Resumen de: US2025379545A1
Stowing flexible tracker systems with the panel surfaces at a negative tilt angle during high wind is enhanced through optimizing around total system damping in order to address aerodynamic instabilities. Current flexible tracker designs function by avoiding the regions in which negative aerodynamic damping primarily occurs. Doing so requires them to stow at maximum absolute tilts to remain stable. However, methods disclosed here select system flexibility, system mechanical damping, and tracker stow angles to achieve a positive aerodynamic damping function and thus enable stable wind stow at lower than maximum tilt angles. The design approach addresses multiple current failure modes within the PV tracker industry while reducing installation cost relative to current designs.
