OK, I'm going to try to decipher what you asked and then answer.. Continuing on what Brian said, there is air space under the panels but the big one in front is closest to the surface of the trailer...maybe 1 inch clearance. Although the panels will get hot it will probably be cooler inside the trailer since these provide some shade during the summer. However, solar panel performance degrades quickly when they get really hot so I will be watching that this summer.

I guess I just wonder if a plain white roof is cooler than one covered with solar panels absorbing heat/sun?

According to this article the panels reduce inside temps during the summer and add to warming when it is colder. In fact, every article on the subject that I could find (lots of them) comes to the same conclusion regarding reducing the heating of the space below the panels.

The Solar panels capture the incoming solar radiation energy. Some of that energy is re-radiated out the back, and thence onto the white surface of the roof; not a significant factor.
The rest of the heat gain at the roof under the solar panels is thermal energy transfer: just the difference in temperature between outside and inside.
So, the answer is: In sunny weather a plain white roof is NOT cooler than one covered with solar panels.
That being said, a gloss white roof is very efficient at reflecting solar energy; something on the order of 80-90%.

Makes sense to me.

How about ? Ah, right, that's a book not yet made into a movie.

Yes I agree Karen, the roof mentioned in the article is probably asphalt ply which absorb heat vs a white reflective surface on our trailers which reflect heat. I agree, covering something that absorbs heat is beneficial, but something that reflects heat??

About the closest it'll ever be would be an Army Corps of Engineers training film. I saw the beginning of one once, then had a nice nap for the rest.

I bought the two adjustable mounts for the 95 watt panels here: Adjustable Solar Panel Mount Mounting Rack Bracket -- Boat, RV, Roof, Off-Grid and made the one for the 160 watt panel myself. All mounts are bonded to the roof with 3M 5200 fast cure adhesive, no screws.

I would think that the solar panels, with a space between them and the outer shell of a trailer, would shade the trailer keeping is somewhat cooler.
