Analyst: Zhang Xinyi (S1490522090001)

Executive Summary

The Chinese photovoltaic (PV) sector demonstrated resilience and relative outperformance during the week of December 8–12, 2025. The Shenwan PV Equipment Index rose by 0.77%, contributing to the broader Power Equipment Index’s gain of 1.19%, which ranked fifth among all 31 Shenwan industry indices and outperformed the CSI 300 Index by 1.27 percentage points. This performance underscores a shifting market sentiment driven by macro-policy support and stabilizing supply-side dynamics.

Our analysis indicates that the PV industry is at a critical inflection point. The central government’s recent emphasis on curbing "involutionary" (destructive) competition, coupled with regional "15th Five-Year Plan" proposals from key provinces like Hainan and Jiangsu, signals a structured transition toward high-quality development. Simultaneously, main-chain prices have largely stabilized, with silicon material and module prices holding steady, although slight pressure remains on silicon wafers and glass. Notably, silver paste prices surged by 11.4%, reflecting cost pressures in metallization processes that may accelerate technological substitution toward low-silver or copper-plating solutions.

We maintain an Overweight rating on the sector. The investment thesis is anchored in three pillars:
1. Profitability Repair via Supply-Side Reform: Policy directives aimed at eliminating inefficient capacity and standardizing market competition are expected to restore healthy margins for leading manufacturers.
2. Technological Alpha: Opportunities arising from iterative technology upgrades (e.g., TOPCon, HJT, BC) favor companies with superior R&D capabilities and equipment leadership.
3. Demand Beta: Marginal improvements in demand expectations, driven by large-scale infrastructure projects (such as the Tianwan offshore PV project) and global energy transition trends.

Investors should focus on polysilicon leaders, module integrators with strong brand channels, and equipment manufacturers enabling next-generation efficiency gains. While short-term volatility may persist due to policy implementation timelines, the long-term trajectory supports consolidation around high-efficiency technologies and market leaders.

Key Takeaways

1. Market Performance: Relative Strength Amidst Broad Consolidation

During the reporting period (December 8–12, 2025), the broader A-share market exhibited mixed performance, with the CSI 300 Index declining slightly by -0.08%. However, the Power Equipment sector emerged as a clear outlier, delivering robust returns.

• Sector Outperformance: The Shenwan Power Equipment Index increased by +1.19%, ranking 5th out of 31 industries. It outperformed the benchmark CSI 300 by 1.27 pcts.
• Sub-Sector Divergence: Within the power equipment landscape, performance was differentiated:
  • Outperformers: Other Power Equipment II (+5.31%), Grid Equipment (+3.65%), and Wind Power Equipment (+1.94%).
  • PV Performance: The PV Equipment Index rose by +0.77%, demonstrating stability despite headwinds in other sub-sectors like Batteries (-0.07%) and Motors II (-0.99%).
• Individual Stock Movements:
  • Top Gainers: Maxwell Technologies (Maiwei Shares), Aerospace M&E, Polymer Materials, Microdao Nano, and DKEM (Dike Shares). These gains are largely attributed to investor preference for equipment makers benefiting from technology iteration and materials suppliers with niche competitive advantages.
  • Top Decliners: Saiwu Technology, TCL Zhonghuan, Sungrow Power, Mingguan New Material, and Mubang High-Tech. The decline in major integrated players like TCL Zhonghuan and Sungrow suggests lingering concerns over margin compression in the wafer and inverter segments, respectively, or profit-taking after recent rallies.

2. Supply Chain Price Analysis: Stabilization with Structural Cost Pressures

According to data from Datayes (as of December 3, 2025), the PV supply chain prices have entered a phase of stabilization, indicating that the aggressive price wars of previous quarters may be bottoming out. However, specific inputs show divergent trends that will impact manufacturer margins differently.

A. Main Chain Prices: Holding Steady

• Polysilicon: The transaction price remained flat at 51 CNY/kg. This stability is crucial for upstream producers, suggesting that production cuts and inventory adjustments have balanced supply and demand at this price level. Prices below this threshold would threaten the cash costs of many producers, implying a strong floor.
• Solar Cells: Prices held steady at 0.28 CNY/W. This indicates that cell manufacturers are successfully passing through stable silicon costs while facing consistent downstream demand.
• Modules: Module prices remained unchanged at 0.69 CNY/W. This price point is near the historical low, limiting downside risk but also capping immediate margin expansion for integrators unless non-silicon costs decrease.
• Silicon Wafers: In contrast to other segments, wafer prices dipped by 0.05 CNY/piece to 1.20 CNY/piece. This slight decline suggests that wafer capacity utilization may still exceed optimal levels, or that downstream buyers are exerting pressure on this specific link in the chain.

