Key features include **monocrystalline N-type cells with TOPCon technology**, which maintain efficiency over time and are more resistant to typical degradation phenomena. Modules utilize **half-cut architecture and multi-busbar (SMBB)** technology, reducing resistive losses and improving performance under partial shading. In practice, this means more stable energy production in Polish conditions-particularly under low sunlight, on cloudy days, and during早晚 (morning and evening)-thanks to **excellent responsiveness to low light conditions**. An additional highlight is the **double-glass construction**, which enhances resistance to moisture, corrosion, and micro-cracking, and also helps mitigate operational risks in demanding locations. This series is for investors who demand reliability in residential, commercial, and industrial installations, as well as projects focused on longevity and long-term yield. ## Notable figures - At 22.5% efficiency, this panel is 0.5pp above typical \*\*TOPCon 400-450W\*\* modules (median: 22.0%) - Power density of 225.3 W/m² packs 5.1 W/m² more into the same footprint vs \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 400-450W\*\* panels - Weight of 24.5 kg is 2.5 kg above \*\*TOPCon 400-450W\*\* median (22.0 kg) - verify structural support - In the top 28% for efficiency among all TOPCon panels ## Questions ### How does the ZNShine ZXM7-UHLD108 series differ from standard PERC modules? The ZXM7-UHLD108 series uses N-type monocrystalline TOPCon cells, which degrade more slowly than older PERC cells and maintain efficiency better over the module's lifetime. Additionally, the half-cut architecture and multi-busbar (SMBB) design reduce resistive losses, resulting in higher energy yield from the same roof or ground area. ### Do ZNShine ZXM7-UHLD108 panels perform well in low-light and cloudy conditions? Yes, thanks to TOPCon technology and the half-cut design, this series delivers very good low-light responsiveness. This means more stable power generation in the morning, evening, and on overcast days, which is important in climates with limited hours of full sun. ### What warranty comes with the ZNShine ZXM7-UHLD108 panels? The manufacturer provides a 15-year product warranty and a 30-year linear power output warranty. This means that after 30 years of operation, the module should still retain the guaranteed percentage of its original rated power, making this series suitable for long-term investments, including ground-mount and commercial installations. ### What are the benefits of the double-glass construction in ZXM7-UHLD108 panels? The double-glass construction replaces the rear backsheet with a second layer of glass, significantly increasing resistance to moisture ingress, junction corrosion, and cell micro-cracks. In practice this reduces failure risk in demanding operating conditions, such as large temperature swings or high humidity, and extends the panel's overall lifespan. ### Are ZNShine ZXM7-UHLD108 panels bifacial, and is it worth it? Yes, the ZXM7-UHLD108 series is built with bifacial technology, meaning it also generates power from the rear side of the module using light reflected off the ground. This is especially beneficial for ground-mount installations on bright surfaces (e.g., gravel, white roofing) and mounting structures with adequate rear clearance, where the additional yield can range from a few to over a dozen percent. ### Who manufactures the ZNShine ZXM7-UHLD108 panels, and is it a reliable supplier? The panels are manufactured by ZNShine Solar, a well-established Chinese photovoltaic manufacturer classified as Tier 1 under the Bloomberg NEF ranking. Tier 1 status indicates financial stability and bankability, making financing easier to obtain and providing greater confidence in honoring warranty claims over the product's long service life. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/zxm7-uhld108-425-440w-e-n-0e3f8058a54c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +50 W, cooler, +2.0 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +50 W, cooler, +2.0 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +45 W, lighter, +1.8 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +45 W, cooler, +1.8 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +45 W, cooler, +1.8 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +45 W, cooler, +1.8 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +45 W, cooler, +1.8 pp | | [ZNShine ZXM7-SH108-395W](https://comparepv.com/panel/znshine-zxm7-sh108-395w) | 395 W | Hotter, -2.3 pp, -5 yr warranty | | [ZNShine ZXM7-SH108-400W](https://comparepv.com/panel/znshine-zxm7-sh108-400w) | 400 W | Hotter, -2.1 pp, -5 yr warranty | | [ZNShine ZXM7-SH108-405W](https://comparepv.com/panel/znshine-zxm7-sh108-405w) | 405 W | Hotter, -1.8 pp, -5 yr warranty | | [ZNShine ZXM7-SH108-410W](https://comparepv.com/panel/znshine-zxm7-sh108-410w) | 410 W | Hotter, -1.5 pp, -5 yr warranty | | [ZNShine ZXM7-SH108-415W](https://comparepv.com/panel/znshine-zxm7-sh108-415w) | 415 W | Hotter, -1.3 pp, -5 yr warranty | | [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, cooler, +2.3 pp | | [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-uhld108-440-n Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
