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...

What makes you think that cooling can't occur on BOTH of the Uni-Solar surfaces?
One being the upper surface that's exposed to the air and the other being the surface that's adhesively attached to the roof - assuming that the adhesive is, or can be, of a heat conductive type? I'll bet that the lower surface attached to the roof is a better heat conductor than the Uni-Solar's upper surface that is exposed to only air.
(The above "bet" on my part is assuming your roof is white! A dark roof will HEAT the backside of the Uni-Solar panel.)
