Start-up: Affordable solar power possible in a year

A Silicon Valley start-up says it has developed technology that can deliver solar power in about a year at prices competitive with coal-fired electricity, a milestone that would leapfrog other more established players and turbocharge the fast-growing industry. SUNRGI's "concentrated photovoltaic" system relies on lenses to magnify sunlight 2,000 times, letting it produce as much electricity as standard panels with a far smaller system. Craig Goodman, head of the National Energy Marketers Association, is expected to announce the breakthrough Tuesday.
