Tilting Solar panels makes a big difference!
I had 2 100 watt Renogy solar panels on my roof and they seem to only have an output of 3.4 amps each. I added a third panel and now the max is around 10 amps this time of the year for the 3 panels. ...

there are some here on the forum who for their particular needs manage just fine with a single G31 battery and 100 watts of solar.
I wrote earlier in some other thread that could manage my particular needs with zero solar, when traveling in a kayak :).
100W solar will harvest ~30AH on a good day. It requires a certain lifestyle, certain appliances (like no DC thermostat in fridge), and a bit of self-discipline, to live on 100W, especially since not all the days are good. If 100W is your ONLY energy source, - it's tough.
I often use under 35AH a day. But my 500W flat array will get me those 35AH 99% of time, including days with low overcast and some rain. And when I need to use laptop more than usual, or charge power tools, or do something inside or outside after dark with plenty of light - 500W will take care of this. Battery bank size is important for solar living too.
