About the LONGi Hi-MO X10 Scientist LR7-72HVD 645W

The LONGi Hi-MO X10 Scientist LR7-72HVD 645W is a Hi-MO X10 Scientist 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 54.12V, a short-circuit current (Isc) of 15.06A, a voltage at maximum power (Vmp) of 46.55V and a current at maximum power (Imp) of 14.19A. The panel measures 2382×1134×30mm and weighs 33.5kg, with an Anodized aluminum alloy frame and Dual glass, 2.0mm semi-tempered glass. It operates across -40°C to +85°C, with a nominal operating cell temperature of 45±2°C, a maximum system voltage of DC1500V (IEC) and a maximum series fuse rating of 30A. It withstands a front-side static load of 5400Pa and a rear-side static load of 2400Pa, 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 70±5%, it also captures additional energy reflected onto its rear side. The Hi-MO X10 Scientist LR7-72HVD 645W is certified by IEC 61215, IEC 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.
