Huayao PV HY490-N120BDD 480–500W N-Type TOPCon Bifacial Solar Panel
Model HY490-N120BDD | N-Type TOPCon | 120 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The Huayao PV HY490-N120BDD is a high-performance monocrystalline solar panel designed for strong output and dependable long-term operation. This bifacial module uses N-Type TOPCon technology to support excellent efficiency and stable energy generation across changing conditions. It delivers a rated maximum power of 490 Wp, with a 480 to 500 Wp power range and up to 23.09% module efficiency across the series. The panel is built with 120 half-cells and a positive power tolerance of 0 to +3%. Its 15-year product warranty and 30-year linear power warranty make it a practical choice for residential and commercial solar projects. The module also offers strong mechanical durability, low-light performance, and robust protection for demanding installations.
Key Benefits
High power output: The module reaches 490 Wp and scales up to 500 Wp in the series.
Excellent efficiency: Module efficiency reaches 22.63% on this model and 23.09% across the series.
Bifacial energy gain: The bifacial design can capture reflected light from the rear side for improved yield.
N-Type TOPCon technology: Advanced cell architecture supports better low-light behavior and long-term stability.
Reliable durability: The panel is tested for 5400 Pa snow load and 2400 Pa wind load resistance.
Positive tolerance: A 0 to +3% power tolerance helps ensure strong delivered performance.
How It Works
The HY490-N120BDD converts sunlight into electrical energy through monocrystalline N-Type TOPCon cells. The 120 half-cell format helps reduce internal resistance and connection loss. This improves current flow and supports higher output under real-world operating conditions. Because the module is bifacial, it can also absorb reflected light from behind the panel. That additional light can increase total energy harvest in suitable installations. The panel is designed to operate across a wide temperature range and maintain stable output in demanding climates. Its low temperature coefficients help reduce performance loss when module temperatures rise. The durable frame, thick glass, and IP68 junction box help protect the module over many years of service.
Half-cell electrical design: The 120 half-cell layout lowers resistive loss inside the module. It also improves current handling and supports more stable performance.
Bifacial light capture: The rear side can absorb reflected irradiance from the installation surface. This can raise total production in bright environments.
Temperature-controlled performance: The module uses low temperature coefficients to limit heat-related output decline. This helps maintain stronger energy yield during hot weather.
