Middle of its segment, weak in heat
The Leapton LP210*210-M-66-NB series is designed to maximize energy production from every square meter, even under less-than-ideal conditions. The use of N-type cells in combination with MBB technology helps to minimize losses and stabilize module performance, resulting in more predictable annual energy production. A key advantage of this series is the glass-to-glass bifacial design, which allows for the utilization of reflected light from the ground - particularly beneficial on bright roofs, membranes, gravel, or in ground-mounted installations.
In practice, this solves a common problem for investors: how to increase energy production without expanding the mounting area. These modules are also designed for high mechanical durability and PID protection, which is important in PV farms, carports, and large industrial rooftops, where durability and lower risk of performance degradation are crucial. Compared to many competing single-sided panels, the LP210*210-M-66-NB offers a real advantage where light can be utilized from "both sides".

Bottom 22% of the TOPCon 700-750 W segment, against a median of -0.290.
N-type TOPCon cells combined with multi-busbar (MBB) technology reduce resistive losses and improve low-light performance, resulting in more stable annual energy yield compared to older PERC modules.
Bifacial glass-glass modules with 210x210 mm cells deliver an additional 5-25% energy output from rear-side irradiance capture, which is particularly cost-effective on light-colored roofs, membranes, gravel surfaces, or ground-mount installations - without expanding the mounting footprint.
The manufacturer guarantees 87.4% of rated power retention after 30 years, backed by a 25-year product warranty - a premium standard among leading tier-1 manufacturers that surpasses the typical 25-year power warranties offered by many competitors.
Modules passed TUV Nord testing for wind loads up to 2400 Pa and snow loads up to 5400 Pa, with built-in PID protection minimizing performance degradation risk - important for utility-scale farms, carports, and large industrial rooftops.
Leapton Energy maintains Tier-1 status per BloombergNEF (confirmed as recently as Q3 2024) and was recognized as a Top Performer in the Kiwa PVEL PV Module Reliability Scorecard 2025, confirming the series' bankability and credibility with project financiers.
Maximum power of 720 Wp and 23.18% efficiency are effectively identical to comparable peer series - DMEGC DMxxxG12T-B66HSW, GCL-NH12/66GDF, and Hanersun Hitouch 6N (all 720 Wp, 23.2%). The series does not stand out on power specs and merely matches the segment's N-type TOPCon standard.
The dual-glass construction, measuring 2384x1303x33 mm, weighs approximately 37.5 kg - typical for bifacial glass-glass modules, but resulting in higher structural mounting requirements and transport/installation costs compared to lighter monofacial backsheet modules.
- Efficiency of 23.2% matches the TOPCon 700-750W median
- Power density of 231.8 W/m² matches the TOPCon 700-750W median
- Temperature coefficient of -0.30%/°C matches the TOPCon 700-750W median
- Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof
- #1424 for efficiency, #6093 for temperature performance out of 14005 panels
