Am considering getting a portable solar panel for my small caravan which has a tiny battery bay, with only space for one small leisure battery (currently 85Ah). I expect to be up to 4 days off grid at times.
I won't be using an inverter at all but may get a small 12volt TV. I have done some calculations (based on this helpful page) and I reckon I need an 80W solar panel to keep me topped up.
So I see this portable one on Amazon which seems to have decent reviews.
I also see plenty of similar ones a lot cheaper on eBay...
Are these portable ones any use?
Or am I better off going with the permanent installation?
