The Leapton LP182*182-M-60-NB series are N-type bifacial modules in a half-cut format, designed to maximize energy output from the same installation area - especially when conditions are not ideal. Thanks to N-type cells (often associated with TOPCon technology), these panels offer improved performance in low-light conditions and slower degradation of parameters over time, which translates to more stable production in the Polish climate.

The dual glass construction enhances durability and resistance to harsh environments, while the bidirectional energy harvesting allows for the utilization of reflected light - which is important on bright roofs, gravel, membranes, or when mounted on the ground. The use of multi-busbar cells (MBB) helps to reduce losses and improve reliability in partially shaded conditions.

This is a good choice for investors who want higher annual yields without increasing service risks - from single-family homes to small and medium-sized commercial installations.

What owners get
N-type TOPCon cell technology

N-type TOPCon cells exhibit lower LID/LeTID degradation and better performance at elevated temperatures and low irradiance than older PERC cells, translating into a real annual yield uplift under Polish climate conditions.

Bifacial dual-glass construction

Two-sided energy harvesting combined with a glass-glass enclosure captures albedo reflected light (up to several extra percentage points of yield over bright ground surfaces) while also improving mechanical durability compared to glass-backsheet designs.

30-year power warranty at 87.4%

The manufacturer guarantees at least 87.4% of nominal power after 30 years, exceeding the industry-standard 25-year/80.7% benchmark and outperforming warranty terms offered by many PERC-based panels in this power class.

BNEF Tier-1 status

Leapton is listed on BloombergNEF's Tier-1 manufacturer list (Q1 2026), which eases bank and leasing financing for projects and signals financial stability and production scale.

Half-cut cells with multi-busbar (MBB)

The half-cut design with multi-busbar (MBB) technology reduces resistive losses and improves reliability under partial shading, relevant for irregular installation conditions such as chimneys, antennas, or nearby trees.

Trade-offs
Efficiency below segment leaders

The series' maximum efficiency (22.17%) trails competing modules at the same 480 Wp power class, such as the Gamko GKA96N-PRO (24.02%) and Sunket SKT460~480M10-120D3 (22.24%). This means a slightly larger module area is needed to reach the same power output, which may matter on roofs with limited surface area.

Notes from the database
  • At 21.9% efficiency, this panel is 0.6pp below the TOPCon 450-500W median of 22.5%
  • At 219.4 W/m², this panel generates 5.8 W/m² less per unit area than TOPCon 450-500W median (225.2 W/m²)
  • At -0.30%/°C, hot weather performance is typical for TOPCon 450-500W panels
  • At 26.5 kg, this panel is 2.5 kg heavier than the TOPCon 450-500W median (24.0 kg) - more demanding for installation crews
  • Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface

Common questions

6 answered
How does the Leapton LP182*182-M-60-NB perform in low-light conditions and cold temperatures?
The N-type TOPCon cell technology delivers better output in overcast and diffuse-light conditions compared to older PERC modules. The power temperature coefficient is -0.30%/°C, meaning lower losses on hot days. For the Polish climate with frequent cloudy periods, this translates into measurably higher annual energy yield versus previous-generation panels.
What warranties does the Leapton LP182*182-M-60-NB series carry?
The manufacturer provides a 25-year product warranty covering manufacturing defects and a 30-year power warranty guaranteeing at least 87.4% of rated output. Annual degradation for N-type cells is approximately 0.4%, significantly better than the typical 0.55% for PERC modules, resulting in more stable production over the full system lifetime.
What real benefit does the bifacial design of the LP182*182-M-60-NB offer, and when does it pay off?
The bifacial dual glass construction captures an additional 5–25% of energy from light reflected off the ground or roof surface. Gains are highest for ground-mounted systems, light-colored roofing membranes, and gravel substrates. On a typical dark roof tile the bifacial gain will be lower — this should be factored into yield calculations before purchase.
Can the Leapton LP182*182-M-60-NB be installed on a standard pitched roof?
Yes. The module measures 1909 × 1134 × 30 mm and weighs 26.5 kg. Wind load resistance of 2400 Pa and snow load capacity of 5400 Pa (TÜV Nord certified) are adequate for Central European climate conditions. The dual glass construction is heavier than standard foil-backed modules — verifying the roof's structural load capacity is recommended, especially on older buildings.
Is Leapton a Tier 1 manufacturer, and is the warranty secure?
Leapton Solar is rated Tier 1 by leading PV industry agencies and is headquartered in Japan with its own production facilities, which supports standardized warranty procedures. To ensure warranty claims are handled efficiently, confirm that your local distributor holds an active service agreement with the manufacturer before purchasing.
Is the LP182*182-M-60-NB series suited for residential homes or commercial installations?
At 480 Wp peak power, this series works well in residential prosumer systems (e.g., 10–20 kWp) as well as small and mid-size commercial installations. The half-cut layout with 120 cells using 182 mm wafers improves energy yield under partial shading — particularly useful wherever the roof or ground array is subject to shadows from chimneys, dormers, or adjacent structures.
