The transparent version allows light to pass under the module, facilitating solutions like carports, terrace canopies, awnings, or skylights in commercial properties - without the feeling of a heavy, dark canopy. The use of **N-type cells** combined with **bifacial technology** helps better utilize both diffuse and reflected light, translating into more stable energy production under Poland’s typical variable weather conditions. The **double glass** construction increases resistance to moisture, micro-cracks, and loads, which investors seeking reliable performance over years will appreciate. Furthermore, the **low susceptibility to degradation** typical of N-type limits power decay over time, while the **high power output in low-light conditions** supports self-consumption in residential and commercial buildings. This is the choice for projects where competitors often offer either the look or the performance - here, you get both. ## Notable figures - Efficiency of 21.8% matches the \*\*N-type 400-450W\*\* median - Power density of 217.6 W/m² matches the \*\*N-type 400-450W\*\* median - At -0.29%/°C, hot weather performance is typical for \*\*N-type 400-450W\*\* panels - At 24.2 kg (2.2 kg above \*\*N-type 400-450W\*\* median of 22.0 kg), requires checking roof load capacity - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### Are Runergy HY-DH108N8 Transparent panels suitable for carport or pergola installations? Yes, the HY-DH108N8 Transparent series is specifically designed for these applications. The transparent variant allows light to pass through, so the canopy avoids the heavy, opaque look of standard modules — carports, pergolas, and terrace overhangs retain a natural, open feel. The double glass construction (2.0 mm tempered glass front and back) provides rigidity and moisture resistance without requiring a full aluminum perimeter frame. ### What warranty does the Runergy HY-DH108N8 Transparent come with? Runergy provides a 25-year product warranty and a 30-year linear power output warranty. Degradation is specified at less than 1% in year one and less than 0.4% per year thereafter, meaning the module should retain at least 87.4% of its rated output after 30 years — one of the stronger linear power guarantees in this product class. ### What is N-type TOPCon technology and why does it matter for this series? N-type TOPCon cells exhibit significantly lower light-induced degradation (LID) than conventional PERC cells, resulting in more stable power output throughout the panel's service life. The temperature coefficient of Pmax is just -0.29%/°C, which means less power loss on hot summer days when module temperatures can exceed 60°C. Over a multi-decade installation, this technology advantage translates into a measurably higher real-world energy yield. ### Does bifacial functionality work on the transparent version and how does it affect energy yield? Yes, the HY-DH108N8 Transparent retains full bifacial capability — the rear face still captures light reflected from the ground or surrounding surfaces. In carport installations over light-colored surfaces such as concrete or light gravel, or in pergolas with reflective environments, the bifacial gain can add several percentage points to actual energy production, depending on the albedo of the surface below the array. ### How do Runergy HY-DH108N8 Transparent panels perform under typical overcast conditions in Central Europe? The 108 half-cut N-type cell layout handles diffuse irradiance well. Smaller cell segments reduce the impact of partial shading, and the low temperature coefficient (-0.29%/°C) limits power loss on cool, overcast days compared to older PERC technology. In climates like Poland's, where a significant share of annual generation comes from low or diffuse irradiance, this translates into a noticeably better capacity factor over the system's lifetime. ### How much does the Runergy HY-DH108N8 Transparent weigh and what are the structural requirements? The module weighs approximately 24.2 kg with dimensions of 1722 × 1134 × 30 mm. The double glass construction is heavier than backsheet modules, so carport, pergola, or skylight structures must account for the higher dead load. For larger canopy areas, a structural engineer should verify the load-bearing capacity of the steel or aluminum substructure before installation. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HY-DH108N8-Trans-Global-Ver25Q3425-445W-7586f0335584.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | +50 W, +2.2 pp, +10 yr warranty | | [Just Solar JST-EDMH-(445-465)W-TD (465W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-465w-class) | 465 W | +40 W, lighter, +2.0 pp | | [JA Solar JAT54S40-475/LR](https://comparepv.com/panel/ja-solar-jat54s40-475-lr) | 475 W | +50 W, lighter, +2.0 pp | | [Tongwei TWMNH-48HW475](https://comparepv.com/panel/tongwei-solar-twmnh-48hw475) | 475 W | +50 W, +2.0 pp | | [Astronergy CHSM48RN(DG)/F-BH-475](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-f-bh-475) | 475 W | +50 W, +2.0 pp | | [AIKO AIKO-A475-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a475-mce54mw) | 475 W | +50 W, lighter, +2.0 pp | | [AIKO AIKO-A475-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a475-mah54mw) | 475 W | +50 W, cooler, +2.0 pp | | [Runergy HY-DH108N8B-430](https://comparepv.com/panel/runergy-hy-dh108n8b-430) | 430 W | Very close match | | [Runergy HY-DH108N8B-435](https://comparepv.com/panel/runergy-hy-dh108n8b-435) | 435 W | +10 W, +0.5 pp | | [Runergy HY-DH108N8B-440](https://comparepv.com/panel/runergy-hy-dh108n8b-440) | 440 W | +15 W, +0.7 pp | | [Runergy HY-DH108N8B-445](https://comparepv.com/panel/runergy-hy-dh108n8b-445) | 445 W | +20 W, +1.0 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +85 W, cooler, +3.2 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +70 W, lighter, +3.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +80 W, cooler, +2.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +65 W, lighter, +2.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +75 W, cooler, +2.7 pp | --- Source: https://comparepv.com/panel/runergy-hy-dh108n8-425 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
