-The actual hours of FSE will depend on where we are and month of the year.  If we want the solar to Just Work((by itself, no help from [[electrical:12v:alt_and_solar|other charging sources]])) we have to size it for the worst average yield we will experience.   Let's consider these very different scenarios:+The actual hours of FSE will depend on where we are and month of the year.  If we want the solar to Just Work((by itself, no help from [[electrical:12v:alt_and_solar|other charging sources]])) **we have to size it for the worst average yield we will experience**.   Let's consider these very different scenarios:

-We can work backward from FSE and required Wh to get our required panel:  Wh required / hours of FSE / system efficiency((I will stipulate .85 for MPPT and .70 for PWM)) = panel wattage.  Assuming an MPPT-equipped system:+We can work backward from FSE and required Wh to get our required panel:  Wh required / hours of FSE / system efficiency((I will stipulate .85 for MPPT and .70 for PWM)) = panel wattage required.  Assuming an MPPT-equipped system:
