The use of **N-type monocrystalline** cells and **MBB technology** results in improved power generation from the entire cell surface and reduced losses in practical installations, particularly where high repeatability of yields is important. A key advantage of this series is **dual-sided energy generation** - the panel can recover additional power from the rear side as well, when the installation has a suitable substrate or is mounted on structures that promote light reflection. In real conditions in Poland, this also leads to **better performance under less sunlight**, which is particularly important in winter and on cloudy days. This is a good choice for PV farms, large commercial rooftops, and industrial installations where durability, environmental resistance, and predictable energy production over the years are important. ## Notable figures - Efficiency of 22.1% matches the \*\*TOPCon 550-600W\*\* median - Power density of 220.6 W/m² is 3.8 W/m² below \*\*TOPCon 550-600W\*\* median (224.4 W/m²) - needs more roof space - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - Ranked #6205 out of 14005 panels for efficiency in the database ## Questions ### How does the TOPCon technology in the Leapton LP182\*182-M-72-NB differ from standard PERC modules? The N-type TOPCon cells in the LP182\*182-M-72-NB series feature a tunnel oxide passivation layer that reduces carrier recombination losses. As a result, module efficiency reaches up to 22.64% and the temperature coefficient of Pmax is only -0.30%/°C. By comparison, typical PERC (P-type) modules deliver approximately -0.35%/°C and lower efficiency, meaning higher power losses on hot days and weaker performance under diffuse irradiance. ### What warranty does the Leapton LP182\*182-M-72-NB series come with? Leapton provides a 25-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. After 30 years of operation, the module is guaranteed to retain at least 87.4% of its nominal rated power. This is one of the longest power warranties available on the market and a key factor when calculating ROI for commercial PV installations. ### How much more energy will the bifacial Leapton LP182\*182-M-72-NB produce compared to a standard monofacial panel? The bifacial LP182\*182-M-72-NB can generate 5 to 25% more energy than a comparable monofacial panel, depending on ground surface reflectivity (albedo). Best results are achieved in ground-mounted installations with light-colored gravel, white membranes, or snow coverage. On dark rooftops, a realistic bifacial gain is typically 5-10%, which is why bifacial modules pay off most in utility-scale farm projects. ### Do the Leapton LP182\*182-M-72-NB panels perform well in Central European climates with frequent cloud cover? Yes, the LP182\*182-M-72-NB series is well suited to Central European conditions. N-type TOPCon cells demonstrate better low-light performance compared to standard PERC modules. The low temperature coefficient of -0.30%/°C minimizes power losses during summer heat, while the MBB (multi-busbar) cell architecture reduces the impact of partial shading on overall panel output — an important factor during overcast winter days. ### How large and heavy are the Leapton LP182\*182-M-72-NB modules, and what installation types do they suit best? The LP182\*182-M-72-NB modules measure 2279×1134×30 mm and weigh 32 kg. These are typical dimensions for 72-cell 585W panels designed primarily for ground-mounted farms, large commercial rooftops, and industrial facilities. The dual glass construction provides wind load resistance up to 2400 Pa and snow load up to 5400 Pa (TÜV Nord certified). Residential rooftop installation is technically feasible but requires an adequately rated mounting structure. ### Is Leapton a bankable manufacturer and is the LP182\*182-M-72-NB series a safe choice for project financing? Leapton Solar is a Japanese Tier 1 manufacturer, recognized by independent industry agencies as financially stable and technically reliable. TÜV Nord certification, PID protection, and compliance with environmental stress tests (salt mist, ammonia, sand, hail) make the LP182\*182-M-72-NB series meet the bankability requirements of financial institutions funding utility-scale PV projects. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/948516d1f2dc0ca2a40a05f778e402d6-4714113d151b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.7 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.5 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, 16 kg lighter, +2.3 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, lighter, +2.3 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Cooler, lighter, +2.3 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | Cooler, lighter, +2.2 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Cooler, lighter, +2.1 pp | | [Leapton LP182\*182-M-72-MH-540W](https://comparepv.com/panel/leapton-lp182-182-m-72-mh-540w) | 540 W | Hotter, lighter, -1.2 pp | | [Leapton LP182\*182-M-72-MH-545W](https://comparepv.com/panel/leapton-lp182-182-m-72-mh-545w) | 545 W | Hotter, lighter, -5 yr warranty | | [Leapton LP182\*182-M-72-MH-550W](https://comparepv.com/panel/leapton-lp182-182-m-72-mh-550w) | 550 W | Hotter, lighter, -5 yr warranty | | [Leapton LP182\*182-M-72-MH-555W](https://comparepv.com/panel/leapton-lp182-182-m-72-mh-555w) | 555 W | Hotter, lighter, -5 yr warranty | | [Leapton LP182\*182-M-72-MH-560W](https://comparepv.com/panel/leapton-lp182-182-m-72-mh-560w) | 560 W | Hotter, lighter, -5 yr warranty | | [Leapton LP182\*182-M-72-NB-565W](https://comparepv.com/panel/leapton-lp182-182-m-72-nb-565w) | 565 W | Very close match | | [Leapton LP182\*199-M-66-NH 575W](https://comparepv.com/panel/leapton-lp182-199-m-66-nh-575w) | 575 W | Lighter | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +80 W, lighter, +3.1 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +75 W, lighter, +2.9 pp | --- Source: https://comparepv.com/panel/leapton-lp182-182-m-72-nb-570w Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
