Working backwards, fully charging lead-chemistries by 1:1 solar means requires about 8.45hrs of Full Sun Equivalent on MPPT, and about 9.7hrs FSE with PWM. **There is nowhere in the United States that averages 8.45hrs of FSE year around**. | Working backwards, fully charging lead-chemistries by 1:1 solar means requires about 8.45hrs of Full Sun Equivalent on MPPT, and about 9.7hrs FSE with PWM. **There is nowhere in the United States that averages 8.45hrs of FSE year around**. | ||
+ | Workarounds: | ||
+ | * Fully-charging becomes possible with attentive panel tilt, requiring only 5.5hrs on MPPT and 6.4hrs on PWM. | ||
+ | * fully-charging becomes possible with shallower cycling, like 75%. This is the equivalent of the 2:1 systems below. | ||
