Patent number: 11955923Abstract: A solar tracker including at least one pair of piers configured to be secured in the ground and defining a span between the pair, a bearing supported on the pier, and a torque tube supported in the bearing such that the bearing enables rotation of the torque tube, the torque tube including a double wall thickness area, wherein the double wall thickness area limits deflection of the torque tube along the span.Type: GrantFiled: August 17, 2021Date of Patent: April 9, 2024Assignee: NEXTRACKER LLCInventors: Ricardo Delgado-Nanez, Jacob Mark Morin, Alexander W. Au, Samuel Heller

Publication number: 20230283226Abstract: 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.Type: ApplicationFiled: May 11, 2023Publication date: September 7, 2023Applicant: Nextracker LLCInventors: David E. Kresse, Samuel Heller
