Solar tracker systems include a torque tube, a column supporting the torque tube, a solar panel attached to the torque tube, and a damper assembly. The damper assembly includes an outer shell surrounding an inner shell. A piston is at least partially positioned within the inner shell and moveable relative thereto. An active lock of the damper assembly includes a housing positioned within the outer shell. The housing defines a cavity and a housing channel extending from the cavity to an outer fluid channel. A shaft extends into the cavity and a valve assembly is attached to the shaft. The shaft is rotatable within the cavity between an unsealed position in which the housing channel is in fluid communication with the cavity, and a sealed position in which the valve assembly is rotationally aligned with the housing channel and obstructs fluid communication between the cavity and the housing channel.

A system and method for fastening protective barriers to solar panel systems includes a fastener system including a main clip that is coupled to a support clip and a wireform splice. The main clip and support clip of the fastener system are adapted to engage with a solar panel frame. Once engaged with the panel frame, a barrier, such as wire mesh, is placed adjacent to a front face of the main clip and the wireform splice may be coupled to the main clip and engaged with the barrier. The splice is used to secure the barrier to the faceplate. In one embodiment, the fastening devices may be placed in a spaced arrangement, and the barrier is coupled to each fastening device along the continuous run. In this way, a single section of barrier may be secured to the solar panel array system.

A photovoltaic support includes a first vertical upright column (110) and a second vertical upright column (120) on a foundation, and a beam (10) respectively hinged with a first end of the first vertical upright column (110) and a first end of the second vertical upright column (120). The photovoltaic support further includes a first movable connecting piece (140) provided on the foundation and connected with a second end of the first vertical upright column (110). The first movable connecting piece (140) is automatically adjusted according to the wind intensity, such that the first vertical upright column (110) moves in a vertical direction to adjust an inclination angle of the beam (130). The photovoltaic support can adjust the angle adaptively in the case of a strong wind, and restore automatically after the strong wind has passed.

Solar tracker systems include a torque tube, a column supporting the torque tube, a solar panel attached to the torque tube, and a damper assembly. The damper assembly includes an outer shell surrounding an inner shell and defining an outer fluid channel. A piston is positioned within the inner shell and moveable relative thereto. A locking valve of the damper assembly includes a shaft extending into a chamber and a seal attached to the shaft. The shaft is selectively moveable axially within the chamber along an extension axis between an unsealed position in which the seal is spaced from a chamber wall and a flow path is defined that extends from within the inner shell, through the chamber, and to the outer fluid channel, and a sealed position in which the seal contacts the chamber wall and the locking valve obstructs the flow path.

A solar concentrating system and installation has a plurality of solar collectors configured for receiving, reflecting, and concentrating radiation in a focal point. The solar concentrating system and installation increases the efficiency of current solar concentrating systems, such as those based on linear Fresnel collectors, by reducing focal distances and increasing the effective surface of the system.

A pump (2) system includes a pump, a sensor (22; 28) arranged in or at a flow path (14), and a concentration measurement device measuring a concentration in liquid inside the flow path (14). The concentration measurement device includes the sensor (22; 28), as a concentration sensor, connected to an evaluation device (26) for evaluating readings of the sensor (22; 28). The evaluation device (26) is connected to a further signal source (20; 24), providing at least one further parameter, and is configured to carry out an evaluation of the reading of the sensor (22; 28), taking into account the further parameter provided by the further signal source (20, 24) to output the concentration in the liquid. A solar heating system includes the pump system.

A damper assembly for single-axis tracker supported by truss foundations. Truss leg damper brackets are attached to each truss leg and provide a fixed mounting point for the lower end of a damper spring. Different techniques may be used to effect mechanical engagement between the leg bracket and truss leg to prevent movement under load. Aligning each damper spring with a truss leg may eliminate moments that must ordinarily be resisted when damper springs are attached to a monopile foundation.

A solar tracker assembly comprises a support column, a torsion beam connected to the support column, a mounting mechanism attached to the torsion beam, a drive system connected to the torsion beam, and a torsion limiter connected to an output of the drive system. When an external force causes a level of torsion on the drive system to exceed a pre-set limit the torsion limiter facilitates rotational movement of the solar tracker assembly in the direction of the torsion, thereby allowing the external force to rotate about a pivot axis extending through the torsion beam. Exemplary embodiments also include methods of aligning a plurality of rows of solar trackers.
