Sunrun

Sunrun is America's largest provider of residential solar, battery storage, and home-to-grid power plants. Founded in 2007, it pioneered the no-upfront-cost solar subscription model and also offers leases, PPAs, loans, and outright purchase. It installs and maintains home solar and battery systems for over a million customers, backed by the Sunrun Guarantee, and operates an online shop for portable power and home energy products. It also aggregates its networked home batteries into Distributed Power Plants that provide dispatchable grid services to utilities and grid operators.
