About T1 Energy

At T1 Energy (NYSE: TE), we build energy. We are an American solar manufacturer building the future of energy abundance. From our headquarters in Austin, Texas, we’re pioneering a domestic solar supply chain with one mission: to invigorate America with scalable, reliable, and low-cost energy.

We started with G1_Dallas, one of the most advanced solar manufacturing facilities in the world. The 5GW facility is located in Wilmer, Texas. It has the capacity to produce more than 20,000 solar modules a day for solar farms that power American homes, businesses, and keep our energy grids resilient.

Next is G2_Austin: Our new solar cell fab in Rockdale, Texas. Its first 2.1GW phase is designed to produce next-generation TOPCon cells beginning in 2027. As the fab grows, it’s expected to support up to 1,800 manufacturing jobs. Modules assembled at G1 can run on cells from G2.

What comes after G2? Come join us and help figure that out. And then build it. The sun has always shone on America. Now you can turn it into abundant electricity.
