The Leapton LP182*182-M-60-NB (N-Type Double Glass) series are modules designed for maximum energy yield in environments where reliability and stable performance over many years are crucial. The use of N-type cells in MBB technology minimizes internal losses and improves performance under partial shading, which effectively helps maintain production in typical Polish roof and ground-mounted conditions.

A key advantage is the double-sided (bifacial) glass-to-glass construction - the panel can also utilize reflected light from the ground, which increases profitability, for example, on bright roofs, on the ground, on elevated structures, and in carports. The glass on both sides also provides higher resistance to moisture and environmental factors, and additional PID-resistant features support long-term power stability.

This is a good choice for installers and investors who are looking for modules that stand out for their durability, better performance in low light conditions, and greater tolerance to harsh working conditions.

What owners get
N-type cells with MBB technology

N-type cells in a multi-busbar (MBB) configuration reduce resistive losses and improve performance under low-irradiance and partial-shading conditions, translating into higher annual energy yield compared to conventional PERC modules.

Bifacial glass-glass construction

The bifacial glass-glass design captures light reflected from the ground surface, boosting output by an estimated 5-25% depending on albedo - a real advantage for installations on light-colored roofs, ground mounts, and carports.

High mechanical durability

TÜV Nord-tested to withstand wind loads up to 2400 Pa and snow loads up to 5400 Pa, providing a safety margin that matters for demanding climate conditions, including roofs exposed to heavy snowfall.

30-year linear power warranty with low degradation

The manufacturer specifies an average annual degradation rate of just 0.4%, alongside a 30-year linear power warranty and 25-year product warranty - placing this series ahead of the standard 25/25-year terms offered by many competitors in the premium N-type segment.

Independently validated reliability via PVEL

Leapton Solar was recognized as a Top Performer in Kiwa PVEL's 2025 PV Module Reliability Scorecard, providing independent confirmation of the durability of the technology used in this series.

Trade-offs
Efficiency trails top-tier competitors

The 22.55% maximum efficiency lags behind comparable models such as the Gokin GK-3-54HGF (24.5%) and Selfa SV120M.2.4 (22.6%) at the same 500 Wp power class, meaning a slightly larger installation area is needed for equivalent energy output.

Notes from the database
  • At 22.1% efficiency, this panel is on par with typical N-type 450-500W modules
  • 221.0 W/m² power density is 4.2 W/m² below N-type 450-500W median (225.2 W/m²) - requires larger installation area
  • At -0.30%/°C, hot weather performance is typical for N-type 450-500W panels
  • Weight of 27.0 kg is 3.3 kg above N-type 450-500W median (23.7 kg) - verify structural support

Common questions

6 answered
What warranty does the Leapton LP182*182-M-60-NB series come with and what does it cover?
The LP182*182-M-60-NB series includes a 25-year product warranty and a 30-year linear power warranty. In year one, at least 99% of rated output is guaranteed, and after 30 years the module retains a minimum of 87.4% of its nominal power. Leapton is a Tier 1 manufacturer headquartered in Japan, which adds confidence that warranty claims will be honored throughout the panel's service life.
Do the Leapton LP182*182-M-60-NB panels perform well in winter and on overcast days typical of Central European climates?
Yes. The temperature coefficient of Pmax is -0.3%/°C, one of the best figures in this module class. N-type TOPCon cells exhibit low LID and superior low-irradiance efficiency compared to P-type PERC. In Poland, where a significant share of annual yield comes from diffuse-light days, this advantage results in a measurable increase in total annual energy production.
When does the bifacial design of the LP182*182-M-60-NB actually deliver a meaningful yield gain?
The bifacial design captures reflected irradiance from the rear side, adding 5–25% in additional yield depending on ground albedo. Gains are highest on ground-mount systems, carports, elevated racking structures, and roofs with bright gravel or white membranes beneath the array. On a conventional pitched roof with dark tiles, rear-side contribution is minimal, so the bifacial advantage is best exploited in open-field installations.
Can the LP182*182-M-60-NB modules handle heavy snow and strong wind loads on Central European rooftops?
Yes. The double-glass construction has been TÜV Nord certified for a snow load of 5400 Pa (approximately 550 kg/m²) and a wind load of 2400 Pa, both exceeding standard requirements for most locations in Poland. The glass-glass encapsulation also provides significantly better moisture resistance and mechanical integrity compared to glass-backsheet modules.
What is the practical difference between N-type TOPCon and standard P-type PERC cells, and why does it matter for the system owner?
N-type TOPCon cells in the LP182*182-M-60-NB series reach efficiency up to 22.55% and exhibit substantially lower LID than P-type PERC. This means more kilowatt-hours per square meter of roof space over the full system lifetime. Combined with the 30-year power warranty, the resulting LCOE of an installation built on this series is typically lower than equivalent capacity using conventional P-type modules.
What are the dimensions and weight of the Leapton LP182*182-M-60-NB panel, and will it fit on a standard pitched roof?
The module measures 1955 × 1134 × 30 mm and weighs 27 kg. This is a standard 60-cell format using 182 mm half-cut cells. A 30 m² south-facing pitched roof can accommodate approximately 14–16 panels. The weight is compatible with standard aluminum racking systems, though for systems above 10 kW it is advisable to verify roof load capacity with a structural engineer.
