The use of **n-type TOPCon cells** helps minimize losses associated with material aging and maintains high efficiency over a long operational lifespan. The construction based on **half-cut cells** improves performance under partial shading and reduces resistive losses, resulting in more predictable energy production in real rooftop conditions. Another distinguishing feature is the **MultiBus/MultiBus II (MBB/SMBB) technology**, which enhances current harvesting from the cells and improves resistance to micro-cracking. In practice, this solution benefits investors who aim to minimize performance degradation over time and expect good results even under lower irradiance conditions. This series is suitable for residential and commercial installations, especially where compatibility with modern inverters and optimizers, as well as high module quality, is important. Compared to many standard PERC panels, the advantage lies in **superior degradation resistance and better performance in challenging conditions**. ## Notable figures - At 22.5% efficiency, this panel is on par with typical \*\*TOPCon 450-500W\*\* modules - At 224.7 W/m² power density, roof space requirements are typical for \*\*TOPCon 450-500W\*\* panels - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 450-500W\*\* panels - Weight of 23.0 kg is typical for \*\*TOPCon 450-500W\*\* panels - Ranked #4576 out of 14005 panels for efficiency in the database ## Questions ### What is the maximum power output of the ZNShine ZXM7-UH120 panel? Panels from the ZXM7-UH120 series reach a maximum power output of up to 485 Wp. High power combined with relatively compact module dimensions results in better use of available roof space and fewer panels needed to reach the target system capacity. ### What warranty comes with ZNShine ZXM7-UH120 panels? The manufacturer provides a 12-year product warranty and a 25-year linear power output warranty. This means the panel is guaranteed to retain a defined percentage of its nominal power over a quarter century of operation, which is standard for modern n-type TOPCon modules. ### How does TOPCon technology in the ZXM7-UH120 differ from standard PERC panels? The n-type TOPCon cells used in the ZXM7-UH120 series have a lower degradation rate than typical p-type PERC cells and perform better at higher temperatures. In practice, this means a slower decline in efficiency over the years and higher real-world energy yield compared to older PERC designs. ### Do ZXM7-UH120 panels perform well under partial shading? Yes, the half-cut cell design used in the ZXM7-UH120 series limits the impact of partial shading on overall module performance. Splitting cells into smaller segments reduces resistive losses, so shading a fragment of the panel, for example from a chimney or antenna, doesn't drastically cut power output from the whole module. ### What is MBB/SMBB multi-busbar technology and what's its advantage? Multi-busbar (MBB/SMBB) technology increases the number of thin conductive lines collecting current from the cell surface. A shorter current path reduces resistive losses, while more solder connections improve resistance to microcracks that can develop during transport, installation, or operation. ### Are ZNShine ZXM7-UH120 panels compatible with inverters from different manufacturers? Yes, the ZXM7-UH120 series is designed for compatibility with popular inverters and power optimizers used in residential and commercial installations. ZNShine is a Tier 1 manufacturer, which also makes project financing and insurance easier to secure. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ZXM7-UH120-182-1903-1134-30-32NH-460-485W-350mm-20230120-E-6fe33d1885e9.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +2.5 pp, +5 yr warranty | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, +2.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, +2.2 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, +2.0 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, +2.0 pp, +5 yr warranty | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, +2.0 pp, +5 yr warranty | | [ZNShine ZXM7-SHLDD120-440](https://comparepv.com/panel/znshine-zxm7-shldd120-440) | 440 W | Hotter, -2.1 pp, +5 yr warranty | | [ZNShine ZXM7-SHLDD120-445](https://comparepv.com/panel/znshine-zxm7-shldd120-445) | 445 W | Hotter, -1.8 pp, +5 yr warranty | | [ZNShine ZXM7-SHLDD120-450](https://comparepv.com/panel/znshine-zxm7-shldd120-450) | 450 W | Hotter, -1.6 pp, +5 yr warranty | | [ZNShine ZXM7-SHLDD120-455](https://comparepv.com/panel/znshine-zxm7-shldd120-455) | 455 W | Hotter, -1.4 pp, +5 yr warranty | | [ZNShine ZXM7-SHLDD120-460](https://comparepv.com/panel/znshine-zxm7-shldd120-460) | 460 W | Hotter, -1.1 pp, +5 yr warranty | | [ZNShine ZXM7-SHLDD120-465](https://comparepv.com/panel/znshine-zxm7-shldd120-465) | 465 W | Hotter, -0.9 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +75 W, +2.3 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +70 W, +2.1 pp, +5 yr warranty | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +65 W, lighter, +1.9 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +55 W, +1.9 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/znshine-zxm7-uh120-485 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
