This means a slightly larger module area is needed to reach the same power output, which may matter on roofs with limited surface area. ## About this series The Leapton LP182\*182-M-60-NB series are **N-type bifacial** modules in a **half-cut** format, designed to maximize energy output from the same installation area - especially when conditions are not ideal. Thanks to N-type cells (often associated with TOPCon technology), these panels offer **improved performance in low-light conditions** and slower degradation of parameters over time, which translates to more stable production in the Polish climate. The **dual glass** construction enhances durability and resistance to harsh environments, while the bidirectional energy harvesting allows for the utilization of reflected light - which is important on bright roofs, gravel, membranes, or when mounted on the ground. The use of multi-busbar cells (MBB) helps to reduce losses and improve reliability in partially shaded conditions. This is a good choice for investors who want **higher annual yields** without increasing service risks - from single-family homes to small and medium-sized commercial installations. ## Notable figures - At 21.9% efficiency, this panel is 0.6pp below the \*\*TOPCon 450-500W\*\* median of 22.5% - At 219.4 W/m², this panel generates 5.8 W/m² less per unit area than \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 450-500W\*\* panels - At 26.5 kg, this panel is 2.5 kg heavier than the \*\*TOPCon 450-500W\*\* median (24.0 kg) - more demanding for installation crews - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### How does the Leapton LP182\*182-M-60-NB perform in low-light conditions and cold temperatures? The N-type TOPCon cell technology delivers better output in overcast and diffuse-light conditions compared to older PERC modules. The power temperature coefficient is -0.30%/°C, meaning lower losses on hot days. For the Polish climate with frequent cloudy periods, this translates into measurably higher annual energy yield versus previous-generation panels. ### What warranties does the Leapton LP182\*182-M-60-NB series carry? The manufacturer provides a 25-year product warranty covering manufacturing defects and a 30-year power warranty guaranteeing at least 87.4% of rated output. Annual degradation for N-type cells is approximately 0.4%, significantly better than the typical 0.55% for PERC modules, resulting in more stable production over the full system lifetime. ### What real benefit does the bifacial design of the LP182\*182-M-60-NB offer, and when does it pay off? The bifacial dual glass construction captures an additional 5–25% of energy from light reflected off the ground or roof surface. Gains are highest for ground-mounted systems, light-colored roofing membranes, and gravel substrates. On a typical dark roof tile the bifacial gain will be lower — this should be factored into yield calculations before purchase. ### Can the Leapton LP182\*182-M-60-NB be installed on a standard pitched roof? Yes. The module measures 1909 × 1134 × 30 mm and weighs 26.5 kg. Wind load resistance of 2400 Pa and snow load capacity of 5400 Pa (TÜV Nord certified) are adequate for Central European climate conditions. The dual glass construction is heavier than standard foil-backed modules — verifying the roof's structural load capacity is recommended, especially on older buildings. ### Is Leapton a Tier 1 manufacturer, and is the warranty secure? Leapton Solar is rated Tier 1 by leading PV industry agencies and is headquartered in Japan with its own production facilities, which supports standardized warranty procedures. To ensure warranty claims are handled efficiently, confirm that your local distributor holds an active service agreement with the manufacturer before purchasing. ### Is the LP182\*182-M-60-NB series suited for residential homes or commercial installations? At 480 Wp peak power, this series works well in residential prosumer systems (e.g., 10–20 kWp) as well as small and mid-size commercial installations. The half-cut layout with 120 cells using 182 mm wafers improves energy yield under partial shading — particularly useful wherever the roof or ground array is subject to shadows from chimneys, dormers, or adjacent structures. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/6737c549ff7dd6ee2e6d80d1e2dcc28f-04ee5ee0df21.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +35 W, cooler, +3.1 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +2.9 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +30 W, cooler, +2.8 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +2.6 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +2.6 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, lighter, +2.6 pp | | [Leapton LP182\*182-M-60-MH-450W](https://comparepv.com/panel/leapton-lp182-182-m-60-mh-450w) | 450 W | Hotter, -1.2 pp, -5 yr warranty | | [Leapton LP182\*182-M-60-MH-455W](https://comparepv.com/panel/leapton-lp182-182-m-60-mh-455w) | 455 W | Hotter, -0.9 pp, -5 yr warranty | | [Leapton LP182\*182-M-60-MH-460W](https://comparepv.com/panel/leapton-lp182-182-m-60-mh-460w) | 460 W | Hotter, lighter, -5 yr warranty | | [Leapton LP182\*182-M-60-MH-465W](https://comparepv.com/panel/leapton-lp182-182-m-60-mh-465w) | 465 W | Hotter, lighter, -5 yr warranty | | [Leapton LP182\*182-M-60-NB-470W](https://comparepv.com/panel/leapton-lp182-182-m-60-nb-470w) | 470 W | -0.2 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +85 W, cooler, +2.9 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +80 W, cooler, +2.7 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +75 W, lighter, +2.5 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +65 W, cooler, +2.5 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +65 W, cooler, +2.5 pp | --- Source: https://comparepv.com/panel/leapton-lp182-182-m-60-nb-475w 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.
