Half-cut TOPCon technology reduces LID losses and improves high-temperature performance compared to legacy PERC structures. - **Bifacial glass-glass construction** - Double-sided cells in a glass-glass layout capture light reflected off the ground surface, boosting real-world energy yield in both rooftop and utility-scale installations, while also improving mechanical durability versus glass-backsheet designs. - **30-year power warranty with high retention threshold** - The manufacturer guarantees at least 87.4% of nominal power after 30 years, alongside a 25-year product warranty - better than the segment's common 25-year product / 25-30-year power standard with degradation to ~84.8%. This translates into lower LCOE over the system's full operating lifetime. - **Tier-1 status per BloombergNEF** - Leapton (founded 2012, HQ in Japan) appears on BloombergNEF's Tier-1 list, meeting bankability criteria required by project financiers, and the series also received a Top Performer rating in the 2025 Kiwa PVEL PV Module Reliability Scorecard. - **Aesthetic all-black module design** - The black frame and uniform appearance fit well in installations where building aesthetics matter, such as single-family homes with visible roof areas. ## Cons - **Comparatively small production scale** - Despite Tier-1 status, Leapton has a relatively modest annual manufacturing capacity (around 2.15 GW after expansion), far smaller than segment giants like JA Solar, Trina, or LONGi with tens of GW. This may mean less flexibility for large orders and a potentially weaker service network in some regions. - **Manufactured in China despite Japanese branding** - While Leapton is headquartered in Kobe, Japan, the modules are physically manufactured at a factory in Changshu, China. Buyers expecting Japanese-made production should be aware of this when assessing the brand's premium positioning. ## About this series The **Leapton LP182\*210-M-48-NB** series is a photovoltaic module lineup designed for anyone who wants to make the most of every square meter of available mounting space. The panels are built on **n-type TOPCon cells** using half-cut technology, which translates into more stable electrical parameters and lower losses under partial shading compared to classic PERC structures. The **bifacial glass-glass construction** captures light reflected off the ground, boosting real-world energy yield both on residential rooftops and in large-scale installations. The black frame and clean module appearance make this series well suited to projects where the building's visual appeal also matters. High resistance to mechanical loads, confirmed by wind and snow load testing, makes these panels a good fit for demanding climates, including regions with heavy snowfall. Thanks to long service life and stable power degradation over time, investors can count on a lower levelized cost of energy (LCOE) across the entire lifespan of the installation. The LP182\*210-M-48-NB series is a solution for installers and investors looking for a balance between performance, durability, and aesthetics in a single module. ## Notable figures - At 22.3% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - Power density of 222.7 W/m² matches the \*\*TOPCon 400-450W\*\* median - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 400-450W\*\* median - At 24.0 kg (2.0 kg above \*\*TOPCon 400-450W\*\* median of 22.0 kg), requires checking roof load capacity - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof ## Questions ### How does the TOPCon cell technology used in Leapton LP182\*210-M-48-NB panels differ from classic PERC cells? N-type TOPCon cells feature an additional passivation layer that reduces electron recombination, delivering higher efficiency than p-type PERC. In practice this means a smaller power drop at high temperatures and more stable electrical parameters over the panel's lifetime. Thanks to the half-cut cell structure, these panels also handle partial shading better, resulting in higher and more predictable energy yield. ### Is it worth installing bifacial Leapton LP182\*210-M-48-NB panels on a single-family home roof? Yes, though the biggest gain from bifacial technology appears with light-colored surfaces or ground-mounted structures where light reflects off the background. On a typical pitched roof the rear-side gain is smaller but still measurable, especially with light-colored tiles or metal roofing. The glass-glass construction also boosts mechanical durability, a benefit independent of how much bifacial gain is realized. ### What warranty applies to Leapton LP182\*210-M-48-NB panels and what does it cover? The manufacturer provides a 25-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. This means that after 30 years the panel should still deliver the guaranteed percentage of its initial rated power per the datasheet. This warranty level is typical of Tier 1 manufacturers and gives investors greater confidence in the long-term LCOE of the installation. ### Is 460 Wp enough power from Leapton LP182\*210-M-48-NB panels for a roof with limited space? A 460 Wp half-cut TOPCon module is among the higher-power panels available in its size class, allowing more kilowatts to be installed with fewer panels. For a typical 10 kWp system, around 22 panels are needed, which meaningfully reduces the required roof area compared to older 350-400 Wp modules. ### Will Leapton LP182\*210-M-48-NB panels hold up in regions with heavy snowfall? Yes, the glass-glass construction and black frame have been tested for mechanical load resistance, including snow and wind loads, per industry standards. The stiffer double-glass build also improves resistance to deflection and microcracks under heavy winter loads, making this series a solid choice for harsher climates. ### Who manufactures Leapton panels, and is it a reliable choice for a 25-30 year investment? Leapton operates in the PV market with technological roots tied to Japan and is classified as a Tier 1 manufacturer, indicating financial stability and a proven production line. This status matters for long-term warranties (25-year product, 30-year power), as it lowers the risk of the company disappearing from the market before the warranty period expires. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/622-379ca1cd9635.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +50 W, cooler, +2.5 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +45 W, cooler, +2.2 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +45 W, cooler, +2.2 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +40 W, lighter, +2.0 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +40 W, cooler, +2.0 pp | | [Longi Solar LR7-54HJD-495M](https://comparepv.com/panel/longi-lr7-54hjd-495m) | 495 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +40 W, cooler, +2.0 pp | | [Leapton LP182\*182-M-54-NH-430W](https://comparepv.com/panel/leapton-lp182-182-m-54-nh-430w) | 430 W | -15 W, lighter, -0.8 pp | | [Leapton LP182\*182-M-54-NB-435W](https://comparepv.com/panel/leapton-lp182-182-m-54-nb-435w) | 435 W | -10 W, heavier, -0.5 pp | | [Leapton LP182\*210-M-48-NB-440W](https://comparepv.com/panel/leapton-lp182-210-m-48-nb-440w) | 440 W | -0.2 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +65 W, cooler, +2.7 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +60 W, cooler, +2.4 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +60 W, cooler, +2.4 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +55 W, cooler, +2.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/leapton-lp182-210-m-48-nb-445w 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.
