First Solar

I read a short article/profile on First Solar in the Wall Street Journal - Best 1-Year Performer: First Solar. Stock price has gone from $20 since their Nov. 2006 IPO to now $219. And the Walton family (WalMart) has been funding it since the beginning. The technology they are using is different than the normal silicon (in short supply) that most solar companies are using, it's cadmium tellurium. Trade off is lower efficiency, but it's available. CIGs (copper indium gallium selenide) is another material for solar that may reduce cost and is what is being called nano, since it can be sprayed on.
