Solar Charging and Amp Hours

No. Solar panels aren't an exact science. Solar input affects panel output. Shade (clouds), sun to panel angles, TOD, charge controller charge algorithms, many things affect the amount of charging output that reaches the battery.

I.e., as your battery reaches full charge, the current drops to zero either via the charge controller or the equalization of the panel and battery, right?

So this simple math is false? 120 watt panel, 12 volt system, 10 amps, 10 hours to charge a 100 Amp Hour battery?
You didn't ask about the differences between lithium and lead acid charging? That's where the opinions really start to diverge. :E
p.s. I know little to nothing about this stuff.
