Possible? Thermal Shade Effect? Panels On Roof?
Has anyone out there plastered solar panels all over their roof and noticed a marked difference in ceiling heating? A difference maybe felt by the hand?

My fiberglass roof is white and thin.
I added 1/2 inch foamboard insulation between the osb ribs where the panels reside.
The framed panel averages over an inch distance above the curved roof.
I have a unisolar 68 watt stick on on the other side of the roof.
I never recorded the data but there are large noticeable differences according to my IR gun when aimed at the shadowed portion, the portion in unobstructed sunlight, and then directly under the adhered unisolar panel.
The heat under the unisolar can be felt with ones hand, but it is not enough to melt my surfboard's wax which is strapped to the ceiling wax up.
My roof exhaust is fairly capable too.
