    Please can someone give me some advise on fitting another solar panel to the one I already have fitted(100w) I am looking at paying around £250 for the panel and a good twin controller.

    What sort of advice are you after? Have a search on the forum as there are lots of threads about fitting them etc. @Techno has done some good ones.

    It depends on what sort of controller you go for. The basic ones are only £40 to £50 but I probably should have invested in a good controller which costs about £200 but will look after your batteries once programmed a lot better.

    I would say you can get a good 200W controller for around £70 or £80 perhaps a little less. I like the Victron ones but Techno has his own favourite. You shouldn't need to pay £200 unless you are after something for a very high wattage.

    not sure about that. A good controller will let you programme in exactly how your battery should be charged. I don't have any first hand experience of using one so I can't say more but I would be interested in seeing what controller you have in mind for £70-80.... If it fitted the bill I would probably get one. Can you post a link?

    This is the one I have and Victron are the only make of controller fitted by VanBitz after trying a number of makes. It is a very clever controller which will keep batteries in the best condition. They are a Dutch company though no doubt the units are made in the Far East but they answer emails promptly if you have any questions - and in English!

    This one is up to 200W in a 12v system. Have a search on the forum for more info. https://www.victronenergy.com/solar-charge-controllers/mppt7510

    I agree with you that it's a decent controller but it wouldn't have the capacity for my set up. I wouldn't use it with more than 1 100w panel. For the op with 2 100w panels I would get the larger capacity which is about £180 but that said if the op can't afford the larger one I agree it's better than spending £40 on a cheap and cheerful one.

    In total with all my panels plugged in, on a sunny day I'm getting 500w :)