B. Auxiliary Materials: Mixed Signals

• Photovoltaic Glass: Prices for both 3.2mm and 2mm glass decreased by 0.5 CNY/sqm, settling at 19.5 CNY/sqm and 12 CNY/sqm, respectively. This softness reflects adequate supply and potentially slower-than-expected installation pacing in certain regions, providing a slight cost relief to module makers.
• Silver Paste: A significant anomaly was observed in silver paste prices, which surged by 11.4% to 13,958 CNY/kg.
  • Implication: Silver is a critical cost component for PERC, TOPCon, and HJT cells. A double-digit increase in silver prices directly erodes the gross margins of cell manufacturers.
  • Strategic Shift: This price spike accelerates the economic imperative for silver reduction technologies (such as multi-busbar, SMBB, and plating techniques) and the adoption of copper electroplating where feasible. Equipment vendors specializing in low-silver consumption processes (e.g., Maxwell Technologies, Microdao Nano) stand to benefit from this cost-driven technology shift.

3. Policy & Macro Drivers: The "Anti-Involution" Mandate

The most significant catalyst for the sector’s medium-term outlook stems from the Central Economic Work Conference held on December 10–11, 2025. The conference’s directives provide a top-down framework for resolving the industry’s chronic overcapacity and profitability issues.

A. Curbing "Involutionary" Competition

The conference explicitly called for "deep rectification of 'involutionary' competition" and the formulation of regulations for a national unified market.
* Interpretation: "Involution" in the PV context refers to price wars driven by excessive, often subsidized, capacity expansion that leads to industry-wide losses. By targeting this behavior, the central government aims to enforce stricter environmental, energy consumption, and technical standards. This will likely force the exit of inefficient, high-cost producers and prevent local governments from blindly subsidizing new, redundant capacity.
* Impact: This is a bullish signal for industry leaders with scale, technology, and cost advantages. It facilitates market share consolidation and pricing power restoration.

B. Green Transition and Energy Security

The conference reaffirmed the "Dual Carbon" goals as a leading principle, emphasizing:
* Acceleration of the new energy system construction.
* Expansion of green electricity application.
* Strengthening the national carbon emissions trading market.
* Deepening energy-saving and carbon-reduction transformations in key industries.

This political commitment ensures that long-term demand for PV remains robust, supported by state-level infrastructure spending and regulatory mandates for green energy adoption.

C. Regional Planning: Hainan and Jiangsu "15th Five-Year Plan" Proposals

Local governments are aligning with national directives, providing specific visibility into future demand clusters.

• Hainan Province:

  • Focus on offshore wind and distributed PV.
  • Construction of a source-grid-load-storage integrated new power system.
  • Development of the Hainan-Guangdong HVDC transmission line for flexible mutual aid, enhancing the ability to consume and transmit renewable energy.
  • Emphasis on new energy storage and pumped hydro, creating ancillary opportunities for PV+Storage projects.

• Jiangsu Province:

  • Safe and orderly development of nuclear power, hydrogen, and deep-sea offshore wind.
  • Promotion of integrated wind-solar-hydro-thermal-storage development.
  • Transformation of coal power from base-load to supportive/regulatory power, which enhances the grid’s ability to absorb intermittent renewable energy.
  • Implementation of renewable energy consumption commitments for new projects, guaranteeing a baseline demand for green power certificates and PV installations.
  • Exploration of electricity market mechanisms that reflect the value of different quality power sources, potentially premium-pricing stable, high-efficiency PV generation.

It opens a new growth avenue for PV developers and EPC contractors capable of handling complex marine environments and multi-energy integration. Companies with expertise in corrosion-resistant modules and offshore engineering will benefit.

B. Global Employment Trends (IEA Report)

The International Energy Agency (IEA) released the World Energy Employment Report 2025, highlighting the solar sector’s role as a primary job creator.
* Job Growth: Solar energy contributed 40% of all new jobs in the global power sector in 2024.
* Scale: The global energy workforce reached 76 million, with solar manufacturing (inverters, panels, batteries) employing approximately 3.5 million people.
* China’s Dominance: China accounts for 60% of the global solar workforce, reinforcing its position as the undisputed center of the PV supply chain.
* Labor Structure: Two-thirds of solar jobs are in development and installation, indicating that downstream EPC and O&M (Operations & Maintenance) services represent a significant and growing portion of the value chain, beyond just manufacturing.

Risks / Headwinds

While the outlook is positive, investors must remain cognizant of the following risks that could derail the recovery trajectory:

1. Raw Material Price Volatility:

   • The recent 11.4% surge in silver paste prices poses an immediate margin risk for cell manufacturers. If silver prices remain elevated or continue to rise due to macroeconomic factors or industrial demand (e.g., from the EV or electronics sectors), it could compress profits unless fully passed down to module buyers, which may dampen demand.
   • Fluctuations in polysilicon prices, while currently stable, could re-emerge if supply discipline breaks down or if unexpected production disruptions occur.

