Patent number: 11949368Abstract: A photovoltaic system includes a collection of photovoltaic modules, a base supporting the collection of photovoltaic modules, and a damper coupled between the collection of photovoltaic modules and the base. The damper resists movement of the photovoltaic modules relative to the base. The damper has a first damping ratio when the collection of photovoltaic modules moves at a first rate relative to the base and a second damping ratio when the collection of photovoltaic modules moves at a second rate relative to the base, and the damper passively transitions from the first damping ratio to the second damping ratio.Type: GrantFiled: January 27, 2021Date of Patent: April 2, 2024Assignee: FCX Solar LLCInventors: Christopher Thomas Needham, Frank Carl Oudheusden

Patent number: 11774321Abstract: Disclosed herein is a technique of configuring flexible photovoltaic tracker systems with high damping and low angle stow positions. Under dynamic environmental loads implementing a high amount of damping (e.g., greater than 25% of critical damping, greater than 50% of critical damping) or a very high amount of damping (e.g., 100% or greater of critical damping, infinite damping) enables the flexible tracker system to prevent problematic aeroelastic behaviors while positioned in a low stow angle. The disclosed technique is further applied to a prototyping process during wind tunnel testing.Type: GrantFiled: July 6, 2022Date of Patent: October 3, 2023Assignee: FCX Solar LLCInventors: Christopher Thomas Needham, Frank Carl Oudheusden

Patent number: 11422575Abstract: A solar tracker system includes a photovoltaic panel and an actuator coupled to the photovoltaic panel and configured to actuate to rotate the photovoltaic panel around a base. A controller communicatively coupled to the actuator is configured to detect a direction from which wind is incident on the photovoltaic panel. Based on the direction from which wind is incident on the photovoltaic panel, the controller adaptively controls the actuator to set a stow position of the photovoltaic panel.Type: GrantFiled: June 21, 2021Date of Patent: August 23, 2022Assignee: FCX Solar LLCInventors: Christopher Thomas Needham, Frank Carl Oudheusden

Patent number: 9985154Abstract: A solar canopy has a solar panel assembly including a first solar panel coupled to a second solar panel and oriented non-parallel with respect to the second solar panel. The solar panel assembly has an effective solar-panel-assembly wind loading less than a sum of a first-solar-panel effective wind loading and a second-solar-panel effective wind loading determined individually. An actual load applied by the solar panel assembly to a solar-panel-assembly support structure coupled thereto when the solar panel assembly is subject to a wind loading is less than a design load for the solar panel assembly subject to the wind loading based on a sum of a first-solar-panel net pressure and a second-solar-panel net pressure determined independently.Type: GrantFiled: August 31, 2017Date of Patent: May 29, 2018Assignee: FCX SOLAR LLCInventors: Christopher Thomas Needham, Frank Carl Oudheusden
