Just got a private e-mail suggesting that I do "pitch up" the PV panels as it markedly increases air circulation under/around them. By pitching the top part up, just a few inches, hot air exhausts. I am planing three rows of panels so this thought may well have merit.

It was suggested that I put in an extra block under the rail that is at the top part of each panel row. I assume this would be at the bottom of the "L" bracket that fastens to the metal roof and is lag bolted to the roof trusses.

I do know that heat is a major negative for PV panel kW generation.

Pinball, Robaroni? Thoughts?
