Hanersun 625W Bifacial N-Type TOPCon Solar Panel

Hanersun 625W Bifacial Solar Panel (HN21RN-66HT625W)

Overview of the Hanersun 625W Bifacial Solar Panel

The Hanersun 625W bifacial solar panel is a high-efficiency N-type TOPCon photovoltaic module designed for large residential, commercial, and utility-scale solar installations. Using advanced N-type cell technology and bifacial power generation, this panel delivers high energy yield, excellent temperature performance, and long-term reliability in demanding environments.

What the Hanersun 625W Panel Is Designed to Do

This solar panel converts sunlight into DC electrical power and is designed to:

• Deliver high power output per module to reduce balance-of-system costs
• Increase total energy production through bifacial rear-side generation
• Maintain strong performance in high-temperature conditions
• Provide long service life with low annual degradation

What This Panel Is Not

This product is a photovoltaic module only.

• It is not an inverter and does not output AC power
• It does not store electrical energy
• It does not include mounting hardware, cabling, or protection devices

Cell Technology and Module Design

The Hanersun 625W panel uses advanced N-type TOPCon monocrystalline cells combined with multi-busbar (MBB) technology.

• Cell type: N-type monocrystalline TOPCon (210R)
• Cell configuration: 132 cells [2 × (11 × 6)]
• MBB design improves current collection and reduces resistive losses
• Lower risk of hot spots and micro-cracking

Electrical Performance (STC)

• Nominal maximum power (Pmax): 625 W
• Maximum power voltage (Vmp): 41.13 V
• Maximum power current (Imp): 15.20 A

• Module efficiency: 23.1%
• Power tolerance: 0 ~ +3%

Bifacial Performance

The bifacial design allows the rear side of the module to generate additional energy from reflected light.

• Bifaciality factor: 80 ± 5%
• Rear-side energy gain depends on installation height, tilt, and surface reflectivity
• Suitable for ground-mounted, elevated, and high-albedo installations

Temperature Performance

• Temperature coefficient of Pmax: -0.28% / °C
• Temperature coefficient of Voc: -0.23% / °C
• Temperature coefficient of Isc: +0.045% / °C
• Lower operating temperature improves real-world energy yield
