Its key advantage is the **anti-dust construction**, where a special frame and edge solution helps dust and dirt naturally slide off due to gravity and rain. This translates into **higher energy production over time** and more stable system performance, especially in locations exposed to dust, field silt, road particulates, or industrial facilities. The panels utilize cutting-edge monocrystalline wafers in a back-contact (HPBC) structure with light-enhancing solutions, supporting high efficiency without the need for "non-optimal" parameters. For investors, lower service and cleaning requirements are also crucial, meaning reduced operational costs for utility-scale farms, commercial rooftops, and building-integrated systems. The series also stands out for its **enhanced mechanical reliability** - thanks to the patented frame and advanced sealing, which facilitates module selection where durability and predictable yields are paramount. ## Notable figures - At 23.1% efficiency, this panel is on par with typical \*\*N-type 600-650W\*\* modules - 231.4 W/m² power density - 3.7 W/m² more than \*\*N-type 600-650W\*\* median (227.7 W/m²), more power per roof area - Temperature coefficient of -0.28%/°C matches the \*\*N-type 600-650W\*\* median - At 28.5 kg, this panel is 4.3 kg lighter than \*\*N-type 600-650W\*\* median (32.8 kg) - easier handling during installation - #1617 for efficiency, #1347 for temperature performance out of 14129 panels ## Questions ### How does the anti-dust technology work in the LONGi Hi-MO X6 Guardian LR7-72HTHF panels? The anti-dust design relies on a patented frame where the short-side rail sits flush with the module glass. This allows dust, mud, and particulate deposits to slide off naturally under gravity and rainfall without accumulating on the frame ledge. The solution is backed by over 120 patents and validated through more than 500 days of field testing. In practice, it means measurably lower soiling losses and reduced cleaning frequency. ### What cell technology is used in the LONGi Hi-MO X6 Guardian LR7-72HTHF series and what is its efficiency? The LR7-72HTHF series uses N-type cells in an HPBC (Hybrid Passivated Back Contact) architecture. Moving electrodes to the rear of the cell eliminates front-side metallization shading, enabling module efficiency up to 23.3% at a maximum power output of 630 Wp. N-type technology also delivers lower light-induced degradation (LID) and a lower temperature coefficient compared to conventional P-type PERC cells. ### What warranty does LONGi offer on the Hi-MO X6 Guardian LR7-72HTHF series? LONGi provides a 15-year product warranty covering material and workmanship defects, along with a 25-year linear power output warranty. After 25 years of operation, output should remain at no less than 87.4% of rated power. LONGi is an independently verified Tier 1 manufacturer, which adds confidence that warranty claims will be honored over the module's full service life. ### Are LONGi Hi-MO X6 Guardian LR7-72HTHF panels suitable for utility-scale PV farms near roads or industrial facilities? Yes, the Guardian series is specifically engineered for high-soiling environments: farms near unpaved roads, agricultural fields, industrial plants, and semi-arid regions. The self-cleaning frame reduces O&M costs and cleaning frequency. The modules are rated for 5400 Pa front-load and 2400 Pa rear-load, making them well-suited for large ground-mount systems and industrial rooftops. ### How does the Hi-MO X6 Guardian LR7-72HTHF series perform in high temperatures during summer? The temperature coefficient of Pmax for this series is -0.28%/°C, better than typical PERC modules at around -0.35%/°C. In practice, for every degree above 25°C the module loses less power than older P-type technology. This translates into higher energy yield on hot, sunny days, exactly when the system should be generating the most electricity. ### Is the LONGi Hi-MO X6 Guardian LR7-72HTHF a bifacial module? No, the LR7-72HTHF Guardian Anti-Dust variant is a monofacial module with a backsheet instead of a rear glass. While this limits potential albedo gains, it is a deliberate design choice that reduces module weight and simplifies installation. The high HPBC cell efficiency of up to 23.3% effectively compensates for the absence of rear-side light harvesting. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/lr-7-72-hthf-605-630-m-anti-dust-frame-20240527-v2-dc06a42b2-3326a3ea51f8.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +25 W, +2.1 pp, +5 yr warranty | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +50 W, +1.9 pp, +5 yr warranty | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, +1.9 pp, +5 yr warranty | | [WINAICO WST-675BKX72-A2](https://comparepv.com/panel/winaico-wst-675bkx72-a2) | 675 W | +50 W, +1.9 pp, +5 yr warranty | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +45 W, +1.7 pp, +5 yr warranty | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +45 W, +1.7 pp, +5 yr warranty | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, +1.7 pp, +5 yr warranty | | [Longi Solar LR8-66HGD-595M](https://comparepv.com/panel/longi-lr8-66hgd-595m) | 595 W | Heavier, -1.1 pp, +5 yr warranty | | [Longi Solar LR7-72HGD-600M](https://comparepv.com/panel/longi-lr7-72hgd-600m) | 600 W | Heavier, -0.9 pp, +5 yr warranty | | [Longi Solar 600M](https://comparepv.com/panel/longi-600m) | 600 W | -25 W, heavier, -0.7 pp | | [Longi Solar LR7-72HTH-605M](https://comparepv.com/panel/longi-lr7-72hth-605m) | 605 W | -20 W, -0.7 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +55 W, +2.1 pp, +5 yr warranty | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +75 W, heavier, +1.9 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +70 W, heavier, +1.8 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +45 W, +1.7 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/longi-lr7-72hthf-625m Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
