I live in colorado and it says i would lose money by going solar. Interesting since at costco, etc the solar guys are pushing pretty hard. I've held off so far because I think there's still room for dramatic improvement in solar panel and battery technology in the next few years.

Also I seem to get a new roof every 5 or so years due to all the hailstorms we get around here. I suspect solar panels don't like big hailstones very much and I have no idea what would happen if both the roof and panels are damaged. I doubt a roofing company is well equipped to handle the panels.
