Something to consider with solar panels, is that the "ratings" are for an ideal sun-dweller, i.e. summer in Arizona. More typical users further from the equator may see half the ratings, and by the time you get to New England in the winter, you'll be lucky to see 1/8-1/4 of the "daily" output. You can figure eight hours of dim northern winter sunlight might only equal 1-2 hours of full output, so the rule of thumb is probably more like "How many panels can I fit on my boat? How many amps can I afford?" unless you're in a very sunny place.
