Translated to a workable prototype by GP designpartners, the 2.31kw Smartflower system claims to provide a plug & play power source that takes just an hour to set up. For 10,500 euros (roughly $11,759), consumers in Europe can pick up this 750 kilogram (1,653 pound) system that works with bi-axis suntracking and GPS coordinates, generating roughly 45 percent more power than a typical rough system set at a 30 degree angle. According to Linnea Nilsson, the company plans to expand into the United States next year.
I use so little power that even with the tax credits, even if I could afford a system, it would take me a long time to amortize the net cost.
I've heard of people installing solar systems and instead of saving them money it ended up costing them more than they were paying the electric utility company, after accounting for the amortized cost of the equipment over its not as long as they had hoped lifetime.

For peak demand, like running a central air conditioning unit, yes.
It's 2.31kw which could be exceeded with things like that or an electric stove, but I read somewhere the typical average residential usage is about 1kw, so if you could figure out a way to avoid those large peak demands, you might be able to get by with one, especially if the house is small.
I use batteries for computer backup when the power goes out and they don't last long. I think I'd need a whole bank of batteries to last from dusk to dawn, especially in the winter when days are short and nights are long.

You level the demand and the intermittent supply by using a battery.
It's a very novel idea. I wonder why someone hadn't thought of this sooner. What says ATS?
While most 13-year-olds spend their free time playing video games or cruising Facebook, one 7th grader was trekking through the woods uncovering a mystery of science. After studying how trees branch in a very specific way, Aidan Dwyer created a solar cell tree that produces 20-50% more power than a uniform array of photovoltaic panels. His impressive results show that using a specific formula for distributing solar cells can drastically improve energy generation. The study earned Aidan a provisional U.S patent – it’s a rare find in the field of technology and a fantastic example of how biomimicry can drastically improve design.
