Just a little heads up on anyone worrying about just using Sikaflex to stick their solar panels on the motorhome roof, I've just had a wonderful afternoon trying to remove four 4in alloy brackets off the roof of my Hymer, I managed to get two off but had to give up on the other two and just cut the sticky up bit off flush.
The two I managed to get off had a small gap underneath so I was able to push a very thin blade under bit by bit enough to loosen them after about ten minutes, but the others had no gap and no amount of cutting, pulling or pushing was going to loosen them, I did try thin wire but to no avail.
I have no idea what adhesive was used but it was white and rubbery so assume it was a Sikaflex type, now these brackets were screwed as well but even without them the panel would never have come off EVER.
Now I note the recommended way to stick brackets is to have a couple of mm of adhesive between bracket and roof, now I suspect the reason for that has something to do with adhesion, but it is a bloody good idea if only cos if you ever want to get them off it will be virtualy impossible without the gap
