Reply To: Solar Panel “Farm” and astronomical seeing

I agree with James. The internet suggests solar farms can reach ~50C on a summer afternoon, which I imagine would have a significant effect on day-time seeing on sunny days. But I agree with James that their thermal inertia is likely to be quite low, so I would expect the panels to cool off quickly at dusk and pose little problem. But in the absence of empirical data, that’s just my guess!
