The use of **half-cut** cells arranged in a multi-busbar layout reduces resistive losses and delivers a more even current distribution, resulting in more stable performance even under partial shading. A key advantage of the series is its **bifacial design** with dual glass construction, which allows the module to capture additional reflected energy from bright surfaces, rooftops, or snow, lowering the effective levelized cost of energy (LCOE) over the system's lifetime. The panel also stands out for its **high mechanical durability** against snow and wind loads, making it suitable both for pitched roofs on single-family homes and for larger commercial and industrial installations. The N-type technology reduces LID/LeTID degradation and improves module behavior under low-light and high-temperature conditions, which matters for investors expecting predictable energy production over decades. The HY-DH108N8B is built for installers and investors looking for efficiency, durability, and lower BoS costs in a single module. ## Notable figures - At 22.3% efficiency, this panel is on par with typical \*\*N-type 400-450W\*\* modules - At 222.8 W/m² power density, this panel generates 4.5 W/m² more per unit area than \*\*N-type 400-450W\*\* median (218.3 W/m²) - Temperature coefficient of -0.29%/°C matches the \*\*N-type 400-450W\*\* median - At 24.2 kg, this panel is 2.2 kg heavier than the \*\*N-type 400-450W\*\* median (22.0 kg) - more demanding for installation crews - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### Is the Runergy HY-DH108N8B panel suitable for a pitched residential roof? Yes, the HY-DH108N8B series works well on both pitched roofs and commercial installations. The half-cut cell design in a multi-busbar configuration improves resistance to partial shading, while high mechanical strength against snow and wind loads means the panel holds up well under typical conditions found on sloped roofs. ### What does the bifacial design of the HY-DH108N8B offer, and is it worth the extra cost? The double-glass bifacial construction allows the module to capture additional light reflected off bright surfaces, roofing, or snow, generating extra energy from the rear side of the panel. In practice, this means higher real-world energy yield over the system's lifetime and a lower LCOE, especially when installed above bright surfaces or in ground-mounted arrays. ### What warranty comes with Runergy HY-DH108N8B panels? The HY-DH108N8B panels come with a 12-year product warranty and a 30-year linear power output warranty. This means the manufacturer guarantees a gradually declining but predictable performance level over three decades, which is important when calculating the long-term profitability of a PV installation. ### How does the N-type TOPCon technology in the HY-DH108N8B differ from standard PERC panels? The N-type TOPCon cells used in this series show lower LID and LeTID degradation compared to conventional P-type PERC cells. As a result, the panel maintains better efficiency under low-light conditions and high temperatures, leading to more stable and predictable energy output throughout the system's operating life. ### What is the maximum power output of the HY-DH108N8B, and what installations is it suited for? Modules in the HY-DH108N8B series reach a maximum power output of up to 450 Wp. This makes the panel a good fit for both residential prosumer installations and larger commercial or industrial projects, where high power density per available roof or ground area is a key factor. ### Is Runergy a reliable manufacturer, and where are HY-DH108N8B modules produced? Runergy is a Tier 1 manufacturer headquartered in China, a classification confirmed by industry rankings of financial stability and production scale. This status gives investors greater confidence in warranty backing and manufacturing quality over the module's long-term operating life. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HY-DH108N8B-Global-Ver25Q4Bifacial_430-450W-136177c6fcc4.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, lighter, +2.0 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +50 W, lighter, +2.0 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +50 W, cooler, +2.0 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +50 W, lighter, +2.0 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +50 W, cooler, +2.0 pp | | [Runergy HY-DH108N8-425](https://comparepv.com/panel/runergy-hy-dh108n8-425) | 425 W | -10 W, -0.5 pp | | [Runergy HY-DH108N8B-430](https://comparepv.com/panel/runergy-hy-dh108n8b-430) | 430 W | -0.3 pp | | [Runergy HY-DH108N8B-440](https://comparepv.com/panel/runergy-hy-dh108n8b-440) | 440 W | Very close match | | [Runergy HY-DH108N8B-445](https://comparepv.com/panel/runergy-hy-dh108n8b-445) | 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, +2.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +60 W, lighter, +2.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +70 W, cooler, +2.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +55 W, lighter, +2.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +65 W, cooler, +2.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +65 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/runergy-hy-dh108n8b-435 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.
