Given the 30-year power warranty, the shorter market history may raise minor concerns about long-term warranty support despite the current bankable Tier-1 status. ## About this series The Leapton LP182\*199-M-66-NB panel series is a technologically advanced solution based on **N-type TOPCon cells**, which sets new standards for efficiency in the Polish climate. These modules solve the problem of power loss over time, offering significantly lower annual degradation than traditional P-type solutions. Thanks to the use of **glass-glass construction and bifacial technology**, these panels allow for harvesting additional energy from both sides of the module, which is crucial for ground-mounted installations and carport structures. The innovative **Super Multi-Busbar (SMBB)** layout optimizes the current flow path, minimizing resistive losses and increasing resistance to cell micro-cracks. This product is dedicated to investors seeking maximum return on capital, as it features **excellent efficiency in low sunlight**, which in our weather conditions translates into realistically higher yields on cloudy days. They are distinguished from the competition by exceptional resistance to ammonia corrosion and salt mist, allowing for safe installation near agricultural farms. The LP182\*199-M-66-NB series is the choice for professionals who rely on a **30-year linear power warranty** and components designed for trouble-free operation in the most demanding industrial and domestic environments. ## Notable figures - At 22.6% efficiency, this panel is on par with typical \*\*TOPCon 550-600W\*\* modules - At 226.4 W/m² power density, roof space requirements are typical for \*\*TOPCon 550-600W\*\* panels - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - #3600 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### What warranty does the Leapton LP182\*199-M-66-NB series come with? The LP182\*199-M-66-NB series includes a 25-year product warranty covering material and manufacturing defects, along with a 30-year linear power output warranty. The linear guarantee means the power degradation follows a predictable schedule with no sudden drops — giving investors a reliable baseline for ROI calculations over the system's lifetime. This is among the longest warranty packages available in the market today. ### How does TOPCon technology in the Leapton LP182\*199-M-66-NB differ from standard PERC? The N-type TOPCon cells used in the LP182\*199-M-66-NB series feature an ultra-thin passivating contact layer deposited directly on the silicon substrate, drastically reducing carrier recombination. Compared to conventional P-type PERC, this translates to lower annual degradation rates and better low-light performance — a critical advantage in climates with frequent overcast days, such as in Central and Northern Europe. ### Does the bifacial design of the Leapton LP182\*199-M-66-NB make sense for a ground-mounted system? Yes, especially when the ground surface is light-colored or covered with gravel. The glass-glass bifacial construction captures reflected irradiance from the rear side of the module, which can add several percentage points to annual yield depending on surface albedo. Bifacial gain is also effective in carport structures with open ground below. On dark roofing membranes the gain is minimal, though the glass-glass build still improves long-term mechanical and electrical durability. ### What is the peak power of a single LP182\*199-M-66-NB panel, and how many modules are needed for a 50 kWp system? The top-rated module in the LP182\*199-M-66-NB series reaches 590 Wp. For a 50 kWp installation, approximately 85 panels are required (50,000 ÷ 590 ≈ 84.7). The high per-module wattage reduces the total module count, lowers racking and BoS costs, and shortens installation time — all factors that meaningfully improve the overall LCOE of larger ground-mounted PV systems. ### Are the Leapton LP182\*199-M-66-NB panels safe to install near poultry farms or coastal areas? Yes. The LP182\*199-M-66-NB series is certified for resistance to both ammonia corrosion — relevant for livestock and agricultural environments — and salt mist exposure in coastal or marine climates. The sealed glass-glass encapsulation also makes the modules less susceptible to moisture ingress than conventional backsheet designs, making this series a reliable choice for demanding industrial, agricultural, and seaside installations. ### Is Leapton a reliable manufacturer, and where is the company headquartered? Leapton Energy is headquartered in Japan and is independently rated as a Tier 1 PV manufacturer, confirming its financial stability and proven large-scale production capacity. Tier 1 status is particularly important when seeking project financing or equipment leasing, as most banks and financial institutions require modules sourced from Tier 1 manufacturers as a condition of funding approval. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/2be159539ac20e7ec41f7c24b9966a14-6aa58ab369d8.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.0 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +50 W, lighter, +2.0 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +45 W, cooler, +1.8 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, 16 kg lighter, +1.8 pp | | [Leapton LP182\*182-M-72-MH-540W](https://comparepv.com/panel/leapton-lp182-182-m-72-mh-540w) | 540 W | Hotter, lighter, -1.7 pp | | [Leapton LP182\*182-M-72-MH-545W](https://comparepv.com/panel/leapton-lp182-182-m-72-mh-545w) | 545 W | Hotter, lighter, -1.6 pp | | [Leapton LP182\*182-M-72-MH-550W](https://comparepv.com/panel/leapton-lp182-182-m-72-mh-550w) | 550 W | Hotter, lighter, -1.4 pp | | [Leapton LP182\*182-M-72-MH-555W](https://comparepv.com/panel/leapton-lp182-182-m-72-mh-555w) | 555 W | Hotter, lighter, -1.2 pp | | [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 | -20 W, -0.8 pp | | [Leapton LP182\*199-M-66-NH 570W](https://comparepv.com/panel/leapton-lp182-199-m-66-nh-570w) | 570 W | -15 W, lighter, -0.6 pp | | [Leapton LP182\*199-M-66-NH 575W](https://comparepv.com/panel/leapton-lp182-199-m-66-nh-575w) | 575 W | -10 W, lighter, -0.4 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +65 W, lighter, +2.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +60 W, lighter, +2.4 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +55 W, lighter, +2.2 pp | --- Source: https://comparepv.com/panel/leapton-lp182-199-m-66-nb-585w 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.
