The use of N-type wafers in TOPCon technology translates to more stable performance over time and reduced susceptibility to typical efficiency losses common in older solutions. It stands out from the competition with its **double-glass (glass-glass) construction**, which enhances resistance to moisture, temperature fluctuations, and mechanical stress-an important feature for Poland's climate. The modules utilize **half-cell technology** and **multi-string connection architecture**, improving performance under partial shading and minimizing the risk of hotspots. Thanks to **bifacial capability**, the series effectively utilizes reflected light from the ground, boosting yield especially on ground-mounted installations and flat roofs. This is an excellent choice for installers and investors seeking power density, durability, and predictable yield-ranging from modern homes to commercial projects. ## Notable figures - At 22.5% efficiency, this panel is on par with typical \*\*TOPCon 600-650W\*\* modules - Power density of 225.4 W/m² matches the \*\*TOPCon 600-650W\*\* median - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 600-650W\*\* median - At 30.0 kg, this panel is 2.7 kg lighter than \*\*TOPCon 600-650W\*\* median (32.7 kg) - easier handling during installation - In the top 28% for efficiency among all TOPCon panels ## Questions ### What is the maximum power output of ZNShine ZXM7-UH156 solar panels? Modules in the ZXM7-UH156 series reach up to 630 Wp, placing them among high-output industrial-grade panels. This high per-module power reduces the number of panels needed to reach a given system capacity, lowering mounting structure costs and speeding up installation, especially for larger rooftop and ground-mount projects. ### How does the TOPCon technology in ZXM7-UH156 differ from standard PERC cells? N-type TOPCon cells feature an additional passivation layer that reduces electron recombination losses compared to older P-type PERC cells. In practice, this results in higher efficiency, lower first-year degradation, and more stable energy output over the panel's lifetime, even under elevated module temperatures. ### What warranty comes with ZNShine ZXM7-UH156 panels? The manufacturer offers a 12-year product warranty covering material and workmanship defects, plus a 25-year linear power output warranty. This means that even after a quarter century of operation, the panel is guaranteed to still deliver a specified percentage of its initial rated power, giving investors predictable long-term returns. ### Is the glass-glass construction of ZXM7-UH156 suitable for the Polish climate? Yes, the dual-glass glass-glass build improves module sealing and resistance to moisture, freeze-thaw cycles, and snow loads, which matters given Poland's variable weather conditions. This construction also handles wide seasonal temperature swings between summer and winter better than standard backsheet panels. ### Are ZXM7-UH156 panels bifacial, and does that matter for sloped roof installations? No, the ZXM7-UH156 series is not bifacial - the modules generate power on one side only, which is the standard and proven approach for sloped roofs where panels sit close to the roof surface with no access to reflected light from below. For such installations, bifaciality offers no added benefit, so a monofacial design is fully sufficient. ### Who manufactures the ZXM7-UH156 panels, and is it a reliable supplier? The panels are made by ZNShine Solar, a Chinese PV module manufacturer with Tier 1 status, meaning it appears on the global list of the most financially stable and bankable panel producers, as tracked in reports such as BloombergNEF's. Tier 1 status increases confidence that the manufacturer will remain in business throughout the panel's long-term warranty period. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ZXM7-UH156-182-2465-1134-35-30NH-600-630W-350mm-20230120-E-a5f645d8051a.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, +2.7 pp, +5 yr warranty | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +50 W, +2.7 pp, +5 yr warranty | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +45 W, +2.5 pp, +5 yr warranty | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, +2.5 pp, +5 yr warranty | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +40 W, +2.3 pp, +5 yr warranty | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +40 W, +2.3 pp, +5 yr warranty | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, +2.3 pp, +5 yr warranty | | [ZNShine ZXM7-UH156-600](https://comparepv.com/panel/znshine-zxm7-uh156-600) | 600 W | -30 W, -1.1 pp | | [ZNShine ZXM7-UH156-605](https://comparepv.com/panel/znshine-zxm7-uh156-605) | 605 W | -25 W, -0.9 pp | | [ZNShine ZXM7-UH156-610](https://comparepv.com/panel/znshine-zxm7-uh156-610) | 610 W | -20 W, -0.7 pp | | [ZNShine ZXM7-UH156-615](https://comparepv.com/panel/znshine-zxm7-uh156-615) | 615 W | -15 W, -0.5 pp | | [ZNShine ZXM7-UH156-620](https://comparepv.com/panel/znshine-zxm7-uh156-620) | 620 W | -10 W, -0.4 pp | | [ZNShine ZXM7-UH156-625](https://comparepv.com/panel/znshine-zxm7-uh156-625) | 625 W | Very close match | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +70 W, +2.5 pp, +5 yr warranty | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +65 W, +2.4 pp, +5 yr warranty | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +40 W, +2.3 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/znshine-zxm7-uh156-630 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.
