Solar charging a deep cycle battery?

I am looking to buy a 15 watt solar panel, a 7 amp charge controller, to charge my 105 amp hour deep cycle battery.

I am going to be running 2 fans that use .52 amps each for 7 hours for 3 days. How much will the solar panel charge the batteries?
Update: ranger: i realize that the battery will run out eventually, i am asking how long using the amounts i listed
