Taping is a proven method of attaching solar panels to an RV but not those with a rubber roof, OP. My panels and routing of the wire to the controller required 13 holes...no leaks!

Yes, portable panels can be better aimed at the sun...or you can just buy another panel for the roof.

Some folks are using super strong 3M tape and say it works as well as screws


That would depend on the type of roof, tape may hold on a solid fiberglass roof, but if you have a rubber roof membrane, you may find that your solar panels ripped off half your roof membrane when they were blown off after driving on the freeway. Even if the membrane is glued down that glue isn't meant to be structural.

Your roof is already full of holes. Do you think the RV manufacturer makes any effort to have fewer holes?

Drill and Dicor and get the solar working for you.

Hi,

Fixed solar charges when RV is in storage. Portable doesn't.

Dicor is your friend.

One consideration - portable solar panels can 'disappear' sometimes if you're not around..... not to mention the hassle of setting up or putting away everytime you come and go. 3M VHS tape is proven to be a good way to mount solar panels on roof. However, if you're not physically or skillfully up to it then maybe you should either use portable panels or drive over to Springfield Oregon and visit AM Solar.


yes, portables can be a hassle, and can disappear, but also let you park in the shade, and tilt the panels for optimal output. But then roof mounted ones will charge while your driving down the road.

I have three 160W on the roof and three 200W portables. I Dig out the portables if needed, otherwise I rely on the roof.

Putting a couple screws in your roof is no big deal. Think about it all you have to do is waterproof the area of a couple screw heads. Fill the hole with caulk screw in and as others have said a little dicor on top for frosting! Piece of cake!

check out amsolar.com in Eugene they did our install 10 years ago, and friends are going down in a few weeks to have another install there.

even if you do the install yourself, amsolar is a great source of parts for a great solar install.

I had no issues drilling to mount the pannels, especialy when you do it yourself as you know how good you sealed it up. I put a little bit of Geocell to fill the hole and forced some between the substrate and the roof membrane then I put a good bead of it between the roof membrane and the solar mount. then after it was all mounted I did a good hit of dicore over and around the foot. nothing is getting in that hole.

Here's my solution. The panels can tilted up in place or removed and set out in the sun using extension cables:
