Test it out with an inexpensive portable system and see how you like it...
Buy USED solar panels for up to 90% less than new solar panels. Just need to test them first with a voltmeter and amp-meter to make sure they are good. Then get ~30' of wire, 2 inline fuses, and in inexpensive solar charge controller. Then set it up portable-style the next time you are camping and see how you like it.
Suggestion: 150w for every 100AH of battery in your battery bank.

Questions welcome.
Good luck!
