General rule of thumb is you want 6-7x the solar as your AH as well in sunny areas, up to 10-12 in more northern areas with less reliable sun if you are making a system you want to use full time. Soo ~650 watts solar for a 100 AH battery you are draining to 50%. A lot of factors work into this number, but following that rule most people will be okay.
Lifepo batteries are the ideal solar system battery by a long ways if you're gonna use your system a lot, but you're probably better going more and cheap setting up quick if you don't plan on constant use.
