DualMax Pro OJ Series | 156 Half-Cut Bifacial Mono PERC Cells | 545.7W PTC | 12/25 Warranty
The Hyundai HiS-S585OJ is a high-output commercial and utility-scale bifacial solar module from HD Hyundai Energy Solutions' DualMax Pro OJ Series. Delivering 585W with 21.2% module efficiency through 156 half-cut bifacial monocrystalline PERC cells in a 6×26 configuration, this large-format panel is engineered for maximum energy yield per racking position in ground-mount, carport, and large commercial rooftop applications. The transparent backsheet enables meaningful rear-side energy capture from reflected and diffused light, while the 3.2mm full-tempered front glass with anti-reflective coating provides industry-leading 50mm hailstone resistance certified to IEC 61215:2016 by kiwa PVEL—a critical advantage in hail-prone regions. With a verified 545.7W PTC rating demonstrating strong real-world performance and UL Fire Type 1 certification for building-code compliance, this panel delivers robust bankability for project financing. Extended 1,400mm PV wire leads with genuine Stäubli MC4 connectors simplify wiring in commercial racking systems, and the 35mm clear anodized aluminum frame with 8 mounting holes provides versatile, secure installation options. Rated for 1500V DC systems with 5,400 Pa front / 3,000 Pa rear load ratings, and backed by HD Hyundai's 12-year product warranty and 25-year linear performance guarantee. Manufactured by HD Hyundai Energy Solutions Co., Ltd., Korea.
585W High-Density Output: At 585W from a 156-cell large-format design, this panel maximizes watts-per-racking-position and reduces balance-of-system costs in commercial and utility installations. Fewer panels mean fewer racking components, fewer wiring connections, and lower labor costs per installed watt—driving down total project LCOE.
Bifacial Mono PERC with Transparent Backsheet: Bifacial monocrystalline PERC cells paired with a transparent backsheet capture reflected and diffused light from the rear side, delivering meaningful additional energy generation—particularly effective over high-albedo surfaces like white roofing membranes, concrete, gravel, or snow in ground-mount and carport installations.
50mm Hailstone Resistance: The 3.2mm full-tempered front glass with anti-reflective coating is certified for 50mm hailstone impact resistance per IEC 61215:2016 testing by kiwa PVEL—significantly exceeding the standard 25mm requirement and providing critical protection for installations in hail-prone regions across the central United States and beyond.
PTC Verified Performance: The 545.7W PTC rating (93.3% PTC-to-STC ratio) validates strong real-world performance under actual operating conditions, giving system designers and project financiers confidence in energy yield projections and financial modeling.
UL Fire Type 1 Certified: Fire Type 1 certification ensures compliance with the most stringent building codes for rooftop installations, enabling permitting across all jurisdictions that require Type 1 fire classification—essential for commercial roof-mount projects.
Extended 1,400mm Cable Leads: Long 1,400mm (~55.2") PV wire leads with genuine Stäubli MC4 connectors simplify wiring in commercial and utility racking systems, reducing the need for extension cables and minimizing connection points in the string—improving both reliability and installation speed.
HD Hyundai — Global Tier-1 Manufacturer: Manufactured by HD Hyundai Energy Solutions Co., Ltd. in Korea with ISO 9001, ISO 14001, and ISO 45001 certifications, plus UL61730 and IEC 61215 compliance. Backed by the financial strength of the HD Hyundai conglomerate, ensuring long-term bankability, warranty reliability, and project financing confidence.
This solar panel converts sunlight into electricity through its bifacial monocrystalline PERC cells, utilizing Passivated Emitter and Rear Contact technology on both sides of each cell to capture direct, reflected, and diffused light for maximum energy generation.
Bifacial PERC Cells: Each cell features rear-side passivation that enables light absorption from both front and back surfaces, capturing reflected light from roofing materials, ground surfaces, snow, and surrounding structures. In optimal bifacial installations over high-albedo surfaces, rear-side energy gains of 5–25% above nameplate rating are achievable, with the 585W front output potentially reaching up to 744W equivalent total generation.
Half-Cut Cell Architecture: 156 half-cut cells arranged in a 6×26 configuration reduce internal resistive losses by splitting current paths, improving both overall efficiency and shade tolerance. The split-string design allows unshaded portions of the panel to continue generating when partial shading occurs from structural elements, soiling, or adjacent rows.
Transparent Backsheet Design: The highly resistant and weatherproof transparent backsheet allows light to pass through to the rear side of the bifacial cells, enabling rear-side energy generation without the added weight and cost of a full glass-glass construction. This delivers bifacial performance advantages while maintaining a lighter module weight for easier handling and broader racking compatibility.
