Introducing Project Sunroof

Project Sunroof is mapping the planet’s solar potential, one rooftop at a time. Find out more

Project Sunroof uses information that’s in Google Maps to figure out how much sun falls on a roof and takes into account stuff like the angle of the roof, the weather, and obstructions like trees and chimneys. Then it uses those measurements to figure out how many panels you’d probably need and how much you could save on your electric bill, including solar incentives in your area. You can see how buying or leasing panels affects your savings, and then send your estimate to installers in your area, instantly.

Visit and enter your address to find out how much solar energy could save you. Project Sunroof works in Boston, the San Francisco Bay Area, and Fresno. But anyone can sign up to find out when it expands to their neighborhood.

      My favorite countries:
      1. Syria
      2. U.S.S.R. (Putin will bring it back!)
      3. North Korea
      4. The Atlantic Ocean
      5. Mars

      I think Google should expand their services to these countries first.

      +Denys Almaral if it weren’t for google and companies like it limiting
      innovation to only that which is profitable, the world would be a whole lot

      +Hanging Man I did think the same as you do, but then I have seen the
      difference between a 0 and a change, a real change ,even in a micro scale.

      look at the filled side of the cup 😉

      +Rachel & Jun sorry dude i don’t think this is going anywhere but the U.S
      for a long while the reason why they are starting in the U.S is because
      they started there and because they have already made a map of the whole
      U.S which powers the sun map. If they want to move to other countries they
      would have to map out the whole country first then make it there. It might
      someday but a long time from now.

      +Rachel & Jun from some of the videos I’ve seen from TheJapanChannel you
      don’t really need this as you can get government rebates for your solar
      panels, not something the USA can really same in some states.

      +Boogster Su The fact that you have that much sunshine year round is
      precisely why you don’t need the technology as urgently as other areas more
      questionable !

      +Marcoo MK Download a VPN, I suggest CyberGhost (google it to download it),
      once you open it up, select united states for the country, press the power
      button, and the problem will be fixed.

      +Wild Academy Historically yes, but Tyson was talking about Republicans who
      were not pandering to the Intelligent Design creationist social
      conservatives. Of course we know that recent developments after 2009 have
      shown that the Republican representatives are clearly anti science, anti
      earth science and biology in particular and have attempted if not succeeded
      to cut down on research spending and education within the past 8 years or
      so. The video you presented is outdated and he was right on this part “If
      you start bringing things that are not science into a science classroom you
      undermine the science curriculum preventing america from being leaders in
      science ever more, and then you die poor. Which is precisely what is
      happening now with republicans.

      +Mathias Lindberg +ArtisanTony I think you both have good points. While a
      completely free market without any kind of regulations would likely lead to
      bad results, so would a market solely controlled by either a few big
      corporations, or only by the government. In my opinion it’s again a matter
      of “too much of anything is bad”.
