Middle of its segment, weak in heat
The Leapton LP182*210-M-66-NB series is designed for installations where high energy production from a given area and stable operation in more challenging conditions are crucial. These are dual-sided (bifacial) modules with a dual-glass construction, allowing them to also utilize reflected light from the ground - a significant advantage, especially on bright roofs, membranes, and ground-mounted installations. The use of N-type TOPCon cells results in improved resistance to typical performance losses over time and more predictable performance at high temperatures. Another key feature of this series is high mechanical durability, which is important for snow and wind loads, a significant factor in the Polish climate. The series is also complemented by a longer warranty package, which supports investors seeking a safe return on their investment. The LP182*210-M-66-NB is well-suited for PV farms, large commercial roofs, and projects where maximizing yield is important without increasing the number of modules.
Ranking
Signals from the data
Commercial, utility-scale and cold-climate.
Hot climates.
Bottom 19% of the TOPCon 600-650 W segment, against a median of -0.290.
Bifacial design captures reflected light from the ground surface, yielding an estimated additional 5-25% energy gain depending on albedo, per manufacturer data. A real advantage on light-colored roofs, PVC membranes, and ground-mount installations.
Annual power degradation of around 0.4% combined with a Pmax temperature coefficient of -0.3%/°C mean more stable performance on hot days and higher energy yield over 20-30 years compared to older PERC technology.
Peak efficiency of 23.32% matches top-tier peers such as Resun RS8H-M-BD (23.32%) and Jinko Tiger Neo 66HL4M-BDV (23.32%), and edges out Canadian Solar TOPBiHiKu6 Anti-Dust (23.3%) at the same 630 Wp max power.
The manufacturer guarantees a minimum of 87.4% of rated power after 30 years, and Leapton holds BNEF Tier-1 status, confirming module deployment across at least six projects backed by different non-recourse project finance banks — key for bank-financed commercial and utility-scale PV projects.
High mechanical load rating is relevant for snow and wind loads typical in Poland, reducing microcrack and failure risk during winter on large rooftop arrays.
The 23.32% max efficiency is identical to Resun RS8H-M-BD and Jinko Tiger Neo 66HL4M-BDV, so this metric isn't a real technical differentiator — it merely matches the current standard for premium TOPCon modules.
Leapton has been operating since 2012, considerably less than players like Canadian Solar (since 2001) or Jinko Solar (since 2006), which — despite the same BNEF Tier-1 classification — may raise questions about manufacturing scale and long-term warranty servicing stability.
- At 23.1% efficiency, this panel is on par with typical TOPCon 600-650W modules
- At 231.4 W/m² power density, this panel generates 3.7 W/m² more per unit area than TOPCon 600-650W median (227.7 W/m²)
- At -0.30%/°C, hot weather performance is typical for TOPCon 600-650W panels
- Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof
- #1509 for efficiency, #6093 for temperature performance out of 14005 panels
