Latest N-type TOPCon Bifacial Solar panels are now AVAILABLE at AECO !!

TOPCon Bifacial Solar Panels with N-Type Cells offer several key advantages making them superior in performance and overall energy generation. Here’s a detailed comparison:

Advantages and USP of TOPCon Bifacial Solar Panels with N-Type Cells

1. Higher Efficiency
   • TOPCon (Tunnel Oxide Passivated Contact) technology allows for higher conversion efficiencies of 24-28%, outperforming traditional monocrystalline panels.
   • N-type cells have reduced recombination losses and improved carrier lifetimes, leading to greater energy generation.
2. Bifacial Energy Generation:
   • Unlike standard mono panels, TOPCon bifacial panels can generate power from both the front and rear sides.
   • This increases energy yield by up to 10-15% depending on the ground reflectivity (albedo), such as snow, sand, or concrete surfaces.
3. Superior Low-Light Performance:
   • TOPCon N-type panels perform better in low-light conditions, such as cloudy weather, dawn, or dusk, ensuring consistent energy generation throughout the day.
4. Lower Temperature Coefficient:
   • These panels have a lower temperature coefficient (around -0.30%/°C) compared to mono panels (typically -0.35%/°C).
   • This means they perform better in hot climates, maintaining higher efficiency even under high temperatures.
5. Reduced Degradation and Longer Lifespan:
   • N-Type TOPCon panels exhibit lower Light-Induced Degradation (LID) and Potential-Induced Degradation (PID):
     • LID: N-type cells are immune to boron-oxygen defects, reducing early efficiency loss,
     • This ensures a higher lifespan with better performance warranties.
   • Annual degradation is typically 0.3-0.4%, compared to 0.5-0.6% for standard mono panels
6. Higher Energy Yield:
   • Thanks to bifaciality, lower degradation, and better temperature resistance, TOPCon bifacial panels deliver a higher kWh/kWp energy yield over their lifetime compared to mono panels.
7. Durability and Stability:
   • N-type cells have better resistance to metallic impurities and environmental stress, ensuring reliable performance under extreme conditions like high humidity and temperature.
8. Higher Return on Investment (ROI):
   • With improved efficiency, bifacial energy gains, and longer lifespan, TOPCon panels offer better ROI by maximizing energy output per square meter.
9. Sustainability and Innovation:
   • TOPCon technology uses advanced manufacturing techniques that are compatible with existing PERC production lines, ensuring cost efficiency while advancing innovation.
10. Lower BOS (Balance of System) Costs:
    • Due to higher efficiency and bifacial generation, fewer panels are needed for the same energy output, reducing system installation costs (structure, wiring, labor).

Key Differences Between TOPCon Bifacial (N-Type) and Standard Mono Panels

Conclusion

TOPCon bifacial solar panels with N-Type cells significantly outperform standard mono panels in terms of efficiency, energy yield, durability, and overall lifetime performance. Their bifacial nature and advanced cell technology make them ideal for projects aiming for maximum energy generation and long-term cost savings, particularly in large-scale commercial, industrial, or utility installations.
