Hybrid storage of PV electricity

Hello everybody

I wonder what would be the efficiency of a following installation, in domestic self-consumption: PV panels produce current which must be consumed immediately. One storage possibility is the production of DHW.

Another possibility would be gravity storage by elevating a mass, like concrete blocks in a tower system used by a startup. But if instead of using concrete good old heavy lead batteries were used, they would be elevated or charged during the day and produced by gravity on descent, on demand or discharge at night or in case of bad weather. Knowing that the height would be limited to only a few meters.

To your calculators!

Thermal panels are more effective for this.

It's up to you to provide us with the figures. You will see that the potential gravity energy imposes enormous masses difficult to make profitable.
