Executive Summary

Trina Solar Co., Ltd. (688599.SH), a global leader in photovoltaic (PV) smart energy solutions, released its semi-annual report for the first half of 2025 (1H25). The results reflect the broader challenges facing the PV industry, characterized by severe supply-demand imbalances and intensified market competition. In 1H25, the company reported total operating revenue of RMB 31.06 billion, a year-on-year (YoY) decline of 27.7%, and a net profit attributable to shareholders of the parent company of -RMB 2.92 billion, representing a significant YoY decline of 654.5%. This performance was primarily driven by the continuous downward trajectory of module prices, which compressed margins across the core business.

Despite the headwinds in the traditional module segment, Trina Solar’s diversified business strategy is beginning to show defensive characteristics. The energy storage sector, in particular, emerged as a bright spot, with shipments holding steady at approximately 1.7 GWh. Leveraging its "Trina Cell" technology platform and the Elementa series large-capacity storage systems, the company aims to achieve annual shipments exceeding 8 GWh in 2025. We anticipate that the energy storage segment will experience simultaneous growth in volume and profitability throughout the year, supported by an increasing proportion of overseas orders and economies of scale.

Technologically, Trina Solar continues to lead the industry. The company recently set world records for the efficiency of 210mm half-cut industrial-sized perovskite/crystalline silicon tandem solar cells, achieving efficiencies of 31.1% and 32.2%. Furthermore, it became the first PV enterprise globally to break the 30% efficiency barrier for tandem modules in a laboratory setting (30.6%). These advancements underscore the company’s commitment to R&D and its ability to maintain a competitive edge through technological innovation.

Looking ahead, we expect the PV industry to gradually emerge from the current price war as anti-involution measures take effect and supply-side optimization accelerates. While short-term earnings remain under pressure, Trina Solar’s robust balance sheet, diversified product portfolio (modules, trackers, distributed systems, and storage), and global delivery capabilities position it well for the eventual industry recovery.

We maintain our "Recommend" rating for Trina Solar. We forecast the company’s net profits for 2025-2027 to be -RMB 3.97 billion, RMB 0.38 billion, and RMB 2.14 billion, respectively. The current stock price implies P/E ratios of -9x, 94x, and 17x for the respective years. Investors should monitor the pace of industry consolidation, raw material price fluctuations, and the execution of overseas expansion strategies.

Key Takeaways

1. Financial Performance: Revenue and Profitability Decline Amidst Industry Cycle

The financial results for 1H25 highlight the severity of the current downturn in the global PV market.

• Revenue Contraction: Total operating revenue stood at RMB 31.06 billion in 1H25, down 27.7% YoY. This decline is consistent with the broader industry trend where shipment volumes have remained relatively stable or grown slightly, but average selling prices (ASPs) have dropped significantly due to oversupply.
• Net Loss: The company recorded a net loss attributable to shareholders of RMB 2.92 billion, a drastic turnaround from the profitable periods of previous years. The 654.5% YoY decline in net profit underscores the impact of margin compression.
• Historical Context: Comparing with full-year data, the trend of declining profitability started in 2024, where the company already reported a net loss of RMB 3.44 billion. The 1H25 results suggest that the bottoming-out process is still ongoing, with further pressures evident in the first half of 2025.

Note: 1H2024 figures are derived based on the YoY change percentages and 1H2025 actuals provided in the report context.

2. Operational Highlights: Mixed Performance Across Business Segments

Trina Solar’s operational data reveals a divergence in performance across its various business units. While the core module business faces volume and price pressure, ancillary businesses like trackers and storage show resilience.

A. Photovoltaic Modules: Volume Stable, Price Depressed

• Shipments: In 1H25, Trina Solar achieved module shipments of over 32 GW. This figure is relatively stable compared to the 34 GW shipped in the same period last year. The stability in volume demonstrates the company’s strong market presence and ability to retain customers despite adverse market conditions.
• Pricing Pressure: The primary driver for the revenue and profit decline was the continuous drop in module prices. The industry-wide oversupply has led to aggressive pricing strategies, eroding gross margins. As the report notes, the industry is grappling with "involution" (intense, often irrational competition), which has pushed prices below the cost line for many manufacturers.

