Powering Solar's Next Chapter

John Beaver, CFO of Highland Materials, brings a unique perspective to solar manufacturing after living through two distinct cleantech eras. Following 25 years in the chemical industry, Beaver first entered solar in 2009 as CFO of Silicor Materials, scaling from 40 to 450 employees in 18 months while proving metallurgical-grade silicon could produce high-quality solar cells. "We ended up making 20 million solar cells. Really proved out the concept that we could use a metallurgical grade silicon versus electronic grade silicon to make high-quality solar cells," Beaver explains. After weathering policy headwinds and Chinese oversupply that shuttered their plans, Beaver spent years in dental lasers before returning to solar silicon at Highland Materials. Now he believes the tipping point has arrived. The big question: Can domestic manufacturing finally compete with China's 95% market control? John Beaver serves as Chief Financial Officer of Highland Materials, and has over 40 years of finance expertise across a variety of industries. After starting his career at Fortune 50 company Monsanto, Beaver spent decades in the chemical industry before making his first foray into cleantech as the inaugural CFO of Silicor Materials in 2009. There, he helped scale the company from 40 to 450 employees in 18 months while proving that metallurgical-grade silicon could produce solar cells indistinguishable from traditional electronic-grade silicon. Following a detour as CEO of dental laser company Biolase, Beaver returned to solar silicon manufacturing with Highland Materials, where he's working to establish domestic polysilicon production in Tennessee using zero-waste technology that cuts emissions by 90% while recycling industry waste into valuable raw materials.
