More Solar for "Us"
Ok, I went off.the deep end? Bought 3 used 37watt uni-solar panels and a blue sky 2000e controller for the hefty price of $400, They were being listed as 75w panels, they are not The tested open...

Hi Salvo,
Ah, but they do and will radiate. Just hook up a standard panel with no diode--it will radiate at night just fine, while draining the battery.
I suggest you research Uni-Solar panels documented claims about heat tolerance. I did before I purchased mine.
And metal is an even better conductor of heat than glass. The Unisolar panels that Mr. Wizard and I both have are deposited directly on the metal panel. It does radiate heat. My panels are not flush to the roof as the roof is curved.
But this is all way off topic. So to lighten the the discussion here is something wonderfully funny:
1st and 2nd Laws of Thermodynamics

No, I didn't misunderstand you. I suggest you get a grip on thermodynamics before providing misinformation.
1. The panels do not RADIATE heat. Heat transfer is through CONDUCTION.
2. Glass is a pretty good thermal conductor. It's 100 times better conductor than air. It's conductivity is similar to thermal grease.
3. Since all the heat needs to be conducted to air, air is the weakest link in the equation. The surface area of the panel that makes contact to air is the dominate factor in keeping the panel cool.
