You would have to have a rotating solar array, or a roatating solar home like this:

If you didn't have an active array that could track the sun, you'd have a very short window of full power and need way more panels than would make sense, ugly and very expensive panels all over facing different directions...
You wouldn't have to store the energy I don't think... When you create more power than you use the electric company is paying you for the extra, and then when the sun isn't enough you pay the electric company. Given enough cells, you could grow AND collect money from the electric company at the same time, but there are solar panel breakthroughs in late stages of development right now, who knows if 5-10 years from now things could be a whole lot cheaper and a whole lot more efficient. Obama seems determined to push this job creation stuff towards solar etc and options and prices are bound to change dramatically with economies of scale.
