Have just re-read the article again. Or - tried to. Maybe somebody with better detective skills will decipher it better than me :)
160 AH bank in an excellent shape needs 0.02-0.08A in Float (not measured in these experiments, but he says it does, so let it be). Take a middle, 0.05A*24H/5.5 hours of sun = 0.22A panel. This is for 160 AH.
For 2 GC, 225 AH total, it would be 0.31A panel or 5.6W. This is - in excellent shape. If less than excellent? 8W,10W - who knows...
Another pointer from the article: keep controller-less current under 0.3% C. For 2 GC, 225 AH, this is 0.68A or 12W panel. A bit different from previous 5.6W, isn't it? Did he mean 3% for panel in good or bad shape? Who knows...
The gist of the story - the only that I could deduct from all this - know your batteries. If it needs 1A panel to float them, then it needs 1A.
