AXITEC AC-440TGB/108BB 440W Bifacial N-Type TOPCon Solar Panel

All-Black Dual-Glass High-Durability Module

High-performance N-Type TOPCon bifacial solar module designed for residential and commercial rooftops requiring premium aesthetics, strong structural integrity, and consistent long-term energy output.

Built with a dual-glass architecture, this panel minimizes risks of micro-cracking and long-term backsheet degradation common in traditional modules. Its rigid construction and heavy-duty frame allow it to maintain stability under high snow and wind loads while delivering enhanced bifacial energy yield from reflected light.

Product Performance

  • Rated Power: 440W
  • Efficiency: 22.02%
  • Power Tolerance: 0 ~ +5W
  • Temperature Coefficient (Pmax): -0.31%/°C
  • Voltage Coefficient (Voc): -0.26%/°C

Performance Highlights:

  • Stable output in high-temperature environments
  • Improved low-light and early/late-day performance
  • Reduced degradation due to N-Type TOPCon architecture
  • Enhanced energy yield through bifacial design

Durability & Construction

  • Dual-glass structure (2.0 mm tempered glass front and back)
  • Reinforced 25.0 kg rigid frame design
  • Designed for up to 5400 Pa snow load resistance
  • High wind and mechanical stress durability
  • Reduced risk of micro-cracks and thermal backsheet failure

Warranty

  • Product Warranty: 30 years
  • Performance Warranty: 30 years
  • Annual Degradation: ~0.4%
  • End-of-Warranty Output: 87.4%

Long-term performance guarantee ensures stable energy production and minimal efficiency loss over decades.

Physical Characteristics

  • Cell Type: N-Type TOPCon Bifacial Monocrystalline
  • Panel Dimensions: 1762 × 1134 × 30 mm
  • Cell Count: 108 half-cells
  • Frame: Black anodized aluminum
  • Weight: ~25.0 kg
  • Connector Type: MC4-EVO 2 / MC4-EVO 2A / JM608 compatible

Certifications

  • UL 1703
  • Industry-standard IEC / UL photovoltaic safety compliance (category-level certification)

Key Advantages

  • Premium all-black aesthetic for modern rooftops
  • High-efficiency bifacial energy generation
  • Strong structural rigidity for harsh environments
  • Excellent long-term degradation resistance
  • Optimized for residential and light commercial systems

Note on Performance

Panel efficiency and temperature coefficients are key indicators of real-world performance. N-Type TOPCon technology significantly reduces degradation compared to traditional P-Type modules, while bifacial design increases total yield depending on installation conditions and surface reflectivity.
