The **bifacial and dual-glass design** helps capture additional yield from reflected light off the ground while simultaneously improving resistance to moisture, UV exposure, and accelerated aging - particularly important for installations facing harsh microclimates. A key feature of the HY-DH144P8 is the **high-density cell connection**, which minimizes losses and ensures consistent module performance even under partial shading. In practice, this means fewer "bottlenecks" in the string and better predictability of energy yields. The series also offers **robust mechanical strength**, appreciated by investors planning installations on industrial halls, flat roofs, and PV farms. This is an excellent choice for installers and companies seeking to combine the durability of glass-glass construction with the real benefits of bifacial technology - without compromising on reliability and service. ## Notable figures - Efficiency of 20.7% matches the \*\*PERC 500-550W\*\* median - At 207.1 W/m² power density, roof space requirements are typical for \*\*PERC 500-550W\*\* panels - Temperature coefficient of -0.35%/°C matches the \*\*PERC 500-550W\*\* median - At 32.0 kg, this panel is 3.6 kg heavier than the \*\*PERC 500-550W\*\* median (28.4 kg) - more demanding for installation crews - Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof ## Questions ### What warranty comes with the Runergy HY-DH144P8 solar panels? The HY-DH144P8 series includes a 12-year product warranty covering manufacturing defects and a 30-year linear power warranty. Guaranteed degradation is no more than 2% in year one and 0.45% per year thereafter, leaving at least 84.8% of rated power after 30 years. As a Tier 1 manufacturer, Runergy provides reliable warranty support and bankability for project financing. ### What is the maximum power output of the Runergy HY-DH144P8 and what is inside the module? The top variant in the series is rated at 555 Wp under STC. The module uses 144 mono PERC half-cut cells (6×24 layout) with a 182 mm cell format. The bifacial dual-glass construction delivers a bifaciality factor of approximately 70%, meaning the rear side can generate around 70% of the front-side yield, noticeably boosting annual energy output when ground albedo is favorable. ### Are the Runergy HY-DH144P8 panels suitable for utility-scale solar farms or large flat roofs? Yes, this series is designed primarily for commercial and utility applications. The dual-glass construction resists moisture ingress and UV degradation typical of ground-mount environments. Certified for snow loads up to 5400 Pa and wind loads up to 2400 Pa, the module handles standard mounting conditions in Central Europe. At 2278×1134 mm and 32.7 kg, it is compatible with most fixed-tilt and tracker racking systems. ### What does bifacial technology mean in the HY-DH144P8 and when does it actually pay off? Bifacial modules capture light from both sides — direct irradiance on the front and reflected irradiance on the rear. The HY-DH144P8 has a bifaciality factor of ~70% (±10%). The biggest gains come from high-albedo surfaces: concrete, gravel, white roofing membrane, or snow. On dark, non-reflective surfaces the rear-side gain is negligible. On ground-mount systems with adequate clearance, additional yield of 5–15% is realistic. ### How do the Runergy HY-DH144P8 panels perform in winter and under partial shading? The temperature coefficient of Pmax is -0.35%/°C, so the modules actually produce more efficiently on cold, sunny winter days than in summer heat. The operating range spans -40°C to +85°C. The half-cut cell topology splits each module into two independent electrical strings, reducing mismatch losses under partial shading from chimneys, antennas, or edge snow accumulation compared to standard full-cell modules. ### Is the Runergy HY-DH144P8 series still available and actively supported? Yes, the HY-DH144P8 series is currently in active production and has not been discontinued. Runergy (formerly Hyperion Solar) is a Tier 1 manufacturer with its own factory in China, ensuring supply continuity and up-to-date technical documentation. Before purchasing, confirm the specific datasheet revision with your distributor, as manufacturers occasionally update electrical parameters within the same series name. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HY-DH144P8_535-555W_B30_-Global_-Ver25Q3-fcb4cc329527.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +4.3 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +4.1 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +4.1 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +4.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +3.8 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +3.8 pp | | [Runergy HY-DH144P8-540](https://comparepv.com/panel/runergy-hy-dh144p8-540) | 540 W | Very close match | | [Runergy HY-WH144P8-545](https://comparepv.com/panel/runergy-hy-wh144p8-545) | 545 W | Lighter, +0.4 pp, -5 yr warranty | | [Runergy HY-WH144P8-550](https://comparepv.com/panel/runergy-hy-wh144p8-550) | 550 W | Lighter, +0.6 pp, -5 yr warranty | | [Runergy HY-WH144P8-555](https://comparepv.com/panel/runergy-hy-wh144p8-555) | 555 W | Lighter, +0.8 pp, -5 yr warranty | | [Runergy HY-WH144P8-560](https://comparepv.com/panel/runergy-hy-wh144p8-560) | 560 W | Lighter, +1.0 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +115 W, cooler, +4.5 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +110 W, cooler, +4.3 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +105 W, cooler, +4.1 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +100 W, cooler, +3.9 pp | --- Source: https://comparepv.com/panel/runergy-hy-dh144p8-535 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.
