About the LONGi Hi-MO 9 Edge LR8-66HYD 645W

The LONGi Hi-MO 9 Edge LR8-66HYD 645W is a Hi-MO 9 solar panel engineered for residential rooftop installations, delivering a maximum power output of 645W at 23.9% module efficiency. Under standard test conditions it produces an open-circuit voltage (Voc) of 49.67V, a short-circuit current (Isc) of 16.38A, a voltage at maximum power (Vmp) of 38.66V and a current at maximum power (Imp) of 12.51A. The panel measures 2382×1134×30mm and weighs 35.7kg, with a High Strength Frame and Dual glass, 2.0+2.0mm heat strengthened glass. It operates across -40°C to +85°C, a maximum system voltage of DC1500V (IEC/UL) and a maximum series fuse rating of 35A. It withstands a front-side static load of 6000Pa and a rear-side static load of 3000Pa, with a Pmax temperature coefficient of -0.260%/°C, a Voc coefficient of -0.200%/°C and an Isc coefficient of +0.050%/°C. With a bifaciality of 75±5%, it also captures additional energy reflected onto its rear side. The Hi-MO 9 Edge LR8-66HYD 645W is certified by IEC 61215, IEC 61730, UL 61730, ISO9001:2015, ISO14001:2015, ISO45001:2018 and IEC62941 and is backed by a 12-year product warranty and a 30-year performance warranty from LONGi Solar.
