A Houston-based photovoltaic manufacturer has celebrated the opening of its new manufacturing base in Houston.

SEG Solar's new facility spans 250,000 square feet and will house production workshops, raw material warehouses, administrative offices, finished goods warehouses, and supporting infrastructure. It features two intelligent manufacturing lines that will produce the latest N-type high-efficiency PV modules, which is expected to have production capacity exceeding 2 gigawatts annually. The project cost $60 million.

“The Houston plant is a key part of SEG’s strategy to serve the U.S. market,” Jim Wood, CEO of SEG, says in a news release. “With new workshops, production lines, and equipment, SEG will offer a refreshed experience to the U.S. market.”

In addition to the ribbon cutting for the new facility, SEG Solar rolled out its first 585-watt YUKON N series module during the opening on August 9, which helps establish SEG as one of the first manufacturers to achieve module production in the United States.

The production lines will be compatible with 182mm and 210mm N-type cells and will be fully equipped with automated intelligent manufacturing systems, which can ensure seamless integration of automation, information and intelligence. The technological collaboration assists with manufacturing efficiency. The workshop will feature advanced ERP and MES systems for refined management and traceability of incoming materials.

SEG has shipped over 5 gigawatts of solar modules worldwide. The company says it expects to exceed a production capacity of 5.5 gigawatts by the end of 2024. According to SEG, customers will benefit from faster delivery times and enhanced after-sales service after the opening of the Houston plant. Houston’s key location will help reduce transportation costs, according to the company. Expanding out of Houston and the U.S. market, SEG plans to establish Southeast Asia's largest photovoltaic industrial park in Indonesia in 2025.

SEG hopes to establish its global R&D center at the Houston PV manufacturing base before the end of 2024 that will offer testing services, like LID tests, Damp Heat tests, PID tests, and Light and LeTID tests.

“As a leading U.S. solar company, SEG is proud to be among the first to respond to the call for domestic manufacturing by constructing a solar module factory in the U.S.,” Wood says in his keynote speech at the opening ceremony. “The completion of the Houston plant marks a significant milestone for SEG and a major advancement in U.S. module manufacturing technology.

"Looking ahead, SEG will continue to deepen its investments in wafers, cells, and modules, closely tracking market trends to meet our customers' needs," he continues. "Through strategic collaborations across the supply chain, we aim to continuously optimize and enhance the U.S. PV manufacturing industry.”

Houston-based Flathead Forge Fund 1 has invested in Houston startup Solidec, which specializes in modular onsite chemical manufacturing.

The investment was part of Solidec’s recent round of more than $2 million in pre-seed funding. The amount of Flathead Forge’s investment wasn’t disclosed.

“Flathead Forge brings exactly the kind of domain-specific capital and operational network that a company at our stage needs. Their focus on water and critical minerals makes this a genuinely strategic relationship,” Ryan DuChanois, co-founder and CEO of Solidec, said in a news release.

Other investors in the round included New Climate Ventures, Collaborative Fund, Echo River Capital, Ecosphere Ventures, Plug and Play Ventures, Safar Partners and Semilla Climate Capital.

Solidec produces industrial chemicals, including hydrogen peroxide, formic acid and acetic acid, using only air, water and electricity. Its modular reactors eliminate the need for energy-intensive production and long-haul distribution.

“Solidec’s platform cuts cost, emissions, and supply-chain fragility at the source,” Douglas Lee, managing director of Flathead Forge, added in the statement.

DuChanois said in an email that the company plans to use the funding to "scale (its) modular chemical manufacturing platform."

Solidec recently announced a pilot project with Lynas Rare Earths, the world’s only commercial producer of separated light and heavy rare earth oxides outside China, for production of hydrogen peroxide for a Lynas facility in Australia.

Solidec, a member of Greentown Labs Houston, spun out of associate professor Haotian Wang’s lab at Rice University in 2024. Wang focuses on developing new materials and technology for energy and environmental uses, such as energy storage and green synthesis.
