    All depends on the power rating (link to the ones you've been looking at would be useful) and whether or not you can keep it oriented towards the sun (especially in winter).

    I tried one of These a few years ago when I knew nowt and was daft (as opposed to knowing summat and still daft :Smile:) and found it to be useless.

    I'd say go for it. You can always point it towards the sun, which is a bit trickier with the roof mounted jobbies, and cheaper, and you don't have to drill holes in the bodywork.

    I got the leads hard wired onto the leisure battery rather than the alligator clips supplied.

    Max power is less than 1Amp ... to be exact 743mA

    that is in FULL sunlight.. at best, it will keep a fully charged battery topped up, providing it's not being used.

    I was just clarifying.. sorry I mentioned it.

    In my opinion 1 amp at max, and I stress MAX charge of 1 amp and that's only available for an hour or two on a sunny day (unless you stay with it and move the panel every hour) is not even going to to keep up with self discharge of all but a brand new battery.

    just one point to remember with that panel.....

    Please note: This kit is not waterproof. The panel is water resistant so suitable for use in light showers but the charge controller unit should always be kept away from moisture as it is not water resistant.

    which will mean taking it indoors every time it rains or it could get waterlogged and fail.
    it seems Amorphous panels are not waterproof.

    I nearly bought a 60w panel from maplin's a few years ago...had to ring and cancel the order once I realised.

    For the same money as the maplin folding unit, you could buy a 40 watt panel c/w a digital charge controller from flebay.

    Are you saying the panel's themselves are not waterproof or the whole unit because of the controller? The charge controller is a separate box that clips via short leads to the battery and is meant to be fixed inside the vehicle. There's a a single cable (something like 1.5 - 2m) that connects to it from the panel. So in my case when it's rained the panel has been the only thing outside.

    To reinforce what others have said...don't expect much from the 13W Maplins panel and you won't be disappointed. It definitely won't keep up with the drain from my compressor fridge but in decent sunlight it does stretch things out. And on a very sunny and hot day in June last year (yes, we did have one), when I flattened my battery it keep the fridge ticking over enough to keep things cool enough inside.
