Solid all-round for its segment
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.
Ranking
Signals from the data
Residential, commercial, shaded-installations and cold-climate.
Module efficiency up to 23.02% puts the series on par with the best peer comparables (Phono Solar Draco, SunKean SKT440~460M12-96D4), outperforming e.g. Axitec AXIbiperfect GR WB (22.54%). Half-cut TOPCon technology reduces LID losses and improves high-temperature performance compared to legacy PERC structures.
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.
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.
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.
The black frame and uniform appearance fit well in installations where building aesthetics matter, such as single-family homes with visible roof areas.
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.
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.
- 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
