    To support a 20 Kw solar panel system the battery would have to be as big as a car if not larger. You would need an addition to your home to house them.

        No 16 to 20 KWh I think?. Not even the Telsa Roadster has a battery that size. Using an LFP battery at $1.20/wh would be silly at 50 Kwh. Battery prices and energy density are the show stoppers for EV's. Obama's dream of 1,000,000 EV's is just that, a nightmare of a dream for taxpayers. who are actually paying for them.

            Well there are quite a few folks where money is no object. However most of those types of folks would not waste it on something like solar battery systems.

              to be honest and fair the guy had multiple array's and not all of it fed the batteries. This was a hybrid grid tied system with a large generator also.
