The use of **MBB (multi-busbar) technology** reduces resistive losses and improves energy harvesting, resulting in more reliable performance even when the installation is shaded or has less-than-ideal orientation. A key feature of this series is **high PID resistance**, which helps to better control performance degradation over time, giving investors predictable production. The modules also undergo **salt fog and ammonia corrosion tests**, making them suitable for environments with high levels of environmental aggression. In addition, they have **enhanced mechanical strength**, which is important in windy areas and during winter loads. This is a sensible choice for installers and investors looking for a series for residential, commercial, and PV farms, where energy yield, durability, and reduced risk of warranty claims are important. ## Notable figures - Efficiency of 20.9% is 1.8pp below the \*\*TOPCon 500-550W\*\* median (22.7%) - Power density of 208.9 W/m² is 18.5 W/m² below \*\*TOPCon 500-550W\*\* median (227.4 W/m²) - needs more roof space - Temperature coefficient of -0.36%/°C is 0.07pp worse than \*\*TOPCon 500-550W\*\* median (-0.29%/°C) - higher losses in summer heat - In the top 72% for efficiency among all TOPCon panels ## Questions ### Is the Leapton LP182\*182-M-72-MH series still available for purchase? The Leapton LP182\*182-M-72-MH series has been discontinued and is no longer part of the manufacturer's active lineup. If you need modules with similar characteristics — 182 mm half-cut monocrystalline cells with MBB technology — consider newer Leapton N-Type or TOPCon series, which offer higher efficiency and updated warranty terms. ### What warranty does the Leapton LP182\*182-M-72-MH series come with? Leapton provides a 15-year product warranty covering materials and workmanship, along with a 25-year linear power output warranty for the LP182\*182-M-72-MH series. After 25 years, the manufacturer guarantees at least 84.8% of rated power. This warranty scope is standard for a Tier 1 manufacturer headquartered in Japan and reflects the brand's proven track record. ### What does MBB technology do in the Leapton LP182\*182-M-72-MH series, and does it make a real difference? MBB (multi-busbar) technology replaces a few wide busbars with a greater number of thin ones. This shortens the current path across the cell surface, reducing resistive losses and improving collection of light reflected off the busbars. In practice, it translates to higher energy yield from the same module area, especially under diffuse light and overcast sky conditions. ### Do the Leapton LP182\*182-M-72-MH panels perform well in winter and overcast conditions? Yes. The half-cut cell design limits mismatch losses under partial shading, and the module operates across a temperature range of -40°C to +85°C. The power temperature coefficient is approximately -0.36%/°C, meaning that on a cold but sunny day the panel can produce more power than during a summer heatwave. Low-irradiance testing also confirms better performance under cloudy skies. ### What mechanical loads can the Leapton LP182\*182-M-72-MH modules handle — are they suitable for windy or snowy locations? The LP182\*182-M-72-MH modules have been mechanically tested by TÜV Nord and withstand a wind load of 2400 Pa and a snow load of 5400 Pa. This makes them well-suited for installations in climates where heavy snowfall and strong winds place significant stress on the roof structure and modules. ### Are the Leapton LP182\*182-M-72-MH 560W panels bifacial? No, the LP182\*182-M-72-MH series is a monofacial module — power is generated from the front side only. Leapton does offer bifacial variants within the 182 mm cell platform, but they carry a different model designation. For standard pitched-roof installations this is not a drawback, as the rear of the module is blocked by the mounting structure regardless. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/35d799aac0e1d2406bc7dfdb3b56cd1e-655be82413ea.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +4.1 pp, +5 yr warranty | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +3.9 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +3.9 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, +3.8 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.7 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +3.6 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, +3.6 pp, +5 yr warranty | | [Leapton LP182\*182-M-72-MH-545W](https://comparepv.com/panel/leapton-lp182-182-m-72-mh-545w) | 545 W | Very close match | | [Leapton LP182\*182-M-72-MH-550W](https://comparepv.com/panel/leapton-lp182-182-m-72-mh-550w) | 550 W | +10 W, +0.4 pp | | [Leapton LP182\*182-M-72-MH-555W](https://comparepv.com/panel/leapton-lp182-182-m-72-mh-555w) | 555 W | +15 W, +0.6 pp | | [Leapton LP182\*182-M-72-MH-560W](https://comparepv.com/panel/leapton-lp182-182-m-72-mh-560w) | 560 W | +20 W, +0.8 pp | | [Leapton LP182\*182-M-72-NB-565W](https://comparepv.com/panel/leapton-lp182-182-m-72-nb-565w) | 565 W | Cooler, heavier, +5 yr warranty | | [Leapton LP182\*199-M-66-NH 570W](https://comparepv.com/panel/leapton-lp182-199-m-66-nh-570w) | 570 W | Cooler, +1.2 pp, +5 yr warranty | | [Leapton LP182\*199-M-66-NH 575W](https://comparepv.com/panel/leapton-lp182-199-m-66-nh-575w) | 575 W | Cooler, +1.4 pp, +5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +110 W, cooler, +4.3 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +105 W, cooler, +4.1 pp | --- Source: https://comparepv.com/panel/leapton-lp182-182-m-72-mh-540w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
