The application of **N-type cells** and refined connection architecture enables stable operation even under less-than-ideal conditions - such as light cloud cover, cooler mornings, or less favorable exposure. This is a real advantage in Polish installations, where year-round production matters, not just under full sun. A key feature of this series is **double glass**, which increases resistance to environmental factors and limits the risk of micro-cracks, contributing to the installation's longevity. The modules also offer **high resistance to LID and LeTID degradation**, ensuring predictable parameters for years to come. An additional benefit is **beneficial performance at higher temperatures**, helping to mitigate power losses during summer. This is a good choice for single-family homes, commercial buildings, and rooftop installations, where reliability, aesthetics, and long-term energy yield are important. ## Notable figures - At 21.8% efficiency, this panel is on par with typical \*\*N-type 400-450W\*\* modules - 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 - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### What warranty comes with the Runergy HY-DH108N8B 425-445W solar panels? The HY-DH108N8B series comes with a 25-year product warranty covering materials and workmanship, plus a 30-year linear power warranty. Annual degradation after the first year is below 0.4%, meaning the module retains at least 87.4% of its rated output after 30 years. This is one of the longer power warranty standards currently available on the market. ### Is the Runergy HY-DH108N8B a bifacial panel, and what does that mean in practice? Yes, the HY-DH108N8B is a bifacial module, meaning both sides generate electricity. Bifaciality is rated at 80% ±5%, so the rear side can produce up to 80% of the front-side output under suitable conditions. On reflective surfaces - white gravel, concrete, or snow - or in tilted ground-mount systems, annual energy yield can increase by several to over ten percent compared to a monofacial module. ### Are the Runergy HY-DH108N8B panels suitable for a standard pitched residential rooftop? Yes. The modules measure 1722 × 1134 × 30 mm and weigh approximately 24.2 kg, which fits standard rooftop installation parameters. The dual-glass construction improves resistance to mechanical loads, while the low temperature coefficient helps maintain output during summer. The series performs well on south, south-east, or south-west facing rooftops. ### How does N-type cell technology in the HY-DH108N8B differ from standard PERC panels? N-type cells used in the HY-DH108N8B are significantly less susceptible to LID and LeTID degradation compared to p-type PERC cells. This results in smaller power losses in the first years of operation and a more predictable long-term yield. N-type cells also perform better in low-irradiance conditions and at lower temperatures, which provides a real advantage in climates with variable weather. ### How does the HY-DH108N8B perform during hot summer days? N-type modules, including the HY-DH108N8B, have a more favorable temperature coefficient than PERC, which means less power loss on hot days. The dual-glass construction also helps reduce heat buildup. In practice, these panels lose less output during summer heat waves, resulting in higher annual energy yield compared to older-generation modules. ### Is Runergy a reliable manufacturer, and can I trust the HY-DH108N8B for a long-term installation? Runergy holds Bloomberg NEF Tier 1 status, meeting rigorous financial and manufacturing criteria assessed by independent analysts. The company operates its own ingot, wafer, and cell production lines. The HY-DH108N8B carries the certifications required for the European market. For installers and investors, Tier 1 status also simplifies access to financing and insurance for the system. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HY-DH108N8B-Global-Ver25Q3425-445W-404fe10eb6a9.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 | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 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 | --- Source: https://comparepv.com/panel/runergy-hy-dh108n8b-425 Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
