Abstract: A power converter converts a medium-voltage output from a solar module to an appropriate voltage to power a solar tracker system. The power converter includes a voltage divider having at least two legs, a first semiconductor switch subassembly coupled in parallel with a first leg of the voltage divider, and a second semiconductor switch subassembly coupled in parallel with a second leg of the voltage divider. The power converter may be a unidirectional or a bidirectional power converter. In implementations, the signals for driving the semiconductor switches of the first and second semiconductor switch subassemblies may be shifted out of phase from each other. In implementations, if the bus voltages to the semiconductor switches are not balanced, the pulse width of the driving signal of the semiconductor switch supplied with the higher bus voltage is decreased for at least one cycle.

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: A solar tracking system is provided and includes a solar array, a support structure configured to support the solar array, a base configured to rotatably support the support structure, and an articulation system configured to articulate the support structure relative to the base. The articulation system includes a gearbox that is coupled to the support structure and an actuator that is configured to extend and retract. The actuator includes a first end portion and a second, opposite end portion, wherein the first end portion is rotatably coupled to the base and the second end portion is coupled to the gearbox. Extension of the actuator causes the support structure to rotate about the base in a first direction and retraction of the actuator causes the support structure to rotate about the based in a second, opposite direction.

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: Methods and systems of managing dynamic response to wind in a solar tracker system are provided. The method includes determining a wind speed, comparing the wind speed to a predetermined threshold value to determine if the wind speed equals or exceeds the predetermined threshold, positioning a windward most solar tracker to a predetermined angle based on the comparing, and positioning a leeward most solar tracker to the predetermined angle based on the comparing. The solar trackers are positioned at the predetermined angle at a predetermined interval starting at the windward most solar tracker and the remaining solar trackers remain in a normal operating condition.
