Can you point us to a hospital or commercial datacenter that has solar and batteries and no fuel-based generator?
You would need solar generating capacity well in excess of demand (to serve the daytime demand AND fully charge the batteries on an overcast day to address a multi-day outage). That seems far less practical than a mechanical generator as backup.
