The Leapton LP182*199-M-72-NH panel series is an advanced solution based on innovative N-type TOPCon cell technology, which redefines efficiency standards in variable lighting conditions. Thanks to the use of larger silicon wafers and a bifacial design, these modules maximize energy yield not only from direct solar radiation, but also from light reflected from the ground. This is a key advantage for investors building ground-mounted farms or large commercial installations, where every watt obtained from the available surface counts. The use of the SMBB (Super Multi Busbar) structure allows for a significant reduction in resistive losses and better current flow, which directly translates into stable system operation for decades. This series effectively solves the problem of light-induced degradation, offering exceptional resistance to LID and LeTID phenomena, which significantly distinguishes it from older P-type solutions available on the market. By choosing these modules, the investor gains a product with an exceptionally low temperature coefficient, which guarantees high production even on hot days. It is an optimal choice for large-scale projects that require the highest reliability and maximization of profits through increased power density while maintaining high mechanical resistance of the entire structure.

What owners get
Low -0.3%/°C temperature coefficient

N-type TOPCon cells lose power more slowly as temperature rises compared to conventional PERC cells (typically -0.35 to -0.40%/°C), resulting in higher real-world energy yield on hot days and in high-irradiance climates.

Tier-1, bankable manufacturer

Leapton is classified as a Tier-1 manufacturer, headquartered in Japan and operating since 2012. Bankable status simplifies project financing through banks and investment funds, reducing risk for large-scale investors.

30-year linear power warranty

A 30-year power warranty (minimum 87.4% of nominal power retained) alongside a 25-year product warranty places the series on par with peer comparables (Canadian Solar, Resun Solar, Jinko Solar), strengthening long-term investment security.

SMBB structure reduces resistive losses

Super Multi Busbar technology lowers resistive losses and micro-crack risk on cells, translating into more stable module performance over the panel's lifetime, especially in high power-density installations.

Resistant to LID/LeTID degradation

N-type TOPCon technology eliminates the light-induced degradation (LID) and LeTID issues typical of P-type cells, limiting power loss in the early years of operation compared to older PERC solutions.

Trade-offs
Lower efficiency than competitors

Efficiency of 22.18-22.54% is noticeably lower than comparable 630 Wp competitor models: Canadian Solar TOPBiHiKu6 (23.3%), Resun RS8H-M-BD TOPCon (23.32%), and Jinko Tiger Neo 66HL4M-BDV (23.32%). At the same peak power, this means a larger module footprint, which can matter on roof- or land-constrained sites.

Common questions

6 answered
What warranty does the Leapton LP182*199-M-72-NH series come with?
The LP182*199-M-72-NH series carries a 25-year product warranty covering material and workmanship defects. In addition, Leapton provides a 30-year linear power output warranty guaranteeing at least 87.4% of nominal power after three decades of operation. This is one of the longest warranty packages available in the PV module market, reflecting the manufacturer's confidence in the long-term reliability of its N-type TOPCon technology.
How do Leapton LP182*199-M-72-NH panels compare to standard PERC modules?
The primary difference is cell technology: LP182*199-M-72-NH uses N-type TOPCon instead of the older P-type PERC. N-type cells are virtually immune to light-induced degradation (LID and LeTID), which progressively reduces PERC module output in the first years of operation. Leapton's module efficiency reaches 22.54%, compared to a typical PERC at 20–21%, delivering more energy from the same roof or ground area.
Do Leapton LP182*199-M-72-NH panels perform well during hot summer days?
Yes. The power temperature coefficient for this series is -0.30%/°C, meaning lower thermal losses than typical PERC modules (-0.35%/°C). For example, at a module temperature of 65°C — common in summer — the panel loses approximately 13.5% of its rated power rather than ~16%. In practice this translates to noticeably higher real-world energy yield during peak summer months.
What are the dimensions and weight of the Leapton LP182*199-M-72-NH module, and does it affect installation?
Each module measures 2465 × 1134 × 30 mm and weighs 29 kg. This is a large-format module intended primarily for ground-mount utility-scale projects and large commercial rooftops, where mechanical handling equipment is used. For residential rooftop installations, the size and weight require careful logistics planning and a larger installation crew compared to standard residential-size panels.
Is the LP182*199-M-72-NH series a good choice for a solar farm over 1 MW?
Yes, this series is purpose-built for utility-scale projects. The 630 Wp peak power and up to 22.54% module efficiency allow reaching target capacity with fewer modules and shorter wiring runs. Leapton holds Bloomberg NEF Tier-1 status, which simplifies project bankability. The SMBB structure minimizes resistive losses, ensuring stable output throughout the full 30-year power warranty period.
Are Leapton LP182*199-M-72-NH modules monofacial or bifacial?
The LP182*199-M-72-NH series is monofacial — the NH suffix in the model name denotes a standard opaque backsheet. Leapton offers a separate bifacial variant under the designation LP182*199-M-72-NB, which harvests reflected albedo light from the ground surface. For typical rooftop installations the monofacial NH version is fully sufficient and is generally available at a lower price point.
