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: A method for installing one or more solar module A-frame supports includes: creating a bore extending a depth below a ground surface, placing a temporary support jig adjacent the bore, inserting a leg of a solar module A-frame support into the bore such that a portion of the leg of the solar module A-frame support is within the bore and a portion of the leg of the solar module A-frame support contacts the temporary support jig, when the portion of the leg of the solar module A-frame support is within the bore and the portion of the leg of the solar module A-frame support contacts the temporary support jig, pouring concrete into the bore, and, after pouring concrete into the bore, removing the temporary support jig from contact with the leg of the solar module A-frame support.

Abstract: A solar tracker includes a plurality of piers, one end of the piers configured for installation in the earth, a plurality of bearings, each bearing supported by a pier, a torque tube received in the plurality of bearings and configured to support a plurality of solar modules, a plurality of drive motors, each drive motor associated with a pier, a plurality of high efficiency gear boxes, each high efficiency gear box associated with one of the plurality of drive motors; and a plurality of brakes, each brake associated with one of the plurality of high efficiency gear boxes and one of the plurality of drive motors, wherein in combination the plurality of brakes apply sufficient braking force to prevent back driving of the torque tube.

Abstract: A docking station for use with a solar tracking system includes a frame configured to selectively support solar cleaning equipment thereon and a mounting bracket operably coupled to a portion of the frame. The mounting bracket maintains a gap between adjacent edges of the frame and an adjacent solar module, and the frame includes a width that approximates a width of the solar module.
