I guess the question is, where might the T1 Chinese be on efficiency and costs in five, ten years?
I think explo touched on this. Many, who see FSLR sparkle on efficiency, consider Chinese to be sitting on their hands and get surprised. While mass produced modules have added half a percent or up to a percent in last 3 years for FSLR and thin-film, Chinese went from 14.5 to 16.3% modules mass produced and in fact becoming major volume in shipments.
If I was going to benchmark Cad at poly and without FSLR moving into poly, I see Chinese 10 years ahead FSLR from today, meaning keeping the distance.
Those guys will be the solar industry with couple foreign companies left. They will be the innovation, swallowing new solutions and designs and putting them out on field in short order.
