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
