Learn Instantly if Your Property Could Benefit From Solar Energy

Sun Number is makes it possible for Denver homeowners and commercial property owners to instantly learn how much they can benefit from rooftop solar using a free online tool.  This free service is available for more than 800,000 properties in the Denver metro area, including suburbs such as Broomfield, Brighton, Westminster, Aurora, Lakewood, Highlands Ranch and others. The Sun Number analysis of the Denver metro area has determined that if solar panels covered all of the solar suitable square footage of Denver metro rooftops enough electricity would be generated to power the city of Denver and all of adjacent Jefferson County.

Enter your property’s address at the website, and you can immediately get an analysis of the amount of solar energy the building’s rooftop can generate and how much money that would save in utility costs. This analysis provides you with information that was previously only available through a lengthy on-site analysis by a solar professional.This free service is available for more than 800,000 properties in the Denver metro area, ranging geographically from the Boulder/Longmont area down through Denver itself and to southern suburbs like Highlands Ranch and Parker.


The online tool provides a Sun Number Score between 1 and 100 to help you easily understand your solar potential and how it compares to the regional average. The tool also provides an estimate of the dollar value of electricity that could be generated by a solar installation, and makes it possible to begin a dialogue with a solar provider if that is of interest.

After you get your score you can go to our member database to find a local solar provider.

Don't forget to explore the benefits of energy efficiency investments! You can make your home more comfortable and save money by investing in insulation and air sealing first.
