Sunrun Inc.
Sunrun Inc. designs, develops, installs, sells, owns, and maintains residential solar energy systems in the United States. The company sells solar energy systems and products, such as panels and racking; and solar leads generated to customers. It offers battery storage along with solar energy systems; and sells services to commercial developers through multi-family and new homes. Its primary customers are residential homeowners. The company markets and sells its products through direct-to-consumer approach across online, retail, mass media, digital media, canvassing, field marketing, and referral channels, as well as its partner network. It also operates distributed electricity power plants. Sunrun Inc. was founded in 2007 and is headquartered in San Francisco, California.
What does it do?
Sunrun puts solar panels on people's homes — and then lets homeowners either buy the system outright or simply pay a monthly bill for the electricity it produces, like a utility. Think of it as swapping your power company for Sunrun. The company handles everything: design, installation, and ongoing maintenance. It operates across more than 20 U.S. states and is the largest residential solar provider in the country.
Electricity prices keep rising, and millions of Americans are looking for ways to lock in lower, predictable energy costs — Sunrun sits right at that intersection. The push toward clean energy, combined with federal tax incentives from the Inflation Reduction Act, means the market Sunrun operates in is being actively subsidized by the U.S. government right now. With a $3B market cap, it's small enough that a shift in momentum could move the stock significantly.
How does it make money?
Sunrun makes money in two main ways. First, it sells solar systems directly to homeowners who want to own their panels outright — a one-time transaction. Second, and more importantly, it signs long-term contracts (typically 20-25 years) where it owns the panels and the homeowner pays a monthly fee for the solar electricity generated — this is called a Power Purchase Agreement or lease. This recurring revenue stream is the core of the business. Revenue grew from $2.0B to $3.0B in the latest year, a 50% jump, showing strong demand.
Why do investors care?
The growth story is simple: solar adoption in the U.S. is still relatively low, which means there's a huge untapped market. Sunrun's subscription-style model — where customers pay monthly rather than upfront — lowers the barrier for homeowners who can't afford a $20,000+ system. If Sunrun can keep growing its base of long-term contracted customers, it builds a predictable revenue stream that compounds over time. The big thing that has to go right: interest rates need to come down, because Sunrun borrows heavily to finance the panels it installs and owns.
