Light for its output, no clear weak spot
The Leapton LP182*199-M-66-NH series is an advanced solution based on N-type TOPCon cells, which are a response to growing demands for efficiency in challenging lighting conditions. Thanks to the use of this technology, the modules offer a significantly lower annual degradation rate compared to traditional P-type panels, guaranteeing stable energy yields for decades. The design utilizing half-cut technology effectively minimizes power losses caused by partial shading and reduces internal resistance, which directly translates into higher efficiency for the entire photovoltaic system. These models stand out with exceptional performance in low-light conditions, which in the Polish climate allows for effective power generation even under heavy cloud cover. This series solves key investor problems by offering a better temperature coefficient, thanks to which the modules lose less power during hot days. It is a product dedicated to both large-scale farms and modern commercial installations, where maximizing power density per square meter is essential. Leapton focuses on durability and innovation, delivering modules with high mechanical resistance, which sets them apart from standard solutions and ensures a faster return on investment for the most demanding users.
Ranking
Signals from the data
Commercial, utility-scale, shaded-installations and hot-climate.
Top 14% of the TOPCon 550-600 W segment, against a median of 53.8.
N-type TOPCon cells deliver lower LID/LeTID degradation and a better power temperature coefficient (-0.3%/°C) than legacy P-type PERC modules, translating into higher and more stable energy yield, especially on hot days.
Module efficiency reaching 22.83% places the series among the segment's top performers, on par with Talesun TM7G72M (22.8%) and Horay Solar HS 182-144 TC-D (22.8%), maximizing power output from limited roof or land area.
The manufacturer guarantees a minimum of 87.4% of rated power after 30 years, backed by a 25-year product warranty — a premium-tier standard for TOPCon modules that ensures predictable, long-term investment returns.
Half-cut cell technology (132 cells) reduces power loss from partial shading and lowers the module's internal resistance, boosting overall system performance, particularly under variable irradiance conditions.
Leapton holds BNEF Tier-1 status (bankability confirmed via non-recourse project finance), and the series' 5 power variants spanning 570-590 Wp allow flexible fitting for utility-scale and commercial installations.
Unlike comparable peer series (Talesun TM7G72M BIPRO and Horay Solar HS 182-144 TC-D Ocean), which offer bifacial modules, the NH variant of this Leapton series is monofacial, forfeiting the additional rear-side energy gain available in ground-mount or high-albedo tracker installations.
