Sunrun Inc.

Sunrun Inc. is an American provider of residential solar energy systems, battery storage products, and energy services. Founded in 2007, the company's mission is to create a planet run by the sun by enabling U.S. homeowners to lower bills, gain resilience, and participate in clean-energy markets through solar, battery storage, energy management, and financing options. Its corporate headquarters are located in San Francisco, California.

Sunrun offers integrated residential solar energy systems, primarily through a "solar-as-a-service" model that includes leases and power purchase agreements, alongside outright system ownership. Key offerings include solar panel installation, battery energy storage solutions like Brightbox, and energy management services. The company is also actively developing Virtual Power Plants (VPPs) to enhance grid stability and enable customers to participate in energy markets. Sunrun primarily serves residential customers across the United States, with a strategic focus on markets with high demand for energy storage, such as California and Puerto Rico.

As of early 2026, Sunrun holds a leading position as the largest U.S. residential solar provider by cumulative deployments, serving over 950,000 customers with more than 6 GW deployed. The company reported strong financial results for Q4 2025, with revenue increasing 124% year-over-year to $1.16 billion, and full-year 2025 revenue reaching $2.975 billion. Recent market analysis in late 2025 suggested Sunrun was well-positioned for market share gains in 2026, partly due to the expiration of certain tax credits favoring its third-party ownership models. However, despite strong performance, Jefferies downgraded Sunrun to a "Hold" in March 2026, citing a cautious outlook for the year.
