摘要： 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.

摘要： 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. The DCBCs manage charge and discharge of the batteries, enable the interconnection of the PV arrays and the batteries, and supply a constant medium voltage to the central inverter.
