If I'm not mistaken, all spolar set ups (except passive water heaters) rely on battery banks. i wanted to talk to the owner, but he wasn't available, just the guys that installed the decorations, and they seemed pretty clueless as to the setup.

PV solar doesn't require battery banks unless you want to be off the grid or want the back up power.
A very high percentage now just dump excess power into the grid while they are generating.
