Home Solar Financing Pioneer Receives Backing from Accel Partners.

SAN FRANCISCO - July 28, 2009-

SunRun, the leading provider of home solar power, today announced it closed a Series B round of funding for $18 million led by Accel Partners and joined by existing investor, Foundation Capital. SunRun plans to use the funding to meet strong demand for its popular residential solar service, expand into new markets, and build on the Company's recent successes.

The Company has experienced rapid growth since its founding in early 2007, marked by expansions outside of its initial California market and into Massachusetts and Arizona in early 2009, and has achieved 300 percent growth this calendar year alone. This funding round follows U.S. Bancorp's commitment in November 2008 for project financing for up to $105 million in solar facilities and a $12 million Series A financing led by Foundation Capital in June 2008. Rich Wong from Accel will join SunRun's Edward Fenster and Lynn Jurich, Charles Moldow from Foundation and David Buzby, also Chairman of SunEdison, on the Company's Board of Directors.

SunRun makes it affordable and turnkey for homeowners to switch to solar power by delivering immediate savings on utility bills with minimal start-up cost. For as little as $1,000 down, SunRun will arrange to purchase customized home solar equipment from an authorized local solar contractor and then sell the solar electricity at a fixed, discounted rate to the homeowner's current electricity bill. Over time, as utility rates increase, the homeowner accumulates significant savings.

"Getting solar is one of the most important things homeowners can do to make a positive impact on their local environment and monthly expenses," said Ed Fenster, CEO of SunRun. "Most people don't have $30,000 to spend on solar equipment or want to worry about taking care of a $50,000 asset. SunRun makes solar a reality for people who wouldn't otherwise have considered it, and we're finally at the point where it makes financial sense as well as environmental sense for a majority of homes.'

CEO Edward Fenster and President Lynn Jurich started SunRun as classmates at Stanford's Graduate School of Business with the mission of making renewable energy both affordable and economically viable. The Company's first system was on the roof of Edward's home in San Francisco, and today SunRun provides solar electricity to more than a thousand customers.

The Company's unique approach includes partnering with locally-based solar companies that help generate local green jobs. SunRun carefully selects high quality installers in each of the markets it serves. As demand for SunRun's service grows, so do jobs with SunRun's local installation partners.
