Middle of its segment, modest efficiency
The Hyundai YH Series Dual Black Max is a range of modules designed for maximum energy yield in environments where both aesthetics and stable production throughout the year are important. The use of bifacial construction allows for the utilization of light reflected from the ground, which in practice helps to increase yields in installations on bright roofs, terraces, awnings, and ground-mounted structures. Meanwhile, half-cut cells combined with multi-wire technology improve performance under partial shading and reduce losses due to microcracks and electrical resistance.
A key feature of this range is a full, deep all-black effect, which ensures that the installation looks consistent on modern roofs - without compromising between design and performance. The modules are designed to withstand harsh weather conditions, which will be appreciated by investors in Poland who are looking for solutions that are resistant to loads and daily use.
This is a good choice for single-family homes and commercial projects, where high performance, appearance, and real energy yield in variable lighting conditions are important.

Residential, commercial and shaded-installations.
Tight roof space, roofs where every square metre has to count and owners who want a long output guarantee.

Per the official HiS-SOOOYH datasheet, the rear surface contributes up to 25% additional power relative to the front. On high-albedo substrates (white membrane, gravel, concrete) and on carport or ground-mount structures, real annual energy gains of 5-10% over monofacial modules are achievable.
Half-cut cell technology halves internal current, cutting resistive losses by ~50% and reducing thermal stress. Multi-wire interconnect limits micro-crack propagation and improves partial-shading resilience - a meaningful advantage on residential pitched roofs with chimney or tree shading.
The series combines bifacial output with a true all-black appearance (black cells, black frame, black backsheet), a differentiator in the bifacial segment where most modules ship with silver frames or clear glass backs. No design-vs-yield compromise for modern residential or commercial rooftops.
Hyundai Energy Solutions (Tier-1 bankable, Seoul, founded 2004) backs the series with a 25-year product warranty and a 25-year linear power guarantee - full coverage over the entire typical residential or commercial PV system lifecycle with no mid-life warranty renegotiation required.
Maximum module efficiency caps at 20.5%, while peer comparable Luxor Eco Line N-type TOPCon reaches 21.33% (+0.83 pp, ~4% more power per m²) and Sunket SKT410 achieves 21.0%. On the same roof area a TOPCon module will deliver measurably more annual energy - the gap widens as available mounting space decreases.
The YH Series temperature coefficient is approximately -0.347%/°C (standard for PERC). Competing N-type TOPCon panels achieve -0.28 to -0.30%/°C, meaning lower thermal losses on hot summer days. At typical Polish summer module operating temperatures of 60-70°C, this translates to an additional 1.5-2% output loss vs. TOPCon peers.
- At 19.8% efficiency, this panel is 2.0pp below the database median of 21.8%
- 197.8 W/m² power density is 20.3 W/m² below database median (218.1 W/m²) - requires larger installation area
- Temperature coefficient of -0.35%/°C is 0.05pp worse than database median (-0.30%/°C) - higher losses in summer heat
- Weight of 21.1 kg (5.4 kg below database median of 26.5 kg) allows easier transport and roof mounting
- Ranked #12501 out of 14129 panels for efficiency in the database
