Silicon Valley Startup Prints $1/watt Solar Panels

GWBasic writes "A Silicon Valley start-up called Nanosolar has shipped its first solar panels — priced at $1 a watt. That's the price at which solar energy gets cheaper than coal. While other companies have been focusing their efforts on increasing the efficiency of solar panels, Nanosolar took a different approach. It focused on manufacturing. 'The company [has developed] a process to print solar cells made out of CIGS, or copper indium gallium selenide, a combination of elements that many companies are pursuing as an alternative to silicon.'" The outfit also happens to be backed by Google, a fact that's getting some attention at tech media sites.

    From the article: Roscheisen said the manufacturing process the company has developed will enable it to eventually deliver solar electricity for less than a dollar per watt

    I don't really know whether global warming is real and dangerous. Now just maybe I don't have to care.

    Can we conver Arizona with these (and use ultracapacitors for night power)? Please?

    This is a huge milestone. However, the summary gets a couple things wrong: First, $1/watt panels aren't "cheaper than coal". Large coal consumers buy 2,000 pounds of coal for $50. Burn that in a crappy Bush-endorsed power station, and utilities can print money at $0.07/KWh. That's why coal is the #1 enemy in the global warming battle - not oil. The $1/watt goal makes solar utility power feasible in areas that currently have excellent sunshine (say southern CA), and expensive fuel (say natural gas). It's a huge step, but not the last step.

    The second error in the summary is the current price. The company claims they could sell $1/watt panels, but with 100% of their production for 2008 already purchased, what are the odds they're selling their stuff 4X below market value? Not a chance. The revolution's happening, but it will take a while.
