I have two 90AH batteries that I use for trolling. I switch each day and put the partially discharged one on the solar panels while I fish with the fresh one. I have 200W of portable solar panels but you can make yours work if you are getting enough sun on them. I get 7.5-8 amps/hour in full sun but I'm in the north woods and dealing with sun that is less direct than down south. Still it works very well for me. A normal day of fishing for me leaves me at about 60-70AH so I need only recharge 25-35 and the panels do that easily.
