% insolation 130x5.5q5 miliwatt hours maximum power output
Insolation 10 year average for Atlanta 4.3 hours
Daily average charge capacity for this system at 100% efficiency 715 mWh x 4.3 = 3074 mWh ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4040/3074=1.3 days to charge its dead battery with this charger operating at 100% here in Atlanta on the average.