2. Project Execution and Start-up Delays:

   • Despite policy support, the actual pace of project commencement ("start-ups") may lag expectations. Factors such as land acquisition hurdles, grid connection approvals, and financing constraints for private developers could delay revenue recognition for EPC and equipment firms.
   • The complexity of new formats like offshore PV (e.g., Tianwan project) introduces execution risks related to weather, logistics, and technical challenges.

3. Intensifying Trade Frictions:

   • As China maintains its dominance in the global PV supply chain (60% of jobs, majority of manufacturing), trade protectionism in key markets (US, EU, India) remains a persistent threat.
   • Potential new tariffs, anti-circumvention investigations, or local content requirements could restrict export volumes for Chinese module makers, forcing them to rely more heavily on the domestic market where competition is fiercer.
   • Geopolitical tensions could disrupt supply chains for critical non-Chinese components or hinder overseas expansion plans.

4. Policy Implementation Lag:

   • While the Central Economic Work Conference set a strong tone against "involution," the specific regulatory measures and enforcement mechanisms take time to materialize. In the interim, market participants may continue aggressive pricing strategies, delaying the expected profitability repair.

Rating / Sector Outlook

Rating: Overweight (Positive)

We maintain an Overweight stance on the Photovoltaic sector. The combination of policy-driven supply-side cleanup, stabilizing prices, and emerging demand from innovative applications (offshore PV, integrated energy systems) creates a favorable risk-reward profile for institutional investors.

Sector Outlook:
* Short-Term (1-3 Months): Expect continued volatility as the market digests the implications of the Central Economic Work Conference and monitors the implementation of anti-competition measures. Price stability in silicon and modules provides a floor for valuations.
* Medium-Term (6-12 Months): Anticipate a gradual improvement in industry profitability as inefficient capacity exits the market. Leaders with technological moats (high-efficiency cells, low-silver tech) will capture disproportionate market share.
* Long-Term (1-3 Years): The sector is poised for sustainable growth driven by the global energy transition, with China remaining the core manufacturing hub. The integration of PV with storage, hydrogen, and nuclear (as seen in Tianwan) will create new, higher-value business models.

Investment Strategy:
1. Focus on Supply-Side Beneficiaries: Prioritize companies that will benefit from the elimination of backward capacity. This includes top-tier polysilicon producers with low cash costs and leading module integrators with strong balance sheets.
2. Technological Alpha: Invest in equipment and material suppliers enabling the next generation of PV technology. Specifically, look for companies involved in low-silver metallization, copper plating, and high-efficiency cell equipment (TOPCon/HJT/BC). The rise in silver prices makes these technologies economically urgent.
3. New Application Leaders: Monitor companies with expertise in offshore PV, BIPV (Building-Integrated PV), and PV+Storage integration, as these segments are receiving targeted policy support in provinces like Hainan and Jiangsu.

Investment View

Core Investment Logic

The PV industry is transitioning from a phase of "scale-driven expansion" to "quality-driven consolidation." The investment narrative has shifted from pure volume growth to profitability repair and technological leadership.

1. Policy Put Option: The central government’s explicit stance against "involutionary competition" acts as a policy put option for industry margins. By enforcing a national unified market and stricter standards, the state is effectively managing supply, which should prevent prices from falling below sustainable levels. This reduces the downside risk for equity valuations.
2. Cost-Push Innovation: The sharp increase in silver paste prices is not merely a cost headwind but a catalyst for technological disruption. Companies that can deliver solutions to reduce silver consumption (e.g., specialized pastes, printing equipment, plating tools) will see accelerated order books. This creates a distinct alpha opportunity within the equipment and materials sub-sectors.
3. Demand Diversification: The success of the Tianwan offshore PV project and the regional plans for integrated energy systems demonstrate that demand is diversifying beyond traditional ground-mounted utility projects. This diversification reduces reliance on any single market segment and opens up higher-margin niches for specialized players.

Recommended Focus Areas

Conclusion

The week of December 8–12, 2025, marked a pivotal moment for the Chinese PV industry. The convergence of stable main-chain prices, decisive policy intervention against destructive competition, and breakthroughs in new application scenarios provides a solid foundation for a sector recovery.

While risks such as raw material volatility (specifically silver) and trade friction persist, the structural improvements in supply discipline and the relentless drive for technological efficiency position the sector for sustainable long-term growth. Institutional investors are advised to overweight high-quality leaders and technology enablers, capitalizing on the dual tailwinds of policy-supported consolidation and innovation-driven demand.
