The BATTERY SCIENCE rules for charging a depleted 12VDC battery in a short three hours time is to hit it with 14.4VDC for two hours and then 13.6VDC for an additional hour.
That last hour at 13.6V is where solar comes handy. Pretty much any panel will generate enough amps to keep it at 13.6V.
This scientist would leave it at 14.4 (14.8 actually) till the battery is charged never mind the time, then and only then drop to 13.x (where x depends on temperature) float.
I suspect Roy has been reading too many PD converter blurbs. :)
