Hyundai YH SERIES Dual Black Max photovoltaic panels are an advanced solution combining bifacial half-cut cell technology with uncompromising premium aesthetics. This series stands out through the use of a unique black mesh on a transparent film, which allows for a deep black effect while maintaining the bifaciality of the module. As a result, investors gain additional energy yield from reflected light without sacrificing the elegant appearance of the roof. These modules effectively solve the problem of limited efficiency in low-light conditions, offering stable operation even under heavy cloud cover. The exceptional Dual Black aesthetics make them an ideal choice for modern residential construction, where the appearance of the installation is just as important as its parameters. They are distinguished from the competition by increased resistance to LID and PID degradation and an exceptionally solid construction that easily withstands extreme snow and wind loads. This series provides maximum reliability confirmed by a 25-year warranty on the product and performance, which, combined with the reputation of a global brand, guarantees investment security. This product is dedicated to those seeking components of the highest durability, where multi-busbar technology minimizes energy losses, translating into a faster return on the photovoltaic system investment.

What owners get
Dual Black aesthetics with bifaciality

A proprietary black grid printed on a transparent backsheet delivers a full-black appearance while retaining bifacial capability - rear-side power gain reaches up to 25% of front-side output (at ~20% ground albedo). This combination is unavailable in conventional all-black monofacial modules.

Half-cut multi-busbar technology (132 cells)

Splitting cells in half reduces operating current by 50%, lowering resistive I²R losses and improving shading tolerance. Multi-wire (multi-busbar) interconnection shortens current paths within each cell, reducing microfracture risk and improving low-irradiance yield under diffuse light conditions.

25-year product and power warranty

The manufacturer guarantees a minimum of 85% of nominal power after 25 years (linear degradation of 0.54%/year after year one), in line with premium-segment standards. The matching 25-year product warranty covers manufacturing defects throughout the full operational lifecycle.

BNEF Tier-1 bankable manufacturer

Hyundai Energy Solutions (founded 2004, HQ South Korea) holds BNEF Tier-1 bankable status, enabling project financing from financial institutions without additional module-level due diligence - a critical factor for commercial and debt-financed PV installations.

Mechanical robustness - extreme load ratings

An alloy 6063 aluminum frame and 3.2 mm AR-coated tempered glass provide certified resistance to snow and wind loads (IEC 61215:2016, 40 mm hailstone test per Kiwa PVEL), qualifying the series for deployment in high-snow-load climate zones.

Trade-offs
Series discontinued (2024)

The YH Dual Black Max series was discontinued in 2024. Availability is limited to dealer clearance inventory (A1 SolarStore, Greentech Renewables). No datasheet revisions will be issued, and module-for-module warranty replacements may be unavailable once distributor stock is exhausted.

P-type PERC - lower efficiency vs. N-type peers

The P-type PERC cell architecture caps module efficiency at 20.5% at 410 Wp. A direct comparable - the Luxor Eco Line N-type TOPCon (410-430 W) - achieves 21.33% at identical peak power, while the Sunket SKT430M10 reaches 21.0%. The ~0.8-1.0 pp gap translates to measurably lower kWh/m² yield on the same roof area.

Higher annual degradation vs. N-type

The rated 0.54%/year degradation (P-type PERC) exceeds the 0.40-0.50%/year typical of N-type TOPCon modules. Over 25 years, the guaranteed floor is 85% of nameplate power, versus >90% retained by TOPCon alternatives - a cumulative generation gap of approximately 5-8 percentage points over the module's service life.

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.

Are Hyundai YH SERIES Dual Black Max panels still available for purchase?
The Hyundai YH SERIES Dual Black Max has been discontinued and is no longer manufactured by Hyundai Energy Solutions. Limited stock may still be available through select distributors. If you require a similar bifacial, premium-aesthetic module, ask your dealer about a current equivalent within Hyundai's lineup or from another Tier 1 manufacturer.
What does bifacial technology mean in the Hyundai YH SERIES Dual Black Max and how much extra energy can I expect?
A bifacial module generates electricity from both its front and rear surfaces by capturing light reflected off the ground, rooftop, or surroundings. Real-world rear-side gain depends on surface albedo and tilt angle. With a light-colored rooftop or gravel, you can realistically expect 5-15% additional annual energy yield compared to a conventional monofacial panel of the same 410 Wp rated output.
Why does the Dual Black series look like a fully black panel even though it is bifacial?
Hyundai uses a unique black grid printed on a transparent backsheet instead of the standard white or clear layer. This creates a deep all-black appearance when viewed from street level while keeping the rear surface sufficiently transparent for reflected-light capture. The result is the aesthetics of a traditional all-black module combined with the energy benefits of bifacial technology.
Do the Hyundai YH SERIES Dual Black Max 410 W panels perform well in winter and cloudy conditions?
Yes. The half-cut cell design reduces internal resistance and limits the impact of partial shading, improving performance at low winter sun angles. Hyundai rates these modules for stable output under diffuse irradiance. Cold temperatures also inherently benefit silicon cell efficiency, making clear, frosty days among the most productive periods for this series.
What warranty comes with the Hyundai YH SERIES Dual Black Max and what does it cover?
Hyundai provides a 25-year product warranty covering material and workmanship defects, plus a 25-year linear power output warranty guaranteeing the panel retains approximately 80-82% of its nominal power after 25 years of operation. As a Tier 1 manufacturer headquartered in South Korea, Hyundai adds credibility to the long-term financial standing behind these warranty commitments.
What are LID and PID resistance, and why do they matter in the YH SERIES Dual Black Max?
LID (Light-Induced Degradation) is the power drop that occurs in the first hours of illumination, while PID (Potential-Induced Degradation) is caused by voltage differentials across the module structure. The YH SERIES Dual Black Max uses optimized cell passivation and encapsulant materials to minimize both effects, reducing real-world power loss from year one and delivering higher LCOE performance over the full 25-year warranty period.
