电新公用环保行业周报：聚焦“防内卷”政策投资策略，优先推荐风电整机环节-20250707

Overall Viewpoint - The report emphasizes the "anti-involution" policy investment strategy, prioritizing recommendations for the wind power complete machine segment [3][4] - The government is focusing on regulating low-price disorderly competition in industries such as photovoltaics, energy storage, and new energy vehicles, with a significant emphasis on the orderly exit of backward production capacity [3][4] - The report suggests that the recent policies aim to combat deflation through price increases and assist local governments in debt reduction, while the exit of backward production capacity will be gradual rather than rapid [3] Photovoltaics - The report highlights that the prices of photovoltaic glass and silicon materials are relatively elastic, but profitability after price increases is generally moderate. It suggests focusing on policy and price catalysts [3] - Integrated companies with low price-to-book ratios are expected to benefit from overall valuation increases in the sector. New technologies like BC and perovskite have certain price elasticity, with better profitability in overseas markets [3] - Recommended companies include Tongwei Co., Ltd., TBEA Co., Ltd., Xinte Energy (H), GCL-Poly Energy (H), Aiko Solar Energy, JA Solar Technology, Trina Solar, Jinjing Technology, and Juhua Group [3] Wind Power - Wind power complete machine prices are stabilizing and will benefit from the "anti-involution" policy. The complete machine segment has significant earnings elasticity, with larger units and cost reductions in components expected to improve profitability in 2026 [4] - The report notes that the 136 document reshapes the logic of new energy installations, with expectations for wind power development and power station sales to recover [4] - Key companies to watch include Windar Photonics, Mingyang Smart Energy, and Goldwind (A+H). The report also highlights investment opportunities in the bearing segment and European offshore wind products [4] Energy Storage - The market has a generally positive outlook for large-scale energy storage in Europe and overseas commercial storage, but there are still divergences regarding profitability improvements in domestic large-scale storage post-136 document [5] - The report indicates that the good bidding data for large-scale storage in May-June is related to the "531" rush installation and independent storage competition [5] - Companies to focus on include Haibo Sichuang, Sungrow Power Supply, Goodwe, and Deye [5] Solid-State Batteries - The report mentions a potential pullback risk in the solid-state battery sector, with some companies in the copper foil segment experiencing stock price rebounds following the "anti-involution" policy [4] - It suggests that while there are risks in the materials sector related to solid-state batteries, mid-term capital expenditures are expected to rise due to manufacturers actively advancing semi-solid and all-solid experimental lines [4] - Recommended companies include Honggong Technology, Naconor, Winbond Technology, and Xiamen Tungsten [4] Public Utilities - The report states that as of July 4, 2025, the price of 5500 kcal thermal coal at Qinhuangdao Port is 622 RMB/ton, a slight increase from the previous week [35] - The maximum national power load reached 1.465 billion kilowatts, a historical high, with significant increases in regions like Jiangsu, Anhui, Shandong, Henan, and Hubei [35]
