Alex Zhu discusses the importance of solar cell manufacturing in the U.S. and the strategic decisions behind building a factory.

Rebuilding solar manufacturing in the U.S. is not just about capital or policy. It is about making the right bets at the right time. It comes down to timing, experience, and the critical decisions. Alex Zhu has spent nearly two decades inside the global solar manufacturing system—from the early rise of Chinese production to failed U.S. factory attempts, and now to building one of the few solar cell manufacturing facilities in America through ES Foundry. In this conversation, Alex explains why he focused on solar cells instead of modules . Module assembly scaled quickly after the IRA. Cell manufacturing remained limited, even though it sits at the center of the supply chain. But that gap is precisely where Alex recognized his greatest strength. Experience. But the ensuing decisions (bets) he made carry real risk. He is betting that the U.S. cannot sustain a domestic solar industry without cell production. He is also building on proven PERC technology , even as the global market moves toward TOPCon. And he is relying on speed, execution, and hard-won experience to make that strategy work. We also get into how his past shaped these decisions, what has changed since earlier U.S…
