AI Summary

Silver released from retired PV modules in China is projected to peak at about 739 metric tons per year in 2044, nine years before the peak of retired capacity at 70.77 GW in 2053, according to a Nankai University study. The earlier, smaller installation cohorts contained more silver per watt than later, larger cohorts, creating the mismatch. Between 2018 and 2025, average silver intensity fell 62 % from 23.33 mg/W to 8.86 mg/W, while annual silver entering new installations rose 170 % from roughly 1,150 MT to 3,109 MT. By the end of 2025, China’s installed fleet held 17,784 MT of silver, representing 99.5 % of all silver installed since 2000.
