 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**. ​ The highest is Honolulu with an average of 5.96hrs. The highest monthly average is Las Vegas in June (7.69hrs). 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**. ​ The highest is Honolulu with an average of 5.96hrs.

-Fully-charging becomes possible with attentive panel tilt, requiring only 5.5hrs on MPPT and 6.4hrs on PWM.+Workarounds:​ 
 + 
 +  * fully-charging ​lead becomes possible with attentive panel tilt, requiring only 5.5hrs on MPPT and 6.4hrs on PWM
 +  * fully-charging lead becomes possible with shallower cycling, like 75%.  This is the equivalent of the 2:1 systems below
