I don't know the math that is used, nor do I know much about solar, but the way you asked the question causes me to hazard a guess at a week or more to charge that 60 KW/HR battery in that weather. However, here in the desert of So. Cal, I imagine that same array would cut the charge time in half (very few cloudy days here even in the dead of winter). Again, just a wild guess.......Rich
