Some of this is related to China's apparent mastery of monocrystalline silicon PV technology. The article and the graph don't distinguish panels by mono vs poly but for non-thin-tech panels, monocrystalline is preferable. See (2018): https://www.pv-magazine.com/2018/04/14/the-weekend-read-chinas-monocrystalline-boom/ https://www.pv-magazine.com/2018/04/14/the-weekend-read-chin... > "When potential expansions from other mono ingot and wafer makers are factored in, this points to a tectonic shift in the supply of monocrystalline silicon which threatens to reconfigure the entire upstream solar landscape and potentially push monocrystalline silicon solar into a dominant market position in much shorter timeframe than previously anticipated."
