Description
The Hyundai 640 watt monocystalline TOPCon bifacial solar panel delivers ultra-high power output, cutting-edge N-type performance, and proven long-term reliability for commercial, industrial, and utility-scale solar systems. Built with premium N-Type TOPCon monocrystalline technology and a 16-busbar, 156 half-cut bifacial cell architecture, this HiS-T640NJ module is engineered for high efficiency, reduced degradation, and exceptional durability. Its dual-glass construction enhances weather resistance and is certified to withstand 5400 Pa front load and 2400 Pa rear load, ensuring strong performance in harsh climates. Operating at an impressive 22.9% efficiency, this large-format module maximizes energy yield where every square foot matters.
With its high bifaciality rating (80 ± 5%), the Hyundai 640W TOPCon module can generate up to 25% additional rear-side power, boosting total output up to 800 watts under optimal ground-reflective conditions. This additional gain makes the HiS-T640NJ an exceptional choice for ground mounts, carports, and large-scale systems designed to capture maximum kWh production. Backed by Hyundai’s industry-leading 12-year product warranty and 30-year performance warranty (guaranteeing 87.4% output at year 30), this 640W panel combines high power, reliability, and long-term value for large solar installations. UL Certified, CEC approved. Order online or by PHONE 888-498-3331
