31 Philadelphia Solar Nexus 580W N-Type Bifacial Half-Cell module delivers industry-leading efficiency and long-term reliability for commercial, off-grid, and utility-scale solar installations.

Key Features

• Bifacial Power Boost Rear-side power generation increases total output by 5–25%, significantly reducing your levelized cost of energy.
• N-Type Half-Cell Design 144 half-cells with 16 busbars deliver superior temperature coefficients and reduced partial shading losses for maximum yield.
• Exceptional Anti-PID Performance Optimized mass-production processes and strict material controls ensure long-term protection against potential-induced degradation.
• High Mechanical Load Tolerance Engineered to withstand 5400 Pa on the front and 2400 Pa on the back for resilience in demanding weather conditions.
• 30-Year Linear Power Warranty Only -0.4% annual degradation guarantees 94.6% output at year 12 and 87.4% at year 30.

This pallet of 36 modules delivers up to 21,600W of combined peak power, making it an efficient solution for rooftop commercial systems or ground-mount solar installations. Each panel carries a 12-year product warranty backed by Philadelphia Solar's certified manufacturing standards.

The PS-MNB144(HCBF) is certified under UL 61215, UL 61730, IEC 61215, IEC 61730, and CSA C22.2#61730:2019, meeting rigorous international safety and performance benchmarks. Additional certifications include IEC 61701 Salt Mist, IEC 62716 Ammonia, and IEC 60068 Dust and Sand Resistance.

Built with 3.2mm tempered AR-coated glass, a transparent backsheet, and an anodized aluminum frame, this module is engineered for durability across the harshest environmental conditions. The IP68-rated junction box with original MC4 connectors ensures a secure, weatherproof electrical connection.
