The Leapton LP182*182-M-78-NB series are N-type TOPCon modules with a dual-glass design and bidirectional energy generation, designed for installations where stable production over a long period is crucial. Thanks to the N-type technology, the panel better handles typical operating losses and maintains high efficiency even in warmer conditions, which significantly improves the profitability of the investment in Polish conditions.

The dual-glass design increases resistance to environmental factors and makes it easier to maintain performance over time, while bifaciality allows for "collecting" additional reflected radiation from a bright surface - especially on industrial roofs, carports, PV farms, and structures with high albedo. This is a good choice for projects that aim to maximize energy yield from a limited area and reduce the risk of power drops. In practice, it stands out due to its combination of high reliability and predictable, long-term performance, which is often difficult to achieve in standard unidirectional modules.

What owners get
N-type TOPCon cell technology

N-type TOPCon cells deliver lower LID/LeTID degradation and better high-temperature performance (Pmax temperature coefficient of -0.3%/°C) compared to older PERC cells, translating into higher real-world annual yield, especially in summer.

Dual-glass bifacial construction

The dual-glass build with 3.2 mm glass thickness improves mechanical and chemical durability, while bifaciality captures additional reflected irradiance from the ground - a strong advantage on industrial rooftops, carports, and ground-mount structures with high albedo.

Long, linear 30-year power warranty

The manufacturer guarantees 99% power after year one and 87.4% after 30 years - longer than the standard 25-year warranties offered by many competitors, improving LCOE predictability over the project lifetime.

BNEF Tier-1 status and track record since 2012

Leapton Solar holds a BloombergNEF Tier-1 bankability classification and has operated since 2012 out of Japan, reducing financing risk for projects built on this series.

High per-module power output

Power output up to 625 Wp across 156 cells and a 2465×1134 mm footprint reduces the module count needed to reach a target system size, lowering BoS costs (racking, wiring, labor).

Trade-offs
Lower efficiency than segment leaders

Efficiency of 21.82-22.36% trails comparable 625 Wp-class modules such as Longi Hi-MO 7 (23.1%) and DAH Solar DHN-66Z16/DG and DHN-72R20/DG (23.14%) - a gap of roughly 1.3 pp means lower yield from the same roof area.

Limited manufacturing scale

Leapton's annual production capacity (around 660 MW ahead of a planned expansion to 2 GW) is considerably smaller than leading tier-1 peers like Longi or JA Solar, which may mean longer lead times and less flexibility for large-volume contracts.

Notes from the database
  • Efficiency of 21.8% is 1.0pp below the TOPCon 600-650W median (22.8%)
  • Power density of 218.2 W/m² is 9.5 W/m² below TOPCon 600-650W median (227.7 W/m²) - needs more roof space
  • Temperature coefficient of -0.30%/°C matches the TOPCon 600-650W median
  • At 34.3 kg (1.6 kg above TOPCon 600-650W median of 32.7 kg), requires checking roof load capacity
  • Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof

Common questions

6 answered
What warranty does the Leapton LP182*182-M-78-NB series come with?
The LP182*182-M-78-NB series includes a 25-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. Leapton guarantees at least 87.4% of nominal power after 30 years of operation. This extended warranty schedule is made possible by the N-type TOPCon cell technology and dual glass encapsulation, both of which reduce long-term degradation.
Is the Leapton LP182*182-M-78-NB suitable for industrial rooftops and carports?
Yes, the LP182*182-M-78-NB series is specifically well-suited for these applications. The dual glass construction improves mechanical strength and moisture resistance, while bifacial design captures additional energy from light reflected off light-colored surfaces below. On carports and industrial rooftops with high albedo, real-world energy yield can be 5 to 15% higher than a comparable monofacial module.
How does the Leapton LP182*182-M-78-NB perform in hot weather?
N-type TOPCon technology offers a lower temperature coefficient of Pmax (approximately -0.30%/°C) compared to standard PERC modules (-0.35%/°C). When module temperature reaches 70°C during peak summer hours, the LP182*182-M-78-NB loses less power than a typical P-type panel. This advantage directly improves energy yield on hot, sunny days when solar irradiance is highest.
What is the peak power output and efficiency of the Leapton LP182*182-M-78-NB?
The top variant in this series delivers 625 Wp at a module efficiency of approximately 22.3%. The full series spans 610 to 625 Wp, built with 78 half-cut M10 cells (182×182 mm). For commercial and utility-scale PV projects, this translates into fewer modules needed to reach target system capacity and reduced balance-of-system costs.
How does the Leapton LP182*182-M-78-NB differ from standard monofacial PERC modules?
The key differences are threefold: N-type TOPCon cells instead of P-type PERC, bifacial energy harvest instead of single-sided, and dual glass encapsulation instead of a rear backsheet. Together these features deliver higher initial efficiency, slower long-term degradation (LID virtually eliminated), and better resistance to environmental stressors. The higher upfront cost is typically offset by greater cumulative energy yield over a 25-to-30-year project lifetime.
Is Leapton a reliable manufacturer and is the LP182*182-M-78-NB series available?
Leapton Solar is headquartered in Japan and is classified as a Bloomberg NEF Tier 1 manufacturer, confirming its financial stability and project bankability. The LP182*182-M-78-NB series is active and not discontinued. Availability in Poland depends on distributor stock levels for specific wattage variants, so it is worth confirming current inventory with your local supplier before placing an order.
