David Kaltsas

Chief Operating Officer

David is all about making solar happen. For him, the union of solar and roofing is the best way to increase solar adoption that he’s seen in his 20 years of working in energy infrastructure. He has an extensive background in solar with specific expertise in the commercial and industrial space, serving as COO of Sol-Wind and President and COO of SunWize. He holds a BA in Global Change and Transformational Leadership from the University of St. Thomas. His favorite roof is on the headquarters of Mitsui & Co in Tokyo, which has solar on top and a courtside view of the Imperial Palace.
