Seoul-based photovoltaics (PV) manufacturer Qcells, part of South Korean conglomerate Hanwha Group, has launched cell production at its factory in Cartersville, Georgia.

The company’s Cartersville, Georgia, factory is the largest of its kind in the nation — and it just started producing the key solar panel component.

The Cartersville plant is a milestone for domestic clean energy as developers rush to beat upcoming tax deadlines.
