3M 4941 VHB Double-Sided Acrylic Foam Tape
I first tried to mount my flexible solar panels with rivnuts and screws, but the panels didn’t lay flat. Laying flat was one reason I wanted the flexible panels! So I found out that a lot of folks use this Very High Bond (VHB) tape to mount the rigid panels. I decided to give it a try. Mounting without holes is a plus! The only downside is removing them will be a job. To install them I cleaned the roof, then wiped it with alcohol and laid the panels. I used a laminate roller to get good adhesion. After hundreds of miles, they are still holding strong!
