The LONGi LR6-72HBD 370M is a high-efficiency bifacial mono PERC solar panel with dual-glass construction and a maximum power output of 370W. Featuring excellent low-light performance, reduced degradation, and 1500V system compatibility, it is ideal for residential, commercial, and utility-scale projects.
Key Benefits
Bifacial Energy Gain: Rear-side generation adds up to 25% more power output using reflected sunlight.
Dual Glass Durability: Double 2.0mm tempered glass layers provide mechanical strength and long-term performance.
High Efficiency: Up to 18.4% front-side module efficiency for better energy yield in limited space.
Low Degradation: First-year power loss <2%, followed by annual degradation of <0.45% over 30 years.
PID Resistance: Optimized cell process and BOM ensure solid resistance against potential-induced degradation.
Special Technology
Optimized Electrical Design: Lower current reduces hot spot risks and improves temperature coefficient.
Extended Product Life: 30-year lifespan supported by superior glass-glass structure and LID-resistant cells.
High System Voltage: 1500V compatibility lowers BOS costs in large-scale arrays.
Certified Reliability: Complies with IEC 61215, IEC 61730, UL 1703, and more.
Warranty
Guaranteed ≤2% first-year degradation, then <0.45% annually for 30 years.
Best Uses
Commercial Rooftops: Excellent for maximizing energy harvest from both panel sides.
Utility-Scale Projects: Suitable for ground-mounted installations seeking low LCOE and high durability.
Snowy or Reflective Surfaces: Perfect for regions that offer strong albedo gain through bifaciality.
