SEG Solar is doubling down on US manufacturing with plans for a third solar module factory in the Houston, Texas, area.
The Houston-based company announced on Monday that it’s building a new 4.6-gigawatt (GW) solar module manufacturing facility in Greater Houston. Once it’s online, SEG says its planned US module manufacturing capacity will hit 10.6 GW annually.
That would make SEG one of the larger domestic solar module manufacturers at a time when US solar companies are racing to localize supply chains amid shifting tariffs and trade rules.
SEG has already signed an agreement with a local construction company to develop the new facility, which will span around 1.15 million square feet and include both a factory and warehouse.
The announcement comes just ahead of the grand opening of SEG’s second US factory, a 4 GW facility that’s scheduled to officially open on August 7, 2026.
