Solar Home for Sale


Solar Home For Sale

By now, most people know that a residential solar system can help the environment and save the homeowner money on electricity bills. However, here’s some more good news! New research sponsored by the Department of Energy through the SunShot Initiative shows that buyers are willing to pay more for homes with rooftop solar panels — a finding that may strengthen the case for factoring the value of sustainable features into home appraisals. According to a study by Zillow in 2018, “homes with solar-energy systems sold for 4.1% more on average than comparable homes without solar power.” While the exact increase in value depends on a number of factors such as the average hours of sunlight in the location, local electric rates and the local popularity of solar, a figure close to 4% should be expected in most cities nationwide.

The Lawrence Berkeley study also found that homes equipped with solar panels tend to sell slightly faster than similar homes without them. The housing market is driven by the same factors as every marketplace — supply and demand. More and more prospective home buyers want a residential solar system as part of their next home. If your house has one and the other houses in your area do not, buyers will look first at your house and be willing to pay more to purchase it.

CNBC reports that more than 1.3 million U.S. homes had solar installed in the U.S. by the end of 2016. “Previous studies on PV home premiums have been limited in size and scope,” says Ben Hoen, the lead author of the Lawrence Berkeley reports, “We more than doubled the number of PV home sales analyzed, examined a number of states outside of California, and captured the market during the recent housing boom, bust, and recovery.”
“As PV systems become more and more common on U.S. homes, it will be increasingly important to value them accurately, using a variety of methods,” says co-author Sandra Adomatis, an appraiser who helped develop the Appraisal Institute’s Green Addendum. She noted, “Our findings should provide greater confidence that PV adds a quantifiable premium to a wide variety of homes in California and beyond.”
The growth in home PV systems means realtors need reliable methods to value these homes appropriately. The solar market is still young and many real estate appraisers are not informed about the value of a rooftop solar system, and what it adds to a house. However, Gerard O’Connor, an appraiser on Long Island, says Fannie May has just amended its rules to allow appraisers to include the value of a home solar system when doing a home appraisal. That one change could help boost the number of home solar systems on American homes substantially.
