Vietnamese solar manufacturer Boviet Solar has added an additional 1GW of manufacturing capacity to its module manufacturing plant in North Carolina, bringing its total annual capacity to 3GW.
The company started work at the Greenville PV Module Factory in April of this year, which produces its Gamma series of monofacial modules and its Vega series of bifacial modules, both of which use passivated emitter rear contact (PERC) technology. The factory now boasts three module production lines, which the company says will “meet the growing demand for domestically produced solar products”.

“The addition of a third production line marks another important milestone in our Greenville journey,” said general manager of the Greenville factory Marco Marquez. “It further enhances our ability to serve our customers with reliable, US-made PV modules while creating high-quality local jobs.”
Demand for US-made solar products has increased considerably this year, particularly following the passage of the ‘One Big, Beautiful Bill’ over the summer. While this has translated to the deployment of more module manufacturing capacity, with the US adding 8.7GW of new capacity in the first nine months of the year, cell manufacturing capacity has grown less quickly, with just 2GW of new capacity added in 2024 and 2025.
Boviet Solar has sought to expand cell manufacturing capacity in tandem with its module manufacturing capacity, and in August completed exterior construction work on a cell manufacturing facility at the Greenville site. The cell facility is expected to begin commercial operation in the second half of 2026, and the factory’s cell and module components represent a US$400 million investment.
Alongside Boviet Solar, ES Foundry has advanced its own cell manufacturing facility in the US, starting work at its plant in February, just across the border in South Carolina. ES Foundry is also focusing on PERC cells, and earlier this month, CEO Alex Zhu told PV Tech Premium that the technology is more “proven and reliable” than tunnel oxide passivated contact (TOPCon), the cells of which are more efficient, but have been subject to a number of patent disputes between manufacturers so far this year.

PV Tech has been running an annual PV CellTech Conference since 2016. PV CellTech USA, on 7-8 October 2025 is our third PV CellTech conference dedicated to the U.S. manufacturing sector. The events in 2023 and 2024 were a sell out success and 2025 will once again gather the key stakeholders from PV manufacturing, equipment/materials, policy-making and strategy, capital equipment investment and all interested downstream channels and third-party entities. The goal is simple: to map out PV manufacturing in the U.S. out to 2030 and beyond.
Returning for its 12th edition, Solar and Storage Finance USA Summit remains the annual event where decision-makers at the forefront of solar and storage projects across the United States and capital converge. Featuring the most active solar and storage transactors, join us for a packed two-days of deal-making, learning and networking.
PV Tech has been running PV ModuleTech Conferences since 2017. PV ModuleTech USA, on 16-17 June 2026, will be our fifth PV ModulelTech conference dedicated to the U.S. utility scale solar sector. The event will gather the key stakeholders from solar developers, solar asset owners and investors, PV manufacturing, policy-making and and all interested downstream channels and third-party entities. The goal is simple: to map out the PV module supply channels to the U.S. out to 2027 and beyond.
