There’s plenty of demand for Tesla Inc.’s Powerwall home-battery systems. The trick is finding installers that have them.

Only 12 percent of U.S. companies that install solar panels and residential batteries carry the Powerwall, a study Tuesday from Boston-based EnergySage and the North American Board of Certified Energy Practitioners found.
