Rating: Market Perform - A (Maintained)
Analysts: Xiao Suo, Jia Huilin

Executive Summary

The Chinese photovoltaic (PV) sector in September 2025 presented a dichotomy between domestic installation slowdowns and robust export performance. While domestic new installations contracted significantly year-over-year (YoY), cumulative growth remains strong, supported by sustained demand in overseas markets. Specifically, module and inverter exports continued to demonstrate resilience, with module export volumes rising nearly 47% YoY and inverter export values maintaining positive growth despite sequential declines.

Domestically, solar power generation capacity utilization remains high, with solar output accounting for 5.63% of total industrial electricity generation in September. The industry is currently navigating a complex landscape characterized by shifting regional demand patterns—particularly strength in Latin America, Africa, and Oceania for inverters—and technological transitions toward BC (Back Contact) cells.

We maintain our "Market Perform - A" rating for the solar sector. The investment thesis has shifted from broad-based expansion to selective opportunities driven by technological innovation (BC technology), supply-side consolidation, energy storage integration, and overseas market penetration. We recommend investors focus on leaders in niche high-growth segments while monitoring risks related to global trade policies and domestic pricing volatility.

Key Takeaways

1. Domestic Installations: Short-Term Volatility Amidst Strong Cumulative Growth

September data indicates a notable contraction in monthly domestic installations, likely due to seasonal factors, grid connection bottlenecks, or temporary policy adjustments. However, the year-to-date (YTD) trajectory remains firmly positive.

• September Performance: New domestic PV installations reached 9.7 GW, representing a 53.8% YoY decline. However, this figure marks a 31.2% month-over-month (MoM) increase, suggesting a potential stabilization or recovery trend entering the fourth quarter.
• Cumulative Strength: From January to September 2025, cumulative new installations totaled 240.27 GW, a substantial 49.3% YoY increase. This underscores that the long-term adoption curve in China remains steep, despite monthly fluctuations.

Analyst Note: The sharp YoY drop in September should be interpreted in the context of the high base effect from previous years and potential timing shifts in project commissions. The robust YTD growth of ~49% confirms that domestic demand fundamentals remain intact. Investors should watch Q4 data closely to confirm if the MoM rebound sustains into year-end rush periods.

2. Module Exports: Volume and Value Divergence Resolves Upwards

Export data for September reveals a healthy external demand environment, particularly in terms of volume. The divergence between export value and volume metrics suggests stabilizing average selling prices (ASPs) or a shift in product mix toward higher-efficiency modules.

• Value vs. Volume Dynamics: The 39.0% YoY surge in export value alongside a 46.8% YoY surge in volume indicates that the severe price erosion seen in earlier periods may be moderating. The cumulative export value still shows a 13.3% decline YoY, reflecting the lagged impact of lower prices earlier in the year, but the monthly momentum is clearly positive.
• Regional Trends: While specific regional breakdowns for modules were not detailed in the headline figures, the overall volume growth of 4.6% YTD suggests that international markets are absorbing Chinese supply effectively, offsetting any potential softness in traditional strongholds like Europe.

3. Inverter Exports: Geographic Diversification Drives Growth

Inverter exports exhibited a mixed picture in September, with overall value growing YoY but declining sequentially. The key story here is the significant geographic rotation in demand.

• Overall Performance:

  • September Export Value: RMB 5.08 Billion (+5.0% YoY, -19.2% MoM).
  • Cumulative (Jan-Sep): RMB 48.49 Billion (+7.7% YoY).

• Regional Breakdown (September):
  The data highlights a stark contrast between mature markets experiencing corrections and emerging markets driving growth.

