Watts needed
I have read where folks suggest any where from 1 to 2 watts of solar per ah of battery. My question, is this based on battery rating (ie 215 AH) or is it based on useable amp hours(105)? All reply...

for a 6V GC battery the recomended charge amprage is 10% of your total amp hour capacity at the 20h rate of your entire battery bank.
With flooded you can go below 0.1C, it will just take longer to get to Absorption. AGM recommend 0.2C optimum current, and again, you can go way below 0.2C.
The OP never told what battery he has. Or how he is going to use his solar - daily energy needs, days of camping etc - IMO, this is what solar planning should start with.
