These modules stand out with their **high module efficiency**, achieved through advanced cell technology and manufacturing process, as well as **excellent performance under low-light conditions** - where other panels often lose yield (overcast days, mornings, and afternoons). The use of half-cut cells and a multi-string connection structure helps minimize losses and improve system performance under partial shading, which is crucial for roofs with chimneys or window frames. This series is for installers and investors aiming to achieve greater power density on limited surfaces - both on commercial and industrial rooftops, as well as in ground installations. Additional benefits include **enhanced mechanical strength** and **a guarantee of quality and long-term reliability**, facilitating multi-year profitability planning. In practice, the HY-WH144P8 competes not just on price, but on predictable yield and resilience during real-world operation. ## Notable figures - Efficiency of 21.3% matches the \*\*PERC 550-600W\*\* median - At 212.9 W/m² power density, roof space requirements are typical for \*\*PERC 550-600W\*\* panels - At -0.35%/°C, hot weather performance is typical for \*\*PERC 550-600W\*\* panels - Weight of 27.6 kg (3.2 kg below \*\*PERC 550-600W\*\* median of 30.8 kg) allows easier transport and roof mounting - Ranked #8519 out of 14005 panels for efficiency in the database ## Questions ### Is the Runergy HY-WH144P8 series still available for purchase? The Runergy HY-WH144P8 series has been discontinued and is no longer actively manufactured. Availability through distributors may be limited to remaining stock. If you are planning a new installation, it is worth considering current Runergy series based on newer cell technologies that offer comparable or higher efficiency. ### What warranty does the Runergy HY-WH144P8 come with? The HY-WH144P8 modules come with a 12-year product warranty covering material and manufacturing defects. In addition, a 25-year linear power output warranty ensures that after 25 years of operation the panel retains at least 80–82% of its rated power. These are standard warranty conditions for a Tier 1 module in this class. ### What is half-cut PERC technology and does it matter for installations in Poland? Half-cut cells are physically split mono PERC cells that reduce resistive losses and improve performance under partial shading — such as from chimneys or dormers common on Polish rooftops. PERC (Passivated Emitter and Rear Cell) technology enhances light absorption from the rear of the cell, resulting in higher efficiency and better output on overcast days, which make up a significant portion of the year in Poland. ### What is the maximum wattage of the Runergy HY-WH144P8 series? The highest peak power in the HY-WH144P8 series is 560 Wp. The series uses a 144 half-cut mono PERC cell layout, which delivers high power density within standard module dimensions. For projects requiring maximum power on limited roof space — industrial rooftops or ground-mounted systems — this is a significant advantage. ### Do HY-WH144P8 panels perform well in low-light and overcast conditions? Yes, the HY-WH144P8 modules are characterized by good low-light performance, a result of combining mono PERC technology with a half-cut cell layout. On overcast days and in diffuse light conditions, they lose relatively less output compared to older polycrystalline modules. This is especially important in Poland, where a large share of annual energy production comes from cloudy periods, spring, and autumn. ### What types of installations are Runergy HY-WH144P8 modules best suited for? The HY-WH144P8 series is intended primarily for commercial and semi-industrial installations: rooftops of production halls, warehouses, farm buildings, and ground-mounted systems. The high per-module power output (up to 560 Wp) and enhanced mechanical durability make them a strong choice wherever maximum power per square meter and long, trouble-free operation are priorities. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HY-WH144P8_540-560W_B30_-Global_-Ver25Q3-80afebf33dbf.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +3.7 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +3.5 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, +3.4 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | -50 W, cooler, +3.2 pp | | [Runergy HY-DH144P8-535](https://comparepv.com/panel/runergy-hy-dh144p8-535) | 535 W | Heavier, -0.6 pp, +5 yr warranty | | [Runergy HY-DH144P8-540](https://comparepv.com/panel/runergy-hy-dh144p8-540) | 540 W | Heavier, -0.4 pp, +5 yr warranty | | [Runergy HY-WH144P8-545](https://comparepv.com/panel/runergy-hy-wh144p8-545) | 545 W | Very close match | | [Runergy HY-WH144P8-555](https://comparepv.com/panel/runergy-hy-wh144p8-555) | 555 W | Very close match | | [Runergy HY-WH144P8-560](https://comparepv.com/panel/runergy-hy-wh144p8-560) | 560 W | +10 W, +0.4 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +85 W, cooler, +3.3 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +80 W, cooler, +3.1 pp | --- Source: https://comparepv.com/panel/runergy-hy-wh144p8-550 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
