Hyundai DG G12 PERC Shingled (HiE-S___DG) modules are designed for high yield per square meter and stable performance under real roof conditions. The use of monocrystalline PERC cells in shingled technology enables a denser arrangement of the active surface and reduces connection losses - translating to better energy production even in low sunlight conditions or when parts of the roof are shaded.

In practice, this series addresses a common challenge for investors: how to extract more from a limited surface area without compromising quality. The modules are designed for longevity - the reinforced structure and tempered glass enhance resistance to snow, wind, and demanding climates. Another distinguishing feature is resistance to PID and limitation of the LID effect, which helps maintain predictable yields over the long term.

This is an excellent choice for single-family homes and small commercial installations where aesthetics matter - in multiple variants, a full black appearance is available, tailored to modern roofs.

What owners get
Efficiency at segment top

The DG G12 series achieves 20.9-21.4%; the 425 Wp variant matches Tongwei TERRA 5K (21.4%) and outperforms Trina Solar Vertex S (21.3%). For a monofacial PERC module, this places the series at the very top of the available product segment.

Busbar-free shingled architecture

Shingled cell interconnection eliminates resistive losses from conventional PERC tabbing. Research (Klasen et al., Progress in Photovoltaics, 2022) confirms improved behavior under partial shading compared to standard half-cut PERC designs - a meaningful advantage in residential rooftop installations with chimneys or dormers.

Full-black aesthetics (DG series)

The series features a complete full-black appearance (black frame, black backsheet), differentiating it from standard white-backsheet modules. It is a strong choice for visible rooftop installations in residential settings where module aesthetics influence purchasing decisions.

Tier-1 manufacturer, 25-year warranty

Hyundai Energy Solutions is recognized on BNEF Tier-1 lists (South Korea, est. 2004), ensuring bankability in non-recourse project financing. Both the product warranty and linear power warranty span 25 years, guaranteeing no less than 84.8% of rated power output at end of term.

Trade-offs
Discontinued series (EOL: 2024)

Hyundai ended production of the DG G12 PERC Shingled series in 2024 (released 2022). Replacement module availability on the market is limited and will continue to shrink, posing a real risk of incompatible replacements for expansion or failure scenarios within the 25-year warranty period.

Monofacial design vs. bifacial peer

Peer comparable DAS Solar DAON mini Bifacial Double Glass reaches 425 Wp at 21.8% efficiency (+0.4 pp vs. Hyundai DG) and generates an additional 5-25% energy yield from albedo reflection (per IEC TS 60904-1-2). As a monofacial module, the Hyundai DG forfeits this energy advantage even at identical rated power.

P-type PERC vs. N-type TOPCon standard

P-type PERC exhibits higher LID (Light-Induced Degradation, up to ~2% in year one) and a less favorable temperature coefficient TKPmax (~-0.35%/°C) compared to N-type TOPCon modules (~-0.29%/°C), which became the market standard in the 415-425 Wp segment in 2024. Over a full 25-year LCOE horizon, the difference in annual energy yield may reach 1-2%.

About the DG G12 PERC Shingled (HiE-S___DG) series

6 answered

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

Is the Hyundai DG G12 PERC Shingled series (HiE-S___DG) still available for purchase?
The Hyundai DG G12 PERC Shingled series (HiE-S___DG) has been discontinued and is no longer in active production by Hyundai Energy Solutions. Availability depends solely on distributor inventory - some warehouses may still carry remaining stock. Before purchasing, confirm current inventory levels and verify that warranty support can still be provided by a local authorized partner.
What does shingled technology mean in Hyundai HiE-S___DG panels, and why is it better than standard PERC?
Shingled technology overlaps cells and bonds them with conductive adhesive instead of conventional busbars. This eliminates solder joints prone to micro-cracking, reduces resistive losses, and maximizes the active cell area within the module. Combined with monocrystalline PERC cells, the result is higher power density per square meter and improved performance under partial shading compared to standard full-cell PERC modules.
What warranty does the Hyundai HiE-S___DG series carry, and what does it cover?
The HiE-S___DG series comes with a 25-year product warranty covering materials and workmanship, plus a 25-year linear power output warranty, as stated in the manufacturer's datasheet. Full 25-year product warranty terms applied specifically to the European and Australian markets. This warranty level is consistent with Tier 1 manufacturer standards. Always confirm current warranty terms with your local distributor before purchase.
Do Hyundai DG G12 PERC Shingled panels perform well under partial shading or on overcast days?
Yes. The combination of PERC cells and shingled architecture reduces resistive losses and increases active cell area, improving energy production in diffuse light and low-irradiance conditions. The series also features PID resistance and reduced LID effect, which helps maintain stable and predictable yields throughout the system's lifetime - a meaningful advantage on rooftops with chimneys, dormers, or nearby trees causing intermittent shading.
What is the maximum power output of the Hyundai HiE-S___DG series, and how many panels are needed for a typical residential system?
The top model in the series is rated at 425 Wp (HiE-S425DG). A typical 5 kWp residential system requires approximately 12 modules. At dimensions of 1,812 × 1,096 × 30 mm and a weight of approximately 20.8 kg per panel, the series is practical for standard sloped roofs. Module efficiency reaches approximately 21.4%, delivering more watts per square meter than most conventional PERC modules.
Are Hyundai HiE-S___DG modules available in a full black version, and do they suit modern roof aesthetics?
Yes, the DG G12 series was offered in a Full Black (FB) variant featuring an all-black frame and black backsheet for a uniform, minimalist appearance. This makes it a popular choice for single-family homes where roof aesthetics matter. Note that full black panels may operate at slightly higher cell temperatures during peak summer conditions, resulting in a minor power derating on the hottest days.
