In August 2012, the Hanwha Group, a large South Korean business conglomerate, agreed to acquire Qcells, saying that it presented synergy opportunities.

[18] In January 2023, Qcells made a commitment to invest more than $2.5 billion to build a fully integrated, silicon-based solar supply chain in the United States from raw material to finished module with full production expected by the end of 2024.

[19] In August 2024, Qcells received a conditional commitment for a future $1.45 billion loan from the US department of energy to help finance the construction of a fully integrated solar cell manufuacturing facility north of Atlanta, Georgia.

The loan guarantee was approved in part by Qcells receiving an order from Microsoft for 12 gigawatts of solar panels through 2032 thus demonstrating a market for their product.

[22] Qcells also operates a residential solar financing platform in the United States, EnFin, offering loans for those who choose to install PV systems in their homes.

In August 2023, the U.S. Department of Commerce ruled that Qcells had not circumvented tariffs on Chinese-made goods following an investigation involving multiple photovoltaic cell manufacturers.

[23][24] In July 2024, it was reported that Hanwha Qcells' factory in Dalton, Georgia, was importing cells made with Chinese wafers from TCL Zhonghuan Renewable Energy Technology Co. and Gokin Solar Co., wafer suppliers who source Xinjiang, China polysilicon from Daqo and GCL, both of which are on the UFLPA Entity List.

The Commerce Department calculated a subsidy rate of 14.72% for Hanwha Qcells products produced in Malaysia, based in part on government loans and below-market land provisions to the company in that country.

It produces and installs PV systems for commercial, industrial, and residential applications and provides EPC services for large-scale solar power plants.
