    I an finally going to get around to having a solar panel fitted on the M/H prior to our tour to Scotland later on, I see that there are several on Fleabay, any recommended panels or sellers, and just as importantly, anyone had bad experiences with sellers or panels. I suppose something like a 100W Bosch might be OK, what do I need to look for in a controller please.

    Sunstore - excellent kit. MPPT controller - no contest.

    You won't go wrong with a monocrystaline Bosch. For the controller, if you can get an MPPT as these are far superior in efficiency than a simple limiter.

    You can get dual output controllers, but if you have nothing heavy drawing on the starter battery, you won't get much benefit from the extra output.

    Keep the cable between the controller and the battery as short as possible and a reasonable gauge. No need to go over the top as 100w will at most give 9 amps of charge.

    Mount the panels to give an inch or so of free air underneath them as their efficiency drops the hotter they get.

    (is there some irony in fitting solar before visiting Scotland :))

    in your dreams maybe. :Laughing:

    In theory it will produce 8.33amps....in reality it will produce 7amps in good overhead sun.

    6 amps is about optimum
    I have witnessed 18 amps from my 300 with mppt and that is more than the panels projected/claimed output

    It depends how much roof space you've got. If you've got plenty, just get cheap panels and controllers. You get more output from just buying more capacity than buying better quality. However, if you've only got room for a single panel, get a decent panel and decent MPPT controller to maximize output.

    Personally, I prefer semi-flexible, as they are so much easier and thus cheaper to fit and don't look so ugly, unaerodynamic and nickable as they don't stick out from the roof.

    there are various amounts of offers

    many members have many types depending what you require and budget.
    i bought the wrong solar chargers twice, first was a 10 amp cheap second was a 20 amp cheap now i have a 30 amp ..
    and two 150w panels. thats my choice it wasnt that much more in money,

    here is a budget system from the guys i bought from first class service.
    the reason i selected this as an example is that you get the plastic fixing brackets for the ends and side very important also dont drill onto roof you will need a flexible bonding agent as shown
    http://www.ebay.co.uk/itm/Biard-100...143299?pt=UK_Gadgets&var=&hash=item58a548f243

    you need this for fixing to roof incl round the cable entry box.
    http://www.ebay.co.uk/itm/Sika-Sika...nding-Solar-Panel-Bathroom/200974928813?rt=nc

    batteries if required,
    single battery, http://www.ebay.co.uk/itm/12V-110AH...ervan_Caravan_Accessories&hash=item27cfc7649a

    pair of batteries .
    http://www.ebay.co.uk/itm/DEAL-PAIR...ervan_Caravan_Accessories&hash=item1c1c5bef69

    you will need battery clamps and heavy duty battery cable from a good car component shop ,, i got mine from maplins not a bad price, make sure battery dimensions can fit under your van or in one of the outside compartments not with the gas and not inside anywhere as they can expel gasses ,,, also secure with the correct means and battery trays with sides or similar. i running cable under van is the only option then cable seal and cable tie often to stop cable wear this can cause arking and be dangerous ,,,
    a good dry day is a must to cure the sika flex fixing compound,



    i have this set up which i just completed a few days back works well and
    i also just fitted a inverter as shown not always required ,,,

    2x http://www.ebay.co.uk/itm/281248073912?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

    totaly agree check dimentions of any panel

    totally agree check dimensions of any panel your interested in buying
    as you may have several roof windows or a rach or box even a satellite or aerial all get in the way..
    like the idea of the flexible panels never seen them but have noticed them on ebay,

    But I said at most and am not concerned with fractions of amperes.
