Mainstream Energy Sells Residential Solar Business To Sunrun


Mainstream Energy has separated its REC Solar commercial and residential operations, selling the latter to Sunrun. Continuing under the name REC Solar Commercial Corp., the company will focus solely on designing and building solar projects for businesses, municipalities, utilities and other customers of commercial-scale photovoltaic systems.

Mainstream Energy has also sold its AEE Solar distribution and SnapNrack solar mounting systems businesses to Sunrun. Paul Winnowski, CEO of Mainstream Solar, joins Sunrun as chief operating officer. Timothy Ball, chairman of Mainstream Energy, will join Sunrun's board of directors.

On the Sunrun side, Lynn Jurich will lead the company as CEO, while co-founder Ed Fenster will continue in his operating role under the new title of chairman. Tom Holland assumes the role of president.

REC Solar has recruited Paul Detering as its new CEO. Prior to joining REC Solar, Detering was CEO of developer Tioga Energy.

‘The commercial and residential solar businesses are built upon fundamentally different models, with unique customer bases and disparate sources of capital,’ Detering says. ‘With this decision, REC Solar can better serve the needs of our commercial solar customers moving forward.’
