LONGi LR8-66HGD-615M – 615 Wp, n-type TOPCon
The LONGi LR8-66HGD-615M is a high-power, bifacial dual-glass solar module using advanced n-type TOPCon cells and a nominal power of 615 Wp. It achieves a module efficiency of ≈22.8%, has dimensions of 2382 × 1134 × 30 mm and a weight of 33.5 kg, and is built for 1500 V systems with an IP68 junction box (3 diodes) and a robust mechanical rating (front 5400 Pa / rear 2400 Pa). The module offers a 12-year materials & workmanship warranty and a 30-year linear performance warranty (≈87.4% remaining at year 30), making it suitable for commercial and utility installations that prioritise long-term yield.
✅ Benefits for installers
• High power — 615 Wp: More kW per module reduces BOS and installation cost per kW.
• Excellent efficiency — ≈22.8%: Maximises energy production per m² for space-constrained sites.
• Bifacial glass-glass construction: Higher rear-side yield (bifaciality ~80±5%) for increased total energy on reflective surfaces.
• Robust mechanical ratings: 5400 Pa front and 2400 Pa rear static load capability for harsh climates.
• Long-term security: 12 years product (materials & processing) + 30 years linear power warranty (≈87.4% at year 30).
• Installer-friendly specs: 1500 V system voltage, IP68 junction box (3 diodes), and standard 132-cell layout simplify integration.
• Excellent efficiency — ≈22.8%: Maximises energy production per m² for space-constrained sites.
• Bifacial glass-glass construction: Higher rear-side yield (bifaciality ~80±5%) for increased total energy on reflective surfaces.
