Sunrun is the largest residential solar and battery provider in the U.S., founded in 2007 and headquartered in San Francisco. The company pioneered the “solar-as-a-service” model with power purchase agreements (PPAs) and solar leases that require little to no upfront costs. Sunrun has installed nearly 6 GW of solar capacity across around 1 million homes, and continues to expand with integrated battery storage systems like Brightbox (Tesla Powerwall or LG Chem). Their offerings now include innovative financing like the Sunrun Flex plan, designed to adapt payments to household energy usage over time. The company also provides smart electrical panels, EV charging integration, and grid services through managed home energy assets.
