This translates into higher cumulative energy yield over the full 30-year service life. - **High module efficiency up to 23.18%** - 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%). - **Tier-1 bankability per BloombergNEF** - 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. - **Extended product and power warranty** - 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. - **Large 210mm cell format and high unit power** - 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. ## Cons - **No bifacial variant available** - 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. - **Efficiency marginally trails segment leaders** - 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. ## About this series 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. ## Notable figures - At 23.2% efficiency, this panel is on par with typical \*\*TOPCon 700-750W\*\* modules - At 231.8 W/m² power density, roof space requirements are typical for \*\*TOPCon 700-750W\*\* panels - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 700-750W\*\* median - 34.0 kg weight - 4.0 kg lighter than \*\*TOPCon 700-750W\*\* median (38.0 kg), reducing installation effort - In the top 10% for efficiency among all TOPCon panels ## Questions ### What warranty does the Leapton LP210\*210-M-66-NH series come with? Leapton backs the LP210\*210-M-66-NH series with a 25-year product warranty and a 30-year linear power output warranty. Annual degradation is capped at 0.4%, meaning the module retains significantly more of its rated output after three decades than older PERC-based panels. This places it among the most competitive warranty packages available in the commercial large-format segment. ### What is the difference between the LP210\*210-M-66-NH and the LP210\*210-M-66-NB variant? The key distinction is module construction: the NH variant is monofacial, while the NB is bifacial and harvests reflected light from the rear surface as well. LP210\*210-M-66-NH is the right choice when the back of the panel has no useful albedo contribution — for instance, on rooftops with dark membranes or ground mounts over dark soil. The decision between the two variants depends on the albedo of the mounting surface. ### Are LP210\*210-M-66-NH panels compatible with 1500V DC inverters? Yes, the LP210\*210-M-66-NH series supports a maximum system voltage of 1500V DC. This enables longer strings with fewer inverters or combiner boxes, reducing overall BoS costs and simplifying system design. It is a meaningful advantage when engineering utility-scale PV farms or large commercial installations where infrastructure cost optimization is a priority. ### How large and heavy are LP210\*210-M-66-NH modules — can they be installed on a standard warehouse roof? Each LP210\*210-M-66-NH module measures 2384×1303×35 mm and weighs approximately 34 kg. This large format requires a structurally sound roof and at least a two-person installation crew. Warehouses and industrial facilities with flat or low-slope roofs are a typical application for this series, though a structural load assessment should always be completed prior to installation. ### Does the TOPCon technology in the LP210\*210-M-66-NH improve energy yield on cloudy days? Yes. N-type TOPCon cells deliver higher output under low-irradiance conditions compared to PERC technology, and they also carry a lower temperature coefficient, which reduces power loss during hot summer days. In climates with frequent overcast conditions — typical of Central Europe — these characteristics translate into measurably higher annual energy yield per installed kilowatt-peak. ### How many cells does the LP210\*210-M-66-NH have, and how does this affect shading tolerance? The LP210\*210-M-66-NH uses 132 half-cut cells measuring 210×210 mm in a 66×2 layout. Splitting cells in half reduces resistive losses and improves partial-shading behavior — a shadow covering one section of the panel limits output only on that half-string, not the entire module. This is particularly relevant in commercial and industrial installations where chimneys, HVAC units, or adjacent structures may cast intermittent shadows. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/2024-08-02-140700-5d84b22d01b8.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | -40 W, lighter, +2.0 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | -45 W, lighter, +1.8 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | -20 W, cooler, +1.8 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | -25 W, cooler, +1.7 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -50 W, lighter, +1.6 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | -50 W, lighter, +1.6 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | -50 W, cooler, +1.6 pp | | [Leapton LP210\*210-M-66-NB-690W](https://comparepv.com/panel/leapton-lp210-210-m-66-nb-690w) | 690 W | -30 W, heavier, -1.0 pp | | [Leapton LP210\*210-M-66-NH-695W](https://comparepv.com/panel/leapton-lp210-210-m-66-nh-695w) | 695 W | -25 W, -0.8 pp | | [Leapton LP210\*210-M-66-NH-700W](https://comparepv.com/panel/leapton-lp210-210-m-66-nh-700w) | 700 W | -20 W, -0.6 pp | | [Leapton LP210\*210-M-66-NH-705W](https://comparepv.com/panel/leapton-lp210-210-m-66-nh-705w) | 705 W | -15 W, -0.5 pp | | [Leapton LP210\*210-M-66-NH-710W](https://comparepv.com/panel/leapton-lp210-210-m-66-nh-710w) | 710 W | -10 W, -0.3 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +85 W, heavier, +1.9 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +80 W, heavier, +1.7 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +75 W, heavier, +1.6 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +70 W, heavier, +1.4 pp | --- Source: https://comparepv.com/panel/leapton-lp210-210-m-66-nh-720w Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
