Independent research (solarbuy.com) shows shingled panels deliver 5-15% higher energy yield than standard full-cell panels under partial shading conditions. - **20.7-21.4% efficiency within PERC class** - The maximum module efficiency of 21.4% places the HG Series at par with the best monofacial PERC panels in the segment - e.g. SunEvo SE6-46SC EVOX (21.4%). Typical monofacial PERC half-cut panels released in 2021-2023 ranged from 20-21%, meaning the HG Series sat at the upper boundary of what the technology generation could achieve. - **Anti-LID / anti-PID + 25-year linear power warranty** - The official datasheet (06/2022) confirms LID and PID degradation is eliminated and specifies a linear power guarantee with ≤0.55%/year degradation rate, yielding a guaranteed 84.8% of nameplate power after 25 years. This aligns with the best Tier-1 PERC warranties available and supports long-term LCOE calculations for self-consumption-oriented systems. - **Tier-1 bankable manufacturer (Hyundai Energy Solutions)** - Hyundai Energy Solutions carries Tier-1 bankable status, meaning modules are accepted as collateral by project-finance banks and institutional lenders. For commercial installations or residential systems financed through loans or leasing, this classification meaningfully reduces project risk. - **Reinforced build + full black variant** - Tempered glass and a reinforced frame enable installation in demanding climatic zones (snow and wind loads). The full black variant (HiE-S430-445HG FB) addresses growing demand for aesthetically integrated systems on modern rooftops, without any nameplate power compromise. ## Cons - **Discontinued series (since 2023)** - The HG G12 PERC Shingled series ended production in 2023. This results in limited availability of new units on the market, risk of incompatible modules for system expansion, and potential difficulties in fulfilling warranty service claims and sourcing replacement components over the long term. - **Lower efficiency vs. next-gen peer comparables** - Direct comparables at the same 445 W power class achieve substantially higher module efficiency: Q-Cells Q.TRON BLACK at 22.3% and Solitek SOLRIF D Satin at 22.06% - a gap of 0.9-1.0 percentage points translating to approximately 4-5% less energy output from the same roof area, which is meaningful on space-constrained installations. - **Monofacial only - no bifacial gain** - The module is strictly monofacial (is\_bifacial: false), forgoing albedo-reflected irradiance. In ground-mount and flat-roof BoS configurations, bifacial equivalents typically harvest an additional 5-15% annual energy without increasing the installation footprint. ## About this series Hyundai HG G12 PERC Shingled (HG Series) modules are designed for maximum yield where every square foot of roof space counts. The applied **shingled PERC technology** minimizes gaps between active cell areas and improves performance under partial shading - instead of sudden power drops, the installation maintains a more stable output in real-world conditions. Additionally, the construction is geared towards long-term predictability: **anti-LID and anti-PID protection** helps maintain higher efficiency for years, which is especially important for systems focused on self-consumption and detailed production tracking over the long term. The modules are also distinguished by **reinforced frame and tempered glass**, facilitating selection for more challenging weather conditions and demanding installation zones. For investors valuing aesthetics, full black variants are available, perfectly matching modern roofs. This is the series for homes and businesses seeking high power density, durability, and trouble-free operation without surprises. ## Notable figures - At 20.9% efficiency, this panel is on par with typical \*\*PERC 400-450W\*\* modules - At 209.0 W/m² power density, roof space requirements are typical for \*\*PERC 400-450W\*\* panels - Temperature coefficient of -0.34%/°C matches the \*\*PERC 400-450W\*\* median - #10148 for efficiency, #8846 for temperature performance out of 14129 panels ## Questions ### What makes the shingled PERC technology in Hyundai HG G12 panels better than standard PERC modules? In shingled modules, PERC cells overlap and are bonded with conductive adhesive instead of traditional busbars. This increases the active surface area and reduces resistive losses. In the HG G12 series this translates to up to 21.4% module efficiency and up to 445 W from a 1,899×1,096 mm footprint. The architecture also reduces string-level losses under partial shading because there are no busbars acting as current bottlenecks. ### How do Hyundai HG Series panels perform in winter and on overcast days? Cold temperatures actually benefit PV modules - the HG G12 power temperature coefficient is -0.34%/°C, meaning output rises slightly below 25°C STC. On cloudy days, PERC technology improves performance in diffuse light through the reflective rear passivation layer. The series handles year-round conditions well, including climates with frequent overcast periods typical of Central and Northern Europe. ### What warranty does the Hyundai HG G12 PERC Shingled series carry, and how much power is guaranteed after 25 years? Hyundai backs the HG G12 series with a 25-year product warranty covering materials and workmanship, plus a 25-year linear power warranty guaranteeing at least 84.8% of rated output after 25 years. Built-in anti-LID and anti-PID protection helps slow long-term degradation, supporting predictable energy yields over the system's full lifespan. ### Are Hyundai HG Series panels available in a full black version, and does it affect efficiency? Yes, the HG G12 series was offered in a full black variant - black frame and black backsheet - for a clean, uniform look that pairs well with dark roof tiles or standing-seam metal roofs. Efficiency in the full black variant is comparable to the standard black-frame/white-backsheet version, so the choice is purely aesthetic and depends on roof type rather than any meaningful difference in energy yield. ### Are Hyundai HG G12 PERC Shingled panels still available for purchase? The HG G12 PERC Shingled series has been discontinued and is no longer in standard production. Some distributor stock may still be available, so it is worth checking directly with local suppliers. If you are looking for Hyundai shingled or PERC modules, reviewing the manufacturer's current active lineup may reveal newer options with higher performance ratings. ### Do the Hyundai HG G12 panel dimensions (1,899×1,096 mm) fit standard racking systems, and how heavy is each module? HG G12 modules measure 1,899×1,096×30 mm and weigh 21.8 kg each. The G12 format is slightly larger than older M10-based modules but is compatible with most standard rail racking systems used on pitched and flat roofs. A two-person installation crew can handle the weight comfortably on residential projects, though larger commercial installations should plan for appropriate on-roof material handling. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HYUNDAI-G12-HiE-SxxxHG-BlackFrame-435-440-25y-b0cf6d2f531b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +50 W, cooler, +3.4 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +50 W, cooler, +3.4 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +50 W, cooler, +3.4 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +50 W, cooler, +3.4 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +50 W, cooler, +3.4 pp | | [Hyundai HiE-S430HG(FB)](https://comparepv.com/panel/hyundai-energy-solutions-hie-s430hg-fb) | 430 W | Very close match | | [Hyundai HiE-S440HG](https://comparepv.com/panel/hyundai-energy-solutions-hie-s440hg) | 440 W | +0.2 pp | | [Hyundai HiE-S445HG](https://comparepv.com/panel/hyundai-energy-solutions-hie-s445hg) | 445 W | +10 W, +0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +75 W, cooler, +4.1 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +125 W, cooler, +3.9 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +70 W, cooler, +3.8 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +70 W, cooler, +3.8 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +120 W, cooler, +3.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +65 W, cooler, +3.6 pp | --- Source: https://comparepv.com/panel/hyundai-energy-solutions-hie-s435hg Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
