Can I make an effective solar pannel, that can charge a twelve volt battery, with three six by six solar cells that are 3.73 wats each and .52 volts each? Or do i have to exceed 12 volts in order to charge the battery?

You do have to exceed the voltage you are trying to charge.  You need about 13.5 or 14 volts to reliabily charge 12 volts.
