System and method for flexible solar tracker and testing

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.

20220294387 · 2022-09-15 ·

A method may include obtaining information from a weather forecasting service that relates to indicators of an incoming hail event. The method may include determining a stowing score that quantifies whether the hail event is likely to occur within a period of time based on the information from the weather forecasting service. Responsive to the stowing score exceeding a threshold value, a time at which the incoming hail event is likely to occur may be predicted based on the weather forecasting service information. The threshold value may indicate a threshold likelihood of the hail event occurring or a threshold period of time before occurrence. The method may include determining a wind direction at the predicted time at which the hail event is likely to occur and stowing photovoltaic modules based on the wind direction.

Adaptive stow for solar tracker systems

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.
