Interesting read, but until the storage aspect (solar batteries for night+inclement weather alone cost over 7k for a typical home) and actual installation costs (can cost as much as a standard roofing job just to have them put on your house) come down, the systems will always be cost prohibitive compared to coal or NG.
They better come up with a way to store the energy, because that is the biggest drawback of solar and wind. Also, it is MIT, not China, who are developing solar that could break the 35% efficiency barrier.
We invent technologies, China only copies it. Capitalism at work.
I was going to build my solar system when the cost of core output (from the panel) was running $2.50 per watt, but I waited and now it's .75 per watt. Now I'm ready to go with Xantrex 2800 staring at me.

@Kreutz it's like our minds are on a wire
The following solar power plant powers 30,000 households, and produces electricity 24 hours a day. It heats up a melted salt solution during the day, and the heated salt powers a turbine at night.

Oh yea? The Spaniards found out it wasn't so cheap after all.............
It has been a chastening experience. The government failed to cut subsidies when renewables were booming, so the cuts have had to be draconian. It imposed no cap on new capacity and stood by while that grew uncontrollably (this also happened in Germany). The promised jobs have vanished. The solar-energy business has lost tens of thousands of jobs from its peak. And after repeated retroactive cuts no one is willing to invest in renewable energy any more. Yet because projects often receive subsidies for 20 years, the costs remain. Even after the cuts, renewables subsidies are running at €7 billion-8 billion a year. It is not hard to think of better ways of spending such large sums of taxpayers’ money
