Compelling analysis. But if hail damage is the primary concern, tracking seems like an X/Y solution. What about eg anti hail netting that can be rolled out when the weather forecast predicts hail? It seems to me like a middle ground might be automated deployment of hail protection, which by definition has lower aero loading than what amounts to a big semiconductor sail.
i used standard chain link fence on top of my small greenhouse and it works even with such big "holes", no mechanism, just manual labor but needs good forecast which can be issue.
anti-hail netting? you must not be from somewhere that receives a lot of hail. hail punches through solid coverings at the right size. if it's not the right size, then it's not that damaging.
netting? ha! thanks for the funny visual so early in the morning.
