GEORGETOWN, TX—GAF Energy is investing $100 million to build a new assembly plant here to make solar roof shingles for residential housing domestically rather than in Asia.

The announcement comes amid growing concerns about the country’s overreliance on Chinese-made solar products. In the past two years, U.S. panel supplies have faced major disruptions due to pandemic-related supply chain turmoil, import tariff threats and increased border scrutiny.

The new assembly plant will increase GAF Energy’s domestic production capacity to 300 megawatts annually, up from 50 megawatts today. The company already operates an assembly plant in San Jose, CA, where it is headquartered.
