Sunrun Inc Dossier
Qualitative Analysis
Business overview
Sunrun Inc. is the leading provider of residential solar, battery storage, and energy services in the United States. Founded in 2007 and headquartered in San Francisco, California, the company pioneered the solar-as-a-service model. Under this model, Sunrun designs, installs, and maintains residential solar energy systems, selling the generated electricity to homeowners under long-term power purchase agreements (PPAs) or solar leases typically spanning 20 to 25 years. This capital-intensive business model generates highly predictable, recurring, and contracted revenue streams over multiple decades. In addition to its core solar-as-a-service offerings, Sunrun sells solar energy systems and products directly to customers, operates distributed power plants, and collaborates with major retail partners like Costco and Lowe's to expand its customer acquisition platform.

Expected impact: Improves customer experience, provides better operational control over regulatory complexity, and yields higher margins and stronger customer credit profiles.
Scaling Virtual Power Plants (VPPs) and grid services to monetize networked batteries by dispatching energy back to the grid during peak demand.
Expected impact: Generates recurring, capital-light cash flows independent of new customer originations and enhances grid reliability.
