As if getting a great return on investment, decades of savings on energy costs, and being part of the renewable energy revolution weren’t enough to convince you to consider getting a home solar PV system, remember that going solar can also be a great way to increase your property value. And we’re not just saying that because we love solar, because a recently released study, the largest of its kind, backs that up with data.A team of scientists, led by the U.S. Department of Energy’s Lawrence Berkeley Laboratory, and in partnership with Sandia National Laboratories, found that homebuyers have been consistently willing to pay a price premium for homes with “host-owned” solar PV systems installed, including both new homes and older homes.
The study, which analyzed about 22,000 home sales, just under 4,000 of which were solar homes, across 8 states between 1999 and 2013, showed an average price premium of about $4 per watt of installed solar PV, with an average price premium of about $15,000 for a solar home with a typical system (3.6kW) installed. “Previous studies on the value of home solar to home prices have been limited in size and scope,” said Ben Hoen, the lead author of the study, and Selling Into the Sun: Price Premium Analysis of a Multi-State Dataset of Solar Homes analyzed more than double the amount of home sales, as well as “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. Our findings should provide greater confidence that PV adds a quantifiable premium to a wide variety of homes in California and beyond.” – appraiser and co-author Sandra Adomatis
Not only is this good news for those looking to sell their solar home, but it’s also another reason to consider investing in a home solar PV system, even if you aren’t sure that you’ll be there for the long-term. With a home solar system, you can not only get electricity cheaper than the grid, but you’ll also have the confidence in the long-term value of the initial investment, whether you stay there or sell the home.
Another good piece that may come out of this study is that with the rising number of solar homes in the US, there is also a growing need for an accurate and reliable appraisal or valuation for homes with solar PV, so the real estate industry has a standard to work from and is comparing apples to apples, so to speak. While the study does credit appraisers, agents, and others in property valuation with making strides toward accurately valuing solar PV homes, in the conclusion, the authors suggest that further analysis on any specific markets, as well as collecting and analyzing data from other states, “would be beneficial” to helping to establish accurate home price premiums.
