Tech ingredients did a test with active cooling on standard solar panels and found the energy to cool it was about what was gained by having a cooler panel.
The upshot should be longer life if the panel though, so the conclusion was still a net gain.
These guys are the ones who went to burning man when they were young and it was cool, but kept going, got old, and ruined it for the next generations.
Makes me sad as a member of the Oregon Gen who missed the heydays of that kind of stuff, but read all about it as it was in its prime.
