    Abstract: In an example, the solar tracker has a clamp assembly configured to pivot a torque tube. In an example, the assembly has a support structure configured as a frame having configured by a first and second anchoring region. In an example, the support structure is configured from a thickness of metal material. In an example, the support structure is configured in an upright manner, and has a major plane region. In an example, the assembly has a pivot device configured on the support structure, a torque tube suspending on the pivot device and aligned within an opening of the support, and configured to be normal to the plane region. In an example, the torque tube is configured on the pivot device to move about an arc in a first direction or in a second direction such that the first direction is in a direction opposite to the second direction.

    Abstract: In an example, the present invention provides a solar tracker apparatus. In an example, the apparatus comprises a center of mass with an adjustable hanger assembly configured with a clam shell clamp assembly on the adjustable hanger assembly and a cylindrical torque tube comprising a plurality of torque tubes configured together in a continuous length from a first end to a second end such that the center of mass is aligned with a center of rotation of the cylindrical torque tubes to reduce a load of a drive motor operably coupled to the cylindrical torque tube. Further details of the present example, among others, can be found throughout the present specification and more particularly below.

    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: Solar power systems and methods utilize DC power transmission and centralized power inversion. The solar power systems include a photovoltaic (PV) bus system and a fixed bus system. The PV system utilizes a control mode handoff control method, which includes determining that a local maximum power point tracking (MPPT) control is enabled; in response to determining that the local MPPT control is enabled, starting an MPPT mode timer; performing local MPPT; determining that the MPPT mode timer is greater than a predetermined period; and, in response to determining that the MPPT mode timer is greater than a predetermined period, handing off MPPT control to the next MPPT controller. The distributed MPPT control method may include sequential MPPT control, adaptive ΔV MPPT control, and/or power limiting control. The fixed bus system includes PV string-level MPPT controllers and a fixed DC input central inverter or multiple fixed DC modular inverters.
