Sunrun is America's leading residential solar and battery storage company. Founded in 2007, it offers homeowners solar energy with little to no money down, so that customers pay only for the clean energy their systems produce rather than making a large upfront purchase. The company operates across the United States and has served nearly 800,000 customers, deploying 5.7 gigawatts of clean energy capacity. In 2020 it acquired Vivint Solar in a deal valued at $3.2 billion.
The company's technical work spans residential solar energy, battery energy storage, distributed energy resources, grid services and virtual power plants, and solar financing and energy-as-a-service models. Home battery installations provide backup power during outages and support the broader grid during periods of peak demand. A vision of a decentralized energy future - in which homes function as distributed power plants - underpins this activity.
Sunrun is vertically integrated, providing consultation, installation and maintenance as a single service. This structure gives the company control over the customer experience and long-term system upkeep. It pioneered the little-to-no-money-down solar model, with a stated mission of making solar accessible to everyday families rather than treating it as a luxury purchase.
