The gap is small but places Hi-MO 7 below the segment leaders on this specific metric. - **12-year product warranty trails market leaders** - While the 30-year power warranty is competitive, the standard 12-year product warranty lags behind some Tier-1 rivals, e.g. Trina Solar (15 years) or JA Solar's DeepBlue line (25 years), which may matter to investors weighing long-term service risk. ## About this series The Longi Solar Hi-MO 7 series is a technologically advanced solution based on innovative **HPDC cell technology**, which represents a milestone in the development of N-type bifacial modules. Thanks to precise optimization of the silicon structure, these panels offer significantly higher energy conversion efficiency and a more favorable temperature coefficient, which guarantees stable power production even during extreme heat. These modules effectively solve the problem of long-term performance loss, providing **exceptional resistance to PID and LID degradation**, which translates into a longer lifespan for the entire installation. This series was designed primarily with photovoltaic farms and large-scale commercial projects in mind, where the priority is minimizing the LCOE cost. What distinguishes Hi-MO 7 from competing products is, above all, its **excellent bifacial efficiency**, enabling intensive energy harvesting from reflected light even with less favorable ground parameters. The robust construction using double glass ensures **maximum mechanical durability** and full operational safety in demanding weather conditions. By choosing this series, investors gain the certainty of the highest yields from every square meter of surface area, making it one of the most cost-effective choices in today's modern photovoltaics market. ## Notable figures - At 22.8% efficiency, this panel is on par with typical \*\*N-type 550-600W\*\* modules - Power density of 228.4 W/m² packs 3.9 W/m² more into the same footprint vs \*\*N-type 550-600W\*\* median (224.5 W/m²) - At -0.28%/°C, hot weather performance is typical for \*\*N-type 550-600W\*\* panels - At 31.8 kg (2.3 kg above \*\*N-type 550-600W\*\* median of 29.5 kg), requires checking roof load capacity - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### What is HPDC technology in the LONGi Solar Hi-MO 7 panels and how does it differ from standard N-type cells? HPDC (Hybrid Passivation Dual-junction Cell) technology combines two different passivation techniques on the front and rear cell surfaces to reduce carrier recombination. The result is a module efficiency of 22.8% and an excellent Pmax temperature coefficient of -0.28%/°C. In practice, this delivers better energy yield than conventional N-type TOPCon cells and lower power losses under high operating temperatures. ### What warranty comes with the LONGi Solar Hi-MO 7 solar panels? LONGi provides a 12-year product warranty covering materials and workmanship, plus a 30-year linear power output warranty. The power warranty guarantees that after 30 years of operation the panel retains at least 87.4% of its rated output. This is one of the longest power warranties currently available on the market, making it especially relevant for utility-scale and large commercial PV projects. ### Do the Hi-MO 7 590W panels perform well in hot weather? Yes. The Pmax temperature coefficient of -0.28%/°C is among the best figures for bifacial modules in this power class. For every degree Celsius the cell temperature rises above 25°C, the panel loses only 0.28% of its power — significantly less than P-type PERC technology, where losses typically reach 0.35–0.40%/°C. The Hi-MO 7 series therefore maintains stable energy production even in extreme heat conditions. ### Is the LONGi Hi-MO 7 series suitable for a residential rooftop installation? The Hi-MO 7 590W panel measures 2278×1134 mm and weighs 31.8 kg, making it primarily intended for utility-scale solar farms and large commercial installations. For a typical residential rooftop, smaller, lighter modules are generally a better fit. An installer should assess the roof's load-bearing capacity and available mounting area before specifying these modules. ### What does the bifacial design mean for the Hi-MO 7, and on what surface type does it deliver the most value? Hi-MO 7 bifacial modules achieve a bifaciality ratio of approximately 80%, meaning the rear side can generate up to 80% of the front-side power from reflected irradiance. The greatest gain comes from ground-mounted installations over high-albedo surfaces such as sand, gravel, concrete, or snow. LONGi estimates an additional 5–30% energy yield compared to monofacial modules, depending on the ground albedo of the site. ### How well does the LONGi Hi-MO 7 resist PID and LID degradation over time? The N-type HPDC cells used in the Hi-MO 7 series are structurally resistant to both Potential Induced Degradation (PID) and Light Induced Degradation (LID). N-type cell architecture eliminates the primary degradation mechanisms associated with P-type PERC cells, resulting in more stable energy production throughout the 30-year power warranty period and reduced long-term yield loss risk in utility-scale installations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/l-gi-le-pm-t-pmd-059-f139-lr-5-72-hgd-560-590-m-v1-30-30-and-c9665185c015.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -30 W, lighter, +2.0 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +50 W, lighter, +2.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -35 W, lighter, +1.8 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +45 W, lighter, +1.8 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +40 W, cooler, +1.6 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | -40 W, 16 kg lighter, +1.6 pp | | [Longi Solar RL530HM](https://comparepv.com/panel/longi-solar-rl530hm) | 530 W | -60 W, hotter, -2.1 pp | | [Longi Solar RL535HM](https://comparepv.com/panel/longi-solar-rl535hm) | 535 W | -55 W, hotter, -1.9 pp | | [Longi Solar LR5-72HBD-540M](https://comparepv.com/panel/longi-lr5-72hbd-540m) | 540 W | -50 W, hotter, -1.9 pp | | [Longi Solar RL540HM](https://comparepv.com/panel/longi-solar-rl540hm) | 540 W | -50 W, hotter, -1.7 pp | | [Longi Solar LR5-72HPH-545M](https://comparepv.com/panel/longi-lr5-72hph-545m) | 545 W | Hotter, -1.7 pp, -5 yr warranty | | [Longi Solar RL545HM](https://comparepv.com/panel/longi-solar-rl545hm) | 545 W | Hotter, -1.5 pp, -5 yr warranty | | [Longi Solar LR5-72HBD-550M](https://comparepv.com/panel/longi-lr5-72hbd-550m) | 550 W | -40 W, hotter, -1.5 pp | | [Longi Solar RL550HM](https://comparepv.com/panel/longi-solar-rl550hm) | 550 W | Hotter, -1.3 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +60 W, lighter, +2.4 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +55 W, lighter, +2.2 pp | --- Source: https://comparepv.com/panel/longi-lr5-72hgd-590m Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
