Perhaps shaving a small portion of your bill is possible but the up front costs are prohibitave. Furthermore there are ongoing costs. Those batterys arent cheap and they dont last forever. One good lightining strike can put you back to square one also. Yes there are ways to guard against that as well but more costs and there not gaurenteed, lightning finds a way sometimes.
If you really wish to save money / energy with solar again water heating is the best route at this time. Its passive, its reletively inexpensive, it works, and very rarely fails which is more than can be said about photo voltaic.
There are also systems that can use some of this heated water pumped through tubing in your floor for a nice space warming system. But that has to be designed from the ground up.
Forget trying to run an electric strip heat on a pv system... out of the question.
