Product Description
Trina Solar Vertex N TSM-NEG19RC.20 is a high-performance N-type monocrystalline silicon bifacial photovoltaic module, designed to deliver superior power output, exceptional durability, and long-term reliability across a wide range of solar applications. As part of Trina Solar‘s renowned Vertex N series, this module leverages cutting-edge i-TOPCon (Tunnel Oxide Passivated Contact) cell technology and a robust dual-glass (glass-glass) construction to maximize energy generation while maintaining outstanding mechanical resilience.
Certified for deployment in even the harshest environments, this module is built to withstand extreme weather conditions, including salt spray, ammonia, sandstorms, high temperatures, and high humidity.
High Power Output & High Efficiency
Built on Trina Solar‘s pioneering 210 mm technology platform and proprietary i-TOPCon architecture, the TSM-NEG19RC.20 delivers up to 635 Wp maximum power with module efficiency reaching 23.5%. This high power density enables greater energy harvest per unit area, reducing the number of modules required for a given installation and lowering overall system costs.
Bifacial Dual-Glass Design
The bifacial glass-glass construction enables energy generation from both the front and rear sides of the module, delivering up to 20–30% additional power gain from the rear side depending on ground albedo (reflectivity). The dual-glass structure also provides superior protection against mechanical stress, moisture ingress, and environmental degradation, ensuring stable performance throughout the module‘s extended operational lifetime.
N Type i-TOPCon Technology
Trina Solar has been a pioneer in TOPCon technology since 2015, leading the industry with the first patents and the first commercialization of i-TOPCon cells in 2018. The N-type i-TOPCon cells in the TSM-NEG19RC.20 feature a quantum tunneling passivation contact structure, which delivers:
Low power degradation: ≤1% in the first year, followed by only 0.4% annual degradation thereafter.
Excellent temperature coefficient: -0.29 %/°C for Pmax, ensuring superior high-temperature performance.
Superior low-light and incident angle performance: Validated by third-party certifications.
FAQ
The bifacial design enables up to 10–20% additional rear-side energy gain under optimal conditions (e.g., high ground albedo from snow, light-colored gravel, or sand). With a bifaciality factor of 80%, the module effectively captures diffused and reflected sunlight from the rear side, maximizing total system energy yield without increasing the installed footprint.
Yes. The TSM-NEG19RC.20 is engineered for demanding environments:
Mechanical load capacity: Up to 5400 Pa positive load (snow) and 2400 Pa negative load (wind).
Operating temperature range: -40 °C to +85 °C.
Harsh environment resistance: Certified for salt mist (IEC 61701), ammonia corrosion (IEC 62716), sand, high temperature, and high humidity.
PID resistance: ensured through cell process and module material control.
Micro-crack minimization: Achieved through innovative non-destructive cutting and high-density packaging technologies.
Absolutely. The module is perfectly compatible with 1P (single-axis) tracker systems, particularly with TrinaTracker Vanguard 1P trackers to maximize racking length utilization. The low-voltage design enables higher string power, effectively reducing BOS (Balance of System) costs and LCOE (Levelized Cost of Energy) by approximately 1%–5%. This makes the module an excellent choice for utility-scale ground-mounted solar farms with tracking systems.
