The parallel cell architecture delivers measurably better shade tolerance compared to standard series-connected PERC modules. - **Temperature coefficient -0.34%/°C** - The HiE-SxxxHG datasheet confirms a Pmax temperature coefficient of -0.34%/°C, which outperforms the typical PERC median of -0.37% to -0.45%/°C. This translates into higher energy yield during summer peak hours and in warm climates. - **Full Black aesthetics, no visible busbars** - The shingled architecture eliminates visible busbars on the cell surface, producing a uniform, deep-black panel face. This is a direct aesthetic advantage over conventional Full Black modules that retain visible contact fingers. - **Tier-1 bankable manufacturer (Hyundai)** - Hyundai Energy Solutions appears on BNEF bankable manufacturer lists, enabling project financing acceptance by lenders. The financial backing of the global Hyundai conglomerate provides meaningful security behind the 25-year product and service warranty. - **Dual 25/25-year warranty** - The manufacturer provides a 25-year product and workmanship warranty alongside a 25-year linear power warranty guaranteeing ≥84.8% of rated power after 25 years at 0.55% annual degradation. At the time of the series launch (2019-2022), this matched the longest warranties available in the residential PV segment. ## Cons - **Discontinued series (EOL 2023)** - The HG Series ended production in 2023 (launched 2019). New modules are only available from distributor stock, making it impossible to source matching panels for future system expansion. Long-term service part availability is also increasingly at risk. Investors seeking multi-decade support should consider the manufacturer's currently active series. - **P-type PERC - higher degradation vs. N-type** - P-type PERC cells exhibit ~2% first-year LID and ~0.55%/year ongoing degradation (per datasheet), while modern N-type TOPCon modules deliver ~1% LID and ~0.40%/year, guaranteeing 87-90% power retention after 25 years. Over the full warranty period, the cumulative energy yield of HG modules is statistically 3-5% lower than TOPCon alternatives available on the market since 2023. - **Peak efficiency 21.4% - below peer comparables** - The highest-efficiency HG variant reaches 21.4%, matching the SunEvo SE6-46SC (EVOX) at 445 Wp, but trailing the Solitek SOLRIF D Satin (22.06%) by 0.66 pp and the Q-Cells Q.TRON BLACK (22.3%) by 0.9 pp at the same peak power of 445 Wp. On roof areas with limited space, this efficiency gap translates into meaningfully lower energy harvest per square meter. ## About this series Hyundai HG series photovoltaic panels base their design on innovative **shingled technology**, which completely eliminates traditional ribbon connections between cells. This approach allows for denser silicon packing, which translates into higher efficiency and an excellent appearance of the installation. A key benefit for the investor is exceptional **shade resistance** - thanks to the parallel connection of cells, these modules handle power drops much better than standard market solutions. The HG series effectively solves the problem of limited roof space, delivering the maximum amount of energy per square meter while maintaining **high Full Black aesthetics**. The use of conductive adhesive instead of classic soldering drastically reduces thermal stress, which minimizes the risk of micro-cracks and ensures the longevity of the entire system. These products are an ideal choice for single-family homeowners and companies looking for **maximum investment security** guaranteed by a powerful technological conglomerate. They are distinguished from the competition by a unique internal architecture that combines high efficiency with unprecedented resistance to extreme weather conditions, such as strong winds or heavy snow loads.

The Hyundai HG Series has been discontinued and is no longer offered as a new product through official distribution channels. If you are interested in Hyundai Energy Solutions' Shingled technology, it is worth checking local distributor stock for remaining inventory or exploring newer series from the same manufacturer that use a comparable cell architecture. ### What is Shingled cell technology in the Hyundai HG panels and what are the real-world benefits? Shingled technology involves overlapping thin PERC cell strips bonded with electrically conductive adhesive instead of conventional busbars and ribbons. This eliminates internal shading on the active cell surface, increases silicon packing density, and reduces thermomechanical stress. In practice it delivers a module efficiency of up to 21.4% and significantly better partial shading performance compared to standard mono PERC modules. ### How well do Hyundai HG panels handle shading from a chimney or nearby trees? The parallel cell interconnection inherent in the Shingled architecture means that a shaded strip loses output without cutting off the entire string - unlike conventional ribbon-connected cells. For rooftops with chimneys, dormers, or overhanging trees, this translates to higher annual energy yield without the need for individual power optimizers, making the HG Series a practical choice for complex roof layouts. ### What is the peak power output and what are the dimensions of the Hyundai HG 445W panel? The top model in the HG Series is rated at 445 Wp with a module efficiency of 21.4%. Panel dimensions are 1,899 × 1,096 × 30 mm and the weight is approximately 21.8 kg. The maximum system voltage is 1,500 V DC, ensuring compatibility with all mainstream string inverters. This makes it one of the more compact formats in the 440-450 W power class. ### What warranty does Hyundai offer on HG panels and how much power will they retain after 25 years? Hyundai Energy Solutions provides a 25-year product warranty covering material and workmanship defects, as well as a 25-year linear power output warranty. After 25 years of operation the panel is guaranteed to retain at least 84.8% of its rated output. As a Bloomberg NEF Tier 1 manufacturer headquartered in South Korea, Hyundai offers investors strong assurance that the warranty will be honored throughout the module's operational lifetime. ### Are Hyundai HG panels suitable for installation in cool or overcast climates? Yes. The power temperature coefficient of -0.34%/°C is favorable for temperate climates - panels perform more efficiently in cold conditions than in summer heat. The underlying PERC cell technology also improves energy harvest under diffuse irradiance, common during autumn and winter. The module frame is certified for heavy snow load and high wind pressure, making it a reliable choice for northern European rooftop installations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Datasheet-Hyundai-Mono-Shingled-Black-Frame-HiE-S-HG-435-445-9981448b1181.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +50 W, cooler, +3.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, +3.1 pp, +5 yr warranty | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | Cooler, +3.1 pp, +5 yr warranty | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | Cooler, +2.9 pp, +5 yr warranty | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | Cooler, +2.9 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-495M](https://comparepv.com/panel/longi-lr7-54hjd-495m) | 495 W | +50 W, cooler, +2.9 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | Cooler, +2.9 pp, +5 yr warranty | | [Hyundai HiE-S430HG(FB)](https://comparepv.com/panel/hyundai-energy-solutions-hie-s430hg-fb) | 430 W | -15 W, -0.7 pp | | [Hyundai HiE-S435HG](https://comparepv.com/panel/hyundai-energy-solutions-hie-s435hg) | 435 W | -10 W, -0.5 pp | | [Hyundai HiE-S440HG](https://comparepv.com/panel/hyundai-energy-solutions-hie-s440hg) | 440 W | -0.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +65 W, cooler, +3.6 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +115 W, cooler, +3.4 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +60 W, cooler, +3.3 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +60 W, cooler, +3.3 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +110 W, cooler, +3.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +55 W, cooler, +3.1 pp | --- Source: https://comparepv.com/panel/hyundai-hie-s445hg 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.
