Single axis utility scale solar usually has the capability to adjust tilt to vertical when hail is forecasted to minimize kinetic damage. Cannot speak to why that did not occur here.
> Select a tracker system that can engage in a "hail stow" mode. This stow position is typically the maximum vertical tilt the tracker system allows, which should decrease the angle of impact of most hail balls. It’s better if this automatically engages, but some systems are manually operated. Without implementing special design considerations as discussed in (Reznikov 2018), tracker systems may not fare as well in high wind regions, so certain locations may need to balance these conflicting design considerations.
