Light for its output, no clear weak spot
The Hyundai HeteroMax (LE-FB(ZB) Series) has been designed to maximize energy yield from every meter of roof area, even under less-than-ideal conditions. The use of N-type HJT cells ensures stable operation and excellent energy production even with lower sunlight levels, which is particularly important in the Polish climate, especially in autumn and winter. The modules utilize a dual glass construction, which enhances resistance to environmental factors and helps maintain performance over the long term. Another key feature is the full black aesthetic, which makes the series ideal for modern roofs where a consistent and aesthetically pleasing appearance is important.
The LE-FB(ZB) series is a good choice for investors who want to combine high efficiency with durability, whether in residential prosumer installations or in projects where consistent quality is essential. Thanks to improved performance at high temperatures and a refined cell connection technology, this series effectively reduces typical losses and helps extract more energy from the same surface area.

Signals from the data
Residential, commercial and hot-climate.
Top 11% of the HJT 450-500 W segment, against a median of 49.3.
Temperature coefficient of Pmax is -0.24%/°C — among the lowest in the 440-460 W module segment (PERC: approx. -0.35%/°C, TOPCon: approx. -0.28-0.30%/°C). N-type cell architecture fully eliminates LID (Light-Induced Degradation) and ensures zero PID sensitivity, delivering more stable energy yield across the full 30-year operating lifetime.
The symmetrical HJT cell structure enables a bifaciality factor of up to 90%, compared to ~70-75% for PERC and ~80-85% for TOPCon modules. At a typical ground albedo of 20% (light roofing or gravel), this translates to a 5-9% real-world power gain above the front-side STC rating, directly improving system LCOE.
Hyundai guarantees 90.3% of nominal power after 30 years alongside a 30-year product warranty. The industry standard for peer comparables (Risen RSM96-11, Zonergy ZPM MH3-72, SunKean SKT440-460M12) is a 25-year power warranty. The extended coverage significantly reduces investment risk in bank-financed projects.
The dual-glass construction (1.6 mm front and rear glass) eliminates UV-induced backsheet degradation and substantially reduces moisture ingress — critical in Central European climates with high diurnal temperature swings. The full-black finish provides a uniform appearance on modern pitched roofs with no visible contrast between cells and frame.
Top variants in the series reach 23% efficiency, matching Risen RSM96-11-440-460BNDG (23%) and SunKean SKT440-460M12-96D4 (23.02%), while exceeding Zonergy ZPM MH3-72 (21.16%) by nearly 1.84 percentage points. In terms of power per square meter, this translates to meaningfully higher output from the same roof area.
HJT modules are priced at approximately $0.38-0.50/W wholesale versus $0.28-0.35/W for TOPCon equivalents — a 15-40% premium. Peer comparables Risen RSM96-11 and SunKean SKT440-460M12, both TOPCon-based, achieve equal or marginally higher efficiency (23-23.02%) at a lower per-watt cost, which may favor the alternative in typical residential prosumer installations where minimizing BoS cost takes priority over maximizing power density.
- At 23.0% efficiency, this panel is on par with typical HJT 450-500W modules
- At 230.2 W/m² power density, roof space requirements are typical for HJT 450-500W panels
- At -0.24%/°C, hot weather performance is typical for HJT 450-500W panels
- 21.6 kg weight - 1.4 kg lighter than HJT 450-500W median (23.0 kg), reducing installation effort
- #1919 for efficiency, #13 for temperature performance out of 14005 panels
