Hail storm may have killed my solar...

I can report that while gone on a trip the battery did charge up. I still think it's acting, well, differently than it has, even in the recent past. 

I've ordered a 120W folding solar panel for times, upcoming soon, when trees will be problematic for the system. My question now is whether it's best to use two charge controllers or one, larger charge controller for what will be two different panel systems, if that even matters. Any guidance would be appreciated.
Thanks-
Peter
