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.

A new and innovative hard ceramic coating having refractory properties is provided. The ceramic coating may be used as a replacement for refractory materials. As opposed to polymer-based coatings that are sacrificial when exposed to extreme temperatures, the ceramic coating is a non-sacrificial, fully inorganic (e.g., free of organic components) coating that resists many thermal cycles. The ceramic coating is also thinner and lighter than conventional refractory materials the ceramic coating can replace. The ceramic coating demonstrates advantageous thermal insulation properties (e.g., low thermal conductivity) over a wide range of temperatures and when applied with minimal thickness. The ceramic coating also demonstrates high emissivity, low thermal conductivity, and high resistance mechanical properties, which are all desirable properties for use as a thermally insulating replacement coating for refractory materials.
