They go as low as 10°C as the ambient temperature, and you can see that in the range they're testing, operation at lower temperature is always more efficient than at higher temperatures.
> we don't even build parks in areas that go above 20-25 degrees if there are no outside incentives
I'm not sure this is actually true.
Here in Germany, we have a lot of cloud cover, and PV parks still make sense economically. I'm pretty sure places with lower cloud coverage, lower land prices but higher temperatures still make PV parks viable.
