    Hi

    I have a smal folding Gobur caravan which we occasionally use for guests, its easy to tow and it takes up no room.:)

    When folded down, the roof is below eye level so i would like it to be neat

    It has a 75 ah battery and a slight curved roof
    It has led lights and a lcd telly

    I would like to fit a solar panel on the roof and have found this one

    http://www.ebay.co.uk/itm/100W-Semi...663993?hash=item4635d1f939:g:~RUAAOSw3ydVu56m

    Question, has anyone fitted a flexible panel and if so how did it perform, secondly how did you attach it

    I know the lack of air gap is a small issue but I have over specified the panel to make up for the loss, i think

    ta

    Several posts on this forum about them failing in under 2 years, we also know someone who had one fail at 18 months old.

    A friend of mine has a chandlery shop and he sold quite a few of these to boat owners. The general consensus was that they underperformed by quite a large margin. Don't underestimate the air gap below a solar panel, it is very important

    Hardly surprising the way boat owners fit them.:D

    Saw this in France last year.

    The air gap is only for cooling, if the roof conducts the heat away you are on a winner.

    Anyway, what have you got to loose, £100, give it a go.

    We picked a new cheap 60w one at a show last year and I fitted it to our new PVC using some Sikaflex - the most taxing part was drilling the hole through the metal roof in the correct place for the cable ... thankfully after a lot of measuring and checking, checking and checking another few times, I got it right first time ... phew!

    If we hadn't got it already (we bought it before we knew we were changing PVCs!) I might have just gone for a standard rigid one but I must say that it was very easy to fit the panel itself as I just did 'squiggles' on the raised roof ridges and around the edge of the panel and pressed it on ... the hardest part was cleaning off all the ruddy Sikaflex that had got everywhere (don't ask!) which took much longer than the actual panel fitting!!! :D

    The panel on our previous PVC was an Alden 75w one which worked great (we wild camp or use aires all the time) so I was a bit concerned in case the smaller panel wasn't adequate, but it performed faultlessly when we had 6 weeks away so we're very pleased with it. If needs be I'll just add another one in the future but doubt if I'll find the need.

    for anything like sike and silicon you need to use big wipes from any builders merchants or poofix places or use baby wipes to clean up

    Mines sat in the garage awaiting fitting
    Going to use Sikaflex and a terminal box , bonded to the roof

    I bought a 100w for £96 delivered , the white one that comes up on eBay

    I already have a 'steca' controller from my motor home when I fitted a mppt upgrade

    Just been on eBay and you can get a mppt for around £25 ,anybody used one ?
