Actual gain depends on ground albedo, but the effect is measurable on light-colored roofs, membranes, and ground-mount installations. - **N-type + half-cut cells reduce losses** - Combining N-type cells with a half-cut architecture lowers resistive losses and improves module behavior under partial shading compared to older full-cell PERC designs, resulting in more stable energy output under less-than-ideal conditions. - **Low temperature coefficient of -0.28%/°C** - The power temperature coefficient is -0.28%/°C, notably better than the typical -0.35 to -0.40%/°C for PERC modules. This means smaller power losses in summer heat, with cells rated to operate up to +85°C - relevant for dark roofs or hot climates. - **Efficiency up to 23.1%, near segment top** - Maximum efficiency of 23.1% places the series close to the best peer comparables in the segment (DAH Solar DHN-66Z16/DG and DHN-72R20/DG at 23.14%, Leapton LP182\*182 at 22.36% for the same 625 Wp rating), confirming its technological competitiveness among other 625 Wp module makers. - **Tier-1 BNEF and AAA bankability** - LONGi is listed as a BloombergNEF Tier 1 manufacturer (including Q2 2026) and has maintained an AAA bankability rating in the PV Tech ModuleTech report for 25 consecutive quarters, easing project financing for utility-scale PV farms and commercial installations using this series. ## Cons - **Product warranty limited to 12 years** - The standard product warranty is 12 years, while some Tier-1 competitors (e.g., Trina Solar under its TrinaProtect program) now offer a 25-year product warranty bundled with a 25-year power warranty. The 30-year linear power warranty partially offsets this gap, but the shorter materials/workmanship coverage period can matter when comparing bids for large commercial projects. ## About this series The Longi Solar Hi-MO 7 LR7-72HGD 595-625M series is designed to maximize energy yield where every square meter and every operating hour count. Its key feature is the **bifacial structure in a dual-glass system**, which genuinely increases production by capturing reflected light from the substrate-particularly on light-colored roofs, membranes, and ground-mounted installations with properly prepared terrain. The application of modern monocrystalline cells in a half-cell architecture translates to **better performance under partial shading and lower internal losses**, enabling more stable energy production in less-than-ideal conditions. This series also boasts **high resistance to demanding environments**-the double glass supports durability and minimizes the risk of micro-cracks over the long term. Another advantage is **excellent performance at high temperatures**, reducing power losses during summer months. This series is primarily intended for PV farms, commercial and industrial installations, and developers seeking to reduce Balance of System (BOS) costs through higher power output per module. ## Notable figures - Efficiency of 22.2% is 0.6pp below the \*\*N-type 600-650W\*\* median (22.8%) - Power density of 222.1 W/m² is 5.6 W/m² below \*\*N-type 600-650W\*\* median (227.7 W/m²) - needs more roof space - Temperature coefficient of -0.28%/°C matches the \*\*N-type 600-650W\*\* median - At 33.5 kg, weight matches the \*\*N-type 600-650W\*\* median - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### What warranty does LONGi Solar offer on the Hi-MO 7 LR7-72HGD 595–625M series? LONGi provides a 12-year product warranty covering materials and workmanship, plus a 30-year linear power output warranty. First-year degradation is capped at 1%, followed by no more than 0.4% per year, guaranteeing at least 87.4% of rated power after 30 years. These are among the strongest warranty terms available for utility-scale modules on the market today. ### What is N-type TOPCon technology and why does it matter in the Hi-MO 7 panels? N-type TOPCon cells used in the Hi-MO 7 LR7-72HGD deliver higher efficiency and lower long-term degradation compared to older PERC technology. A standout feature is the power temperature coefficient of just –0.28%/°C, meaning minimal power loss on hot summer days. Combined with a bifacial ratio of approximately 80%, the module also generates electricity from light reflected off the ground or rooftop surface. ### Are the LONGi Hi-MO 7 LR7-72HGD 625M panels suitable for a large commercial roof or ground-mounted solar farm? Yes, the Hi-MO 7 LR7-72HGD series is purpose-built for commercial, industrial, and utility-scale PV installations. With up to 625 Wp per module and a dual-glass construction, it reduces BoS (Balance of System) costs by delivering more power from fewer modules. The bifacial design is especially beneficial in ground-mount projects with light-colored surfaces, where reflected irradiance can boost energy yield by several percentage points. ### How do Hi-MO 7 LR7-72HGD modules perform under partial shading conditions? The series uses a half-cut cell architecture with 144 cells, splitting the module into independently operating sub-strings. This limits the impact of partial shading — caused by chimneys, antennas, or inter-row shading in tracker installations — to a smaller section of the module, keeping overall output more stable compared to conventional full-cell designs. ### How much does a LONGi Hi-MO 7 LR7-72HGD panel weigh, and what mechanical loads can it handle? Each module weighs approximately 33.5 kg and measures 2382×1134×30 mm. The dual-glass construction (2+2 mm tempered glass) withstands a front static load of 5400 Pa and a rear load of 2400 Pa, along with hail resistance up to 25 mm diameter at 23 m/s. These mechanical ratings make the series well-suited for demanding environments typical of large rooftop and ground-mount PV plants. ### Is the LONGi Hi-MO 7 LR7-72HGD 595–625M series still available for purchase? Yes, the Hi-MO 7 LR7-72HGD 595–625M series is currently in production and commercially available. LONGi Solar is a Tier 1 manufacturer headquartered in China, and this module line is distributed globally through authorized partners. It is recommended to confirm current stock availability and lead times with your local distributor before placing a large order. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/l-gi-le-pm-t-pmd-059-f151-lr-7-72-hgd-595-625-m-v2-30-30-and-24129ee725bf.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +50 W, lighter, +3.0 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +45 W, lighter, +2.8 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -40 W, lighter, +2.6 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +40 W, lighter, +2.6 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -45 W, lighter, +2.4 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +35 W, lighter, +2.4 pp | | [Longi Solar LR8-66HGD-595M](https://comparepv.com/panel/longi-lr8-66hgd-595m) | 595 W | Lighter | | [Longi Solar 600M](https://comparepv.com/panel/longi-600m) | 600 W | Lighter, -5 yr warranty | | [Longi Solar LR7-72HTH-605M](https://comparepv.com/panel/longi-lr7-72hth-605m) | 605 W | Lighter, -5 yr warranty | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +80 W, lighter, +3.0 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +75 W, lighter, +2.8 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +100 W, cooler, +2.8 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +95 W, cooler, +2.7 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +70 W, lighter, +2.6 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +70 W, lighter, +2.6 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +70 W, cooler, +2.6 pp | --- Source: https://comparepv.com/panel/longi-lr7-72hgd-600m 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.
