The panels are built on **N-Type TOPCon technology** using a 182 mm cell platform, delivering high conversion efficiency and stable performance even under diffuse light and elevated temperatures. The use of **half-cut cells** reduces resistive losses and limits the impact of partial shading on the performance of the whole module string, which matters on unconventional roof layouts. The **bifacial dual-glass design** captures additional energy reflected from the ground - soil, gravel, or a light-colored roof surface - making the series a strong fit for ground-mount and freestanding installations. Runergy places heavy emphasis on durability: the modules offer **strong resistance to LID, LeTID, and PID degradation**, while their mechanical structure withstands heavy snow, wind, and hail loads. The whole series is backed by a **30-year linear power warranty**, making it a solid choice for both commercial-scale installations and demanding prosumer projects focused on a low lifetime cost of energy. ## Notable figures - At 22.8% efficiency, this panel is 0.9pp above typical \*\*N-type 400-450W\*\* modules (median: 21.9%) - Power density of 227.9 W/m² packs 9.6 W/m² more into the same footprint vs \*\*N-type 400-450W\*\* median (218.3 W/m²) - At -0.29%/°C, hot weather performance is typical for \*\*N-type 400-450W\*\* panels - 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 - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### How does the Runergy HY-DH108N8 panel differ from standard PERC modules? The HY-DH108N8 uses N-type TOPCon cells instead of standard PERC, delivering higher conversion efficiency and lower power loss at elevated temperatures and under diffuse light. It also features half-cut cells, which reduce resistive losses and improve resilience to partial shading. This newer-generation technology yields better energy output per square meter of roof. ### Is a bifacial panel like the HY-DH108N8 worth it on a standard pitched roof? Bifacial technology delivers the greatest benefit in ground-mount installations, freestanding structures, or flat roofs with a reflective surface, where the rear side captures reflected light. On a typical pitched roof, where the panel sits close to the surface, the bifacial gain is minimal, but the module still performs well thanks to its TOPCon technology and half-cut cell design. ### What warranty comes with the Runergy HY-DH108N8 panels? The manufacturer offers a 12-year product warranty along with a 30-year linear power warranty. This means the module is expected to maintain high energy performance over three decades, with a predictable, gradual power decline. This level of coverage is standard for modern N-type panels and makes the investment more predictable over the long term. ### What is the maximum power output of the HY-DH108N8 series panels? Modules in this series reach up to 450 Wp of maximum power. This is the result of combining a 182 mm cell platform with N-type TOPCon technology and a half-cut structure, together boosting conversion efficiency while keeping a compact panel footprint, which helps in designing high power-density installations. ### Do Runergy panels perform well on hot days and at high temperatures? Yes, one of the key advantages of N-type TOPCon technology is a low power temperature coefficient, meaning less efficiency loss as the module heats up compared to classic PERC panels. As a result, the HY-DH108N8 maintains more stable energy production on hot, sunny days, which matters especially in summer on roofs with limited ventilation. ### Is Runergy a reliable solar panel manufacturer? Runergy is a Chinese manufacturer holding Tier 1 status, indicating strong financial standing, in-house production capacity, and long-standing global market presence confirmed by industry classifications such as BloombergNEF. Tier 1 status increases confidence in long-term warranty support, since the manufacturer is more financially stable than smaller, unclassified producers. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HY-DH108N8-Global-Ver25Q4Bifacial_430-450W-15a88599b600.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +50 W, lighter, +2.0 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +45 W, lighter, +1.7 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +45 W, cooler, +1.7 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +40 W, lighter, +1.5 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +40 W, lighter, +1.5 pp | | [Longi Solar LR7-54HJD-495M](https://comparepv.com/panel/longi-lr7-54hjd-495m) | 495 W | +50 W, cooler, +1.5 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +40 W, cooler, +1.5 pp | | [Runergy HY-DH108N8-425](https://comparepv.com/panel/runergy-hy-dh108n8-425) | 425 W | -20 W, -1.0 pp | | [Runergy HY-DH108N8B-430](https://comparepv.com/panel/runergy-hy-dh108n8b-430) | 430 W | -15 W, -0.8 pp | | [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 | -0.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +65 W, cooler, +2.2 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +60 W, cooler, +1.9 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +55 W, cooler, +1.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +55 W, cooler, +1.7 pp | --- Source: https://comparepv.com/panel/runergy-hy-dh108n8-445 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.
