Wrong! From their 2016 SEC 10-K report (Google to find it, link is too long) page 14:
Polysilicon is melted and grown into crystalline ingots and sawed into wafers by business partners specializing in those processes. The wafers are processed into solar cells in our manufacturing facility located in the Philippines and by our jointventure, AUOSP, located in Malaysia. The solar cell manufacturing facility we own and operate in the Philippines has a total rated annual capacity of over 700 MW. AUOSP currently operates a solar cell manufacturing facility with a total rated annual capacity of over 800 MW. We also own a 215,000 square foot building in the Philippines that will serve as an additional solar cell manufacturing facility with a planned annual capacity of 350 MW once fully operational, which is expected to occur in fiscal 2015.
Using our solar cells, we manufacture our solar panels at our solar panel assembly facilities located in the Philippines, Mexico and France. Our solar panel manufacturing facilities have a combined total rated annual capacity of over 1.1 GW. Our solar panels are also assembled for us by third-party contract manufacturers in California and China.
Yep made in the USA, enjoy the coffee sport.
