TNC 3.0推出 通威为光储协同时代提供技术范本

Core Viewpoint - The article discusses the evolving landscape of the photovoltaic (PV) industry, emphasizing the importance of integrating energy storage with solar power systems to enhance project value and long-term returns. The introduction of Tongwei's TNC 3.0 series solar modules is highlighted as a response to market demands for higher efficiency and reliability in energy generation [2][4][13]. Group 1: Industry Trends - By 2025, China's cumulative photovoltaic installed capacity is expected to reach 315 GW, with new energy storage installations growing by 85% year-on-year to 144.7 GW [2]. - The era of merely pursuing installation scale is ending; future success will depend on the effective integration of photovoltaic systems with energy storage to achieve greater system benefits [2]. - The industry consensus is shifting towards the necessity of energy storage for project value enhancement and the selection of high-quality, adaptable solar modules for securing long-term returns [2]. Group 2: Tongwei TNC 3.0 Module Features - The TNC 3.0 series features a maximum power output of 770W and an efficiency of 24.8%, supported by a comprehensive reliability solution that includes high power output, high bifaciality, and improved performance in high-temperature and low-light conditions [4][6]. - The TNC 3.0 modules utilize a 360° passivated cell technology, achieving over 26.3% efficiency, which enhances energy output and reduces losses [6]. - The design includes a four-slice structure that minimizes micro-damage and optimizes electrical performance, resulting in a temperature coefficient of -0.26%/°C, ensuring stable power output even in high-temperature conditions [6][11]. Group 3: Performance Enhancements - The TNC 3.0 modules demonstrate significant advantages in energy generation across various climates, with performance improvements of 1.23% to 1.90% compared to conventional half-cell TOPCon modules [6]. - The bifaciality of the TNC 3.0 modules reaches 85±5%, enhancing energy capture in reflective environments such as sandy or snowy areas, which is crucial for maximizing overall system efficiency [8][9]. - The modules are designed to maintain high power output even under low light conditions, addressing the challenge of energy generation during peak pricing periods [10]. Group 4: Reliability and Long-term Performance - The TNC 3.0 modules incorporate a dual-channel circuit design that mitigates the impact of shading or faults, thereby reducing energy loss and enhancing performance under non-ideal conditions [11]. - The four-slice design distributes stress more evenly, reducing the risk of micro-cracks by 50% compared to traditional half-cell structures, which enhances long-term reliability [11]. - The modules achieve a first-year degradation of ≤1% and a linear annual degradation of ≤0.35%, ensuring stable output and meeting investor demands for predictable returns [11]. Group 5: Future Outlook - The TNC 3.0 series is positioned to play a critical role in the integration of photovoltaic and energy storage systems, responding to the industry's need for high power output, comprehensive generation capabilities, and reliability [13]. - The launch of TNC 3.0 reflects Tongwei's ongoing technological advancements and provides a model for the industry as it navigates the transition into a "value deep water zone" [13].
