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).
South of Germany here. We had temperatures up to 40°C and the system on the roof did fine. You can also see stats about german energy production here, there is no broad failures on hot days
They lose a bit in efficiency, yes. On the other hand there is usually not much of a cloudy weather when it’s that hot either. Solar panels still work more efficiently and deliver more electricity under these conditions than most other forms of power generation.
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.
This is borderline fake news - I can confirm that the system on my roof worked during the heatwaves without any problem.

A quick google will tell you what it means… 0,3-0,5% efficiency reduction per 1°C over 25°C panel temperature.
That equates to 10% less power output when the panels are at 60°C for example.

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?
