    My brother has moved home and due to lack of parking space on his property he has had to put his motorhome into storage when not in use. He does not have a rooftop solar panel installed and the storage do not provide an electric hook up for keeping batteries topped up etc. Does anyone know of any solar powered gadget they can leave in the cab window that will successfully trickle charge his cab battery to prevent it from draining completely flat?
    I've see some solar powered units for sale quite reasonably that you can leave in the car window to charge but whether they are powerful enough to do the job I haven't got a clue? So any advice would be most appreciated.
    Thank you

    Most of the ones you see for sale for keeping batteries topped up are a waste of time often only 2.5 watts, need absolute min of 10 watt even that won't do much behind a windscreen as output will be reduced as windscreens make excellent UV filters. Best to get a 20 watt panel and cheap regulator. Probably better to spend a few more quid and fit a roof panel would then be able to keep leisure & cab batteries charged and can forget about it.

    I got one of those windscreen solar panels found it to be a waste of time. I did have the solar panel on the roof but it didn't change the cab battery I have now fix this by fitting a battery master which works with the roof panel and is working great :) The long term benefits would be getting the roof panel fitted.

    Another vote for a roof panel and battery master. dont know what van your brother has, but ours did not charge the vehicle battery from hook up, only the leisure one. Believe this is not uncommon in European vans. Battery master fitted now all ok, both batteries charge from solar and hook up now. result.

    On our previous motorhome - an ancient Pilote on a Talbot base, we used to suffer from dead battery when he was on the farm (local storage!). We added a small portable panel, directly connected to the vehicle battery, and left on the scuttle behind the windscreen, and never had the 'flat battery' problem again! It's only a trickle charge, but that's all you need to keep a vehicle battery happy.

    We don't use it now, as we have two roof panels, and a Battery Master.

    I did use a 10w panel to maintain the battery of a smart car in a barn whilst in storage quite successfully. So for the minimum cost 15quid from Aldi currently it is worth a punt

    I use one currently to keep the classic battery up whilst the car is under "restoration". So far it is keeping it at a consistent 12.8volts.
