Despite growing prevalence of rooftop PVs, MLS usually doesn’t include solar power information

More and more homeowners have added solar panels to their roofs—over one-quarter of the roofs in a few California neighborhoods, for instance, have PVs. But the standard tool for finding homes on the market, the Multiple Listing Service (MLS), typically doesn't include information on solar power.

The average buyer today is more educated about the value of solar power, but few understand the nuances of leasing the equipment versus buying it, and the same is true of many real estate agents. Owning the panels is more valuable to the homeowner than leasing them.
