LONGi LR7-72HGD 620W N-Type Bifacial Double-Glass Solar Panel

What it is: A high-output, high-efficiency panel built for commercial, industrial, and utility-scale solar projects.

Key specs:

• Power output: 620W | Module efficiency: up to 23.0%
• Cell technology: HPDC N-type | Design: bifacial double-glass
• Bifaciality factor: 80% ±5%
• Max system voltage: 1,500V
• Temperature coefficient: -0.28%/°C (Pmax)

Mechanical ratings: Front snow load 5,400 Pa | Rear wind load 2,400 Pa — built for harsh climates

Built for: Utility-scale solar farms, commercial rooftops, industrial projects, ground-mount systems, agricultural and community solar

Why it matters:

• HPDC N-type cells = higher efficiency, lower degradation, better low-light/high-temp performance than P-type
• Bifacial design = extra output from reflected light on the rear
• Double-glass construction = better moisture/fire resistance, lower microcrack risk, longer lifespan
• 1500V compatibility = longer strings, less wiring, lower system costs
• Certified IEC & UL — bankable for institutional projects

Warranty: 12 years product | 30 years linear power performance
