The Leapton LP182*199-M-66-NH series is an advanced solution based on N-type TOPCon cells, which are a response to growing demands for efficiency in challenging lighting conditions. Thanks to the use of this technology, the modules offer a significantly lower annual degradation rate compared to traditional P-type panels, guaranteeing stable energy yields for decades. The design utilizing half-cut technology effectively minimizes power losses caused by partial shading and reduces internal resistance, which directly translates into higher efficiency for the entire photovoltaic system. These models stand out with exceptional performance in low-light conditions, which in the Polish climate allows for effective power generation even under heavy cloud cover. This series solves key investor problems by offering a better temperature coefficient, thanks to which the modules lose less power during hot days. It is a product dedicated to both large-scale farms and modern commercial installations, where maximizing power density per square meter is essential. Leapton focuses on durability and innovation, delivering modules with high mechanical resistance, which sets them apart from standard solutions and ensures a faster return on investment for the most demanding users.

What owners get
N-type TOPCon cell technology

N-type TOPCon cells deliver lower LID/LeTID degradation and a better power temperature coefficient (-0.3%/°C) than legacy P-type PERC modules, translating into higher and more stable energy yield, especially on hot days.

High efficiency up to 22.83%

Module efficiency reaching 22.83% places the series among the segment's top performers, on par with Talesun TM7G72M (22.8%) and Horay Solar HS 182-144 TC-D (22.8%), maximizing power output from limited roof or land area.

30-year linear power warranty

The manufacturer guarantees a minimum of 87.4% of rated power after 30 years, backed by a 25-year product warranty — a premium-tier standard for TOPCon modules that ensures predictable, long-term investment returns.

Half-cut design, 132 cells

Half-cut cell technology (132 cells) reduces power loss from partial shading and lowers the module's internal resistance, boosting overall system performance, particularly under variable irradiance conditions.

Tier-1 status and wide 570-590 Wp power range

Leapton holds BNEF Tier-1 status (bankability confirmed via non-recourse project finance), and the series' 5 power variants spanning 570-590 Wp allow flexible fitting for utility-scale and commercial installations.

Trade-offs
Monofacial-only variant

Unlike comparable peer series (Talesun TM7G72M BIPRO and Horay Solar HS 182-144 TC-D Ocean), which offer bifacial modules, the NH variant of this Leapton series is monofacial, forfeiting the additional rear-side energy gain available in ground-mount or high-albedo tracker installations.

Common questions

6 answered
What is the maximum power output and efficiency of the Leapton LP182*199-M-66-NH?
The top model in the LP182*199-M-66-NH series reaches a maximum power output of 590 Wp with module efficiency up to 22.83%. This is well above the market average for premium-class panels, made possible by N-type TOPCon half-cut cell technology. The high power density means you need less roof area to achieve the same energy production compared to older PERC-based technology.
Does the Leapton LP182*199-M-66-NH perform well under overcast or low-light conditions?
Yes, N-type TOPCon cells are known for their excellent low-irradiance performance, which is critical in climates with frequent cloud cover. Compared to standard PERC panels, TOPCon technology generates proportionally more energy in diffuse light conditions, resulting in higher annual energy yields without increasing the number of modules installed.
How does the LP182*199-M-66-NH handle high temperatures – does it lose much power on hot days?
The LP182*199-M-66-NH series has a temperature coefficient of just -0.30%/°C, which is among the lowest values available in mass-market modules. A typical PERC panel loses -0.35%/°C. In practice, at a module temperature of 65°C, the Leapton panel produces measurably more power than average competitors. This advantage compounds across summer months and positively impacts annual LCOE.
What warranty does the Leapton LP182*199-M-66-NH series come with?
The manufacturer provides a 25-year product warranty covering material and workmanship defects, plus a 30-year linear power warranty guaranteeing at least 87.4% of nominal output after three decades of operation. This is one of the longer power warranties available in the mainstream panel segment. As a Tier 1 manufacturer headquartered in Japan, Leapton Solar offers reliable warranty backing.
What are the dimensions and weight of the LP182*199-M-66-NH – is it practical for residential roof installation?
The module measures approximately 2279 × 1134 × 30 mm and weighs around 27 kg. This is a large and relatively heavy 66-cell format panel, so it is worth verifying the roof's load-bearing capacity before purchase and ensuring the installation crew has proper equipment for safe transport on the roof. The module withstands wind loads of 2400 Pa and snow loads of 5400 Pa, making it suitable for Central European climate conditions.
Is the LP182*199-M-66-NH a bifacial or monofacial panel?
The LP182*199-M-66-NH series is a monofacial module, meaning it collects solar energy from the front side only. This makes it the optimal choice for rooftop installations where no reflected light reaches the back of the panel. The absence of a dual-glass or transparent backsheet simplifies installation and reduces the module cost compared to bifacial variants. For ground-mounted systems with a light-colored surface, consider the bifacial NB variants instead.
