Hi-MO 7 is LONGi’s bifacial dual-glass module family using n-type HPDC cells. The LR7-72HGD V07 series spans 585 W to 620 W. Current MCS records also include other LR7-72HGD wattages and the LR8-66HGD series, so Hi-MO 7 should not be treated as one physical panel.

The exact MCS-listed codes on 31 July 2026 were:
LR7-72HGD-565M,-570M,-575M,-585M,-590M,-595M,-600M,-605M,-610M,-615M,-630Mand-635MLR8-66HGD-595M,-600M,-605M,-610M,-615M,-620Mand-625M
The certification boundary is broader than the manufacturer schedules above. An MCS-listed wattage outside those schedules needs its own matching datasheet before physical, electrical or warranty values are applied.
LR7-72HGD V07 specification
LR7-72HGD V07 measures 2382 by 1134 mm, weighs 33.5 kg and reaches 23.0% module efficiency. It is dual-glass and bifacial, with an 80% bifaciality value and a tolerance of plus or minus five percentage points.
Rated power in the table is the front-side standard test conditions value. Rear-side contribution is not included in the nameplate wattage.
The power temperature coefficient is -0.28% per degree Celsius. The performance warranty curve permits a first-year reduction of less than 1%, followed by a 0.4% annual linear reduction to the year-30 retained output. Those terms belong to LR7-72HGD V07 and should not be transferred to a different suffix without checking its warranty.
Family and register boundaries
The Hi-MO 7 family includes LR5-72HGD, LR7-72HGD and the separate utility-scale LR8-66HGD format. Their wattage tables and dimensions differ: LR5-72HGD is 2278 mm long, while the LR7 and LR8 formats above are 2382 mm long.
The certificate must match the complete suffix on the module label and product record.
Availability
Hi-MO 7 remains on LONGi’s European product site and its exact module records were current in MCS on 31 July 2026.
