Hanwha Solutions has begun full-scale commercial production of solar cells at its Cartersville plant in Georgia, USA. This transforms the company's local business structure from its previous focus on module assembly to an integrated production system that manufactures core components in-house. As the U.S. continues to face a solar cell supply shortage, attention is focused on whether the Cartersville plant will emerge as a new growth hub for Hanwha Solutions' North American business.

According to the U.S. energy media outlet Canary Media, Hanwha Solutions' Qcells division commenced commercial production of silicon solar cells at its Cartersville plant in Georgia in June. Canary Media described the facility as the largest operating solar cell production plant in the United States.

Solar cells are core components that convert sunlight into electricity, and multiple cells are connected to manufacture solar modules. While module production facilities have rapidly expanded in the U.S. recently, cell production infrastructure remains relatively insufficient, leaving the country heavily dependent on overseas procurement.

According to Reuters, U.S. solar module production capacity reaches approximately 60 gigawatts (GW) annually, but cell production capacity stands at only 3.2 GW. If the Cartersville plant secures an annual cell production capacity of 3.3 GW, total U.S. cell production capacity would more than double on a simple aggregate basis.

Establishing a Vertically Integrated Production System

Qcells expects that once the Cartersville plant is fully operational, it will be able to produce ingots, wafers, and cells at 3.3 GW each annually. Solar module production capacity is planned at 3.5 GW per year. Ingots are materials made by processing polysilicon for solar use into cylindrical forms, and wafers — thin slices cut from ingots — are processed to make cells.

Historically, U.S. solar manufacturing typically involved procuring cells or wafers externally and assembling modules at local plants. Qcells explained that the Cartersville plant is the first and only vertically integrated solar facility in the United States, producing ingots, wafers, cells, and finished modules in one location. According to the company, the plan is to build a production system that connects core components through to finished products locally.

The Cartersville plant is also linked to the existing Dalton plant in Georgia. Qcells announced plans to combine the solar module production capacity of both facilities to reach 8.6 GW annually by the end of the third quarter of 2026. This scale is equivalent to the solar capacity needed to supply electricity to approximately 1.3 million U.S. households for one year.

Expectations for Tax Benefits and Profitability Improvement

The operation of the Cartersville plant is expected to impact not only production volume but also the profitability structure of Hanwha Solutions' U.S. business. Wafers, cells, and modules produced in the U.S. may qualify for the Advanced Manufacturing Production Credit, which is linked to domestic production volumes. Additionally, solar power operators using U.S.-made components may be better positioned to receive additional tax credits if they meet relevant conditions.

If Qcells supplies both cells and modules, it will also help customers meet local procurement ratio requirements. As plant production volume and utilization rates increase, the company is likely to benefit not only from product sales but also from expanded tax effects associated with local production. However, the actual scale of tax credits may vary depending on production items, volumes, application periods, and detailed requirements.

Key Points to Watch

The module production line at the Cartersville plant is already in operation. Qcells has set a goal of sequentially expanding ingot, wafer, and cell production equipment to reach planned capacity by the third quarter of 2026.

The market is expected to view the Cartersville plant's cell production volume, yield, and utilization rate as key indicators for Hanwha Solutions' North American business going forward. Cell manufacturing involves more complex processes than module assembly, meaning that stabilizing yield rates and managing costs during initial production will directly impact profitability.

Once cell production stabilizes, Hanwha Solutions can expand its position as a supplier of both core solar components and finished products in the United States. The ability to reduce reliance on external cell procurement and directly manage production schedules and inventory is also cited as a factor that will enhance business stability.

Hanwha Solutions' U.S. solar business has entered a phase of expanding its production scope beyond module manufacturing to include ingots, wafers, and cells. How quickly the Cartersville plant reaches its planned capacity and translates that into actual profitability improvements is expected to be a key factor to watch for the North American business going forward.
