There's a Solar in my Eye!

The HOA is thinking about getting solar panals for the Common Areas. This sounds so cool. I'm not so sure how it will play out as it took them 6 months to repair my roof after it collapsed into the 2nd bedroom  in 2007. Oh yeah remind me to tell you guys that story. It ends with a bad texture job, a new roof, a new ceiling (without popcorn) and, new supports on the roof as they had mostly rotted!!!

Anyone out there have any experience with solar? The HOA is talking about letting the homeowners get solar panels as well and it's worht looking into right?
