BougeRV Flexible Solar Panel Waterproof Butyl Rubber Tape, for Yuma CIGS Thin-Film Arch Flexible Solar Panel, 3.98''Width x 16.4 Feet Length

This stuff is high quality. I used it to install flexible solar panels on my boat. Unfortunately the panels were defective and let me tell you how hard it was to remove them. This tape gets 6 stars. Those panels weren’t going anywhere. Just a shame that the panels weren’t as good as the tape.

This stuff is *sticky*. I don't expect the solar panels I mounted to the slightly curved roof of my trailer to go anywhere, ever.

Very sticky. Excellent butyl tape.Sticks to house paint surface.

I'd give it a 5 but need to see it working in a year first. Otherwise, this worked like a charm and some 5000 miles later the solar panel is still firmly attached to the roof of my camper!

Solid butyl tape that holds strong and withstands weather. I have it installed under two rooftop solar panels and they have held strong after a year of hard weather and lots of miles. Size fits well for all sorts of uses and is also good for sound deadening material.

This is definitly going to stay in place, installed it on back side of flexible solar panels, make sure it is lined up where you want it because it is almost impossible to remove once it is in place.

Poor adhesion and comes loose in hot weather

Wider than used on the CIGS panels. HARD to cut length-wise, pretty gooey but that’s how it works.
