电力设备与新能源行业8月第5周周报：硅片价格酝酿涨价，多家企业固态电池发布

Investment Rating - The report maintains an "Outperform" rating for the power equipment and new energy sector [1]. Core Insights - The report highlights that silicon wafer prices are expected to rise, with several companies announcing solid-state battery releases. The supply-demand relationship in the photovoltaic sector is gradually easing, and it is anticipated that the silicon material segment will be the first to complete capacity clearance. Longi has raised silicon wafer prices, which may positively impact industry profitability. The demand for inverters remains strong, and it is recommended to prioritize segments with favorable industry structures and clear supply optimization [1]. - In the wind power sector, domestic offshore wind bidding and construction are expected to progress steadily, with plans for deep-sea demonstration projects gradually being introduced. The overseas market is anticipated to see demand release starting in 2025, driven by declining interest rates and project planning, suggesting a focus on tower foundations and submarine cable segments that benefit from offshore wind and overseas expansion logic [1]. - In the electric vehicle sector, material segments continue to face profitability pressures, but it is expected that material price declines will ease in the second half of the year, leading to potential profitability recovery. The solid-state battery industrialization is accelerating, and companies with layouts in relevant fields are expected to benefit [1]. - The domestic power equipment sector is continuously promoting power system reforms, with new policies expected to accelerate the construction of ultra-high voltage and main grid infrastructure, maintaining high demand for related grid equipment. The overseas demand for grid renovation is also robust, suggesting a focus on main grid segments benefiting from ultra-high voltage demand and distribution network segments with overseas expansion logic [1]. - The hydrogen energy sector is seeing continuous policy support for industrialization, with recommendations to focus on electrolyzer manufacturers with cost and technology advantages, as well as companies benefiting from hydrogen infrastructure construction [1]. Market Performance - The power equipment and new energy sector rose by 4.32% this week, outperforming the broader market. The wind power sector increased by 7.41%, while the photovoltaic sector rose by 7.34% [1][7].