B. Distributed Systems: Significant Contraction

• Sales Volume: Sales of distributed systems amounted to approximately 1.5 GW in 1H25, representing a sharp 53% decline YoY.
• Analysis: This significant drop may be attributed to policy changes in key domestic markets, saturation in certain residential/commercial segments, or a strategic shift by the company to prioritize higher-margin or more scalable utility-scale projects. It also reflects the broader slowdown in downstream installation demand in specific regions due to grid connection bottlenecks or financing costs.

C. Trackers (Mounting Systems): Moderate Growth

• Shipments: Tracker shipments reached approximately 3.5 GW, a 9% increase YoY.
• Significance: The growth in tracker shipments indicates a successful penetration in the utility-scale market, particularly in regions where tracking systems are becoming standard for maximizing energy yield. This segment provides a complementary revenue stream to the module business and benefits from the global trend towards higher-efficiency plant designs.

D. Energy Storage: The Strategic Growth Engine

• Shipments: Energy storage system shipments were approximately 1.7 GWh in 1H25, remaining flat compared to the previous year. While volume did not grow explosively in H1, the segment is poised for acceleration in H2 and beyond.
• Market Context: The global battery energy storage system (BESS) market is experiencing rapid growth, driven by the acceleration of energy transition and the need for grid stability. Global BESS shipments are expected to grow by over 50% YoY in 2025.

5. Industry Outlook: Navigating the "Anti-Involution" Phase

The report highlights a critical thematic shift in the Chinese PV industry: the move towards "Anti-Involution" (curbing irrational competition).

• Supply-Side Reform: Regulatory bodies and industry associations are increasingly advocating for supply-side optimization. This includes raising technical standards, limiting low-quality capacity expansion, and encouraging mergers and acquisitions.
• Price Stabilization: As weaker players exit the market and capacity utilization rates adjust, the severe price war is expected to subside. The report suggests that the PV industry is likely to emerge from the current price dilemma, leading to a gradual repair of profitability.
• Timeline: While the exact timing of the turnaround is uncertain, the deepening of "anti-involution" measures suggests that the worst of the price declines may be behind us. However, a full recovery in margins will likely take time, extending into 2026 and 2027.

Risks / Headwinds

Investors should carefully consider the following risks, which could materially impact Trina Solar’s financial performance and stock price:

1. Overseas Market Expansion Risks

• Trade Barriers: The global PV market is increasingly fragmented by trade policies. Tariffs, anti-dumping duties, and local content requirements in key markets such as the United States (UFLPA, IRA provisions), Europe (Carbon Border Adjustment Mechanism), and India (ALMM list) pose significant challenges.
• Geopolitical Tensions: Escalating geopolitical tensions could lead to stricter export controls or bans, limiting Trina Solar’s access to high-margin markets.
• Execution Risk: Failure to effectively navigate these regulatory landscapes or establish local manufacturing partnerships could result in lost market share and reduced revenue potential.

2. Raw Material Price Volatility

• Polysilicon and Wafer Prices: While current low prices benefit module affordability, extreme volatility can disrupt supply chains and inventory valuation. A sudden spike in polysilicon prices could squeeze margins if module prices cannot be adjusted upwards quickly enough.
• Other Materials: Prices of silver (used in pastes), aluminum (frames), and glass also fluctuate. In a low-margin environment, even small increases in input costs can significantly impact net profitability.

3. Downstream Demand Fluctuations

• Interest Rates: High interest rates in major markets (e.g., US, Europe) increase the cost of capital for PV and storage projects, potentially delaying or canceling installations.
• Grid Connection Bottlenecks: In many regions, grid infrastructure has not kept pace with renewable energy deployment. Congestion and curtailment issues can dampen investor sentiment and slow down new project approvals.
• Policy Uncertainty: Changes in subsidy schemes, feed-in tariffs, or renewable energy targets in key countries can lead to abrupt shifts in demand.

4. Technology Iteration and Obsolescence

3. Financial Forecast and Assumptions

Our forecasts for 2025-2027 are based on the following key assumptions:

• Revenue Recovery: We project revenue to decline by 16.36% in 2025 due to lower average selling prices, followed by a recovery of 13.84% in 2026 and 13.28% in 2027. This recovery is driven by:

  • Stabilization of module prices as supply tightens.
  • Significant contribution from the energy storage business (targeting >8 GWh in 2025 and further growth in subsequent years).
  • Growth in tracker and distributed system sales as market conditions improve.

