After a "mental walk-through" counting watts, it appears that, more or

of continuous power would do us (if we turn off all unnecessary lights
and don't use the furnace), and that suggests something like 50 square
meters of solar panels to charge up during the day and something
approaching 20 automobile batteries to carry the house through the night.
First, don't use automobile batteries. They are not designed for deep
discharge cycles. Golf cart batteries are a better choice.
Also, don't forget that, while your power source only needs to meet
your average demand, your inverter must meet your peak demand.
Finally, you might want to get in line for some of the first
nanotechnology solar cells:

which will reduce your cell cost significantly.
Right -- even if one only waits for them to come onto the market and
then buys conventional panels, they could push the cost of
aforementioned conventional panels down just by being there as competition.
