Sunrun Inc. is an American provider of photovoltaic systems and battery energy storage products, primarily for residential customers. The company was established in 2007 and is headquartered in San Francisco, California. Since its inception, the company has focused primarily on a power purchase agreement business model where Sunrun installs and maintains a solar system on a customer's home, then sells power to the customer at an agreed upon rate for a 20- or 25-year term. This business model allows property owners to install solar at no upfront cost, but without the benefits or some risks that come with being the owner of the system. The company has a sizable network of partners, including Costco and Lowe's, who allow Sunrun to market to customers inside their stores. In 2023, the company installed solar systems capable of generating 990 megawatts of power, and in the history of the company, had installed a total of 5.7 gigawatts of power for nearly 800,000 customers. In August 20, 2024 Sunrun surpassed 1,000,000 customers nationwide. Wikipedia
