Overview
The LONGi LR8-66HGD-620M LR8-66HGD is a 620W bifacial solar panel built on N-Type cell technology, delivering 23.0% module efficiency for utility, commercial, and large residential arrays. It combines 132 half-cut cells, a clear backsheet, and a silver 30mm frame to capture rear-side irradiance while maintaining a low -0.28%/°C temperature coefficient. Rated to 1500 VDC with an IP68 enclosure, it performs reliably across demanding Canadian climates.
Key Features:
- 620W output, 23.0% module efficiency
- N-Type bifacial cells, clear backsheet
- Temp coefficient -0.28%/°C (Pmax)
- Voc 48.78V / Vmp 40.91V
- Isc 16.05A / Imp 15.16A, 35A fuse
- 132-cell (half-cut 66), 93.8″ x 44.6″ x 1.2″
- Silver 30mm frame, 74 lb weight
- 1500 VDC system, IP68, MC4 connectors
- Wind 5400 Pa / Snow 2400 Pa, -40°F to 185°F
- 12-year product, 30-year performance warranty
Ideal for utility-scale, commercial, and high-yield residential installations where bifacial gain and low degradation matter. With first-year degradation of 1% and 0.4% annually, it suits ground mounts and reflective surfaces, integrating with standard MC4 wiring and 1500 VDC string inverters or optimizers. Order the LR8-66HGD-620M (also listed as LR866HGD620M) from Circuit Solar, in stock in Canada and shipped from Red Deer, AB.
