-Working backwards, successfully fully charging lead-chemisties 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).

 This slightly [[electrical:solar:overpaneling|overpaneled]] configuration brings in extra power for heavier loads or for use in areas without much sun.
-Working backwards, successfully fully charging lead-chemisties by solar means only requires about 4.25hrs of Full Sun Equivalent on MPPT, and about 4.85hrs FSE with PWM.

 On average, this would work in Little Rock, San Francisco, Phoenix, Birmingham, Atlanta, New Orleans, Albuquerque, Tulsa, Las Vegas, San Antonio, Houston, Salt Lake City, and Casper Wyoming.  Winters will require power management.
