Residential solar financing platform Mosaic has announced that Robert D. Kelly will serve as a member of the company’s Board of Directors.

Kelly — who recently retired from his post as chief financial officer at SolarCity — will join Tom Dinwoodie and Lisa Gansky on the Mosaic board.

Billy Parish, CEO of Mosaic, said: "Bob has unparalleled solar finance experience, including bringing SolarCity public and achieving the solar industry's first securitization. His accomplishments have accelerated the growth and adoption of solar nationwide."

Kelly added: "I'm thrilled to be joining Mosaic's board of directors; the company is a leader in the residential solar finance space, offering the best loan products and a proven technology platform. I look forward working with Mosaic to help guide their successful expansion.”

During his time at SolarCity, Kelly helped lead the company through its initial public offering in 2012. Before serving at SolarCity, Kelly was the chief financial officer at Calera — a clean technology company aimed at reducing CO2 emissions by converting it into useful materials.

Prior to his tenure at Calera, Kelly was chief financial officer and executive vice president at Calpine, overseeing the company’s IPO. Under Kelly’s watch, Calpine’s electricity generation capacity grew from 1MW to 25,000MW.
