光伏行业周报（20250825-20250831）：组件成本支撑增强，价格或将继续博弈-20250901

Investment Rating - The report maintains a "Recommendation" rating for the photovoltaic industry, expecting the industry index to outperform the benchmark index by more than 5% in the next 3-6 months [5][61]. Core Insights - The report highlights that the cost support for components has strengthened, leading to potential price negotiations in the market. Since late August, prices for silicon materials, silicon wafers, and battery cells have increased, while auxiliary materials like photovoltaic glue film and glass have also seen price hikes, providing cost support [2][12]. - The report indicates that the main material prices, such as polysilicon and silicon wafers, have shown upward trends, with polysilicon prices for dense and granular materials averaging 46.0 CNY/kg, reflecting a week-on-week increase of 4.5% [3][11]. - The battery cell prices have varied by size, with 183N and 210N battery cells seeing price increases of approximately 0.005 CNY/W due to a relatively balanced supply-demand situation [11][38]. Summary by Sections 1. Component Cost Support and Price Negotiation - Silicon material prices have stabilized, with September production expected to be around 125,000 to 130,000 tons. The average transaction price for N-type recycled material is 47,900 CNY/ton, unchanged week-on-week, while N-type granular silicon has increased by 2.2% to 47,000 CNY/ton [11][12]. - Silicon wafer prices have slightly increased due to cost support, with a strong willingness to maintain prices amid rising upstream silicon material costs. The market atmosphere remains positive due to sustained demand from the downstream battery sector [11][12]. 2. Market Performance Review - The report notes that the overall industry index rose by 5.90% this week, with the electric equipment industry index increasing by 3.99%. The top-performing sectors included telecommunications and non-ferrous metals, while banking and coal sectors lagged [13][16]. - In the electric equipment sector, the top five companies by stock performance included Tonghe Technology (+50.29%) and Maguimi (+29.09%), while the worst performers included Rongyu Group (-10.93%) and Jinguang Co. (-26.19%) [19][23]. 3. Industry Price Trends - The report provides detailed pricing for various components, indicating that the average price for 182-183.75mm N-type silicon wafers is 1.25 CNY/piece, with a week-on-week increase of 4.2%. The prices for TOPCon battery cells also showed slight increases [3][38]. - Auxiliary materials such as photovoltaic glass and EVA films have maintained stable prices, with 3.2mm coated photovoltaic glass priced at 18.5-19.0 CNY/m² and transparent EVA film at 5.52 CNY/m² [4][44].
