The use of **N-type TOPCon cells** minimizes losses associated with degradation and helps maintain stable energy production over the long term, which is crucial for investments seeking predictable returns. Modules utilize **half-cut technology** and **multi-string SMBB/16BB connections**, enabling them to better handle partial shading, lower internal resistances, and hot-spot risks. In practice, this series addresses typical challenges encountered in Poland: variable weather, reduced insolation during winter, and power decreases at higher temperatures. The **bifacial double glass** construction allows for additional use of reflected light, which is particularly beneficial on ground installations, flat roofs, and carport structures. This is an excellent choice for commercial and industrial installations as well as solar farms, where longevity, environmental resilience, and a lower energy cost-of-ownership throughout the entire lifecycle are key factors. ## Notable figures - At 21.5% efficiency, this panel is 1.0pp below the \*\*TOPCon 550-600W\*\* median of 22.4% - Power density of 214.8 W/m² is 9.7 W/m² below \*\*TOPCon 550-600W\*\* median (224.4 W/m²) - needs more roof space - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - Weight of 28.0 kg (3.2 kg below \*\*TOPCon 550-600W\*\* median of 31.2 kg) allows easier transport and roof mounting - In the top 58% for efficiency among all TOPCon panels ## Questions ### What is the maximum power output of ZNShine ZXM7-UH144 panels? The highest-power variants in the ZXM7-UH144 series reach up to 580 Wp. This high output results from N-type TOPCon cells, half-cut cell technology, and multi-busbar SMBB/16BB interconnections, which reduce current losses and improve module efficiency per unit area compared to older cell designs. ### What warranty comes with ZNShine ZXM7-UH144 panels? The manufacturer offers a 12-year product warranty and a 25-year power output warranty. This covers both material and workmanship defects, as well as the module's ability to maintain its rated power output over a quarter century, which is important when planning ROI for commercial-scale installations. ### How do N-type TOPCon cells differ from standard PERC cells? The N-type TOPCon cells used in the ZXM7-UH144 series show lower annual degradation and better performance at high temperatures compared to older P-type PERC cells. As a result, the panel retains higher power output for longer, with a slower decline in energy production over the years, translating into higher lifetime energy yield. ### Are ZNShine ZXM7-UH144 panels suitable for solar farms and commercial installations? Yes, this series is designed for commercial, industrial, and utility-scale PV farm installations, where durability and low lifetime energy cost matter most. High module power output (up to 580 Wp) reduces the number of panels needed to reach a target system capacity, lowering costs for mounting structures, cabling, and installation labor. ### How well do ZXM7-UH144 panels handle partial shading? Half-cut cell technology combined with multi-busbar SMBB/16BB interconnections limits the impact of partial shading on overall module performance. Splitting cells into halves reduces internal resistance and hot-spot risk, which matters for roofs with chimneys, dormers, or nearby structures casting shadows. ### Is ZNShine a reliable and established solar panel manufacturer? ZNShine is a China-based manufacturer holding Tier 1 status, meaning the company is recognized as financially stable with a proven track record of large-scale production and supply to major commercial and utility-scale PV projects worldwide. Tier 1 status also makes it easier to secure bank financing for larger installations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ZXM7-UH144-182-2279-1134-35-30NH-555-580W-350mm-20230120-E-052a5e4d046d.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +3.5 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +3.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | -50 W, cooler, +3.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.1 pp, +5 yr warranty | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Lighter, +2.9 pp, +5 yr warranty | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Lighter, +2.9 pp, +5 yr warranty | | [ZNShine ZXM7-SHW144-520](https://comparepv.com/panel/znshine-zxm7-shw144-520) | 520 W | Hotter, lighter, -1.2 pp | | [ZNShine ZXM7-SHW144-525](https://comparepv.com/panel/znshine-zxm7-shw144-525) | 525 W | Hotter, lighter, -1.0 pp | | [ZNShine ZXM7-SHW144-530](https://comparepv.com/panel/znshine-zxm7-shw144-530) | 530 W | Hotter, lighter, -0.8 pp | | [ZNShine ZXM7-SHLD144-530W](https://comparepv.com/panel/znshine-zxm7-shld144-530w) | 530 W | Hotter, -1.0 pp, +5 yr warranty | | [ZNShine ZXM7-SHW144-535](https://comparepv.com/panel/znshine-zxm7-shw144-535) | 535 W | Hotter, lighter, -0.6 pp | | [ZNShine ZXM7-SHLD144-535W](https://comparepv.com/panel/znshine-zxm7-shld144-535w) | 535 W | Hotter, -0.8 pp, +5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +95 W, +3.7 pp, +5 yr warranty | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +90 W, +3.5 pp, +5 yr warranty | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +85 W, +3.3 pp, +5 yr warranty | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +80 W, +3.1 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/znshine-zxm7-uh144-555 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
