JinkoSolar Accelerates Mass Production of 640 W+ TOPCon Modules

Leading PV and ESS supplier JinkoSolar has announced that it is accelerating the mass production of its high-power TOPCon solar modules above 640 W. During a recent roadshow, the company said its Shangrao and Shanxi facilities have completed capacity upgrades. The company expects 640 W+ products to account for 40% to 50% of its total production capacity. In 2026, most capacity will support mainstream modules rated at 650 W to 670 W. The company has already started partial deliveries of modules over 640 W in Q3 this year, and anticipates that most orders next year will shift to these high-power models. JinkoSolar expects its advanced production lines to reach approximately 670 W next year and potentially achieve 680 W to 700 W in the next 2 to 3 years.

Earlier this month, JinkoSolar announced that cumulative shipments of its Tiger Neo series TOPCon module series have surpassed 200 GW. At SNEC 2025, JinkoSolar showcased its Tiger Neo 3.0 series module, rated at 670 W power and 24.8% efficiency.
