Vietnam-based solar cell and module manufacturer, Boviet Solar Technology, has added a third module manufacturing production line at its facility in Greenville, North Carolina, in the U.S., expanding its production capacity from 2 GW to 3 GW.

The company added the third manufacturing line to enhance its ability to meet the U.S.’s growing demand for domestically produced solar products.

The Greenville manufacturing facility’s first phase commenced operations in April this year. It produces Boviet Solar’s Gamma series monofacial and Vega series bifacial solar modules. The company had announced its investment of $249 million for the facility in April last year.

In August, Boviet Solar completed the exterior construction of its Greenville facility’s second phase, which is expected to begin mass production in 2026.

“The Greenville manufacturing hub is central to Boviet Solar’s U.S. growth strategy,” said Sienna Cen, President at Boviet Solar USA. “By investing in both photovoltaic cell and module production in North Carolina, we are strengthening supply chain resilience, delivering reliable ‘Made-in-USA’ solar products, and creating lasting economic impact for the region.

The company said the Greenville facilities represent over $400 million in total capital.

Founded in 2013 in Vietnam, Boviet Solar is a subsidiary company of Boway Alloy. The company specializes in mono PERC, TOPCon cells, and various monofacial and bifacial module series. It has offices in the U.S., Germany, and China.

The U.S. added 8.6 GW of solar module manufacturing capacity in the first quarter of 2025, bringing the total to 51 GW. Further expansions could raise capacity to 88 GW by year-end, though many announced projects are not yet under construction.

In April this year, the U.S. Department of Commerce announced its final determinations in the anti-dumping and countervailing duty investigations concerning crystalline silicon photovoltaic cells and modules imported from Cambodia, Malaysia, Thailand, and Vietnam.

These findings confirmed that exporters from the four nations sold solar cells in the U.S. at less than fair value and that producers in these countries benefited from subsidies, some of which originated from a third country—China.
