SEG Solar SEG-440-BTD-BG 440w Solar Module

SEG Solar SEG-440-BTD-BG 44w Solar Module

The SEG Solar 440W 108 Half-Cell 1500V N-Type Black Bifacial Solar Panel (SEG-440-BTD-BG) is a high-efficiency, all-black bifacial module from SEG Solar’s Yukon N series. Headquartered in Houston, Texas, SEG Solar is a U.S.-based vertically integrated manufacturer (founded in 2016) focused on reliable, cost-effective solar solutions for residential, commercial, and utility markets. This panel leverages advanced N-type TOPCon (Tunnel Oxide Passivated Contact) technology with 182mm half-cut cells, delivering strong performance, low degradation, and excellent bifacial energy gain.

Key Features and Benefits

• High Efficiency and Power Output: Rated at 440W with up to 22.53% module efficiency (front side), it maximizes energy production in space-limited installations. The bifacial design captures reflected light from the rear, potentially boosting total output by 10-30% depending on surface albedo and mounting (bifaciality ~80±10%).
• Sleek All-Black Aesthetic: Full-black frame and backsheet (BTD-BG: Black on Black) provide a premium, uniform appearance with minimal visible busbars, ideal for residential rooftops where curb appeal matters.
• Advanced N-Type Technology:
  • Near-zero LID/LeTID (Light-Induced Degradation / Light and Elevated Temperature Induced Degradation) for better long-term stability.
  • Superior temperature coefficient for reduced power loss in high-heat conditions.
  • Excellent low-light and low-irradiance performance.
  • Super multi-busbar (MBB) design minimizes shading losses and improves current collection.
• Bifacial Gain and Durability: Higher bifaciality than traditional PERC modules, plus robust construction with reinforced glass and frame for superior load capacity (front: 5400 Pa / back: 2400 Pa).
• Reliable in Harsh Environments: Certified for PID resistance, salt mist, ammonia, dust/sand, and hailstone, with UL and IEC compliance.

This panel excels for residential and commercial applications seeking high efficiency, aesthetic integration, and enhanced energy yield from bifacial technology—especially on reflective surfaces like white roofs, ground mounts, or elevated racking. It offers better temperature performance and lower degradation compared to many PERC-based panels, making it a solid choice for maximizing lifetime production.
