As you clearly have some idea let me ask what do you think will happen when nuclear is out and outside temperature is closer to 45°C than 40°C.

I’m not familiar with commercial solar panels. Do those need cooling? Residental probably don’t have it anyway?

So no problems with efficiency and coating still not starting to degrade and electronics survived it well? What do you consider heatwave? If your system records the temperature / panel inner temperature and production data it would be interesting to see. I’m especially interested in the data from france and spain in the times of extreme heat (close to when the fires happened).

Not so funny thing is that the solar power (at least panels as far as I know) doesn’t work well either if the weather is really hot.
