Huayao PV HY485-N120BDD 480–500W N-Type TOPCon Bifacial Solar Panel
Model HY485-N120BDD | N-Type TOPCon | 120 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The Huayao PV HY485-N120BDD is a high-efficiency bifacial solar panel built with N-type TOPCon technology. It is designed for strong energy production, reliable long-term performance, and excellent low-light response. With a rated output of 485 Wp, this module suits residential and commercial solar projects that need dependable power density. The 120-cell half-cut layout helps reduce internal power loss and supports stable operation across changing temperatures. Its positive power tolerance and advanced cell design provide an added performance advantage for modern photovoltaic systems.
Key Benefits
High Power Output: This module delivers up to 485 Wp, with a broader power range reaching 500 Wp.
Excellent Efficiency: The panel achieves 22.4% efficiency, helping maximize usable roof space.
Bifacial Energy Gain: Bifacial construction allows rear-side light capture for improved overall generation.
N-Type TOPCon Technology: Advanced cell technology supports stronger performance and lower degradation over time.
Positive Power Tolerance: A 0 to +3% tolerance helps ensure output meets or exceeds the rated nameplate value.
Strong Durability: The module is built with an anodized aluminum frame, IP68 junction box, and 2.0 mm glass.
How It Works
This bifacial solar panel converts sunlight into electricity through N-type TOPCon cells arranged in a 120-cell half-cut format. The design improves electrical flow by reducing resistance and connection losses. Light striking the front side generates primary output, while reflected light from the rear side can also contribute to power production. That makes the module especially effective in installations with light-colored surfaces or reflective ground conditions. The low temperature coefficient helps maintain performance in hot environments. Together, these features support efficient, stable solar generation across daily operating conditions.
Photon Conversion: Sunlight reaches the N-type TOPCon cells and is converted into direct current electricity. The 120 half-cells help reduce internal losses and improve current handling.
Bifacial Absorption: The rear side can capture reflected light and convert it into extra output. This can improve energy yield in suitable installation environments.
Thermal Stability: The module is designed to retain output under higher temperatures. Its temperature coefficients help limit performance loss during hot weather.
