84 Million Homes on Zillow Now Show Solar Potential of the Home

Sun Number and Wave Solar announced today that 84 million homes on Zillow now include a Sun Number score, which shows the potential solar generation of the home. This information helps millions of homeowners understand their options for going solar.

“Home sellers and buyers that have not had Sun Number scores previously have been contacting us asking how they can get a Sun Number score for their home,” said David Herrmann CEO of Sun Number. “The expansion of Sun Number scores to 84 million residential buildings on Zillow means many of those homeowners, sellers, and buyers have a simple way to access this useful information.”

Sun Number uses multiple datasets to analyze an individual home’s solar potential, taking into account the angle of the roof, the direction the home is facing, the solar radiation potential of the roof, and local electricity rates. Sun Number’s algorithm ultimately assigns a score to the home between 0 and 100, estimating how much the homeowner would stand to benefit if they went solar.

“This data is important for the millions of people participating in the U.S. market shift towards solar energy,” said Colin James Walsh, CEO of Wave Solar. “With the Sun Number scores on America’s most popular real estate site, homeowners will have more data to make an informed decision, and solar installers will see even more interest in their product.”

The Sun Number score is included on 84 million homes on Zillow under the “Utilities, Green Energy” section of the page. Sun Number scores were first added to millions of homes on Zillow in August of 2016 and the 84 million homes on Zillow are live now, including a majority of homes for the first time.

“We are very proud of our proprietary scoring system, which was developed as part of the Department of Energy’s SunShot initiative,” added Herrmann, “By bringing these different solar-relevant datasets together into one easy-to-understand score, we allow homeowners to see if they should be exploring solar as an option for their home.”
