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...

Ok re-charging rates.. Recommendations vary from both battery manufacturer to manufacturer and from Others as well
Xantrex for exmple recommended 30% C/20 as the peak
Trojan 10%
Lifeline originally 30% as the MINIMUM initial current later reduced to 20%
(That is only for their AGM batteries)
Generally speaking the lower the recharge rate (Down to a point) the longer the overall life of the battery. I suspect that point is Trojan's 10%
I ran around 550 AH of batteries with 80 amps peak for 9 years.
ya, and to get around the worry of to much, you could also use tempature compensated solar charger. I have this set up alredy, just have to add another pannel before I need it yet.
