SEG Solar has inaugurated its second U.S. photovoltaic module plant in Texas, raising its domestic production capacity to 6 gigawatts a year, backed by a 200 million dollar investment.
SEG Solar inaugurated its second photovoltaic module manufacturing plant in the United States on August 7, 2026, named Tomball #1, in the Greater Houston area of Texas. The opening raises the company’s total U.S. module production capacity to 6 gigawatts (GW) per year, according to SEG Solar. The U.S. solar sector continues to expand at a steady pace, as illustrated by the 155 MW solar deal signed between RWE and Google in Oklahoma. The inauguration gathered approximately 800 attendees, including employees, local officials, industry partners and media representatives.
The site represents an investment of 200 million dollars ($200 million) and spans more than 500,000 square feet, according to the company. SEG Solar states that it is its largest module manufacturing facility in the United States and one of the largest heterojunction (HJT) module manufacturing facilities in the country. This investment momentum in solar is not confined to the United States, as shown by Sonnedix, which raised €730 million to finance its solar assets across Southern Europe.
The facility has an annual production capacity of 4 GW, spread across four lines dedicated to manufacturing high-efficiency SIERRA N series modules, according to SEG Solar. These lines support both 210 mm and 210R wafer formats. The company states that the site incorporates HJT-specific manufacturing processes, including low-temperature soldering and precise butyl sealant application, intended to enhance module reliability and durability.
Jun Zhuge, Founder and Chief Operating Officer (COO) of SEG Solar, said commercial operations at Tomball #1 are expected to begin in the third quarter of 2026. He added that the company is currently developing a third U.S. HJT module manufacturing facility and planning the construction of a U.S. cell manufacturing plant. According to him, these investments aim to strengthen the domestic supply chain and position SEG Solar as the largest crystalline solar module manufacturer in the United States.
The inauguration brought together several local officials, including Bobby Lieb, President and CEO of the Northwest Houston Chamber of Commerce, and Ed Gonzalez, Sheriff of Harris County. Guest speakers also included Natasha Cherenkova, Senior Vice President of DEPCOM Power, and Paul Wormser, Senior Vice President of Technology at Intertek. Their remarks highlighted SEG Solar’s contribution to advancing U.S. solar manufacturing and its continued investment in the Tomball community.
Italy's FER X ministerial decree, effective August 7, 2026, sets a 37.15 GW cap for solar, wind, hydropower and biogas capacity, introducing new component-origin requirements.
