Sunrun and Toll Brothers have an exclusive agreement for Sunrun to provide solar power as an included feature in all Toll Brothers homes in California, as well as a preferred agreement to provide solar for additional Toll Brothers divisions nationwide.

As part of the agreement, Sunrun will serve as a "one-stop shop" to provide solar as a standard feature in all Toll Brothers communities in California, including sales, design, permitting, installation, customer care, and warranty. Sunrun also provides home buyers with the choice of a third-party battery storage system, including EnPhase or the Tesla Powerwall 3, to integrate with their provided residential solar system.
