If you team them with a MPPT charge controller you can charge 12 or 24v batteries. The panel's Voc is a bit high, so if you want to put 2 in series your charge controller should be rated over 100V on its input, usually that means a 120v model. If that doesn't mean anything to you at the the moment, that's OK. Just ask for more advice before you buy a charge controller.
Are you familiar with what you need to check for when buying 2nd hand panels?
