Attaching solar to roof

Lots of good answers that disregard the OP's real question, "you absolutely could NOT drill holes in your roof". He would be a good prospect for portable solar.

Flexible panels add a bunch of heat to the TT, cup and have short warranties.

not an issue screwing to an EPDM roof or tpm, do like the vents, fridge, antenna etc. are fastened. Use the right angle solar panel mounting brackets, locate the spots for holes, punch through the epdm with a cutting punch to make sure you won't tear it, put a dab of the epdm caulking under the bracket, screw it down, then cover the bracket and screw covers with epdm caulking just like is done on the fridge vent, TV antenna mount, other vents.

I've done this on several trailers with no issues. I suspect this is how it is done on the trailers that come with solar panels.

I'd NEVER try to use adhesive on the epdm, tpm roof membrane to hold any panels down. IMHO it's to easy for the adhesive between the roof membrane and the plywood to come loose with air load and end up making a real mess and problem with the roof.

Buy flexible panels and glue them down.

That's a good solution with just one caveat. They get very hot.

as above; Flexable Panels and glue designed for both materials.

Adhesives are specifically designed for certain materials and are iffy at best for others. A good match is like welding, a bad match is like doing nothing.

Buy long skinny panels that present the least frontal area to the air stream and HD Velcro. Did that for ten thousand miles in the last three years. Renew Velcro every two years.

With a rubber roof glue can't be the only attacment. Screws are necessary. With Dicor, Eternabond and maintainance, what's the problem?

Most rigs have a luggage rail on the roof and you can put angles on the rails and hold at least 3 panels, did that with my first 2 panel's.

"IF" you were going to put Solar panels on your RV's roof and you absolutely could NOT drill holes in your roof (TPO, EPDM etc) how would you attach the panels?

Flex Glue :E

Why can't you drill holes in the TPO/EPDM????????? Doug
