Home / Solar Power / 20GW of new silicon manufacturing capacity – LONGi vs GCL Poly arms race

20GW of silicon manufacturing is not trivial. Global volume installed last year was ~98GW. Adding 20% of capacity is big. What’s really interesting is that GCL-Poly and LONGi are ramping up some serious competition! And that is really exciting – because two companies with ego fighting each other helps us all.

SOURCE: The factory will be established in two phases, each installing annual production capacity of 10GWp, using CCZ (continuous-fed Czochralski) crystal-growing technology. GCL-Poly obtained CCZ technology from SunEdison whose PV assets it acquired in 2016. LONGi Green Energy Technology, the largest China-based solar mono-Si wafer maker, plans to expand production capacity from 15GWp at year-end 2017 to 28GWp at year-end 2018, 36GWp at year-end 2019 and 45GWp at year-end 2020.
