As an increasing number of homes add solar power, the Solar Energy Industries Association (SEIA) offers a way to determine the value of a solar system on a residential property. A new guide, How Owning a Solar System Impacts My Home Value: A Guide to Valuing Residential Solar Energy Systems, is aimed at helping consumers receive an accurate value estimate when buying or selling a home with solar. The guide, , walks consumers through the various methodologies that professionals use to value a solar system and provides homeowners with tips along with a recommended valuation method. “It’s critical both buyers and sellers go into a home sale well-educated, armed with the facts and figures needed to feel confident in their solar investment,” said Abigail Ross Hopper, SEIA’s president and CEO. In the guide, SEIA advises readers to focus on the projected income a solar system will generate for the owner over its expected lifetime. According to a recent study by Sandia National Labs and Energy Sense Finance, that approach is typically used to determine value in home appraisals in major solar markets.
