Those don't sound like inexpensive materials to build with, not to mention I believe Nanosolar is in competition for the same elements for their thin film panels.Each of the company's cylinders is actually two glass tubes, one nested inside the other. Rather than silicon, the solar cells use a mixture of copper, indium, gallium and selenium deposited on the inner tube.
The Arizona Department of Commerce and Albiasa Solar of Spain will announce Monday a $1 billion solar-thermal power plant will be built near Kingman next year, generating enough power for 50,000 homes at once when it opens in 2013.

Solar-thermal power plants don't use the common black panels to make electricity. Instead, they use mirrors to focus sunlight on liquid-filled tubes. They use the hot fluid to make steam and spin turbines, much like coal, natural-gas and nuclear plants operate, but without the need for fuel.
That's what most folks tend to think... but that's normally because they don't take all the benefits into account. I can't think of many other investments that immediately and consistently pay you back - tax free - just about forever. The folks who took out some investment money to buy their PV systems last year - couldn't image a better investment. Most folks found more of their money vaporized than they paid for their systems.The time to payback is a bit long right now for most folks, I think.
You and me both, brother!I think people are nuts for not installing solar PV systems.

I can't remember the name but there is a company that will install panels for you with no upfront costs, you just lock in a monthly rate with them for a contracted period of time.
Neat, but some obvious short comings. The poor efficiency will be even worse on a vertical surface, and the lifespan will have to increase dramatically before anyone starts building them into windows.
Startup Enphase Energy of Petaluma, CA, is now making the first micro-inverters. These smaller inverters can be bolted to the racking under each solar panel, to convert DC power into AC for each panel individually. The company claims that the devices will increase a PV system's efficiency by 5 to 25 percent and decrease the cost of solar power.
Home solar systems - Residential solar power by SungevityLast year, Sungevity added a page to its Web site that lets prospective customers plug in their home addresses and see how much various solar panels would cost and how much energy they could save over several years.
A Sungevity engineer can calculate these costs in about 10 minutes with help from Microsoft's Virtual Earth - mapping software that helps him visualize the length, width, pitch and orientation of a roof and how much sunlight it can get.
