This translates into lower production losses on hot days and higher summer energy yield. - **30-year power warranty with 87.4% retention** - The manufacturer guarantees at least 87.4% of nominal power retained after 30 years, backed by a 25-year product warranty - a level comparable to leading TOPCon offerings and notably longer than the standard 25-year warranties common on older-generation PERC modules. - **High mechanical durability per TUV Nord** - The module has passed TUV Nord certification with a wind load rating of 2400 Pa and a snow load rating of 5400 Pa - a significant advantage for installations in regions with heavy snowfall or strong winds. - **Higher efficiency than some peer series** - The maximum efficiency of 22.55% exceeds comparable series Silfab SIL HM (21%) and Lina Energy LEPV 132 HC ICON PLUS (21.06%) at the same 500 Wp maximum power, meaning a smaller installation footprint for the same system capacity. - **Tier-1 manufacturer with BNEF bankability rating** - Leapton holds Tier 1 BNEF status, confirming supply to at least 6 projects financed by different non-recourse project finance banks - a key factor for commercial installations seeking bank financing. ## Cons - **Lower efficiency than select competitors** - The maximum efficiency of 22.55% is noticeably lower than the Gokin GK-3-54HGF series, which reaches 24.5% at the same 500 Wp power rating - for roof-constrained projects this may mean choosing a pricier alternative. - **No bifacial variant in this series** - The LP182\*182-M-60-NH series is monofacial, while some competing tier-1 designs (e.g., HM/bifacial constructions) offer an additional 5-15% yield from the rear side - a potential limitation for installations on reflective surfaces or ground-mount systems. ## About this series The Leapton LP182\*182-M-60-NH series comprises modules based on **N-type cells in TOPCon technology**, designed to deliver stable performance under real-world conditions, even in partially shaded areas and with fluctuating weather. The use of half-cut cell architecture and multi-busbar connections supports **lower internal losses and improved performance at high temperatures**, which translates to more predictable energy production during the summer months. In practice, this series helps address common investor concerns: power drops during hot weather, sensitivity to reduced sunlight, and the risk of long-term degradation. The modules offer **positive power tolerance**, and the design and material selection are focused on long-term operation - crucial for installations that are intended to operate autonomously for years. Leapton LP182\*182-M-60-NH is well-suited for premium residential installations, commercial rooftop systems, and projects where **long-term warranty and high operational durability** are paramount - without compromising on quality, as is often seen in cheaper alternatives. ## Notable figures - Module efficiency of 21.2% is 1.3pp below average for \*\*TOPCon 450-500W\*\* panels (median: 22.5%) - At 212.5 W/m², this panel generates 12.7 W/m² less per unit area than \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 450-500W\*\* median - Weight of 23.0 kg is typical for \*\*TOPCon 450-500W\*\* panels - Ranked #8904 out of 14005 panels for efficiency in the database ## Questions ### What is TOPCon technology and why does the Leapton LP182\*182-M-60-NH series use it? TOPCon (Tunnel Oxide Passivated Contact) is an N-type silicon cell architecture that minimizes recombination losses at the contact interface. This allows the LP182\*182-M-60-NH to reach up to 22.55% efficiency — noticeably higher than typical PERC modules. In practice, it means more energy from the same roof area, better low-light performance, and slower long-term degradation compared to older P-type technology. ### What warranty does the Leapton LP182\*182-M-60-NH series come with? The LP182\*182-M-60-NH includes a 25-year product warranty covering mechanical integrity and a 30-year power output warranty. After 30 years, modules are guaranteed to retain at least 87.4% of rated power, equating to roughly 0.4% annual degradation. These terms exceed the standard 25/25-year coverage offered by many competitors and reflect Leapton's Tier 1 manufacturer status. ### How do the LP182\*182-M-60-NH panels perform in summer heat and high temperatures? The temperature coefficient of Pmax is -0.30%/°C, among the lowest in its class. Compared to typical PERC modules rated at -0.35%/°C or worse, these panels lose less power on hot days. At a cell temperature of 70°C, the LP182\*182-M-60-NH loses roughly 13.5% of rated power versus about 15.75% for standard PERC — a measurable difference in annual energy yield. ### Do the LP182\*182-M-60-NH panels handle partial shading from a chimney or dormers well? Yes. The modules use a 120-cell half-cut layout that divides the panel into two electrically independent halves. Shade cast by a chimney, dormer, or antenna limits only part of the module's output instead of throttling the whole panel. Combined with N-type TOPCon cells and multi-busbar interconnects, this gives the series a clear advantage over older technologies on rooftops with obstructions. ### What are the dimensions and weight of the Leapton LP182\*182-M-60-NH — will they fit on a small roof? Each module measures 1955 × 1134 × 30 mm and weighs 23.5 kg — a standard footprint for 500 Wp panels. On a typical pitched roof with around 30 m² of usable surface, you can fit 10 to 12 modules (5–6 kWp), depending on roof geometry and required clearances from eaves and ridge. The per-unit weight is manageable for standard rafter construction. ### What mechanical load rating do the Leapton LP182\*182-M-60-NH panels carry — can they handle heavy snow? The LP182\*182-M-60-NH is TÜV Nord certified for a snow load of 5,400 Pa and a wind load of 2,400 Pa. In Polish climate conditions — including heavy wet snowfall — these ratings are sufficient for the vast majority of standard pitched-roof installations when mounted on a certified racking system. The certification covers both static and dynamic load scenarios. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/a51b46b9255ef3e37f9a7c9fcd6fc249-25cb147392e3.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +50 W, cooler, +3.8 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +35 W, cooler, +3.6 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +45 W, cooler, +3.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +30 W, cooler, +3.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +40 W, cooler, +3.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +40 W, cooler, +3.2 pp | | [Leapton LP182\*182-M-60-MH-450W](https://comparepv.com/panel/leapton-lp182-182-m-60-mh-450w) | 450 W | Hotter, -0.5 pp, -5 yr warranty | | [Leapton LP182\*182-M-60-MH-455W](https://comparepv.com/panel/leapton-lp182-182-m-60-mh-455w) | 455 W | Hotter, -0.2 pp, -5 yr warranty | | [Leapton LP182\*182-M-60-MH-465W](https://comparepv.com/panel/leapton-lp182-182-m-60-mh-465w) | 465 W | Hotter, +0.2 pp, -5 yr warranty | | [Leapton LP182\*182-M-60-NB-470W](https://comparepv.com/panel/leapton-lp182-182-m-60-nb-470w) | 470 W | +10 W, heavier, +0.5 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +100 W, cooler, +3.6 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +95 W, cooler, +3.4 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +90 W, lighter, +3.1 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +80 W, cooler, +3.1 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +80 W, cooler, +3.1 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +85 W, heavier, +3.0 pp | --- Source: https://comparepv.com/panel/leapton-lp182-182-m-60-nh-460w 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.
