Clemens Hofbauer, Vice President of Manufacturing, Tandem PV

Clemens joins Tandem PV with more than 25 years of experience in global solar and battery manufacturing. He previously served as General Manager of SunPower’s solar module facility in Hillsboro, Oregon, and held senior leadership roles at SolarWorld, Silicor Materials, and Sila Nanotechnologies. His background includes overseeing operations in the U.S., Germany, Sweden, and Canada, and leading the development of a $1 billion solar silicon plant in Iceland.

Tandem PV is currently building out the manufacturing infrastructure needed to accelerate product commercialization and meet growing demand. The company’s proprietary solar panels combine thin-film perovskite with conventional silicon, generating up to 30% more power than standard panels. By establishing large-scale U.S. production, the company will lower costs, shorten lead times, and help reestablish American leadership in clean energy manufacturing.

“Clemens brings a highly distinctive background that spans U.S. manufacturing, silicon solar production, and thin-film solar — a rare combination that makes him exceptionally well-suited to lead our manufacturing efforts,” said Scott Wharton, CEO of Tandem PV.

“I’m thrilled to join Tandem PV at such a pivotal moment, not just for the company, but for the future of American solar manufacturing,” said Clemens Hofbauer. “Building out domestic production for this next-generation solar technology is an exciting opportunity to help strengthen U.S. leadership in clean energy.”

Tandem PV was recently named to TIME Magazine’s list of the Top GreenTech Companies of 2025 and included in Congruent Ventures’ “50 by 2050” list of top climate tech startups.
