Ok. First. Let me just say that I'm all for the grid and I think it's needed for most cases. However. If you're looking to get off, is not a water tank + smaller battery.
Here's my thought:
Typically when your solar array is not being used by your home you feed your power back to the grid. Great. But what if you used it to pump water (from a well) into a water tank/tower that is hooked to a turbine. This turbine charges a battery that holds a constant source of power for the home.
Someone debunk this from a physics perspective. I don't understand why you can't have power 24hrs a day with instant kinetic energy from a gravity fed water turbine.
