A California man who took part in a billion-dollar Ponzi scheme through a fake solar power supply company has been sentenced to six years in prison and ordered to pay $624 million in restitution, the Department of Justice (DOJ) has announced.
Robert A. Karmann, 55, a certified public accountant, was hired by DC Solar, a company based in Benicia in the San Francisco Bay Area that manufactured mobile solar generator (MSG) units—solar panels mounted on trailers—as its controller in 2014. He later became the company’s chief financial officer.
