Date: October 19, 2025
Sector: Power Equipment & New Energy
Analyst Team: Deng Yongkang, Wang Yiru, Li Jia, et al. (Minsheng Securities Research Institute)
Executive Summary
The Power Equipment and New Energy sector experienced a correction during the week of October 13–17, 2025, declining by 5.30%, underperforming the Shanghai Composite Index (-1.47%). Despite the broader market pullback, structural divergences within sub-sectors are becoming increasingly pronounced. Solar energy emerged as the relative outperformer (+0.52%), driven by signs of price stabilization across the photovoltaic (PV) supply chain. Conversely, industrial automation (-7.12%) and lithium batteries (-6.41%) faced significant pressure amid profit-taking and macroeconomic uncertainties.
This week’s report highlights three pivotal developments shaping the investment landscape for Q4 2025 and beyond:
- Solid-State Battery (SSB) Inflection Point: China has achieved multiple critical breakthroughs in SSB technology, addressing longstanding bottlenecks in interface stability, energy density, and safety. Academic teams from Tsinghua University, the Chinese Academy of Sciences (CAS) Institute of Metal Research, and CAS Institute of Physics have demonstrated prototypes with energy densities exceeding 604 Wh/kg, exceptional flexibility (20,000 bends), and robust cycle life without high external pressure. These advancements accelerate the commercialization timeline, with global SSB shipments projected to surge from 34 GWh in 2026 to 614 GWh by 2030.
- Photovoltaic Supply Chain Stabilization: After months of volatility, PV prices are showing signs of bottoming out. Silicon material prices have stabilized, with tier-1 manufacturers holding firm at RMB 55/kg. Silicon wafer production schedules for October have increased, yet the market maintains a "price-support" stance. While some niche segments like 210RN cells face slight downward pressure due to oversupply, mainstream N-type products (183N/210N) remain stable. The industry’s self-discipline initiatives and potential supply-side reforms are beginning to anchor market expectations.
- Grid Investment Milestone: State Grid Corporation of China (SGCC) is on track to exceed an annual fixed asset investment of RMB 650 billion for the first time in 2025. With RMB 420 billion already invested in the first nine months (a 8.1% YoY increase), the acceleration in Ultra-High Voltage (UHV) projects and distribution network upgrades provides a deterministic revenue stream for power equipment manufacturers.
Investment Stance: We maintain a "Recommend" rating on the sector. We advise investors to pivot towards companies with technological moats (SSB leaders), beneficiaries of grid capex expansion (UHV and transformers), and PV players positioned to benefit from supply-side consolidation and overseas demand resilience.

- Tian Nai Technology (300693.SZ): Carbon nanotubes are critical for enhancing conductivity in solid electrolytes. As SSB adoption grows, demand for high-performance conductive agents will surge.
3. Photovoltaics: Navigating the Bottom
The PV sector is likely at or near its cyclical bottom. The stabilization of silicon prices and the industry's move towards self-discipline are positive signals.
- Action: Accumulate positions in integrated leaders with strong balance sheets and overseas exposure. Avoid pure-play manufacturers in highly commoditized segments (e.g., standard PERC modules) unless they have a clear cost advantage.
- Focus on Inverters & Storage: The inverter segment, particularly those with strong storage integration (Sungrow, Deye), continues to enjoy better margins and growth visibility than module makers. The global transition to renewable energy requires grid-forming inverters and storage solutions, creating a durable demand tailwind.
4. Grid Equipment: The "Safe Haven" with Growth
With SGCC investment hitting record highs, the power equipment sector offers a rare combination of policy certainty and growth.
- UHV Boom: The completion of major UHV DC lines and the start of new AC projects directly benefit Pinggao Electric (GIS switches) and Xuji Electric (DC control valves, converters).
- Distribution Upgrade: The push for smart grids and distributed energy integration favors NARI Technology and Sifang Shares.
- Export Alpha: Companies like Jinpan Technology and Sieyuan Electric are successfully expanding in Europe and North America, leveraging their cost advantages and rapid delivery capabilities. This export growth provides a hedge against domestic saturation.
