LONGi Solar Hi-MO 7 LR8-66HGD-610M Solar Module 610 Watt Silver/white n-type TOPCon Bifacial Glass-Glass 12 Years Product Warranty

The LONGi LR8-66HGD-610M is a 610 Wp bifacial glass-glass module built on LONGi’s advanced HPDC n-type cell platform, delivering a module efficiency of ≈22.6%. It uses 132 cells, measures 2382 × 1134 × 30 mm, weighs 33.5 kg, offers ~80% ±5% bifaciality, and comes with LONGi’s lifecycle guarantees (12 years materials & processing + 30 years linear power warranty — ≈87.4% at year 30). The module is rated for 1500 V DC, has a Pmax temperature coefficient of −0.28% / °C, and robust mechanical specs (front snow 5400 Pa / back wind 2400 Pa). 

 • High specific power — 610 Wp: fewer modules per kWp lowers mounting, logistics and BOS costs.
• High area efficiency (~22.6%): more energy per m² — good for constrained roofs and utility arrays.
• n-type HPDC cells: reduced LID/LeTID and improved low-irradiance performance for stable long-term yield.
• Bifacial glass-glass design: rear-side gains (~10–20% typical, depending on albedo) increase annual energy yield.
• Strong mechanical durability: 5400 Pa front / 2400 Pa back and hail resistance for harsh-site reliability.
• Long-term warranty & low degradation: 12 years materials warranty + 30 years linear power warranty (≈87.4% at year 30) for procurement confidence. 

• Rated power (Pmax): 610 Wp.
• Cell type / count: n-type HPDC — 132 cells (6×22).
• Module design: Bifacial, Glass / Glass (2.0 + 2.0 mm).
• Module efficiency: ≈22.6% (610 M bin).
• Dimensions: 2382 × 1134 × 30 mm.
• Weight: 33.5 kg.
• Power tolerance: 0 ~ +3%.
• Temperature coeff. (Pmax): −0.28% / °C.
• Mechanical loads: Front 5400 Pa | Back 2400 Pa; Hail tested (25 mm @ 23 m/s).
• Electrical / system limits: 1500 V DC max system voltage | Max series fuse 35 A; output cable 4 mm², +400 / −200 mm; junction box IP68.
• Warranties / degradation: 12 years materials & processing | 30 years linear power warranty (≈87.4% remaining at year 30).
