New research sponsored by the Department of Energy 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.
The study, conducted by the Lawrence Berkeley National Laboratory in California, examined sales data for almost 23,000 homes in eight states from 2002 to 2013. About 4,000 of the homes had solar photovoltaic systems, all of them owned (as opposed to being financed through a lease with the solar company).
Researchers found that buyers were willing to pay a premium of $15,000 for a home with the average-size solar photovoltaic system (3.6 kilowatts, or 3,600 watts), compared with a similar home without one. Put another way, that translates to about four additional dollars per watt of solar power.Solar Energy Systems
For the average installation, the authors found that solar panels added a $20,194 premium to the sales price of the house based on repeat sales data (houses were in the mid-$500,000 range). Solar is really expensive to install—the average total system cost is $35,967, but the effective price to homeowners with subsidies including the federal tax credit is $20,892. Thus, homeowners appear to recover approximately 97% of their investment costs – in addition to the savings associated with reduced energy bills.
By contrast, a luxury kitchen remodel brings a 60% payback, according to Hanley Wood’s 2010-2011 Cost v. Value report.Solar Installations
