Hanwha Q Cells officially opened its 300,000 square foot solar panel factory in Dalton, Georgia last week, claiming it is the largest such manufacturing facility in the western hemisphere. The $200 million factory employs more than 650 workers and is capable of producing 12,000 solar panels a year — enough to generate 1.7 GW of electricity. Its standard production panel features six bus bars, has an efficiency of about 19%, and an output of up to 345 watts.
