The Leapton LP182*210-M-48-NH module series redefines performance standards through the use of innovative N-type cells, which feature near-zero initial degradation and excellent efficiency in low-light conditions. The use of a unique silicon wafer format combining the advantages of 182 mm and 210 mm standards has achieved an optimal balance between power and physical dimensions. A key differentiator is SMBB technology (Super Multi-Busbar), which minimizes the risk of micro-cracks and improves current flow, translating into long-term energy stability. The design based on 48 cells makes the panels lighter and easier to install, solving the problem of excessive load on roof structures while maintaining very high yields. Thanks to a high bifaciality factor, these modules are ideal for ground-mounted and commercial installations, where reflected light generates additional energy gain. Unlike the competition, this series offers a better temperature coefficient, which guarantees stable operation even on hot days. This solution is dedicated to prosumers seeking maximum return on investment and professional installers who value ergonomics and the reliability of premium-class components in modern photovoltaics.

What owners get
N-type TOPCon cells with low degradation

TOPCon technology delivers near-zero initial light-induced degradation (LID) and better high-temperature performance than older PERC cells, translating into higher real-world annual energy yield.

Up to 22.77% efficiency, top of segment

Maximum efficiency of 22.77% matches LEDVANCE's M435~455N54LB-SF-F7 and is nearly on par with Sunlike Solar's SKT420~455M10-108D6 (22.8%), placing the series among the leading 435-455 Wp comparables.

Extended 25/30-year product and power warranty

The manufacturer offers a 25-year product warranty and a 30-year linear power warranty - longer performance coverage than the standard 25-year power warranties offered by many tier-1 competitors.

Lightweight 48-cell design

The 48-cell configuration combining 182 mm and 210 mm wafer formats reduces module weight and dimensions versus conventional 54/60-cell panels, easing installation and reducing roof structural load.

Tier-1, bankable manufacturer

Leapton (Japan, founded 2012) is a tier-1 manufacturer recognized by project financiers, which facilitates bank financing for installations based on this series.

Trade-offs
No bifacial variant available

About the LP182*210-M-48-NH series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What warranty does the Leapton LP182*210-M-48-NH come with and what does it cover?
The LP182*210-M-48-NH series carries a 25-year product warranty covering material and workmanship defects, plus a 30-year power output warranty guaranteeing at least 87.4% of rated capacity at year 30. Leapton is a Tier 1 manufacturer, meaning the company has the financial stability to back these warranty claims over the full 30-year period.
What is TOPCon technology and why does it matter for the LP182*210-M-48-NH?
TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that uses a thin tunnel oxide layer to drastically reduce carrier recombination. For the LP182*210-M-48-NH, this translates to initial degradation below 1% in year one (versus 2-3% for standard PERC cells), superior low-light performance, and better thermal stability. The result is up to 455 Wp output in a compact 48-cell layout with a longer productive lifespan.
Is the Leapton LP182*210-M-48-NH suitable for residential sloped-roof installations?
Yes. The 48-cell layout makes this module physically smaller and lighter (approx. 24 kg) than most 60- or 72-cell alternatives at similar wattage, simplifying transport across the roof surface and installation on standard racking systems. The SMBB busbar design also improves resistance to microcracks that can develop during handling and mounting, making it a practical choice for residential installers working on pitched roofs.
How does the LP182*210-M-48-NH perform during summer when cell temperatures exceed 50°C?
The N-type TOPCon cells in the LP182*210-M-48-NH deliver a temperature coefficient of approximately -0.30%/°C, which is notably better than the -0.35%/°C typical of PERC modules. For every 10°C rise in cell temperature above 25°C, power loss is about 0.5 percentage points lower than with PERC. In real conditions where summer cell temperatures reach 60-70°C, this advantage compounds into measurably higher energy yield over the peak season.
How does the 182×210 mm cell format in the LP182*210-M-48-NH differ from standard M10 or G12 wafers?
The LP182*210-M-48-NH uses a hybrid wafer format that blends the M10 (182 mm) and G12 (210 mm) standards. This allows a high module wattage to be achieved with only 48 cells, keeping physical dimensions manageable for rooftop installations. Full G12 panels deliver more power per module but are heavier and harder to handle on residential rooftops. The 182×210 mm hybrid is an engineering compromise: high output without the structural load penalty of full G12 form factors.
Is Leapton a reliable manufacturer and is the LP182*210-M-48-NH still in production?
Leapton Energy is headquartered in Japan and is recognized as a Tier 1 solar module manufacturer by independent industry analysts, confirming consistent production quality and financial strength necessary to honor long-term warranties. The LP182*210-M-48-NH series is currently active and available, not discontinued, which is an important consideration given the 30-year power warranty tied to the manufacturer's ongoing viability.
