[SMM Silicon-Based PV Morning Meeting Minutes: Polysilicon Prices Temporarily Stable, Module Prices Relatively Weak] Last week, China's module prices were basically stable, but amid this stability there was a tug-of-war between upstream and downstream. Currently, distributed and some centralized procurement plans are increasing, but for current module prices, negotiation and pushing for lower prices remain the main approach. However, on the module side, due to support from the cost side, especially silver prices, and strengthened support from solar cell prices, maintaining stable prices remains the priority. Currently, distributed Topcon 183, 210R, and 210N high-efficiency modules are quoted at 0.7445 Yuan/W, 0.752 Yuan/W, and 0.755 Yuan/W respectively, while centralized Topcon 182/183 and 210N high-efficiency modules are quoted at 0.7235 Yuan/W and 0.7435 Yuan/W respectively.

SMM statistics showed that as of May 14, the total social inventory of silicon metal in major regions was 554,000 mt, an increase of 3,000 mt WoW. (Note: Excluding Inner Mongolia, Gansu, Ningxia, and other regions)

The year 2026 marks the opening year of the "15th Five-Year Plan" period. Against the backdrop of intensifying global macro volatility and the deepening advancement of high-quality development in China, the zinc industry is undergoing profound transformation: tightness on the ore side and the release of smelting capacity are creating structural tension, divergence between domestic and overseas inventories reflects the complex dynamics of supply-demand rebalancing, and technological innovation is becoming the key momentum for resolving contradictions and reshaping the landscape. Key areas under the "15th Five-Year Plan" such as new energy and new-type infrastructure are injecting new momentum into traditional zinc consumption, while green, low-carbon, and circular economy principles are accelerating the restructuring of industrial logic driven by technological innovation. With the joint support of upstream and downstream enterprises in the zinc industry, industry associations, and relevant parties, SMM is about to hold the 2026 SMM Zinc Industry Conference & the 8th Hot-Dip Galvanizing Industry Development and Technological Innovation Forum & the 14th Zinc Salt, Zinc Oxide and Zinc Secondary Resources Development Forum & the Zinc-Based Materials Development Forum on August 6-8 in Qingdao, Shandong. Themed "Converging Zinc Momentum · Building Zinc Industry · Embarking on a New Journey," the conference is driven by the dual engines of macro perspectives and fundamental analysis, closely aligned with the "15th Five-Year Plan" high-quality development mainline, focusing on four major dimensions: macro policies, supply-demand patterns, global trade, and technological innovation. It aims to drive cost reduction and efficiency improvement through technological breakthroughs, respond to market fluctuations through collaborative innovation, and jointly chart a new blueprint for high-quality and sustainable development of the zinc industry.
