Light for its output, weak in heat
The Leapton LP210*210-M-66-NH series is designed for maximum power generation from large mounting areas, where high power density and predictable performance over many years are crucial. The use of N-type cells helps to minimize typical performance losses seen in older technologies, resulting in more stable energy production throughout the lifespan of the installation. The modules in this series also feature large 210mm cell format, making it easier to complete the project to the desired power output without adding additional rows of panels.
In practice, LP210*210-M-66-NH solves a common problem for investors - how to increase power generation from a limited roof or ground-mounted area, without complicating the project. It is a good choice for PV farms, warehouses, and manufacturing plants, where lower degradation and consistent parameters in large deliveries are important. The series also supports operation in higher voltage systems, which simplifies the optimization of strings and BOS balance, distinguishing it from many standard modules in the commercial segment.
Ranking
Signals from the data
Commercial and utility-scale.
Hot climates.
Top 13% of the TOPCon 700-750 W segment, against a median of 52.9.
Bottom 22% of the TOPCon 700-750 W segment, against a median of -0.290.
N-type TOPCon technology delivers an annual degradation rate of 0.4%, clearly lower than older P-type PERC modules (typically 0.55-0.7%/year). This translates into higher cumulative energy yield over the full 30-year service life.
Module efficiency reaching 23.18% places the series among the leaders of the commercial segment, on par with competing TOPCon series such as DMEGC DMxxxG12T-B66HSW and GCL-NH12/66GDF (both up to 23.2%).
Leapton is listed on the BloombergNEF Tier-1 list, confirming manufacturer financial stability and easing project financing through banking institutions - important for large PV farm and commercial installations.
A 25-year product warranty and 30-year linear power warranty exceed the market standard (typically 12-15 years product and 25 years power for many competitors), reducing long-term risk for investors.
Modules reaching up to 720Wp with 132 cells in the 210mm format allow fewer panels and shorter strings per required system power, easing BoS optimization and enabling higher system voltage operation.
The series is offered only in a monofacial version, while the 700+Wp TOPCon segment increasingly offers bifacial variants delivering an additional 5-10% yield in ground-mount installations and on bright roofing surfaces.
Maximum efficiency of 23.18% is slightly below comparable competitor series (DMEGC, GCL, Hanersun - up to 23.2%), meaning at identical 720Wp max power there is no real technological edge over rivals.
- At 23.1% efficiency, this panel is on par with typical TOPCon 700-750W modules
- At 230.2 W/m² power density, roof space requirements are typical for TOPCon 700-750W panels
- At -0.30%/°C, hot weather performance is typical for TOPCon 700-750W panels
- 34.0 kg weight - 4.0 kg lighter than TOPCon 700-750W median (38.0 kg), reducing installation effort
- #1567 for efficiency, #6093 for temperature performance out of 14005 panels
