HOUSTON, June 1, 2026 /PRNewswire/ — SEG Solar ("SEG"), a leading U.S. solar module
manufacturer, today announced plans to develop its third U.S. manufacturing facility
in Greater Houston, Texas. The new 4.6-gigawatt (GW) facility is expected to bring
SEG’s planned annual U.S. module manufacturing capacity to 10.6 GW, further strengthening
the company’s position as one of the largest domestic solar module manufacturers
and advancing its long-term localization strategy.

As part of its continued U.S. expansion, SEG has signed an agreement with a local
construction company to develop the new 4.6 GW facility on a site spanning approximately
1.15 million square feet, including a factory and a warehouse. The announcement 
comes ahead of the grand opening of SEG’s second 4 GW factory, scheduled for August
7, 2026. Construction of the third facility is projected to be completed by March
2027, with commercial production expected to begin in May 2027.

The new facility is being planned to support SEG’s transition toward next-generation
HJT technology, enabling high-efficiency module production aligned with the evolving
needs of the U.S. market. The facility is also designed to support FEOC-compliant
module production through strengthened supply chain traceability, material control,
and compliance management.

To further support its U.S. manufacturing expansion and strengthen resilience amid
evolving trade and supply chain policies, SEG has initiated planning for an ingot
and wafer facility in Indonesia. This upstream integration is intended to secure
critical components and enhance the resilience of SEG’s global supply chain. SEG
is also evaluating potential U.S. sites for a dedicated HJT cell manufacturing facility,
further advancing its strategy to localize key manufacturing processes and strengthen
control over next-generation solar technologies.

With expanded U.S. module capacity, upstream supply chain integration, and a planned
transition toward HJT technology, SEG continues to support the U.S. energy transition
with reliable, compliant, and high-efficiency solar solutions.
