Middle of its segment, weak in heat
The Leapton LP182*182-M-72-MH series consists of modules based on monocrystalline cells cut in half and a 144-cell structure, designed for stable operation in real roof and industrial conditions. The use of MBB (multi-busbar) technology reduces resistive losses and improves energy harvesting, resulting in more reliable performance even when the installation is shaded or has less-than-ideal orientation.
A key feature of this series is high PID resistance, which helps to better control performance degradation over time, giving investors predictable production. The modules also undergo salt fog and ammonia corrosion tests, making them suitable for environments with high levels of environmental aggression. In addition, they have enhanced mechanical strength, which is important in windy areas and during winter loads.
This is a sensible choice for installers and investors looking for a series for residential, commercial, and PV farms, where energy yield, durability, and reduced risk of warranty claims are important.

Residential, commercial, utility-scale and shaded-installations.
Hot climates, owners who want a long output guarantee and roofs where every square metre has to count.
Bottom 1% of the TOPCon 500-550 W segment, against a median of -0.290. Ranked 12,345th in the whole database.
Bottom 3% of the TOPCon 500-550 W segment, against a median of 30 yrs. Ranked 9,798th in the whole database.
Bottom 3% of the TOPCon 500-550 W segment, against a median of 227.4. Ranked 10,202nd in the whole database.
TOPCon technology delivers lower LID/LeTID degradation and better high-temperature performance than older PERC cells, translating into higher real-world annual yield in rooftop and industrial installations.
Peak efficiency of 21.67% at up to 560 Wp places the series at the top tier of the segment, on par with comparable models from Exiom (21.7%), Fellow Energy (21.7%), and Premier Energies (21.67%).
Modules passed salt spray and ammonia corrosion testing (TUV Nord) and feature high PID resistance, making them well suited for coastal, agricultural, and industrial sites with elevated environmental aggressiveness.
The panel withstands wind loads up to 2400 Pa and snow loads up to 5400 Pa, providing a real safety margin for installations in windy regions or areas with heavy snow cover.
The multi-busbar design lowers internal resistance and losses under lower irradiance, improving energy harvest during cloud cover or non-optimal panel orientation.
Production of the LP182*182-M-72-MH ended in 2023 (launched 2021), meaning limited availability of units for expanding existing arrays and potentially harder warranty servicing going forward.
A 15-year product warranty is a legacy standard - newer Tier-1 TOPCon series entering the market since 2024 already offer 20-25 years of product warranty, making this parameter comparatively modest against current market offerings.
The MH series is monofacial, while some direct competitors with similar power and efficiency (e.g., Premier Energies 144 Half Cut Bifacial Dual Glass) offer bifacial modules, adding extra yield from albedo in ground-mount or high-reflectivity installations.
- Efficiency of 20.9% is 1.8pp below the TOPCon 500-550W median (22.7%)
- Power density of 208.9 W/m² is 18.5 W/m² below TOPCon 500-550W median (227.4 W/m²) - needs more roof space
- Temperature coefficient of -0.36%/°C is 0.07pp worse than TOPCon 500-550W median (-0.29%/°C) - higher losses in summer heat
- In the top 72% for efficiency among all TOPCon panels
