SEG Solar 440w Domestic Content Solar Panel SEG-440-BTD-BG-T3

The SEG Solar 440W 108 Half-Cell N-Type Black Bifacial Solar Panel (SEG-440-BTD-BG T3) is a high-performance, all-black module from SEG Solar’s Yukon N series, engineered for superior efficiency, durability, and aesthetic appeal in residential and commercial installations. As a U.S.-based manufacturer headquartered in Houston, Texas, SEG Solar emphasizes reliable, cost-effective PV solutions with strong domestic content compliance (indicated by the T3 designation for FEOC and U.S. incentives eligibility).

Key Features and Benefits

• Advanced N-Type TOPCon Technology: Utilizes N-type monocrystalline half-cut cells (108 cells, 182 x 91 mm size) for excellent low-light performance, reduced degradation, and a superior temperature coefficient, delivering more energy over time compared to traditional P-type panels.
• Bifacial Design: Captures sunlight on both front and rear sides, with bifaciality around 80±10%, boosting overall energy yield by up to 20-30% in reflective environments (e.g., light-colored roofs, ground mounts, or snow).
• High Efficiency and Power Output: Rated at 440W (front-side STC) with module efficiency up to 22.53%, optimizing space-constrained rooftops while maximizing production.
• All-Black Aesthetic: Sleek black anodized aluminum frame, black backsheet (double-glass construction with 2.0 mm AR-coated semi-tempered glass), and black cells create a premium, uniform look ideal for modern homes.
• Robust Durability: Withstands high mechanical loads (front: 5400 Pa / ~113 psf; rear: 2400 Pa / ~50 psf), plus resistance to PID, salt mist, ammonia, dust, sand, and hail. IP68-rated junction box with MC4 connectors ensures long-term reliability.
• Low Degradation and Strong Warranties: Features low annual degradation (first-year ~0.4%, then linear), backed by a 30-year product/material workmanship warranty and 30-year linear power output warranty (guaranteeing ~87.4% output at year 30).
• Domestic Content Ready: Built with U.S. manufacturing elements, qualifying for incentives under relevant domestic content rules.
