This reduces shading losses from the metallization grid, improves module aesthetics, and limits the impact of partial soiling on energy yield. - **Up to 22.6% efficiency - segment-leading level** - The 21.9-22.6% efficiency range is essentially on par with the best N-type competitors in this power class (Hanersun Hitouch 5N 22.65%, Risen RSM144-9 22.6%, Q-SUN Qrystal N8 22.65%), confirming the series is not technologically behind the market leaders. - **High unit power up to 585 Wp** - Modules rated at 565-585 Wp reduce the number of panels needed to reach a given installed capacity, lowering mounting structure, DC cabling, and labor costs - particularly valuable in commercial and industrial projects with limited roof area. - **Tier-1 bankable manufacturer** - LONGi Solar has operated since 2000 and is classified as a Tier-1, bankable manufacturer, which eases project financing through banks and investment funds and increases confidence in the durability of the factory warranty. - **Low temperature coefficient of -0.29%/°C** - A power temperature coefficient of -0.29%/°C is more favorable than the -0.35% to -0.40%/°C typical of older PERC modules, resulting in lower production losses at high operating temperatures, such as during summer months. ## Cons - **Shorter warranty than N-type segment leaders** - The 15-year product warranty and 25-year power warranty fall below the current market standard for top-tier TOPCon panels (Jinko Tiger Neo, Trina Vertex S+, JA Deep Blue), which now offer 25-year product warranties and 30-year power warranties with an 87.4% output floor. - **No bifacial variant available** - The module has a monofacial (single-sided) design, while some competing 585 Wp N-type series (e.g., Risen RSM144-9-560-585BNDG) are offered in bifacial versions that capture additional rear-side energy yield in ground-mount or carport installations. - **Price premium of HPBC technology** - Independent reviews of HPBC-based Hi-MO series indicate a higher price versus comparable TOPCon panels of similar power and efficiency, which can extend the payback period for typical residential/prosumer installations. ## About this series The Longi Solar Hi-MO X6 Explorer (LR5-72HTH 565~585M) was designed with the goal of maximizing yield from every square meter - without compromising on aesthetics and durability. Its key advantage is the **HPBC (Back Contact) technology**, which means the electrical contacts are moved to the rear of the cell. This results in a “cleaner” front side of the module, and limits losses from shading in the wiring paths, translating to more stable performance in real-world conditions - even under poorer light, high temperatures, or partial soiling. In practice, this is a series for investors who wish to **maximize production in space-limited installations** and simultaneously reduce the number of panels needed to achieve a certain power output. These modules will perform particularly well in commercial and industrial installations, on rooftops with complex geometries, and in projects where cable and construction costs matter. An additional asset is **good performance in heat** and **enhanced mechanical durability**, which is crucial under wind and snow loads. ## Notable figures - At 22.3% efficiency, this panel is on par with typical \*\*database\*\* modules - Power density of 222.6 W/m² packs 4.5 W/m² more into the same footprint vs \*\*database\*\* median (218.1 W/m²) - At -0.29%/°C, hot weather performance is typical for \*\*database\*\* panels - In the top 37% for efficiency among all N-type panels ## Questions ### What is HPBC technology in the LONGi Hi-MO X6 Explorer panels and does it actually make a difference? HPBC (High Performance Back Contact) relocates all current-carrying busbars to the rear of the cell, leaving the front surface fully exposed to light. This eliminates shading losses from metallization and improves light absorption. The result is module efficiency up to 22.6% and more stable output under low-irradiance conditions or high cell temperatures - without requiring a bifacial design. ### What warranty does the LONGi Hi-MO X6 Explorer LR5-72HTH 565-585M come with? LONGi provides a 15-year product warranty covering material and workmanship defects, plus a 25-year power output warranty. The power guarantee specifies at least 98.5% of rated power after year one and no less than 88.9% after 25 years. This is one of the stronger warranty packages available from a Tier 1 manufacturer in the current market. ### How do the Hi-MO X6 Explorer panels perform on hot days - for example on a dark roof in summer? The temperature coefficient of Pmax for the LR5-72HTH series is -0.29%/°C, which is better than standard PERC modules (typically -0.34 to -0.35%/°C). On a roof surface reaching 70°C, power loss relative to STC is approximately 11.6% - noticeably lower than older cell technologies. This translates into higher annual energy yield in temperate and continental climates. ### How heavy is the LONGi Hi-MO X6 Explorer panel and is it suitable for a standard residential pitched roof? The LR5-72HTH-585M module measures 2278 × 1134 × 35 mm and weighs 27.5 kg. This is a large-format panel designed primarily for commercial and industrial rooftop or ground-mount systems. For residential pitched roofs, a structural assessment is recommended before installation, as the module weight is significantly higher than typical residential panels in the 400-430 Wp range. ### How many LONGi Hi-MO X6 Explorer 585 Wp panels do I need for a 10 kWp system? At 585 Wp per panel, just 18 modules are needed to reach 10.53 kWp. With efficiency up to 22.6%, each panel generates more energy per square meter than lower-efficiency alternatives, reducing total roof area, shortening DC cabling runs, and lowering overall BoS costs compared to systems built with less efficient modules. ### Do the LONGi Hi-MO X6 Explorer panels require power optimizers or microinverters? No - the Hi-MO X6 Explorer modules are fully compatible with standard string inverters using MPPT tracking and do not require power optimizers or microinverters. HPBC cell technology already reduces the effect of partial shading on string output at the cell level. Optimizers are worth considering only when the roof has multiple azimuths, severe localized shading, or complex geometry that cannot be resolved by string splitting. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/l-gi-le-pm-t-pmd-059-f138-lr-5-72-hth-565-585-m-30-30-and-15-94acc70498c8.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +2.5 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +2.3 pp, +5 yr warranty | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Lighter, +2.1 pp, +5 yr warranty | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Lighter, +2.1 pp, +5 yr warranty | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Lighter, +2.1 pp, +5 yr warranty | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | -30 W, +2.0 pp, +5 yr warranty | | [AIKO AIKO-A625-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a625-mah72dw) | 625 W | +50 W, heavier, +1.9 pp | | [Longi Solar RL530HM](https://comparepv.com/panel/longi-solar-rl530hm) | 530 W | -45 W, hotter, -1.6 pp | | [Longi Solar RL535HM](https://comparepv.com/panel/longi-solar-rl535hm) | 535 W | -40 W, hotter, -1.4 pp | | [Longi Solar LR5-72HBD-540M](https://comparepv.com/panel/longi-lr5-72hbd-540m) | 540 W | Hotter, -1.4 pp, +5 yr warranty | | [Longi Solar RL540HM](https://comparepv.com/panel/longi-solar-rl540hm) | 540 W | -35 W, hotter, -1.2 pp | | [Longi Solar LR5-72HPH-545M](https://comparepv.com/panel/longi-lr5-72hph-545m) | 545 W | -30 W, hotter, -1.2 pp | | [Longi Solar RL545HM](https://comparepv.com/panel/longi-solar-rl545hm) | 545 W | -30 W, hotter, -1.0 pp | | [Longi Solar LR5-72HBD-550M](https://comparepv.com/panel/longi-lr5-72hbd-550m) | 550 W | Hotter, -1.0 pp, +5 yr warranty | | [Longi Solar RL550HM](https://comparepv.com/panel/longi-solar-rl550hm) | 550 W | -25 W, hotter, -0.8 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +75 W, +2.9 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/longi-lr5-72hth-575m 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.
