Can you charge a 12v battery with 24v solar panel?

I bought a 12 volt Sun Xtender battery (model is PVX-340T) in preparation for the solar installation I plan to have installed in 2017. I've been looking into which solar panels I may want to use for my rooftop install (thinking Q cells currently) and I've noticed most panels are somewhere in the 24 volt range. My question is, how do I size my panels with this battery? Will the 12v work for the 24 v panels?
