Hm. My car battery is about 600 WH and costs about $30. I think you'll
find the economies of scale that car battery manufacture has to be
very hard to beat. So you'd need to invest about $500 in the
battery array. Not too bad, but you also need the inverter
and power management electronics. I guess the cost of the solar
array will be the dominant factor.
