Model HiN-T640NJ | 156 Half-Cut N-Type TOPCon Cells | Bifacial Glass-Glass | 605.6W PTC | 30-Year Warranty
Maximize your project's energy output with the HD Hyundai HiN-T640NJ, a premium bifacial module featuring advanced N-Type TOPCon cell technology engineered for commercial, utility-scale, and carport applications. This 640W panel utilizes 156 half-cut monocrystalline TOPCon cells with 16-busbar design to deliver an exceptional 22.90% module efficiency and 80% bifaciality factor for significant rear-side energy gains. The robust glass-glass construction with a 35mm silver anodized aluminum frame and 2.0mm semi-tempered solar glass on both surfaces ensures outstanding mechanical resilience rated to 5,400 Pa front load. Extended 1,400mm output cables on both positive and negative leads provide maximum installation flexibility for commercial racking systems. With a verified 605.6W PTC rating demonstrating real-world performance, the HiN-T640NJ is purpose-built for demanding large-scale installations. Rated for 1500V DC systems and backed by a 12-year product warranty and 30-year linear performance guarantee.
N-Type TOPCon Cell Technology: Advanced Tunnel Oxide Passivated Contact (TOPCon) cells deliver industry-leading 22.90% module efficiency with lower degradation rates, superior low-light performance, and excellent temperature coefficients compared to conventional PERC technology.
High Bifaciality (80%): Dual-glass bifacial design with 80% bifaciality factor captures reflected and diffused light from rear surfaces, boosting total energy generation by up to 25–30% in optimal ground-mount and carport installations with high-albedo surfaces.
Glass-Glass Durability: 2.0mm semi-tempered solar glass on both front and rear surfaces provides superior mechanical strength with 5,400 Pa front load and 2,400 Pa rear load ratings, enhanced PID resistance, and long-term protection against environmental degradation.
Carport Compatible Design: Engineered specifically for compatibility with carport applications, combining high power density with the structural integrity and aesthetic requirements of covered parking installations.
PTC Rated Performance: 605.6W PTC rating demonstrates real-world efficiency under actual operating conditions, providing reliable performance expectations for system designers and EPC contractors.
Extended Output Cables: 1,400mm (~55.1 in) PV cables on both positive and negative leads provide greater reach and flexibility for commercial racking systems, reducing the need for cable extensions and simplifying installation.
Comprehensive Environmental Testing: Certified for salt mist corrosion (IEC 61701), ammonia corrosion (IEC 62716), PID resistance (IEC 62804), and sand/dust durability (IEC 60068-2-68)—built to perform in the harshest environments.
This solar panel harnesses sunlight through its advanced N-type TOPCon monocrystalline silicon cells, utilizing tunnel oxide passivation to transform solar energy into electricity with exceptional efficiency. The bifacial glass-glass design captures both direct sunlight and reflected light from surrounding surfaces for maximum energy generation.
TOPCon Cell Architecture: Tunnel Oxide Passivated Contact technology creates an ultra-thin oxide layer on the cell rear, dramatically reducing recombination losses and enabling higher open-circuit voltages for superior energy conversion efficiency.
Half-Cut Cell Design: 156 half-cut cells arranged in a 6×26 configuration reduce internal resistance and power loss, improving shading tolerance and delivering higher energy yields in real-world conditions with partial shading.
Bifacial Glass-Glass Construction: Semi-tempered solar glass on both front and rear surfaces enables rear-side energy capture from reflected and diffused light while providing exceptional mechanical protection and long-term durability across a 30+ year service life.
