All those homeowners who have been installing residential solar panels over the last decade may find it was a more practical decision than they thought. The electricity generated may have cost more than that coming from the local power company (half of which, nationwide, comes from burning coal), but if they choose to sell their homes, the price premium they will get for the solar system should let them recoup much of their original capital investment. (...) Homeowners who install solar on existing houses get nearly three times the premium of homeowners whose house came with solar panels. The study speculates about the reasons, suggesting that “new home builders may also gain value from PV as a market differentiator, and have therefore often tended to sell PV as a standard (as opposed to an optional) product on their homes and perhaps been willing to accept a lower premium in return for faster sales velocity.”More details at the Lawrence Berkeley National Lab site:
