The use of half-cut cells helps to minimize losses due to partial shading and reduces the risk of hot spots, which translates to more predictable yields in rooftop and ground-mounted installations. A key feature of this series is its **high mechanical durability**, as well as its refined module design (glass + backsheet) that makes installation in standard systems easier. Another advantage is **compatibility with long strings (1500 V system)**, which allows for more efficient cable and equipment design. In practice, this means fewer compromises when dealing with large module arrays. This is a sensible choice for investors who expect **consistent quality**, **uniform aesthetics (full black variants)**, and durability confirmed by industry standards. The LP182\*182-M-60-MH series is suitable for homes, businesses, and commercial projects where reliability, easy maintenance, and long-term performance are essential. ## Notable figures - At 20.8% efficiency, this panel is 1.7pp below the \*\*TOPCon 450-500W\*\* median of 22.5% - Power density of 207.9 W/m² is 17.3 W/m² below \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - needs more roof space - At -0.36%/°C, loses 0.07pp more power per degree than \*\*TOPCon 450-500W\*\* median (-0.29%/°C) - At 23.0 kg, weight matches the \*\*TOPCon 450-500W\*\* median - #10558 for efficiency, #12345 for temperature performance out of 14005 panels ## Questions ### What is the maximum power output of the Leapton LP182\*182-M-60-MH panel? The Leapton LP182\*182-M-60-MH reaches a peak power of 465 Wp in its top variant, with module efficiency around 21%. The TOPCon cell technology combined with a 120 half-cut cell layout (182×182 mm cells) delivers more energy from the same roof or ground area compared to standard PERC monocrystalline modules. It is a strong choice for installations where maximizing output per square meter is a priority. ### What warranty does the Leapton LP182\*182-M-60-MH come with? The manufacturer provides a 15-year product warranty covering material and workmanship defects, plus a 25-year linear power warranty. The power warranty guarantees that after 25 years of operation the panel will retain a defined percentage of its original rated output. These terms are standard for Tier 1 manufacturers and offer a solid foundation for calculating the long-term return on investment of a photovoltaic system. ### How does the LP182\*182-M-60-MH handle partial shading from a chimney or dormer window? The 120 half-cut cell layout significantly reduces losses under partial shading. Splitting each cell halves the internal current, minimizing the weak-link effect and lowering the risk of hot spots. In practice, the module maintains higher energy output even when a chimney, dormer, or antenna partially shades its surface — a key advantage for rooftop installations on residential buildings with complex roof geometry. ### Is the LP182\*182-M-60-MH series compatible with 1500 V DC systems? Yes, the LP182\*182-M-60-MH series is designed for 1500 V DC systems. The higher system voltage allows longer strings per MPPT input, which means fewer cables, fewer inverter MPPT trackers, and lower overall Balance of System (BoS) costs. This is especially beneficial in commercial and industrial installations where wiring optimization has a significant impact on total project cost. ### What is TOPCon technology used in the LP182\*182-M-60-MH series and is it worth choosing? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that achieves higher efficiency and a lower temperature coefficient than standard PERC cells through a tunnel oxide layer and passivated contacts. For system owners, this translates to more energy on hot summer days and better production in diffuse light conditions. In the LP182\*182-M-60-MH, TOPCon is combined with a half-cut layout, further improving shade tolerance and reducing thermal stress on individual cells. ### Is the Leapton LP182\*182-M-60-MH series still available for purchase? The LP182\*182-M-60-MH series has been discontinued. New shipments directly from the manufacturer are no longer available, and market availability is limited to existing distributor stock. If you need modules with similar specifications, consider newer Leapton series based on N-type TOPCon technology, which offer higher efficiency, higher unit power ratings, and extended power warranties of up to 30 years. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/0f16fffe1b6966397dd2b1079e096316-37298236d074.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, +4.0 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, +3.7 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +50 W, cooler, +3.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +50 W, cooler, +3.7 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +50 W, cooler, +3.7 pp | | [GCL GCL-NR10R/54BGDF](https://comparepv.com/panel/gcl-gcl-nr10r-54bgdf) | 500 W | +50 W, cooler, +3.7 pp | | [Leapton LP182\*182-M-60-MH-455W](https://comparepv.com/panel/leapton-lp182-182-m-60-mh-455w) | 455 W | +0.2 pp | | [Leapton LP182\*182-M-60-MH-460W](https://comparepv.com/panel/leapton-lp182-182-m-60-mh-460w) | 460 W | +10 W, +0.5 pp | | [Leapton LP182\*182-M-60-MH-465W](https://comparepv.com/panel/leapton-lp182-182-m-60-mh-465w) | 465 W | +15 W, +0.7 pp | | [Leapton LP182\*182-M-60-NB-470W](https://comparepv.com/panel/leapton-lp182-182-m-60-nb-470w) | 470 W | Cooler, +0.9 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +110 W, cooler, +4.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +105 W, cooler, +3.8 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +100 W, cooler, +3.6 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +90 W, cooler, +3.6 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +90 W, cooler, +3.6 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +95 W, cooler, +3.5 pp | --- Source: https://comparepv.com/panel/leapton-lp182-182-m-60-mh-450w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
