Sopogy, an Hawaii-based concentrating solar thermal technology company, has raised its Series E financing.
The amount was not disclosed.
The round, which included preferred stock and warrants, was led by Mitsui & Co., with participation from Southern California Gas Company, 3M, Kolohala Ventures and Enerdigm Ventures.
Led by Darren T. Kimura, President and CEO, Sopogy has pioneered the concept of MicroCSP. It develops modular collectors about one-third the size of a traditional concentrated solar power mirror, to create high quality thermal heat to be used in the industrial process and as solar steam.
