The key advantage is minimizing typical losses associated with older technologies-this design performs better against light and temperature-induced degradation, ensuring more stable energy production over the long term. The **high-density packaging** and reliability-enhancing solutions (including precise cell processing) help reduce the risk of micro-cracking and yield drops over time. In practice, this series addresses the needs of investors with limited mounting space or those seeking to maximize self-consumption-thanks to good performance under weaker sunlight, the installation generates energy for longer throughout the day. This is an excellent choice for homes, businesses, and projects where **high compatibility** with modern inverters and long-term yield predictability are key. ## Notable figures - At 22.5% efficiency, this panel is 0.5pp above typical \*\*TOPCon 400-450W\*\* modules (median: 22.0%) - At 225.3 W/m² power density, this panel generates 5.1 W/m² more per unit area than \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 400-450W\*\* median - At 20.5 kg, this panel is 1.5 kg lighter than \*\*TOPCon 400-450W\*\* median (22.0 kg) - easier handling during installation - In the top 28% for efficiency among all TOPCon panels ## Questions ### What is the maximum power output and efficiency of the ZNShine ZXM7-UH108 panel? The flagship variant of the ZXM7-UH108 series reaches up to 440 Wp with a module efficiency around 22%. This is achieved through N-type TOPCon half-cut cells, which make better use of the available surface than older PERC technology. For roofs with limited space, this means more energy output from the same number of panels. ### What warranty does ZNShine offer on the ZXM7-UH108 series? The manufacturer provides a 15-year product warranty and a 25-year linear power performance warranty. ZNShine holds Tier 1 status, which adds further confidence that the company will remain financially stable and able to honor warranty claims throughout this period. ### How does TOPCon cell technology in the ZXM7-UH108 differ from a standard PERC panel? N-type TOPCon cells feature an additional passivation layer that reduces electron recombination and minimizes light- and temperature-induced degradation (LeTID). In practice, the panel loses less power in its early years and performs better at high roof temperatures compared to a conventional P-type PERC module, resulting in higher annual energy yield. ### Is the ZXM7-UH108 series suitable for sloped roofs with limited surface area? Yes, this is one of the series' main use cases. The high-density half-cut cell layout packs more power into a smaller roof area, and the panel's strong performance under diffuse or weaker light means the system generates energy for longer during the day, even with partial shading or a less-than-ideal orientation. ### Is the ZNShine ZXM7-UH108 panel a bifacial module? No, this specific version of the ZXM7-UH108 series is a monofacial module, optimized for standard rooftop and commercial installations rather than ground-mount or carport applications that rely on reflected light hitting the back side of the panel. ZNShine offers a separate dual-glass product line for customers who need a bifacial variant. ### Which inverters are compatible with the ZXM7-UH108 series panels? Modules in this series are designed for high compatibility with modern string and hybrid inverters on the market, including popular brands that support standard voltage and current parameters for 440 Wp-class modules. Before finalizing an inverter choice, it's worth checking the exact MPPT voltage range against the current datasheet. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/zxm7-uh108-425-440w-e-n-94616fb4e992.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +50 W, +2.0 pp, +5 yr warranty | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +50 W, +2.0 pp, +5 yr warranty | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +45 W, +1.8 pp, +5 yr warranty | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +45 W, +1.8 pp, +5 yr warranty | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +45 W, +1.8 pp, +5 yr warranty | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +45 W, +1.8 pp, +5 yr warranty | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +45 W, +1.8 pp, +5 yr warranty | | [ZNShine ZXM7-SH108-395W](https://comparepv.com/panel/znshine-zxm7-sh108-395w) | 395 W | -45 W, hotter, -2.3 pp | | [ZNShine ZXM7-SH108-400W](https://comparepv.com/panel/znshine-zxm7-sh108-400w) | 400 W | -40 W, hotter, -2.1 pp | | [ZNShine ZXM7-SH108-405W](https://comparepv.com/panel/znshine-zxm7-sh108-405w) | 405 W | -35 W, hotter, -1.8 pp | | [ZNShine ZXM7-SH108-410W](https://comparepv.com/panel/znshine-zxm7-sh108-410w) | 410 W | -30 W, hotter, -1.5 pp | | [ZNShine ZXM7-SH108-415W](https://comparepv.com/panel/znshine-zxm7-sh108-415w) | 415 W | -25 W, hotter, -1.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +70 W, cooler, +2.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +55 W, +2.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +65 W, cooler, +2.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +60 W, cooler, +2.0 pp | --- Source: https://comparepv.com/panel/znshine-zxm7-uh108-440-n Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
