    Hi,

    Any more users happy/unhappy with semi flexible solar panels, Biard or others?

    I have a space on the MH roof that only a flat panel would fit. It would also cover the old screw holes where I removed the Aerial for the Satellite dish.

    There is also the weight advantage but the obvious heat issues.

    Any suggestions welcome please?

    We would have liked to put the thin light weight flexi Solars on. But the Roof is corrugated . So have to put the regular solid ones on.

    I have fitted three 200 W Biard standard kits to mine and 2 friends M /H
    There standard kits seem to be good quality.

    i have just ordered 2 x 100watt panels but im perplexed as to how to fix them to the roof, ie silkaflex them straight on or space them off slightly to allow air flo under them. if spacig them what have others used?
    i wish i could type as well as spell

    i would stay away from flexible panels fixed directly to the roof as you dont get an air gap to cool the panels , more heat=less efficiency. just my take!

    You roof is unlikely to be flat enough anyway. Buy brackets or some aluminium angle and space them.

    if i give them an air gap are they likely to oscillate (must look up the meaning of that word it sounds good) with air flowing under them?

    Thanks for the replies.

    Managed to find space for a smaller rigid 40w that I have in the Shed!

    Speak to Chris at Southern Solar Alliance, he had some flexibles on his stand at Peterborough

    I think heat issue is overblown, if its hot and sunny then you don't need so much power from them anyway, I think weight and aero counteract that(y)

    And I have stuck mine flat to the roof with sikaflex(y)

    i have had a 80 watt semi flexible sikaflexed to the roof for the last 3 years with absolutely no issues in terms of performance on negative impact on the roof. i did not want bracket type panel. the only point i would raise is that they are coated in a plastic on the solar surface and this attracts dirt so needs a wipe regularly.

    Sorry I've taken so long to see this, Re roof I use this to get it really clean then just a wash now and again with a good car wash keeps it clean, but use only as per instructions and wax after as it will remove all the crap and any wax ok.
    Re wiring, I wanted everything to be as neat as poss so I found that siting the panels where I wanted them on the roof, if I drilled directly down the hole came just inside the cabinet doors, which in the Hymer is ideal cos they have a trim along the inside thats takes a stick on cable trunking so that it is very neat and invisible to the eye(y)
    I will try and get some interior pics if I remember;)

    We've had a Biard 100w semi flexible panel on for about eighteen months but it suddenly became very inefficient and has now stopped working. It looks ok but has gone open circuit and it appears to be a fairly common problem with these units. Going to replace it with a better quality one made by SunPower. Might be due to heat or flexing.

    i have an 80 watt sun power semi flexible panel in its 3rd year now, main thing i have noticed lately while giving the roof a good polish was that the " plastic coating has lost its shine, cant say i have noticed any loss of performance as yet.

    I saw some recently where the plastic coating had gone quite opaque, not sure about performance.
