Yes, generally, solar panels add value to a home. Homes with solar panels sell for approximately 4.1% more than homes that don't have solar panels, according to Zillow. On a $400,000 house, this amounts to an extra $16,400
However, this also depends on the market. In certain areas, homes may have a much larger markup than homes in other areas of the country. For example, in the New York City metro area, homes offer a 5.4% return with solar panels.
