Recently, the International Energy Agency (IEA) "Advancing Clean Technology Manufacturing" report shows that, at present, the global solar cell and module manufacturing utilization rate of about 50%, only in 2023, the global investment in new solar factories amounted to 80 billion U.S. dollars, is two times in 2022.
Last year, China's solar industry accounted for about 951 TP3T of global investment in silicon wafer capacity, 961 TP3T in polysilicon production facilities, and 831 TP3T in module factories.The IEA said about 440 GW of the 500 GW of total cell and module capacity was deployed globally last year.
Existing manufacturing capacity for PV modules and cells could today achieve the capacity needed to meet demand under New Zealand's economic scenario in 2030, six years ahead of schedule, with only modest gaps remaining in the upstream steps of wafer and polysilicon manufacturing," the report states. "While the sharp increase in supply has depressed module prices and supported wider consumer acceptance, inventories of solar PV modules are growing and there are signs that planned capacity expansions are being scaled back and delayed, particularly in China."
The agency said that about 80% of the world's PV manufacturing is now concentrated in China, with India and the US each accounting for 5%, and Europe accounting for only 1%.
The high level of geographic concentration in the PV supply chain is unlikely to change significantly, with China's share of module, cell and wafer capacity declining slightly and the share of polysilicon capacity set to increase, reaching nearly 951 TP3T by 2030," the IEA said.
In addition, the report provides data on levelized manufacturing costs, upfront and operating costs, and national manufacturing incentives. According to the report, JinkoSolar's 56 GW solar module plant built in the Shanxi Comprehensive Reform Demonstration Zone is cheaper than the national average.
Although the estimated costs are not final, the facility is expected to reach $7.8 billion, or $140/kW for full-chain solar PV manufacturing, compared to China's national average of $185/kW," the IEA said. (This article was compiled from pv-magazine, reprinted with permission)
