Each one of these smaller panels (18"x24") that makes up the larger panel cost about $600.
We stopped to talk to these ComEd fellas on Saturday during the Humbolt Park Earth Day Event. Solar is really interesting, and becoming less prohibitively expensive. I think that wind power has some serious potential here in Chicago. Coupled with solar and net metering, a difference could be made.
I ask all my Flickr friends to not get too greenwashed, but stay mindful of their energy usage and keep all the alternatives in mind.
Thanks to Brian for the iPhone pics.
