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. 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.

Abstract: In an example, the present invention provides a solar tracker apparatus configured with an off-set drive assembly. In an example, the apparatus has an inner race structure, which has a cylindrical region coupled to a main body region, the main body comprising an off-set open region. The cylindrical region is an annular sleeve structure coupled to the main body region, which occupies the spatial region within the cylindrical region. In an example, the apparatus has an outer race structure coupled to enclose the inner race structure, configured to couple the inner race structure to allow the inner race structure to move in a rotational manner about a spatial arc region; and configured to allow the inner race structure to pivot about a region normal to a direction of the spatial arc region. In an example, the solar tracker has a clamp assembly that is configured to pivot a torque tube.

Abstract: A bifacial solar module with enhanced power output including first and second transparent support layers, a plurality of electrically interconnected bifacial solar cells arranged between the transparent support layers with gaps between one or more of the interconnected solar cells and edges of the first and second transparent support layers, the bifacial solar cells having a first side directly exposed to solar radiation and a second side opposite the first. The bifacial solar module further includes one or more micro-structured reflective tapes positioned coincidentally with the gaps and attached to a surface of the second support layer such that light passing through the second support layer is reflected back into the second support layer at angles such that light reflecting from the tape is absorbed by either the first or second side of the bifacial solar cells.
