Huayao PV HY480-N120BDD 480W N-Type TOPCon Bifacial Solar Panel
Model HY480-N120BDD | N-Type TOPCon | 120-Cell Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The Huayao PV HY480-N120BDD is a high-efficiency monocrystalline solar panel built with advanced N-Type TOPCon bifacial technology. It is designed for strong energy yield, reliable long-term performance, and stable operation in demanding environments. With a rated output of 480 Wp and module efficiency of 22.17%, it offers a strong balance of power and compact dimensions. The panel uses 120 cells and a positive power tolerance of 0 to +3%. Its 15-year product warranty and 30-year linear power warranty support long service life and dependable project planning.
Key Benefits
High Power Output: Delivers 480 Wp for efficient performance in residential and commercial solar projects.
Excellent Efficiency: Reaches 22.17% module efficiency, helping maximize generation from limited roof space.
Bifacial Energy Gain: Bifacial construction supports additional rear-side power generation under suitable installation conditions.
Strong Durability: Anodized aluminum framing, IP68 junction box protection, and robust build quality support reliable operation.
Long Warranty Coverage: Includes a 15-year product warranty and a 30-year linear power warranty for added confidence.
How It Works
The HY480-N120BDD converts sunlight into electricity through N-Type TOPCon cells arranged in a 120-cell half-cut design. This architecture improves electrical flow and reduces connection losses. The bifacial module can capture light from the rear side as well, which may increase total energy yield in reflective environments. Its positive power tolerance supports dependable output at installation. The low temperature coefficient helps maintain performance as module temperatures rise during operation.
N-Type TOPCon Cell Conversion: The cells absorb sunlight and convert it into direct current electricity. TOPCon technology supports high efficiency and stable power production.
Half-Cell Power Flow: Half-cut cells lower resistance losses across the module. This helps improve output and reduces performance loss from heat.
Bifacial Rear-Side Capture: The panel can use reflected light from behind the module. This is especially useful on bright roofs and ground-mounted systems.