• Margin Improvement:

  • 2025: Gross margins remain under pressure (estimated ~10.29%) as the company clears inventory and competes aggressively. Net loss is expected to widen slightly to -RMB 3.97 billion due to asset impairments and continued low margins.
  • 2026-2027: As the industry stabilizes and the high-margin storage business scales, gross margins are projected to improve to 15.46% in 2026 and 16.37% in 2027. This leads to a return to profitability in 2026 (Net Profit: RMB 0.38 billion) and strong profit growth in 2027 (Net Profit: RMB 2.14 billion).

• Expense Control: We assume the company will maintain strict control over operating expenses (SG&A) while continuing to invest in R&D. The ratio of R&D expense to revenue is expected to remain stable or increase slightly to support technological leadership.

• Balance Sheet Management: The company is expected to manage its debt levels carefully, with a focus on optimizing the debt structure (shifting from short-term to long-term where possible) and improving working capital efficiency.

4. Strategic Recommendations for Investors

• For Long-Term Investors: Trina Solar represents a compelling opportunity to buy into a leading player at a cyclical trough. The current losses are largely transient, driven by industry-wide pricing anomalies rather than structural flaws in the company’s business model. The long-term thesis of global energy transition remains intact, and Trina is well-positioned to benefit from the eventual normalization of margins.
• For Tactical Traders: Monitor quarterly shipment data, particularly for the energy storage segment, and any signs of module price stabilization. Positive catalysts could include announcements of large overseas storage contracts, further efficiency records, or policy support for domestic PV consumption.
• Key Metrics to Watch:
  • Storage Shipment Volume: Progress towards the 8 GWh annual target.
  • Module ASP Trends: Signs of price floor establishment.
  • Gross Margin Trajectory: Quarterly improvement in blended margins.
  • Cash Flow: Operating cash flow generation to ensure liquidity during the downturn.

5. Conclusion

Trina Solar is navigating one of the most challenging periods in the history of the PV industry. The 1H25 results, marked by a significant decline in revenue and a net loss, are a reflection of these systemic headwinds. However, beneath the surface, the company is strengthening its strategic position. The robust performance of its tracker business, the promising growth trajectory of its energy storage segment, and its unparalleled technological achievements in tandem cells provide a solid foundation for future growth.

We believe that the market has overly penalized the stock for short-term earnings weakness, overlooking the long-term value creation potential of its diversified ecosystem. As the industry undergoes supply-side clearing and demand recovers, Trina Solar is well-equipped to lead the next phase of growth. Therefore, we maintain our Recommend rating, advising investors to look through the current volatility and focus on the company’s structural advantages and the impending industry turnaround.

Appendix: Detailed Financial Analysis

Income Statement Analysis

• Revenue Trend: The sharp decline in 2024 and 2025E is primarily price-driven. The recovery in 2026-2027 assumes volume growth and price stabilization.
• Margin Dynamics: Gross margins collapsed in 2024 due to the price war. The slight improvement in 2025E reflects cost reduction efforts and a higher mix of storage/tracker sales. The significant jump in 2026-2027 assumes a normalized industry environment where pricing power returns.
• Expense Rigidity: Administrative and R&D expenses remain relatively sticky, contributing to the operating loss in 2025. However, as revenue grows in 2026-2027, operating leverage will kick in, boosting net margins.

Balance Sheet Analysis

• Asset Structure: Total assets are projected to decrease in 2025 due to inventory drawdown and potential asset impairments.
• Liquidity: The current and quick ratios are declining, indicating tighter liquidity conditions. This is a concern and highlights the importance of managing working capital efficiently. The company may need to rely on short-term borrowing to bridge gaps, as seen in the increase in short-term borrowings in the forecast.
• Leverage: The asset-liability ratio remains high (around 73-74%). While manageable for a capital-intensive industry, it limits financial flexibility. Deleveraging will be a key focus once profitability returns.

Cash Flow Analysis

• Operating Cash Flow: Despite net losses, operating cash flow remains positive, though declining. This is supported by depreciation and amortization add-backs and working capital management. However, the trend is downward, reflecting the cash burn associated with lower margins.
• Investing Cash Flow: Capital expenditure (CapEx) is significantly reduced in the forecast period (from ~12-18 billion in prior years to ~3.8 billion). This prudent reduction in CapEx helps preserve cash during the downturn.
• Financing Cash Flow: The company is actively managing its debt, with net repayments expected in 2025 and 2027. This deleveraging effort is crucial for long-term financial health.
