You know how residential towers and office buildings are not always good candidates for solar power?

Meanwhile urban grids are being over-supplied with peak solar on a regular basis.

What if gravity/water storage was powered in urban areas using the excess solar. Small scale units to retrofit existing towers. Distributed storage.

I wonder how much energy storage can be built without needing to make batteries? What scale of power can realistically be drawn from gravity fed flow?
