Just speculating because they are in Arizona.
In October 2010, Suntech opened the doors on our state-of-the-art, 117,000 square foot manufacturing facility in Goodyear, Arizona. Since then, we’ve grown steadily and are now operating 24 production hours per day with an annualized throughput of 50MW, after adding a third production shift in May 2011. Suntech now proudly employs more than 100 well-trained manufacturing professionals in Arizona who are producing about 15,000 high-quality 275W and 280W solar panels per month, with further growth planned.
