IEA: The world will almost completely rely on China for the supply of key building
blocks for solar panel production through 2025.
Based on manufacturing capacity under construction, China’s share of global polysilicon, ingot and wafer production will soon reach almost 95%.
Today, China’s Xinjiang province accounts for 40% global polysilicon manufacturing. Moreover, one out of every seven panels produced worldwide is manufactured by a single facility.
This level of concentration in any global supply chain would represent a considerable vulnerability; solar PV is no exception.
