-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).+[[https://mouse.mousetrap.net/blog/2020/07/02/the-problems-with-11-solar-charging/|Working backwards]], fully charging lead-chemistries from 50% [[electrical:depth_of_discharge|DoD]] by 1:1 solar means requires about 8.45hrs of Full Sun Equivalent on MPPT [[electrical:solar:charge_controller|controllers]], 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.
