In practice, this translates to more energy from the same roof area or from a limited ground-mounted structure, without the need to add additional panels. The use of a half-cut configuration helps to stabilize performance under partial shading and thermal loads, while the monofacial design facilitates compatibility with traditional pitched roofs, flat roofs, and commercial installations, where predictability is key. Compared to many competing series, it stands out due to its **210R format** and **low degradation over time**, ensuring long-term high energy production. An additional advantage is the **positive power tolerance**, which reduces the risk of parameter drift in larger strings, as well as **high environmental resistance** with a sealed junction box, which is crucial in Polish weather conditions. ## Notable figures - Efficiency of 22.9% matches the \*\*TOPCon 500-550W\*\* median - At 229.3 W/m² power density, roof space requirements are typical for \*\*TOPCon 500-550W\*\* panels - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 500-550W\*\* panels - Weight of 23.7 kg (3.3 kg below \*\*TOPCon 500-550W\*\* median of 27.0 kg) allows easier transport and roof mounting - Ranked #2342 out of 14005 panels for efficiency in the database ## Questions ### What warranty does the Leapton LP182\*210-M-54-NH come with and what does it cover? The LP182\*210-M-54-NH series comes with a 25-year product warranty covering manufacturing defects and materials, plus a 30-year linear power warranty guaranteeing at least 87.4% of rated output after the full term. For a 10 kWp system, this translates to three decades of predictable energy production without needing panel replacements — one of the longer coverage periods available on the market. ### How does the N-type TOPCon technology in the LP182\*210-M-54-NH compare to older PERC cells? N-type TOPCon cells use a tunnel oxide passivated contact structure that delivers higher module efficiency — up to approximately 22.9% — and a lower temperature coefficient of -0.30%/°C. Compared to standard PERC, this means smaller output losses on hot summer days and slower long-term degradation, which is particularly relevant given the 30-year power warranty period. ### Are the Leapton LP182\*210-M-54-NH panels suitable for a typical pitched roof installation? Yes, the monofacial design of the LP182\*210-M-54-NH series is built for exactly these applications. Module dimensions are approximately 1961×1134×30 mm with a weight of 27.7 kg, fitting standard pitched-roof mounting systems. The sealed junction box handles rain and snow exposure, and the module is rated for snow loads up to 5400 Pa and wind loads up to 2400 Pa. ### What advantage does the 210R cell format in the LP182\*210-M-54-NH offer compared to standard square cells? The 210R format uses rectangular 182×210 mm cells that pack more tightly within the module frame than traditional square cells, maximizing active area per module. This means higher energy output from the same roof or ground area without adding more panels. For space-constrained installations, it shortens payback time by squeezing more watts per square meter. ### Does the half-cut cell layout in the LP182\*210-M-54-NH help when part of the panel is shaded by a chimney? Yes. The half-cut design splits each cell, allowing the top and bottom halves of the module to operate independently. When a chimney or dormer shades the lower portion of a panel, the upper half continues generating at full capacity without causing a proportional drop across the entire string. This is especially useful in residential installations where partial shading from roof elements is common throughout the year. ### Is Leapton a reliable manufacturer and are the LP182\*210-M-54-NH panels available in Europe? Leapton Energy, headquartered in Japan, holds Tier 1 status as independently verified by financial and technical rating agencies, confirming manufacturing quality and company stability. The LP182\*210-M-54-NH series is an active product line and is available through European distributors. It is worth checking current stock levels with your local supplier, as availability of specific wattage variants may vary. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/cd3a160be22874fa17d24cb573dadbce-25581b436828.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +2.1 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +1.9 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +50 W, cooler, +1.9 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, +1.8 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +45 W, cooler, +1.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +1.6 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | -10 W, cooler, +1.6 pp | | [Leapton LP182\*182-M-60-NH-480W](https://comparepv.com/panel/leapton-lp182-182-m-60-nh-480w) | 480 W | -30 W, -1.3 pp | | [Leapton LP182\*182-M-60-NH-485W](https://comparepv.com/panel/leapton-lp182-182-m-60-nh-485w) | 485 W | -25 W, -1.1 pp | | [Leapton LP182\*210-M-54-NH-490W](https://comparepv.com/panel/leapton-lp182-210-m-54-nh-490w) | 490 W | -20 W, -0.9 pp | | [Leapton LP182\*182-M-60-NH-490W](https://comparepv.com/panel/leapton-lp182-182-m-60-nh-490w) | 490 W | -20 W, -0.8 pp | | [Leapton LP182\*182-M-60-NB-495W](https://comparepv.com/panel/leapton-lp182-182-m-60-nb-495w) | 495 W | -15 W, heavier, -0.6 pp | | [Leapton LP182\*210-M-54-NH-495W](https://comparepv.com/panel/leapton-lp182-210-m-54-nh-495w) | 495 W | -15 W, -0.7 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +40 W, lighter, +1.5 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +30 W, cooler, +1.5 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +30 W, cooler, +1.5 pp | --- Source: https://comparepv.com/panel/leapton-lp182-210-m-54-nh-510w 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.
