Hi-MO 5
LONGi Hi-MO 5 is a P-type monocrystalline solar-panel family that includes monofacial Hi-MO 5m and bifacial dual-glass variants in several module sizes.

Hi-MO 5 is a family of P-type monocrystalline modules from LONGi, not one panel. The Hi-MO 5m range includes the 54-cell-format LR5-54HPH series and the larger LR5-72HPH series. LONGi also uses the Hi-MO 5 name for a dual-glass bifacial line, so the complete model code is needed before applying any specification.
Three model schedules
| Series and exact code boundary | Construction | Dimensions | STC efficiency |
|---|---|---|---|
LR5-54HPH-405M to LR5-54HPH-425M, in 5 W steps |
monofacial, single glass | 1722 × 1134 × 30 mm | 20.7–21.8% |
LR5-72HPH-540M to LR5-72HPH-560M, in 5 W steps |
monofacial, single glass | 2278 × 1134 × 35 mm | 20.9–21.7% |
LR5-72HBD-540M to LR5-72HBD-560M (G2), in 5 W steps |
bifacial, dual glass | 2278 × 1134 × 30 mm | 20.9–21.7% |
All three schedules use half-cut P-type PERC cells on LONGi’s M10 wafer format.
The temperature coefficient and nominal operating cell temperature are common across the two datasheets. Their degradation and warranty figures also match: the performance term allows a larger change in the first year followed by a linear annual reduction through year 25.
Variant boundaries
The LR5-72HBD (G2) schedule has a dual-glass construction and a 30-year performance warranty. The two monofacial Hi-MO 5m schedules have a 25-year performance term. Dimensions, bifaciality and warranty are therefore suffix-specific.
On 31 July 2026 the MCS Product Directory contained the following exact wattage boundaries:
LR5-54HPH-395MthroughLR5-54HPH-435Min 5 W stepsLR5-72HPH-525MthroughLR5-72HPH-575Min 5 W stepsLR5-72HBD-500M,-505M,-510M,-515M,-520M,-525M,-530M,-535M,-540M,-555M,-560Mand-565M
That certification boundary is broader than the three technical schedules above. An MCS-listed wattage outside those schedules needs its own matching datasheet before dimensions, efficiency or warranty values are applied.
Availability
Hi-MO 5 remains on LONGi’s product site and exact module records were current in MCS on 31 July 2026. Neither establishes stock at a particular UK supplier.
