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**. | ||
- | + | Fully-charging becomes possible with attentive panel tilt, requiring only 5.5hrs on MPPT and 6.4hrs on PWM. | |
