I bought two Unisolar 68-watt flexible solar panels with the idea of installing them at the edges of the fiberglass roof on my coach. They are installed by removing a plastic film and then laying the "sticky" side down.
Information I have is that this self-stick was primarily designed for metal roofs (although there are words implying "any roof").
Has anyone had any experience with installing these panels on an RV using the self-stick feature? The edge of my RV is slightly rounded which will be ideal if they hold. I'd like to see if anyone has had any success with this before I contact Unisolar for their advice.
BTW: these flexible panels are amazing... nowhere near as temperamental when it comes to shadows and output.

You may have trouble contacting UNISOLAR, since their parent company filed for bankruptcy. Good luck though. I've seen successful threads on here or another forum of UNISOLAR installs.

Here is a bunch of installs. I am sure someone did Unisolar self stick panels.

I found this link to be pretty interesting:
http://www.rv.net/forum/index.cfm/fuseaction/thread/tid/25994823/gotomsg/25995153.cfm#25995153
Many conflicting opinions; one saying that a certain configuration is ok and another saying that it's not. The OP seems confused.
Still... weeding through 48 pages there are glimmers of good information here. All about wiring configurations and not much about whether or not the sticky Unisolar panels stick to a fiberglass roof or not; however, there are photos in other threads of them apparently sticking just fine. So I reckon I'll be brave and test it.
Thanks for the URLs.

I know of one couple who have a fiberglass Scamp trailer, and they attached a different brand of flexible panel to the top with VHB (Very High Bond) tape. Their solar panel didn't come with stickum to start with. They've driven something like 8 months and many thousands of miles (full timing) and it hasn't come off. Sorry that isn't directly to the point, but it does show in general that adhesives can stay stuck to fiberglass.

I actually bought the Unisolar panels without realizing that they had their own "stickum" so I have a roll of VHB tape. But I am pretty sure that the VHB tape won't like cooperating with the Unisolar stickum so it's either that or try to remove it somehow.
I just recommended Unisolar panels - which are priced nicely right now - to a friend with a Scamp.

I have 4 68W panels on my roof. Installed a few months ago. Can't tell you long term, but so far so good.
BTW -- a company seems to take the 68W unisolar panels and sells them with a little extra edging, etc.

There are companies that install the self sticking panels (unisolar?) for you. The panels stick to fiberglass and they don't come off. Of course you need to be sure the roof has been cleaned very well before sticking them down. Eternabond stays on fiberglass (and TPS too I understand) so does the VBS tape so it is not too surprising that the solar panels also work fine.

I put a 128 watt uni-solar on my rubber TT roof 2 weeks ago, the back is really sticky. Should be good for fiberglass roof. Just make sure you put it where you want. No redo's with these panels.
I don't believe you will get the panel off once it's stuck.

Thanks everyone... makes me feel better knowing others have done this before me. I'm starting to wish that I had bought a couple more of these 68-watt panels after checking out the resistance to shadowing.
