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.”

A research lab at the University of Houston has developed a new type of material for sodium-ion batteries that could make them more efficient and boost their energy performance.

Led by Pieremanuele Canepa, Robert Welch assistant professor of electrical and computer engineering at UH, the Canepa Research Laboratory is working on a new material called sodium vanadium phosphate, which improves sodium-ion battery performance by increasing the energy density. Energy density is the amount of energy stored per kilogram, and the new material can do so by more than 15 percent. With a higher energy density of 458 watt-hours per kilogram — compared to the 396 watt-hours per kilogram in older sodium-ion batteries — this material brings sodium technology closer to competing with lithium-ion batteries, according to the researchers.

The Canepa Lab used theoretical expertise and computational methods to discover new materials and molecules to help advance clean energy technologies. The team at UH worked with the research groups headed by French researchers Christian Masquelier and Laurence Croguennec from the Laboratoire de Reáctivité et de Chimie des Solides, which is a CNRS laboratory part of the Université de Picardie Jules Verne, in Amiens France, and the Institut de Chimie de la Matière Condensée de Bordeaux, Université de Bordeaux, Bordeaux, France for the experimental work on the project.

The researchers then created a battery prototype using the new materia sodium vanadium phosphate, which demonstrated energy storage improvements. The material is part of a group called “Na superionic conductors” or NaSICONs, which is made to let sodium ions move in and out of the battery during charging and discharging.

“The continuous voltage change is a key feature,” Canepa says in a news release. “It means the battery can perform more efficiently without compromising the electrode stability. That’s a game-changer for sodium-ion technology.”

The synthesis method used to create sodium vanadium phosphate may be applied to other materials with similar chemistries, which could create new opportunities for advanced energy storage. A paper of this work was published in the journal Nature Materials.

"Our goal is to find clean, sustainable solutions for energy storage," Canepa adds. "This material shows that sodium-ion batteries can meet the high-energy demands of modern technology while being cost-effective and environmentally friendly."
