Ok, sure, longitude, weather, the angle of the panel (which if on some vehicle roof is horozontal)....length of day, there is no one setup...
But that said, is there a basic rule of thumb regarding how big a solar panel in watts a person needs to, with an MPPT controller, trickle charge an AGM starter batter of size "x" amp/hours.
I'm not looking to charge my starter battery so much as I seek to keep it "topped off," as a shore plugged in trickle charger would do.
Thank you.
