Trooper solar panel

Mojo

Bostik make a lot more glues than contact adhesive! I wouldn't dream of using that either. If you read my post on my installation, you'd see it was BOSTIK SIMSON, a polyurethane industrial adhesive used all over the boat building industry here on the Norfolk Broads.
I also used the BOSTIK primer to both surfaces before gluing.

There is no way to get this panel off, in the unlikely event of it failing, I'd just glue another one on top!!

Ian - as before, we're not in any real disagreement here. Your approach is different to mine, but neither is wrong. I thought about the idea of just leaving a failed panel in place and sticking another on top, but the problem there (for me) is that the panels change in shape and size all of the time - so in, say, 2 years time there would be practically no chance of getting a replacement exactly the same shape and size.

On the Trooper this might not be such an issue, but it would on the Celex, because the panel is very visible when the roof is up.

So our plans allow for the panels to be removed. On the Celex, where it's stuck down direct to the roof with Sikaflex, that won't be at all easy, so I really hope it never comes to that! Fortunately it seems that most failures occur very soon after fitting (the first part of the "bucket curve", and it seems none of us have got to the other end of that curve yet, as they are supposed to last 20 years+).
