Description
The LONGi Hi-MO 7 LR8-66HGD-620M is a 620W, 132 half-cell bifacial module from LONGi's Hi-MO 7 range, built on n-type HPDC (Hybrid Passivated Dual-junction Cell) technology. Its dual-glass construction and up to 80% bifaciality make it a strong choice for ground-mount, carport and large rooftop systems where rear-side gain adds real yield.
- 620W front-side output with 23.0% module efficiency
- N-type HPDC (Hybrid Passivated Dual-junction Cell) half-cell technology for lower operating temperature
- Bifacial dual glass (2.0 + 2.0mm heat-strengthened) – bifaciality 80 ±5%
- Low degradation: <1% in year one and 0.4% per year thereafter
- Positive power tolerance of 0 to +3%
- Rated for 5400Pa front / 2400Pa rear static load and 25mm hail
- 12-year product and 30-year linear power warranty
