Dave Strenski, resident of Detroit exurb Ypsilanti, got it into his head that he would help the local food co-op reduce its bills by installing solar panels on its roof. And he didn't let his complete lack of experience with solar stand in the way. At this point, he's not only put solar on the roof of his co-op and four other buildings, he's also created his own system for monitoring its power output, and has turned his website into a hub for solar DIYers worldwide.
