    Dave Newell's offer for funsters at Newark Show looks very good value... see his thread.

    I notice that it's Polycrystalline. Monocrystalline are generally held to be more efficient, though more costly as a consequence.

    No Chris your not, unless like Vienesse you can't.

    I have fitted my own and then moved it from van to van with it now being on it's 3rd van. If your are reasonably competent at DIY, dont mind getting on a roof and drilling a hole in your roof then it's not rocket science. Can be a bit fiddly from time to time but nothing more.

    Unfortunately I can not see the link to your potential purchase as Im at work and ebay is banned :Sad: so can't comment on it's quality.

    pound per pound you would be better getting an 80 watt panel as they tend to work out cheaper per watt than most other panels and are only marginally less output than 100 watt panels in real life situations

    Personally, I'm going to go semi-flexible. Much easier to fit (just glue it down), and lighter. A bit more money, but no horrendously so. 100W for about £170.

    I'm not sure what your'e getting at Roger? they're both glass and both heavy. Polycristaline panels just require more surface area watt for watt. I've got one of those poly's here that I bought for £60 delivered purely to evaluate it and had it in the Sun today giving just over 4 amps with a modest load applied to the battery.
    If anyone local wants one (panel only) they can collect it here for what I paid.

    Not so anymore Andy there are plenty of 100 watt units at similar prices now and without being any physically bigger.

    Mine is a 250w house type one, but it does require a fair bit of roof space. Cost just under £200 from ebay delivered, and ebay again for the controller, 30 amp for under £30. Having being in the body shop business most of my life, I know there is nothing sticks better than sikoflex. The motorhome had one fitted before us, and fastened the same way, and had been removed with a hot knife or a cheese wire. Obviously they had paid a lot more money for it, as I wouldnt bother to remove it if I was selling the RV. As usual, if you want to see how to fit one, go to youtube.

    only thing missing from that kit is mounting brackets so price in another 10/20 pounds dont worry about the panels being mono or poly theres not a lot of diffence in size and weight is neglible and 100 watts is one hundred watts

    I just preferred the corner mounts, those side ones you indicate are only 180mm long.
    Used stainless steel screws and washers and screwed through the corner mounts into the aluminium frame.
    Used Sikaflex 512 to hold to roof. I had marked out the area where the mounts would sit and used very fine wet and dry to ensure a clean area on the roof. A liberal layer was appied to each mount prior to fixing having attached the cables first ! ! Entry box is also Biard and is sealed/adhered with Sikaflex 512.
    Care was taken to ensure roof was drilled so that cables arrived in the MH inside the cupboards and was able to drop through the back of floor cupboards.
    The cross member on the roof is dead fit to hold panel down (as if it needs it) and back cross member not shown in photo does the same.

    Larby,

    Thanks for the reply, it was very useful.
    The side mounts I mentioned are designed to be used in addition to the corner mounts not instead of. I wanted your opinion on whether such intermediate supports are necessary?

    The other question I need to resolve is the use of Sikaflex 512 verses Sikaflex 252.

    Gordon
