The Vertex S+ platform is optimized for high-density rooftop installations where maximizing output per square foot is essential. Its bifacial capability increases total system generation by capturing reflected sunlight from the rear side of the panel.
Advanced Dual-Glass Construction
The dual-glass architecture uses reinforced 1.6 mm tempered glass on both the front and rear sides of the module. This provides:
✔️ Improved fire resistance
✔️ Enhanced moisture protection
✔️ Reduced microcracking risk
✔️ Increased long-term structural stability
✔️ Superior weather durability
This design makes the module particularly suitable for coastal, snowy, high-wind, and high-humidity environments.
N-Type i-TOPCon Technology
Trina’s N-Type i-TOPCon technology improves module efficiency and minimizes long-term degradation compared to traditional P-Type modules.
Key Benefits:
✔️ Better low-light performance
✔️ Improved temperature coefficient
✔️ Lower degradation over time
✔️ Higher lifetime energy yield
✔️ Enhanced reliability in hot climates
The low 0.4% annual degradation rate helps maintain strong energy production throughout the system lifespan.
