Market Insights on China Bi-facial Solar Market• China's bifacial solar market has fundamentally transformed the global photovoltaic landscape, with the National Energy Administration reporting that the country installed 316.57 GW of new solar capacity in 2025, comprising 163.57 GW of utility-scale and 153 GW of distributed generation. Bifacial modules now represent over 80% of the market, a dramatic increase from zero a decade ago.• According to the research report, "China Bi-facial Solar Market Overview, 2031," published by Bonafide Research, the China Bi-facial Solar market is anticipated to grow at 15.83% CAGR from 2026 to 2031. The China Photovoltaic Industry Association confirms that bifacial module market share reached 67% in 2023 and is expected to reach 70% in 2024. The market's evolution has been propelled by the recognition that bifacial modules deliver of 5% to 15% in grass, sand, and snow environments, with greater contributions during morning and evening hours. • The Ministry of Industry and Information Technology reports that by the end of 2024, all major segments of the PV industry chain had surpassed 1,200 GW of production capacity. The industry produced over 620 GW of crystalline silicon modules in 2025, up 5.4% year-on-year. China's dominance extends across the entire value chain, with the International Energy Agency confirming that Chinese manufacturers hold more than 80% market share in all key solar production segments globally. • The market faces challenges including severe supply-demand imbalance, with 2025 global demand of only approximately 580 GW against domestic capacity exceeding 1,200 GW. Despite this oversupply, bifacial technology continues its rapid adoption trajectory, with major tenders from state-owned enterprises exclusively specifying N-type TOPCon bifacial double-glass modules.

The combination of massive scale, technological advancement, and supportive policies positions China as the undisputed global leader in bifacial solar manufacturing and deployment.Competitive Landscape of China Bi-facial Solar Market• LONGi Green Energy has established a strong position with its Hi-MO series, announcing in April 2025 the upgraded Hi-MO 9 module achieving 24.8% conversion efficiency and 80% bifaciality, representing a 10-percentage-point improvement over the previous generation. The company's Hi-MO X10 won the prestigious pv magazine Award 2025 for back contact bifacial innovation. • Tongwei Solar has achieved industry-leading TOPCon cell bifaciality of 94.3% and module bifaciality of 91.7%, certified by TÜV Rheinland. The company's 722 W TOPCon module, with 25.67% front-side efficiency and 24.21% rear-side efficiency, represents the cutting edge of commercial bifacial technology. • JinkoSolar's Feihu 3 modules have achieved 24.8% mass-production efficiency with 670 W power and up to 90% bifaciality. Trina Solar has advanced its i-TOPCon Ultra technology, achieving 85% bifaciality with large-format modules reaching 740 W mass-production power. The company holds proprietary i-TOPCon bifacial cell structures and processes. • Liansheng Photovoltaic launched two HJT modules at the 2025 China International Photovoltaic and Energy Storage Conference, with the Tianwangxing PRO achieving 95% bifaciality and 745 W+ mass-delivery power with 24%+ conversion efficiency. Entry barriers include massive capital requirements, with the industry already possessing 1,000 GW of advanced capacity (including 900 GW of TOPCon representing RMB 250 billion in investment). • The market has witnessed significant consolidation pressure, with 20 listed PV companies alone reporting net losses of RMB 55.5 billion in 2024.

Consumer behavior shows clear preference for TOPCon technology in utility-scale applications due to its superior bifaciality, low-irradiance performance, and low attenuation characteristics, making it particularly competitive in ground-mounted projects with high surface reflectivity. China Market Dynamics Driver: State-Owned Enterprise Procurement and Utility-Scale Project PipelineChina's bifacial solar market is driven by massive procurement from state-owned enterprises that exclusively specify N-type TOPCon bifacial modules. China National Energy Group's tenders consistently require N-type TOPCon bifacial double-glass modules at 640 Wp and above. The company's 513.53 MW procurement in December 2025 attracted bids from Tongwei and JinkoSolar at RMB 0.750-0.756 per watt. Huadian Corporation secured 3 GW of module procurement. China National Nuclear Corporation reached 22.88 GW of utility-scale PV capacity. This sustained demand from state-owned enterprises provides a stable and growing market for bifacial technology. Challenge: Severe Overcapacity and Price CompetitionChina's bifacial solar market confronts a severe supply-demand imbalance, with MIIT data showing that by end-2024, all main industry chain segments had exceeded 1,200 GW of production capacity.

Global demand for 2025 is only about 580 GW, meaning supply exceeds demand by more than double. This oversupply has directly triggered significant price volatility and intense competition. The industry's 1,000 GW of advanced capacity, representing RMB 250 billion in TOPCon investment alone, faces the risk of asset stranding. 2024 saw 20 listed PV companies report combined net losses of RMB 55.5 billion. Trend: Transition to Comprehensive Efficiency Metrics China's bifacial solar market is witnessing a critical trend toward comprehensive efficiency evaluation that considers both front and rear-side power generation. Industry experts advocate that the traditional front-side conversion efficiency metric no longer adequately reflects bifacial module performance, as bifacial modules now represent over 80% of the market. TOPCon 2.0 modules have achieved 85% bifaciality, 15% higher than leading BC products, delivering 0.4%-1.09% per-watt generation gain at 5%-30% ground reflectivity. The National Photovoltaic and Energy Storage Empirical Platform's 2025 annual report confirmed TOPCon modules achieved the highest power generation among all technology types.

This trend toward comprehensive efficiency metrics is reshaping technology selection and project economics. Segment AnalysisChina Bi-facial Solar Market by Type• Dual-glass bifacial modules have become the absolute standard in China's utility-scale market, with all major state-owned enterprise tenders exclusively specifying this architecture.
