How much time a 10w Solar Panel need to charge 200 Ah battery
I'll make a few rather generous assumptions since you haven't provided details.
Assuming a 12 volt battery that has a charging efficiency of 65%, a panel that is optimally positioned so that it will produce full rated output for 12 hours a day, perfect weather, a charge controller that maximizes the power tranfer to the battery, no losses in the wiring, and no load on the battery during the charging period, it will take a little over a month to charge your battery.
You will have collected about 2 1/2 KWH of energy worth perhaps 25 cents to a dollar depending on rates in your area.
