Abstract: 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.

Abstract: 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.

Abstract: 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.
