Qcells to expand U.S. module manufacturing capacity with new 1.4-GW factory

The largest crystalline silicon module manufacturer in the United States is going to get even bigger. Hanwha Solutions, the company behind Qcells, announced it will invest $170 million in a new US solar module assembly plant that will have a manufacturing capacity of 1.4 GW. Qcells already operates a 1.7-GW module plant in Georgia.

The new factory, which the company has yet to disclose its location, should come online as early as the first half of 2023. This will bring Qcells’ total US module capacity to 3.1 GW.

Hanwha will also increase its cell production capacity in South Korea by investing $150 million to expand its existing factory. When the expansion plan is complete, overall cell capacity in South Korea will total 5.4 GW. To further improve and decarbonize its solar panel production process, Hanwha will secure low-carbon polysilicon from manufacturers around the world. The company has relationships with Korean polysilicon manufacturer OCI and Norway-headquartered and Washington-based REC Silicon.

“Growing uncertainties tell us that securing reliable, sustainable energy has become more important than ever before,” said Justin Lee, CEO of Hanwha Qcells. “To do this, Qcells will increase renewable supply from diversified sources and find cleaner ways to produce energy. That way, we will contribute to both energy security and net-zero emissions.”


After these two expansions of module and cell manufacturing capacity, Hanwha plans to further invest in the US solar supply chain, including wafers and cells.

“Ensuring policy certainty is crucial to realizing our goal of rebuilding the US solar value chain,” said Lee. “With our relentless efforts to provide reliable, sustainable energy, we will do our utmost to solidify Qcells as the dependable choice for the US solar market.”
