**High mechanical load rating of 5400 Pa/2400 Pa** - The dual-glass construction, verified through TÜV Nord testing, withstands snow loads up to 5400 Pa and wind loads up to 2400 Pa, matching or exceeding typical aluminum-frame module ratings and giving an edge in regions with heavy snowfall. - **30-year linear power warranty** - The manufacturer offers a 30-year power warranty and a 25-year product warranty, matching leading market offerings (e.g., Jinko Tiger Neo, Canadian Solar TOPBiHiKu6) and exceeding the standard 25/12-year terms found among many Tier-2 manufacturers. - **N-type TOPCon technology with low LID/LeTID degradation** - N-type cells reduce the typical aging losses (LID/LeTID) characteristic of older P-type PERC cells, resulting in more predictable energy yield over a 25-30 year operating lifetime. - **Bifacial dual-glass design boosting energy yield** - The dual-glass construction with bifacial cells captures light reflected from the ground surface, meaningfully increasing energy production in ground-mounted installations and on light-colored roofs, particularly with greater ground clearance. - **BNEF Tier-1 status and Japanese technology origin** - Leapton holds Tier-1 status according to BloombergNEF (Q1 2026 update), confirming module use in at least six projects financed by different non-recourse project finance banks - an important factor for bank-financed investments. ## Cons - **Efficiency trails top-tier competitors** - Efficiency of 22.18-22.54% is notably lower than comparable series at the same 630 Wp power class - Canadian Solar TOPBiHiKu6 Anti-Dust (23.3%), Resun RS8H-M-BD (23.32%), and Jinko Tiger Neo 66HL4M-BDV (23.32%) - a gap of roughly 0.8-1.1 percentage points meaning lower yield from the same roof area. ## About this series The Leapton LP182\*199-M-72-NB series are **N-type TOPCon** modules with a **dual glass** construction, designed for stable energy production over many years - even in challenging operating conditions. The bidirectional architecture allows for better utilization of light reflected from the ground, which effectively supports yields in ground-mounted installations, on bright roofs, and in systems with larger ground clearance. The use of N-type cells helps to minimize typical aging losses, while the TOPCon technology improves the module's performance at high temperatures and in variable sunlight conditions, which is important in the Polish climate. A key feature is the **enhanced mechanical strength** resulting from the glass-glass construction, which is important under heavy snow and wind loads. The modules are also designed with a focus on **PID resistance** and operation in corrosive environments (salty mist, ammonia), making them well-suited for use near industrial areas, farms, and coastal areas. This is a choice for investors who expect **long-term yield predictability** and a robust construction, rather than just high power on paper. ## Notable figures - Efficiency of 22.4% matches the \*\*TOPCon 600-650W\*\* median - Power density of 223.6 W/m² is 4.1 W/m² below \*\*TOPCon 600-650W\*\* median (227.7 W/m²) - needs more roof space - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 600-650W\*\* median - Weight of 34.3 kg is 1.6 kg above \*\*TOPCon 600-650W\*\* median (32.7 kg) - verify structural support - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### What warranty comes with the Leapton LP182\*199-M-72-NB modules? The LP182\*199-M-72-NB series carries a 25-year product warranty covering materials and workmanship, plus a 30-year power output warranty. After 30 years, the manufacturer guarantees at least 87.4% of nominal power. First-year degradation is capped at 1%, which is standard for N-type TOPCon cells and better than conventional PERC modules. ### What does bifacial design actually mean for the LP182\*199-M-72-NB, and when does it pay off? Bifacial modules capture light reflected off the ground or rooftop surface through the rear glass, delivering 5–25% additional energy depending on surface albedo. You'll see the best gains in ground-mount systems with bright substrates, on white TPO or PVC roofing membranes, or wherever panels are elevated well above the surface. On a dark roof with no clearance, the bifacial gain is negligible. ### Can the LP182\*199-M-72-NB modules handle heavy snow loads typical in Central Europe? Yes. The dual glass construction — two 2.0 mm tempered glass panes — gives the module a certified snow load rating of 5,400 Pa and a wind load rating of 2,400 Pa, both well above what standard backsheet modules offer. The glass-glass build also eliminates backsheet bubbling and reduces the risk of micro-cracks during temperature cycling. ### How do the N-type TOPCon cells in the LP182\*199-M-72-NB compare to PERC modules? N-type TOPCon cells have a lower temperature coefficient (−0.30%/°C vs. roughly −0.35% for PERC), which means less power loss on hot days. They are also far less prone to LID and LeTID degradation. Over a 30-year lifespan, a TOPCon module with the same nameplate wattage will generate more total energy than a comparable PERC panel. ### Are the Leapton LP182\*199-M-72-NB modules suitable for coastal or industrial environments? Yes. The NB series is tested for salt spray and ammonia corrosion resistance, making it a solid choice for coastal installations and sites near chemical plants or large livestock facilities. The sealed dual glass structure also provides superior moisture barrier compared to standard backsheet modules, reducing the risk of cell corrosion over time. ### How heavy is the LP182\*199-M-72-NB module and will a standard roof structure support it? Each module weighs approximately 35.3 kg and measures 2465 × 1134 × 30 mm. That is significantly heavier than lightweight backsheet modules at 20–23 kg. For sloped roof installations, especially older buildings, a structural engineer should verify roof load capacity before installation. Ground-mount and flat-roof ballasted systems generally have no issue with the added weight. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/99e5d35bb7bbd8117bad6d94269f3b90-116dc0618529.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +2.8 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +50 W, lighter, +2.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +2.6 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +45 W, lighter, +2.4 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +45 W, lighter, +2.4 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +2.4 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, cooler, +2.4 pp | | [Leapton LP182\*182-M-78-NH-610W](https://comparepv.com/panel/leapton-lp182-182-m-78-nh-610w) | 610 W | -15 W, lighter, -0.5 pp | | [Leapton LP182\*182-M-78-NH-615W](https://comparepv.com/panel/leapton-lp182-182-m-78-nh-615w) | 615 W | -10 W, lighter, -0.4 pp | | [Leapton LP182\*199-M-72-NH-620W](https://comparepv.com/panel/leapton-lp182-199-m-72-nh-620w) | 620 W | Lighter | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +55 W, lighter, +2.8 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +75 W, cooler, +2.6 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +70 W, cooler, +2.5 pp | --- Source: https://comparepv.com/panel/leapton-lp182-199-m-72-nb-625w 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.
