Core Viewpoint - The domestic photovoltaic demand in Q3 2025 has weakened due to the end of the rush for installation, but the financial performance of the main industry chain and glass segments has significantly improved, with a focus on potential price increases for components and further profit release for silicon material companies in Q4 2025 [1] Industry Summary - **Main Industry Chain Recovery**: The upstream of the main industry chain has significantly recovered, while the component prices are yet to show a clear upward trend. After the end of the rush for installation in the first half of 2025, photovoltaic demand has weakened, but the performance of silicon materials and silicon wafers has greatly improved due to anti-involution efforts [2] - **Stable Processing Fees and Glass Profit Improvement**: The shipment of slurry in Q3 2025 has slightly increased quarter-on-quarter, with overall gross margins remaining stable. Attention is drawn to the pace of mass production of low-cost metal slurry from this year to the first half of next year, as well as the second growth curve of leading companies. Leading glass and film companies have strengthened their advantages due to a higher proportion of overseas shipments and continuous cost reductions [3] - **High Demand for Energy Storage**: Despite a certain degree of weakness in inverter exports due to the European off-season in Q3 2025, domestic energy storage bidding has increased significantly year-on-year, driving demand for centralized inverters and energy storage systems.
