Abstract: A solar tracker system comprising a plurality of on sun trackers and a plurality of off sun tracker. Each tracker is selectively adjusted to achieve a desired power output of the solar power plant system in an example.

Abstract: A solar tracking system is provided and includes a solar array, a plurality of support beams configured to support the solar array, a torque tube coupled to the plurality of support beams, a base configured to rotatably support the torque tube, and an articulation system configured to rotate the torque tube relative to the base. The articulation system includes a first helical tube coupled to the torque tube, a first helical tube support disposed on the base and configured to slidably support the first helical tube, and a gearbox in mechanical communication with the first helical tube. Actuation of the gearbox causes the first helical tube to translate within the first helical tube support and the first helical tube support is configured to rotate the first helical tube as the first helical tube is translated therein to cause a corresponding rotation of the solar array.

Abstract: Systems and methods integrate advanced solar tracker, battery, inverter, and software technologies to improve performance, plant output, and costs. The systems may incorporate an advanced vanadium flow battery (VFB) that is DC-voltage (DV)-coupled to photovoltaic (PV) arrays for high, round-trip efficiency. The systems incorporate a DC architecture that optimizes performance for commercial, industrial, agricultural, and utility applications. A distributed direct current (DC) power system includes a centralized, single-stage inverter; PV arrays; maximum power point tracking (MPPT) converters coupled between the PV arrays and the centralized, single-stage inverter; batteries; and DC-DC battery converters (DCBCs) coupled to the batteries. The MPPT converters maximize solar power production by the PV arrays and minimize mismatch between the PV arrays.

Abstract: In an example, a clamp assembly for a glass on glass solar module for a tracker is included. The assembly has a lower clamp structure characterized by a top-hat shaped rail structure having a length extending from a first end to a second end. In an example, the assembly has an upper clamp structure configured to sandwich a pair of edges of a pair of solar modules with a portion of the lower clamp structure. In an example, the assembly has a locking spacer configured to the pair of edges of the pair of solar modules. In an example, the pair of edges comprises substantially glass material. In an example, the assembly has a pair of key structures configured with the locking spacer. Each of the key structures is affixed to each of the solar modules to physically lock each of the solar modules to the upper clamp structure.

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.
