivot 360 with respect to the vacuum tube without interfering with the pipes, allowing an active safety system for protecting against strong winds and preventing overheating to be produced, in addition to allowing the surfaces to be cleaned by means of nozzles spray pressurized water. The collector also includes passive safety means against strong winds.

A revolving sun-tracking structure includes a base having a center, a first face, a second face opposite the first face, and an outer edge. Affixed to the second face is an axle with first and second ends, and a second axle with third and fourth ends. Wheels are rotationally coupled with the ends, configured for rotation, and one such wheel is a drive wheel. A drive unit is affixed to the second face, wherein the drive unit is rotationally coupled to the drive wheel. Furthermore, the revolving sun-tracking structure includes a solar sensor array attached to the first face along the outer edge of the base, configured to detect solar radiation intensity and communicate electronically with a control unit attached to the second face. Such configuration allows for the base to rotate such that the revolving sun-tracking structure maintains a neutral position relative to solar radiation exposure, maximizing such exposure.
