Core Viewpoint - The solar photovoltaic demand in Q2 2025 has rapidly increased due to domestic rush installations, leading to a recovery in revenue and gross margins for major industry chain companies. Additionally, the easing of U.S. tariffs has significantly improved profitability in the U.S. market after companies streamlined their supply chains [1] Industry Chain Summary - The revenue of the main industry chain has increased, and gross margins have generally recovered, although there is differentiation among segments and companies. The downstream battery and module prices have risen quickly due to the rush installations, while the performance of silicon materials and wafers continues to decline marginally. Overall gross margin recovery is noted, but the increase in shipment volumes has not significantly reduced overall losses in the sector [1] - In Q2 2025, the output of slurry slightly increased quarter-on-quarter, but performance was heavily impacted by costs. The introduction of low-cost metal slurry production is expected to provide significant revenue and profit growth opportunities for slurry companies. The profitability of junction boxes, frames, and solder strips has been under pressure, while overseas production capacity for frames has shown strong contributions. Glass and film prices and profits have recovered due to domestic rush installations, with strong demand for centralized inverters and energy storage systems [2] Financial Outlook - The financial statements for Q3 2025 are expected to show further recovery, with a focus on the progress of reducing internal competition. Since July, the price of silicon materials has risen significantly, and downstream silicon wafers and battery modules have experienced varying degrees of price adjustments. The overall profit and operating cash flow for the sector are anticipated to improve further in Q3 2025, although the performance of the module segment may face some pressure quarter-on-quarter. Glass and film prices are expected to gradually rise above the production cost line of second-tier leading companies [3] Recommended Companies - Recommended companies include: - Silicon material segment: Tongwei Co., Ltd.
