The use of **N-type cells in MBB technology** minimizes internal losses and improves performance under partial shading, which effectively helps maintain production in typical Polish roof and ground-mounted conditions. A key advantage is the **double-sided (bifacial) glass-to-glass construction** - the panel can also utilize reflected light from the ground, which increases profitability, for example, on bright roofs, on the ground, on elevated structures, and in carports. The glass on both sides also provides **higher resistance to moisture and environmental factors**, and additional **PID-resistant** features support long-term power stability. This is a good choice for installers and investors who are looking for modules that stand out for their durability, better performance in low light conditions, and greater tolerance to harsh working conditions. ## Notable figures - Efficiency of 22.6% matches the \*\*N-type 500-550W\*\* median - At 225.5 W/m² power density, roof space requirements are typical for \*\*N-type 500-550W\*\* panels - Temperature coefficient of -0.30%/°C matches the \*\*N-type 500-550W\*\* median - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - #3905 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### What warranty does the Leapton LP182\*182-M-60-NB series come with and what does it cover? The LP182\*182-M-60-NB series includes a 25-year product warranty and a 30-year linear power warranty. In year one, at least 99% of rated output is guaranteed, and after 30 years the module retains a minimum of 87.4% of its nominal power. Leapton is a Tier 1 manufacturer headquartered in Japan, which adds confidence that warranty claims will be honored throughout the panel's service life. ### Do the Leapton LP182\*182-M-60-NB panels perform well in winter and on overcast days typical of Central European climates? Yes. The temperature coefficient of Pmax is -0.3%/°C, one of the best figures in this module class. N-type TOPCon cells exhibit low LID and superior low-irradiance efficiency compared to P-type PERC. In Poland, where a significant share of annual yield comes from diffuse-light days, this advantage results in a measurable increase in total annual energy production. ### When does the bifacial design of the LP182\*182-M-60-NB actually deliver a meaningful yield gain? The bifacial design captures reflected irradiance from the rear side, adding 5–25% in additional yield depending on ground albedo. Gains are highest on ground-mount systems, carports, elevated racking structures, and roofs with bright gravel or white membranes beneath the array. On a conventional pitched roof with dark tiles, rear-side contribution is minimal, so the bifacial advantage is best exploited in open-field installations. ### Can the LP182\*182-M-60-NB modules handle heavy snow and strong wind loads on Central European rooftops? Yes. The double-glass construction has been TÜV Nord certified for a snow load of 5400 Pa (approximately 550 kg/m²) and a wind load of 2400 Pa, both exceeding standard requirements for most locations in Poland. The glass-glass encapsulation also provides significantly better moisture resistance and mechanical integrity compared to glass-backsheet modules. ### What is the practical difference between N-type TOPCon and standard P-type PERC cells, and why does it matter for the system owner? N-type TOPCon cells in the LP182\*182-M-60-NB series reach efficiency up to 22.55% and exhibit substantially lower LID than P-type PERC. This means more kilowatt-hours per square meter of roof space over the full system lifetime. Combined with the 30-year power warranty, the resulting LCOE of an installation built on this series is typically lower than equivalent capacity using conventional P-type modules. ### What are the dimensions and weight of the Leapton LP182\*182-M-60-NB panel, and will it fit on a standard pitched roof? The module measures 1955 × 1134 × 30 mm and weighs 27 kg. This is a standard 60-cell format using 182 mm half-cut cells. A 30 m² south-facing pitched roof can accommodate approximately 14–16 panels. The weight is compatible with standard aluminum racking systems, though for systems above 10 kW it is advisable to verify roof load capacity with a structural engineer. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/2400e7f88e51c4c320511fba689c0805-92ad8d1e9813.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +2.4 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +2.2 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +2.1 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +1.9 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +1.9 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, lighter, +1.9 pp | | [Leapton LP182\*182-M-60-NH-480W](https://comparepv.com/panel/leapton-lp182-182-m-60-nh-480w) | 480 W | -20 W, lighter, -0.9 pp | | [Leapton LP182\*182-M-60-NH-485W](https://comparepv.com/panel/leapton-lp182-182-m-60-nh-485w) | 485 W | -15 W, lighter, -0.7 pp | | [Leapton LP182\*210-M-54-NH-490W](https://comparepv.com/panel/leapton-lp182-210-m-54-nh-490w) | 490 W | -10 W, lighter, -0.5 pp | | [Leapton LP182\*182-M-60-NH-490W](https://comparepv.com/panel/leapton-lp182-182-m-60-nh-490w) | 490 W | -10 W, lighter, -0.4 pp | | [Leapton LP182\*182-M-60-NB-495W](https://comparepv.com/panel/leapton-lp182-182-m-60-nb-495w) | 495 W | -0.2 pp | | [Leapton LP182\*210-M-54-NH-495W](https://comparepv.com/panel/leapton-lp182-210-m-54-nh-495w) | 495 W | Lighter, -0.3 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +60 W, cooler, +2.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +55 W, cooler, +2.1 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +50 W, lighter, +1.8 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +40 W, cooler, +1.8 pp | --- Source: https://comparepv.com/panel/leapton-lp182-182-m-60-nb-500w 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.
