These modules are based on N-type monocrystalline TOPCon cells, known for their stable performance and low degradation over a long lifespan. The application of half-cut architecture combined with multi-busbar technology (MBB/SMBB) helps minimize resistive losses and improve module performance under partial shading, which translates to higher yields in Polish conditions (chimneys, window frames, trees). In practice, this series offers three key advantages: **superior energy production in low-light conditions**, **high resistance to Potential Induced Degradation (PID)**, and **greater parameter predictability over time**. As a result, the ZXM7-UHLD120 performs exceptionally well in both residential and commercial installations on flat and pitched roofs, where **high power density** and reliable operation across varying temperatures are crucial. Against the competition, this series stands out through the combination of N-TOPCon technology with a module design focused on durability and consistent yield performance. ## Notable figures - Efficiency of 22.2% matches the \*\*TOPCon 450-500W\*\* median - Power density of 222.4 W/m² matches the \*\*TOPCon 450-500W\*\* median - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 450-500W\*\* median - At 26.5 kg, this panel is 2.5 kg heavier than the \*\*TOPCon 450-500W\*\* median (24.0 kg) - more demanding for installation crews - #5722 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### What is the maximum power output of the ZNShine ZXM7-UHLD120 panel? The ZXM7-UHLD120 series reaches up to 485 Wp of maximum power. This is achieved through N-type monocrystalline TOPCon cells combined with a half-cut architecture and multi-busbar metallization (MBB/SMBB), which reduce resistive losses and deliver high power density from a limited roof area without increasing module dimensions. ### What warranty comes with the ZNShine ZXM7-UHLD120 series? The manufacturer provides a 12-year product warranty along with a 30-year power performance warranty. This means the module maintains a guaranteed output level for three decades, while any material or manufacturing defects within the first 12 years are covered by the manufacturer. This is a standard offering from tier-1 manufacturers focused on N-TOPCon cell durability. ### Are the ZXM7-UHLD120 panels bifacial? No, the ZXM7-UHLD120 series consists of monofacial modules, optimized for maximum yield from the front side only. This makes them well suited for typical pitched and flat roof installations, where rear-side mounting wouldn't generate the meaningful extra energy gain that bifacial modules provide in open-ground setups. ### Do ZNShine ZXM7-UHLD120 panels perform well under partial shading, such as from a chimney or antenna? Yes, the half-cut architecture combined with multi-busbar metallization (MBB/SMBB) limits power losses under partial shading, common on Polish roofs due to chimneys, dormers, or antennas. Splitting each cell in half reduces current losses in the shaded section, so the rest of the panel keeps generating power instead of the whole module losing output at once. ### How does the N-TOPCon technology in the ZXM7-UHLD120 differ from standard PERC panels? N-type TOPCon cells offer lower annual degradation and better long-term parameter stability compared to conventional P-type PERC cells. An additional passivation layer reduces electron recombination, resulting in higher efficiency and a smaller power drop over years of operation, giving more predictable energy yields throughout the 30-year power warranty period. ### Are the ZXM7-UHLD120 panels PID-resistant and suitable for large commercial installations? Yes, the series features high resistance to potential-induced degradation (PID), which matters for longer module strings typical of commercial installations. Combined with high power density and stable N-TOPCon cell performance, these modules work well on both flat commercial rooftops and larger residential installations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/zxm7-uhld120-470-485w-e-n-668b58dfac0a.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +30 W, cooler, +2.8 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +2.6 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +2.5 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +2.3 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +2.3 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, lighter, +2.3 pp | | [ZNShine ZXM7-SHLDD120-440](https://comparepv.com/panel/znshine-zxm7-shldd120-440) | 440 W | -40 W, hotter, -1.8 pp | | [ZNShine ZXM7-SHLDD120-445](https://comparepv.com/panel/znshine-zxm7-shldd120-445) | 445 W | -35 W, hotter, -1.6 pp | | [ZNShine ZXM7-SHLDD120-450](https://comparepv.com/panel/znshine-zxm7-shldd120-450) | 450 W | -30 W, hotter, -1.4 pp | | [ZNShine ZXM7-SHLDD120-455](https://comparepv.com/panel/znshine-zxm7-shldd120-455) | 455 W | -25 W, hotter, -1.2 pp | | [ZNShine ZXM7-SHLDD120-460](https://comparepv.com/panel/znshine-zxm7-shldd120-460) | 460 W | -20 W, hotter, -0.9 pp | | [ZNShine ZXM7-SHLDD120-465](https://comparepv.com/panel/znshine-zxm7-shldd120-465) | 465 W | -15 W, hotter, -0.7 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +80 W, cooler, +2.6 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +75 W, cooler, +2.4 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +70 W, lighter, +2.2 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +60 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/znshine-zxm7-uhld120-480-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.
