Solid all-round for its segment
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.
Ranking
Signals from the data
Commercial, utility-scale and shaded-installations.
TOPCon technology delivers lower LID/LeTID degradation and better high-temperature performance than legacy P-type PERC cells, translating into higher real-world annual energy yield, especially during summer months.
Dual-glass bifacial modules capture additional energy from the rear side (typically several to low-double-digit percent gain), making them especially cost-effective for ground-mount installations and carport structures over reflective surfaces.
The manufacturer guarantees a minimum of 87.4% nominal power after 30 years - a standard on par with top peer comparables (e.g. AE Solar HORIZON CMD-144BDS) and well ahead of typical 25-year warranties on older P-type modules, which degrade to around 80-84.8%.
Increased busbar count reduces resistive losses and improves resistance to cell microcracks, enhancing long-term power stability under mechanical stress such as snow load and wind.
Certified resistance to agricultural and coastal environments allows safe installation near livestock farms and in coastal zones, a feature not always offered by mass-market competing series.
Leapton Energy was founded in 2012, making it a younger player compared to Tier-1 industry leaders (e.g. Trina Solar - 1997, JinkoSolar - 2006). 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.
- 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

Measured curves published by Leapton in this model's datasheet. A chart carrying a wattage was measured on that variant alone - only the ones that describe 585 Wp appear here. The rest cover the whole series.
Simulations
Degradation from this panel's own datasheet figures. No inverter, soiling or shading losses.
Model: bifaciality × albedo × 0.6 view factor. A first-order estimate, not a yield simulation.
