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.

What owners get
Bifacial design - up to 25% rear-side gain

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.

132 half-cut cells + multi-wire interconnect

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.

Full all-black aesthetic (Dual Black Max)

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.

25-year product + 25-year power warranty

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.

Trade-offs
PERC technology vs. N-type TOPCon peers

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.

Higher temperature coefficient than TOPCon

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.

About the YH Series Dual Black Max series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

Do Hyundai YH Series Dual Black Max panels actually produce more energy thanks to their bifacial design?
Yes. The bifacial construction of the YH Series Dual Black Max allows cells to capture both direct front-side irradiance and light reflected off the mounting surface from the rear. When installed over a light-colored roof, terrace, or ground-mount with a reflective surface, you can gain between a few percent and up to 25% additional energy compared to a standard monofacial module. The brighter and more reflective the surface beneath the array, the greater the bifacial gain.
What is the warranty on Hyundai YH Series Dual Black Max panels and how much power will they retain after 25 years?
The YH Series Dual Black Max comes with a 25-year product warranty covering defects in materials and workmanship, plus a 25-year linear power warranty. Degradation is capped at 2% in year one and no more than 0.25% per year thereafter, guaranteeing that after 25 years the module retains at least 85% of its rated output power.
Does the Hyundai YH Series Dual Black Max truly look all-black on a modern roof?
Yes. A black anodized aluminum frame, black PERC cells, and a black backsheet combine to deliver a deep, uniform all-black appearance with no contrasting metallic elements to break the visual line. The result is a clean look on both pitched and flat rooftops. This makes the series a popular choice for homeowners and architects who require high aesthetics alongside strong energy performance.
How do Hyundai YH Series Dual Black Max panels perform under partial shading from a chimney or antenna?
The combination of half-cut cell technology and multi-wire busbars makes the YH Series Dual Black Max significantly more resilient to partial shading than conventional full-cell modules. Splitting each cell in half reduces resistive losses and electrically isolates shaded sections from the rest of the module. The IP67-rated junction box with bypass diodes further minimizes hot-spot effects and mitigates the risk of micro-cracks caused by localized power dissipation.
What is the maximum power output and efficiency of the Hyundai YH Series Dual Black Max?
The top model in the series delivers 410 Wp at a module efficiency of up to 20.5% - strong figures for PERC technology. The series spans from 385 Wp to 410 Wp, giving installers flexibility to optimize array sizing for available roof area. Higher efficiency translates directly to more kilowatts per square meter, which is a meaningful advantage on rooftops with limited usable space.
Is Hyundai a reliable solar panel manufacturer worth trusting for a 25-year warranty commitment?
Hyundai Energy Solutions is a South Korean manufacturer classified as Tier 1 by Bloomberg NEF, confirming its financial bankability and stable long-term market presence. Tier 1 status matters to end customers because it increases the likelihood the manufacturer will remain operational throughout the full 25-year warranty period. The brand maintains a global distribution and service network alongside a well-documented quality control process at the production level.
