I have been meaning to write this post for quite some time now. Andrew's parents have now gone solar. All of their household energy comes from these new, glorious solar panels.
They had to remove some trees so the panels could get full sun in the front yard. They went through this company (http://acroenergy.com/) so don't forget to mention the Hursts when you order your own set. I don't know all the statistics, but I think they said that they will break even somewhere like five years down the road. Green In-Laws are the best.
