China is facing a recycling challenge and environmental strain caused by large numbers of end-of-life solar panels after a decade of rapid photovoltaic (PV) industry expansion. . PV panels, which convert solar energy into electric energy, have a lifespan of around 30 years. 17, 2015, in Yantai, Shandong Province, China. While they can continue to produce electricity after this period, their efficiency decreases. . Along with the rapid expansion of China's new-energy industries, a growing volume of wastes, including discarded batteries, solar panels and wind turbine blades, have caused concern, with the country's environmental authorities stepping up regulatory measures and formulating specific disposal. . However, the life span of photovoltaic (PV) modules is 25 to 30 years, and the rapid development of installed capacity indicates that a large number of PV modules will be decommissioned in the future. Therefore, the ongoing treatment of the scrapped PV waste cells in the near future requires urgent. .

CEA said an additional roughly 10 GW of cell capacity is under construction or in a late stage with likely operational dates in 2026, with potential for more “stealth” cell plants in development for module suppliers planning in-house cell procurement. is on track to reach 13 GW of cell manufacturing capacity and 65 GW of module assembly in 2025, said a report from Clean Energy Associates. Clean Energy Associates (CEA). . Supply Chain Gaps Remain Critical: While module assembly is strong, wafer production represents the biggest weakness in the US solar supply chain, with virtually no commercial production currently operational, forcing even “Made in USA” panels to rely on imported components. Policy-Driven Success:. . Solar panels are central to the clean energy transition, but like most green technologies, there are behind-the-scenes trade-offs. Solar panel manufacturing involves complex processes, material supply chains, and rigorous durability needs. This is more than double China's share of global PV demand.
