Light for its output, modest efficiency
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.

Signals from the data
Utility-scale, commercial and hot-climate.
Tight roof space, roofs where every square metre has to count and hot climates.
Top 9% of the TOPCon 600-650 W segment, against a median of 53.1. Ranked 1,141st in the whole database.
Bottom 18% of the TOPCon 600-650 W segment, against a median of 22.80%.
Bottom 18% of the TOPCon 600-650 W segment, against a median of 227.7.
Bottom 19% of the TOPCon 600-650 W segment, against a median of -0.290.
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.
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.
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.
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.
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.
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.
- Efficiency of 22.4% matches the TOPCon 600-650W median
- Power density of 223.6 W/m² is 4.1 W/m² below TOPCon 600-650W median (227.7 W/m²) - needs more roof space
- At -0.30%/°C, hot weather performance is typical for TOPCon 600-650W panels
- Weight of 29.0 kg (3.7 kg below TOPCon 600-650W median of 32.7 kg) allows easier transport and roof mounting
- In the top 36% for efficiency among all TOPCon panels
