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...

All replys are greatly appreciated.
Do 1.5 watts of solar per AH of battery and you should be fine.
(300 watts of solar for 215 AH of battery)
I currently have 210 AH of battery, and 420 watts of solar, and I plan on adding another 200 watts of solar this fall.
My DW said she wants to live like normal when we are boondocking, that means we run the inverter to watch tv etc. Our use averages about 50 AH per night, and we get fully charged daily, as long as there is sun. Not as good if it's cloudy.
I have a 225 AH battery bank and use 40 AH per day. My GC2's are back up to 100% SOC by early afternoon each day with 200 watts of solar.
