Application: The LONGi Hi-MO 7 LR8-66HGD 595W is a Hi-MO 7 solar panel engineered for residential rooftop installations, delivering a maximum power output of 595W at 22.0% module efficiency. Under standard test conditions it produces an open-circuit voltage (Voc) of 47.8V, a short-circuit current (Isc) of 15.30A, a voltage at maximum power (Vmp) of 39.1V and a current at maximum power (Imp) of 14.91A. The panel measures 2382×1134×30mm and weighs 32.5kg, with an Anodized aluminum alloy 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 5400Pa and a rear-side static load of 2400Pa, with a Pmax temperature coefficient of -0.280%/°C, a Voc coefficient of -0.230%/°C and an Isc coefficient of +0.049%/°C. With a bifaciality of 80±5%, it also captures additional energy reflected onto its rear side. The Hi-MO 7 LR8-66HGD 595W 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.

Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in the UAE that rests with the local authorities (DEWA, ADDC, SEWA). Confirm the grid code, import requirements and any local certification with them, or with us, before you order.
