Sun Number measures your roof, calculating the pitch, orientation, and size of each roof plane.
Sun Number calculates the amount of solar radiation for every square meter of your roof.
We add in local factors and compute your home’s Sun Number score that will range between 0 – 100.
If your home is suitable for solar, we can connect you to a local solar installer to design a custom system for your home, for free.
At Sun Number, LLC, we’re focused on increasing the public’s awareness of the solar potential of
buildings through our Sun Number™ Scores. Founded in 2012, we are the recipient of the U.S.
Department of Energy’s SunShot Incubator grant that enabled the development and initial
deployment of Sun Number Scores. Our goal is to increase solar installations by providing an
easy-to-understand assessment of a building’s solar potential and streamlining the solar
installer’s customer acquisition process.
