This delivers up to 22.8% efficiency, clearly ahead of comparable modules such as Jinko Solar JS182MHC120 (21.48%) and Vikram Solar SOMERA (20.91%). - **Low degradation and positive power tolerance** - The manufacturer specifies under 1% power loss in year one and only 0.40% annually thereafter, with a positive power tolerance of 0~+3% (no risk of underdelivered batches). This supports precise energy yield forecasting at the design stage. - **Tier-1 status and strong bankability** - LONGi Solar holds Tier-1 status in the BloombergNEF ranking (confirmed for Q2 2026) and an AAA bankability rating from PV Tech ModuleTech Bankability Ratings for 25 consecutive quarters, easing project financing and long-term warranty backing. - **Mature, current-generation product line** - The series, launched in 2024, comes from a manufacturer operating since 2000 and is not discontinued, ensuring continuity of parts supply, warranty service, and technical support. - **High power in a compact form factor** - 455-465 Wp output in a standard 54-cell half-cut format makes the series attractive for space-constrained roofs where maximizing yield per module matters. ## Cons - **Product warranty below 2026 market standard** - The 15-year product/workmanship warranty falls short of the current market standard for premium N-type TOPCon/HPBC panels in 2026, where competitors (Jinko Tiger Neo, JA Deep Blue, Trina Vertex S+, Canadian Solar TOPHiKu6) already offer 25-year product warranties paired with 30-year power warranties. - **No bifacial variant available** - The series is offered only as a monofacial module, while the comparable Luxor Solar ECO LINE TOPCon Glass-Glass Bifacial reaches higher efficiency (23.6%) and captures additional yield from reflected light in ground-mount or high-albedo installations - an option not available in this line. ## About this series The Longi Solar Hi-MO X6 Explorer LR7-54HTH 455~465M series was designed with the goal of maximizing energy yield from the same rooftop area - particularly in locations where efficiency is crucial within limited spaces. The key feature is the application of **rear contact technology (HPBC)**, which minimizes conductor losses and improves performance in real-world conditions, including when the module operates at higher temperatures or is partially shaded. In practice, this translates to more stable energy production during the summer months and reduced daily fluctuations. Panels from this series also stand out with **low power degradation** and **positive power tolerance**, helping installers and investors plan yields more accurately and balance self-consumption effectively. The design is based on **monocrystalline cells in a half-cut configuration**, which enhances performance under uneven sunlight exposure. This is a reliable choice for **residential and commercial installations**, especially when high efficiency, durability, and an aesthetically pleasing, modern design are priorities. ## Notable figures - Efficiency of 22.8% matches the \*\*N-type 450-500W\*\* median - At 227.8 W/m² power density, roof space requirements are typical for \*\*N-type 450-500W\*\* panels - Temperature coefficient of -0.28%/°C matches the \*\*N-type 450-500W\*\* median - Weight of 21.6 kg (2.1 kg below \*\*N-type 450-500W\*\* median of 23.7 kg) allows easier transport and roof mounting - #2714 for efficiency, #1309 for temperature performance out of 14005 panels ## Questions ### What warranty comes with the Longi Solar Hi-MO X6 Explorer LR7-54HTH 455~465M panels? Longi Solar offers a 15-year product warranty (materials and workmanship) and a 25-year linear power warranty for this series. After 25 years, the module is guaranteed to retain at least 89.4% of its rated output. Annual power degradation from year 2 onward is below 0.4%, which outperforms most legacy PERC modules on the market. ### What is HPBC technology in the Hi-MO X6 Explorer series and why does it matter? HPBC (Hybrid Passivated Back Contact) moves all electrode contacts to the rear side of the cell, eliminating front-side busbar shading losses. More light is converted into electricity and resistive losses are reduced. In practice, this means steadier power output on sunny days and smaller performance dips under partial shading or elevated operating temperatures — benefits that directly increase annual energy yield. ### Do the Longi Hi-MO X6 Explorer LR7-54HTH 465M panels lose much power on hot summer days? Thanks to the N-type HPBC cell, the temperature coefficient is just -0.28%/°C — among the lowest in this power class. Conventional PERC panels typically lose around -0.35%/°C. At a module temperature of 65°C (common in a Central European summer), the Hi-MO X6 Explorer loses roughly 11% of rated power versus around 14% for PERC, resulting in meaningfully higher daily energy output. ### What is the efficiency of the Longi Hi-MO X6 Explorer LR7-54HTH panels, and how much roof space does a 10 kWp system need? The modules achieve 22.3%–22.8% efficiency at dimensions of 1800×1134×30 mm and a weight of 21.6 kg. A 10 kWp system using 465 W panels requires 22 modules, covering approximately 44–46 m² of roof area. That is less space than older PERC modules of similar power, which is a clear advantage when usable roof area is limited. ### Are the Longi Hi-MO X6 Explorer LR7-54HTH panels suitable for a gable roof with chimneys or dormers? Yes, this is a strong fit for such conditions. The half-cut cell layout (108 cells) splits each module into two independent electrical halves, so a shadow cast by a chimney or dormer affects only the shaded portion while the rest continues operating at full output. The 21.6 kg weight also makes handling and installation on standard rafter structures straightforward. ### Is the Longi Hi-MO X6 Explorer LR7-54HTH 455~465M series still available for purchase? Yes, the series is actively manufactured and available through distribution channels. Longi Solar is a Tier 1 manufacturer headquartered in China with a well-established logistics network across Europe. Continued production availability means installers and homeowners can easily add more modules to expand an existing system without compatibility concerns. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/lr-7-54-hth-455-465-m-30-30-and-15-frame-explorer-20240511-v-36f2bde26491.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +45 W, +2.2 pp, +5 yr warranty | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +30 W, +2.0 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, +1.9 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +25 W, +1.7 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, +1.7 pp, +5 yr warranty | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +35 W, +1.7 pp, +5 yr warranty | | [Longi Solar LR7-54HGBB-440M](https://comparepv.com/panel/longi-lr7-54hgbb-440m) | 440 W | -25 W, -1.2 pp, +5 yr warranty | | [Longi Solar LR7-54HGBB-445M](https://comparepv.com/panel/longi-lr7-54hgbb-445m) | 445 W | -20 W, -1.0 pp, +5 yr warranty | | [Longi Solar LR7-54HGBB-450M](https://comparepv.com/panel/longi-lr7-54hgbb-450m) | 450 W | Heavier, -0.8 pp, +5 yr warranty | | [Longi Solar LR7-54HTH-455M](https://comparepv.com/panel/longi-lr7-54hth-455m) | 455 W | -10 W, -0.5 pp | | [Longi Solar LR7-54HTH-460M](https://comparepv.com/panel/longi-lr7-54hth-460m) | 460 W | -0.3 pp | --- Source: https://comparepv.com/panel/longi-lr7-54hth-465m 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.
