Sunrun and Mainstream Energy Corp. announced that Sunrun has acquired the residential division of REC Solar, AEE Solar and SnapNrack. The companies represent Mainstream Energy’s residential solar sales, design and installation; wholesale distribution; and mounting systems and hardware businesses, respectively. In the commercial market, REC Solar will continue as an independent organization under the legal name REC Solar Commercial Corp. The value of the transaction was not disclosed.

“Sunrun pioneered solar service to remove the most significant barriers to going solar. We continue to innovate our business to further drive down costs, increase quality and broaden our reach to consumers so more homeowners have access to affordable home solar,” said Lynn Jurich, Chief Executive Officer of Sunrun. “The residential solar market is growing rapidly and this acquisition marks the next step in our multi-channel growth strategy. REC Solar’s residential division, AEE Solar and SnapNrack complement our thriving channel business and further enable us to fulfill the enormous market potential for home solar nationwide.”

REC Solar is a huge manufacturer of solar electric system design and installation, with more than 11,000 customers across seven U.S. states. Since becoming Sunrun’s first installation partner in 2007, REC Solar has helped thousands of homeowners elect solar energy with Sunrun’s solar service, which allows homeowners to pay a low rate for clean energy and fix their electric costs for 20 years.

“REC Solar is the industry leader in customer satisfaction and high quality construction, while AEE Solar and SnapNrack bring capabilities that allow us to make solar energy affordable for more consumers, provide superior systems and service, and lay the foundation to become a major energy company,” Jurich said.

Under the terms of the acquisition, Sunrun will expand its executive leadership team. Lynn Jurich will lead the company as Chief Executive Officer, while co-Founder Ed Fenster will continue in his operating role under the new title of Chairman. Tom Holland assumes the role of President and will guide the company’s strategy and execution. Mainstream Energy CEO Paul Winnowski joins Sunrun as Chief Operating Officer and Timothy Ball, Chairman of Mainstream Energy Corp., will join Sunrun’s board of directors.

“Mainstream Energy and Sunrun have always been perfectly aligned in focusing on customers, maintaining high quality and driving down costs,” said Paul Winnowski, CEO of Mainstream Energy Corp. “Combining our capabilities deepens our relationship and strengthens our shared vision for greater adoption of home solar by more families across the country.”
