By combining half-cut technology and a multi-string structure, current flows through shorter paths, resulting in more stable module performance and reduced energy losses. A key advantage is the **bifacial structure**, which harnesses reflected light from the ground, effectively boosting energy production without expanding the installation. Additionally, the **glass-glass** construction improves resistance to atmospheric conditions and minimizes the risk of micro-cracks, crucial for projects focused on long-term operation. In practice, **enhanced PID resistance** protects performance in challenging environments. This is the choice for utility-scale PV farms, commercial and ground-mounted installations, where **higher yield** and predictable performance over years is key. ## Notable figures - Efficiency of 20.5% matches the \*\*PERC 500-550W\*\* median - Power density of 205.1 W/m² is 3.9 W/m² below \*\*PERC 500-550W\*\* median (209.0 W/m²) - needs more roof space - At -0.35%/°C, hot weather performance is typical for \*\*PERC 500-550W\*\* panels - Weight of 31.5 kg is 3.1 kg above \*\*PERC 500-550W\*\* median (28.4 kg) - verify structural support - Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof ## Questions ### What is the maximum power output of the ZNShine ZXM7-SHLDD144 panel and which installations does it suit best? The ZXM7-SHLDD144 series reaches up to 555 Wp of maximum power. This high per-panel output makes it well suited for commercial installations, PV farms, and large ground-mount systems, where fewer panels mean less mounting structure, faster installation, and lower cabling costs per watt of installed capacity. ### How does the bifacial design of this series differ from standard monofacial panels? Bifacial ZXM7-SHLDD144 modules generate energy from both sides - the front collects direct sunlight while the rear captures light reflected from the ground, roof, or surrounding surfaces. Depending on surface albedo and mounting height, this can add anywhere from a few to over ten percent extra energy yield without increasing the installation's footprint. ### What warranty comes with ZNShine ZXM7-SHLDD144 panels? The manufacturer provides a 12-year product warranty and a 30-year power performance warranty. This covers both material and workmanship defects as well as gradual power degradation over time, which is an important factor when calculating the long-term return on investment over several decades of operation. ### Does the glass-glass construction in this series mean extra weight and a harder installation? Glass-glass construction is somewhat heavier than standard glass-backsheet panels, but in return it delivers significantly higher mechanical strength, better cell protection against moisture and microcracks, and a longer module lifespan. For installations built for decades of reliable operation, this weight trade-off is well justified, especially in commercial projects and PV farms. ### What does the enhanced PID resistance provide in the ZXM7-SHLDD144 panels? PID (Potential Induced Degradation) resistance protects the module from power losses caused by voltage differences between the cells and the frame or grounding, a common issue in large installations with high system voltage. This feature keeps performance stable even in humid climates and with long strings, which is typical for commercial installations and PV farms. ### What cell technology does the ZXM7-SHLDD144 series use, and how does it differ from TOPCon? The series uses proven PERC cell technology in a half-cut, multi-busbar layout, which shortens current paths and reduces resistive losses as well as the impact of partial shading. Compared to newer TOPCon technology, PERC offers slightly lower base efficiency but is a mature technology with proven durability and lower production cost, resulting in a more competitive module price. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ZXM7-SHLDD144-182-2279-1134-30-32NH-530-555W-350mm-20220823-5c6bb1bf9f3a.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +4.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +4.3 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +4.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +4.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +4.1 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +4.0 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +4.0 pp | | [ZNShine ZXM7-SHW144-520](https://comparepv.com/panel/znshine-zxm7-shw144-520) | 520 W | 18 kg lighter, -0.2 pp, -5 yr warranty | | [ZNShine ZXM7-SHW144-525](https://comparepv.com/panel/znshine-zxm7-shw144-525) | 525 W | 18 kg lighter, -5 yr warranty | | [ZNShine ZXM7-SHW144-530](https://comparepv.com/panel/znshine-zxm7-shw144-530) | 530 W | 18 kg lighter, -5 yr warranty | | [ZNShine ZXM7-SHW144-535](https://comparepv.com/panel/znshine-zxm7-shw144-535) | 535 W | 18 kg lighter, +0.4 pp, -5 yr warranty | | [ZNShine ZXM7-SHLD144-535W](https://comparepv.com/panel/znshine-zxm7-shld144-535w) | 535 W | Very close match | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +120 W, cooler, +4.7 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +115 W, cooler, +4.5 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +110 W, cooler, +4.3 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +105 W, cooler, +4.1 pp | --- Source: https://comparepv.com/panel/znshine-zxm7-shldd144-530 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.
