Abstract: A solar tracking system including a plurality of bases, a torque tube supported by the plurality of bases and configured to support a plurality of solar modules, and a drive device operably connected to the torque tube and arranged to translate the torque tube in a direction parallel to its longitudinal axis. The solar tracking system also includes a plurality of helical guides operably connected to the torque tube, and a plurality of cam assemblies, wherein upon linear movement of the torque tube, interaction between the helical guides and cam assemblies causes the torque tube to rotate about its linear axis.

Abstract: A method for controlling the orientation of a single-axis solar tracker orientable about an axis of rotation, the method repetitively completing successive control phases, where each control phase implements the following successive steps: observing the cloud coverage above the solar tracker; 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; matching the observed cloud coverage with a cloud coverage model; servo-controlling the orientation of the solar tracker by applying the orientation setpoint value associated to said cloud coverage model retained during step c).

Abstract: A solar module mounting bracket assembly includes a rail configured to support a solar module thereon, and a pair of braces. The braces each have a first end portion movably coupled to the rail. The braces are movable relative to the rail between a collapsed configuration and an expanded configuration. In the expanded configuration, the braces cooperatively define a channel dimensioned for receipt of a frame member.

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.

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.
