Sunrun is a company that provides low-cost residential solar power by leasing solar equipment to customers. As of 2014, Sunrun offers solar services in Arizona, California, Nevada, Colorado, Connecticut, Hawaii, Massachusetts, Maryland, New Jersey, New York, Oregon and Pennsylvania.
According to Sunrun, buying and installing a solar system costs a homeowner between $15,000 to $60,000, as of 2014; however, with Sunrun's lease or power purchase agreement, customers pay a fixed rate for the electricity produced, not for the equipment, installation or maintenance. Sunrun offers a locked-in rate for up to 20 years.
Sunrun first offered a solar power purchase agreement in 2007. As of 2014, Sunrun provides solar services to over 60,000 customers.
