Just wondering what people do when parked up at a site or aire, etc., when there is no EHU and it is snowing & settling on your solar panel. Unless you happen to have a ladder & a long brush on board & can clear it, what do you do for battery charging? I know not much charging will happen at this time of year anyway, even without the snow, but intrigued as to how people cope. :unsure: Can you tell I'm stuck indoors with not much else to do? :D:D:D

Edit. Ooops! A list has just arrived courtesy of SWMBO :D2:D2

I bought one of those extending handle squeegee things in a French supermarket so I can clean the skylight from ground level if I want. Handy for clearing the solar panel from the skylight too, although the panel will probably ice up as well. There are ways and means.

Our batteries haven't been doing too badly with a 100W panel in the last few weeks despite the weather - it was Dec and Jan when they were struggling.

Errr Switch the engine on

To be honest IF the roof light opened the other way would be able to sweep the panel with the 3m long wash brush we carry around to keep Maxine clean although if I was mad enough I could send Steph up the ladder at the back to do it

Just wait for the sun to come out and melt it. When not enough to melt it, there's probably not enough to charge a battery either.
Or take a drive and let the wind blow it off.

I can reach to clear 3 of the 4 solar panels through the rooflight standing on a seat. Not only snow but fallen leaves at other times, even partial shading of a panel can make a big difference to the output.

I'm puzzled.
If shading makes a "big difference", why bother only clearing 3 out of 4 panels?

Because when wired in parallel (as most panels on motorhomes are), each panel is 'standalone' as far as shading goes. So the three that are cleared all act as normal & only the output from one is still affected by shading.

Even if wired in series, they would almost certainly be wired in two sets of two, with each series connected pair connected to the other pair in parallel, so one pair would still work ok.

If you have to put some charge into the batteries then just run the engine for an hour or so. Worth doing this at some point regardless so that you have an idea of how much charge your alternator can put in to the batteries just in case.

Mistake 1 - no ladder and brush

Mistake 2 - no battery-to-battery charger to arrive on site with them full, or to recharge with quick engine run

Mistake 3 - parking in snow with solar.

Mistake 4 - Letting SWMBO see you typing 'not much else to do' :LOL::LOL::LOL:
