Will my property value go up because of Solar Panels?

Yes, is the conclusion of three researchers at the Lawrence Berkeley National Laboratory, who looked at home sales — both homes with photovoltaic systems and homes without — in California over an eight-and-a-half-year period ending in mid-2009. The abstract of their study states, “the analysis finds strong evidence that California homes with PV systems have sold for a premium over comparable homes without PV systems.”

The premium ranged from $3.90 to $6.40 per watt of capacity, but tended most often to be about $5.50 per watt. This, the study said, “corresponds to a home sales price premium of approximately $17,000 for a relatively new 3,100-watt PV system (the average size of PV systems in the study).”

And the bottom line: “These average sales price premiums appear to be comparable to the investment that homeowners have made to install PV systems in California, which from 2001 through 2009 averaged approximately $5/watt.”
