TOYO to invest $357 million in 1.5 GW heterojunction solar cell manufacturing facility in Houston, Texas

Type: Investment · Technology: Solar · Country: United States · Capacity: 1.5 GW · Value: $357M · Announced: 2026-06-08

Japanese solar manufacturer TOYO announced a $357 million investment to construct a 1.5 GW heterojunction (HJT) solar cell manufacturing facility in the Houston metropolitan area, Texas. The project will co-locate cell production with TOYO's existing 2 GW module assembly plant in Texas to qualify for U.S. Section 45X production tax credits, which provide $0.04 per watt for domestically produced solar cells. At full capacity, the facility could generate up to $60 million annually in 45X credits, while enabling developers to access an additional 10% domestic content bonus under the Investment Tax Credit (ITC) and Production Tax Credit (PTC) frameworks. Engineering, facility design, and procurement planning are already underway, with pilot production expected within 20 months of the announcement. The Houston site leverages existing infrastructure, local permitting processes, and a skilled workforce to mitigate development risks and accelerate deployment.