  Region	Export Value (RMB Billion)	YoY Change	MoM Change	Trend Analysis
  Oceania	4.6	+288.3%	-7.2%	Explosive Growth: Likely driven by large-scale project completions or accelerated residential uptake in Australia/NZ.
  Latin America	5.3	+36.6%	-5.1%	Strong Momentum: Continued infrastructure development and favorable policy environments in key LATAM countries.
  Africa	3.7	+22.7%	-13.4%	Steady Expansion: Growing off-grid and mini-grid solutions contributing to demand.
  Europe	18.8	-9.5%	-30.1%	Correction Phase: Inventory digestion and slower installation rates continue to weigh on exports.
  Asia	16.9	-3.5%	-12.7%	Stable/Soft: Minor contraction, possibly due to seasonal factors or local manufacturing ramp-ups.
  North America	1.5	-24.8%	-17.0%	Policy Headwinds: Trade barriers and regulatory uncertainties continue to suppress direct exports.

Strategic Insight: The 288.3% YoY surge in Oceania and 36.6% growth in Latin America are critical drivers offsetting the declines in Europe and North America. This geographic diversification reduces reliance on any single market and highlights the global competitiveness of Chinese inverter manufacturers. Companies with strong distribution networks in LATAM, Africa, and Oceania are better positioned to capture alpha in the current cycle.

4. Power Generation: Solar’s Rising Share in the Energy Mix

Solar power continues to cement its role as a pillar of China’s energy security and transition.

• Generation Volume: In September 2025, above-scale solar power generation reached 46.48 billion kWh, a 21.1% YoY increase.
• Market Share: Solar accounted for 5.63% of total above-scale industrial electricity generation, a slight sequential decrease of 0.12 percentage points (pct), likely due to seasonal variations in sunlight hours compared to summer peaks.
• Comparative Context:
  • Total Industrial Power Generation: 826.2 billion kWh (+1.5% YoY).
  • Thermal Power: -5.4% YoY (Continuing structural decline).
  • Hydropower: +31.9% YoY (Strong recovery, likely due to favorable hydrological conditions).
  • Nuclear Power: +1.6% YoY (Stable baseline load).
  • Wind Power: -7.6% YoY (Potential resource variability).

The 21.1% growth in solar generation outpaces the total power generation growth (1.5%) significantly, indicating that solar is gaining share at the expense of thermal and, to some extent, wind. This reinforces the long-term utility case for solar assets and supports the revenue visibility of independent power producers (IPPs) and equipment suppliers.

Risks / Headwinds

While the sector outlook contains pockets of strong growth, institutional investors must remain cognizant of the following systemic and idiosyncratic risks:

1. Domestic Installation Misses

• Risk: If the September decline in domestic installations (-53.8% YoY) reflects a deeper structural slowdown rather than a temporary fluctuation, full-year targets may be missed.
• Impact: Lower-than-expected domestic demand would exert downward pressure on module prices and utilization rates across the supply chain, compressing margins for manufacturers. Grid curtailment issues in key provinces could further dampen installer sentiment.

2. Supply Chain Price Volatility

• Risk: The PV industry is prone to cyclical oversupply. While polysilicon prices have stabilized, intense competition in cells and modules could reignite price wars.
• Impact: Rapid price declines erode inventory values for manufacturers and distributors. Conversely, sudden price spikes (due to raw material shortages) can stall project economics for developers. Margin compression is the primary financial risk here.

3. Geopolitical and Trade Policy Uncertainty

• Risk: The export sector, which is a key growth engine (as evidenced by the +46.8% module volume growth), faces significant headwinds from trade protectionism.
  • Europe: Potential anti-subsidy investigations or carbon border adjustment mechanisms (CBAM).
  • USA: Continued strict enforcement of UFLPA (Uyghur Forced Labor Prevention Act) and tariff barriers.
  • Emerging Markets: Potential local content requirements in India, Brazil, or other key growth regions.
• Impact: Sudden policy changes could block access to lucrative markets, force costly supply chain reconfigurations, or impose punitive tariffs, directly impacting the revenue and profitability of export-oriented firms like Sungrow, Jinko, and Trina.

4. Technology Iteration Risk

• Risk: The rapid transition from PERC to TOPCon and now to BC/HJT technologies carries execution risk.
• Impact: Companies that fail to keep pace with technological upgrades may face stranded assets and obsolete inventory. Capital expenditure requirements for new tech lines are high, potentially straining balance sheets for less capitalized players.
