Default 24 volt solar panel for 12 volt battery bank

Though this has probably been addressed a hundred times on this site and elsewhere a hundred times more, I can't at the moment find what I consider a final answer as to what happens when a 24 volt solar panel meets up with a 12 volt battery bank. So far I've heard it would fry the battery like the old battery "boiler" chargers, that if a controller is put between the battery and the panel you'll get charging of 12 volts but for only half the panel's rated watts, or that an mppt charger will make everything right. Does anybody really know?
