Huayao PV HY640-N120CDD 630–650W N-Type TOPCon Bifacial Solar Panel
Model HY640-N120CDD | N-Type TOPCon | 120 Cells | Bifacial | 1500V System Voltage
Product Overview
The Huayao PV HY640-N120CDD is a high-output bifacial solar panel built for demanding residential and commercial projects. It uses N-Type TOPCon technology to support strong energy yield and improved low-light performance. This monocrystalline module delivers up to 640 Wp of power, with a power range from 630 to 650 Wp. Its 120-cell layout helps balance compact design with strong electrical performance. The panel also offers a 22.61% efficiency rating, making it a strong choice for space-conscious installations. A 15-year product warranty and 30-year power warranty add long-term confidence.
Key Benefits
High Power Output: The module reaches 640 Wp and supports a 630 to 650 Wp range.
Excellent Efficiency: It delivers 22.61% efficiency for stronger energy production in limited space.
N-Type TOPCon Technology: Advanced cell technology improves performance, stability, and low-light response.
Bifacial Design: Rear-side generation can improve total system yield in suitable mounting conditions.
Long Warranty Protection: A 15-year product warranty and 30-year power warranty support long-term value.
Durable Construction: The anodized aluminum frame, IP68 junction box, and strong glass support reliability.
How It Works
The HY640-N120CDD converts sunlight into electricity through N-Type monocrystalline cells arranged in a 120-cell design. Its TOPCon structure helps reduce energy loss and improve conversion efficiency. The bifacial format can capture light from both the front and rear sides of the module. That makes the panel especially useful where reflected light is available. The half-cell architecture also helps reduce resistance losses and supports better thermal behavior. Together, these features help the module produce stable power across a wide range of operating conditions.
N-Type Cell Conversion: Sunlight is absorbed by N-Type monocrystalline cells and converted into usable DC power. This cell type is known for strong efficiency and durability.
Bifacial Energy Capture: Light reaching the rear surface can generate additional output. This is useful on reflective rooftops and open ground mounts.
Thermal and Electrical Stability: Low temperature coefficients help the panel maintain better output in hot conditions. The 1500V maximum system voltage supports modern solar system designs.
