    Has anyone got any experience or advice on flexible solar panels as the motorhome has limited roofspace?

    Fitted the first one and very happy, decided after 10 months to fit a second and then about 2 months later the first one died so decided to try a 150W from Renytek (they don't sell it anymore) which has a white backing instead of the Biard aluminium backing. Then the second Biard died after 14 months so after that failure I decided to get a normal panel and put that over the dead panel. I now have 290W, 140W rigid and 150W semi, the rigid gives a lot more output than the semi even though it has 10W less.

    Our Biard lasted about 15 months so replaced it with a Lensun, time will tell.

    Presumably you mean you have limited FLAT roof space?

    it sounds like flexi solar panels are a waste of time and maybe the road pro was right in that the cheap ones are rubbish.
    So I am none the wiser really, ah well might be new developments in the future.

    I use a flexible panel which is not fixed. Lots of advantages to outweigh the obvious disadvantage. Positioning, cleaning, replacing. It stores under the sofa cushion. Might be a good option if space is limited.

    as a non fixed panel how do you get the power to the batteries, daft question I know but I am clueless on these matters.

    I have the cable from the solar controller coiled with a Velcro tab under the passenger seat. I feed it out through the side window and the connectors just clip together. I stand in the doorway and slip the panel on the roof, prop it up against one of the front tyres or place it on the windscreen depending on where the sun is. All very easy and by not having it out 100% of the time it needs a lot less cleaning (and is much easier).

    Look at the millions you see in solar farms, I've never seen stick on.

    I'm considering flexi-panels because they are much lighter and low profile (3mm) - so that I can feasibly put them on the overcab roof, either side of the roof light vent, rather than taking up space on the main part of the roof further back. Has anyone tried this?

    Our Lensun panel is still going strong and seems to deliver more current in poor sunlight conditions than the previous panels did which is good for the UK.

    Is it a 100W panel?

    Very interested in the Friendly Green Giant flexible panels - they claim to use the latest back contact method and "flatter" connecting boxes - but the price @ £0.87/W for monocrystalline panels is fab! Are you using the fixing kit they sell, or have you stuck the panels direct to the roof? If you're using the kit, how are you finding it - do you get any wind/flex underneath the panel, as it looks like they're slightly raised up by the fixing kit?

    No the fixing kit looked a little bulky to me and even if it wasn't the panels are fitted at the front of my roof and like you I thought that the panel would get air under it as I travelled along and it might flap about and damage it, obviously I had some previous experience fitting and removing the Baird panels so quite happy to stick straight onto the roof(y)
