If you're shy about drilling holes for the mounting brackets, use VHB tape.

Interesting idea...so you are suggesting using VHB tape to fix the mounting brackets of the solar panel to the roof. I did not think about that, definitely worth exploring...anyone else on the forum try that?

I'd steer clear of flexible panels. There is some risk in quality and electrical harvest is going to be less because of thermal characteristics.

I have not come across any research suggesting quality issues with flexible panels, but I did come across a comment from a user that with no space between the roof and that back of the panel, the heat buildup can reduce efficiency. is that what you mean?

thanks for the advice though, will keep in mind.

There have been a few installs just using the VHB tape. If I had an EPDM roof, I'd do like most do and fasten with screws and Dicor. My worry would be about the EPDM lifting or shifting.

There were some reports of the flexible panels not being all that flexible and some cracking was experienced. Yes, a panel conventionally mounted using brackets will outperform the flexible panel because of thermal differences from the different mounting methods.
