Tandem PV has opened a commercial demonstration factory in Fremont, California, marking a step toward industrial-scale production of perovskite-silicon solar panels for utility-scale renewable energy deployment.

Business Wire reported that the facility is designed to transition the company’s photovoltaic technology from laboratory development into repeatable manufacturing, supporting broader efforts to scale next-generation solar production in the United States.

The 65,000-square-foot facility has an annual nameplate capacity of approximately 40 MW and is producing large-format tandem solar modules intended for customer validation and early market trials.

The company stated that the plant supports efforts to strengthen domestic solar manufacturing supply chains as electricity demand increases, driven by data centre expansion and artificial intelligence workloads.

Scott Wharton, chief executive officer of Tandem PV, said: “This factory marks the shift from impressive R&D results to repeatable manufacturing at a commercially meaningful scale. People have talked for years about the promise of perovskites. This is what it looks like to deliver. It is an important milestone in restoring American leadership in solar manufacturing through the kind of breakthrough engineering Silicon Valley is known for.”

Tandem PV’s technology combines a perovskite light-absorbing layer with conventional silicon cells to increase energy conversion efficiency and improve power output per module footprint.

The company reports internal testing efficiency levels of 29.7 per cent and reduced annual power degradation through accelerated performance testing, targeting long-term durability aligned with utility-scale requirements.

Jennifer Granholm, former US energy secretary, said: “Utility-scale perovskites are here. Tandem PV is delivering an ingenious product that can help provide more clean power with a smaller footprint and meaningful cost savings as we scale deployment in the United States.”
