Sunrun

Sunrun Inc. (NASDAQ: RUN) is a United States-based provider of residential solar electricity and operates the "second largest fleet of residential solar solar energy systems” in the United States. Headquartered in San Francisco, California and founded in 2007 with a focus on home solar power installation, financing and leasing, Sunrun pioneered the use of solar as a service for residential customers and in some states offers customers either a lease or a Power Purchase Agreement (PPA) business model, whereby homeowners pay for electricity that their solar panels produce but do not have to buy solar panels outright. Sunrun has a number of service packages. The BrightSave option lets a customer lease a solar system for their residence, while the BrightBuy option allows a customer to directly purchase a system from Sunrun. BrightAdvantage allows a customer to finance their system through a loan.

Sunrun acquired the residential solar division of REC Solar, a subsidiary of Mainstream Energy, in early 2014, which allowed the company to directly install systems and become "more of a full-service home solar supplier." They also acquired SnapNrack and AEE Solar. In October 2014, the company officially debuted its Sunrun Partner Program to develop its network of installation and sales partners. In 2015 Sunrun acquired the "consumer demand generation" company Clean Energy Experts (CEE), with CEE billed at the time as the "largest lead generation company in the solar industry." Sunrun completed their IPO in 2015, raising $251 million in August. Sunrun currently has approximately 100,000 solar customers in fifteen states.
