Abstract: 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.

Abstract: 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.

Abstract: A method for controlling the orientation of a single-axis solar tracker (1) orientable about an axis of rotation (A), said method repetitively completing successive control phases, where each control phase implements the following successive steps:



a) observing the cloud coverage above the solar tracker (1);
b) comparing the observed cloud coverage with cloud coverage models stored in a database, each cloud coverage model being associated to an orientation setpoint value of the solar tracker;
c) matching the observed cloud coverage with a cloud coverage model;
d) servo-controlling the orientation of the solar tracker by applying the orientation setpoint value associated to said cloud coverage model retained during step c).




The present invention finds application in the field of solar trackers.

Abstract: Methods and systems of managing dynamic response to wind in a solar tracker system are provided. The method includes determining a wind speed, comparing the wind speed to a predetermined threshold value to determine if the wind speed equals or exceeds the predetermined threshold, positioning a windward most solar tracker to a predetermined angle based on the comparing, and positioning a leeward most solar tracker to the predetermined angle based on the comparing. The solar trackers are positioned at the predetermined angle at a predetermined interval starting at the windward most solar tracker and the remaining solar trackers remain in a normal operating condition.

Abstract: A solar tracking system is provided and includes a solar array, a support structure configured to support the solar array, a base configured to rotatably support the support structure, and an articulation system configured to articulate the support structure relative to the base. The articulation system includes a gearbox that is coupled to the support structure and an actuator that is configured to extend and retract. The actuator includes a first end portion and a second, opposite end portion, wherein the first end portion is rotatably coupled to the base and the second end portion is coupled to the gearbox. Extension of the actuator causes the support structure to rotate about the base in a first direction and retraction of the actuator causes the support structure to rotate about the based in a second, opposite direction.
