The use of **N-type TOPCon** cells helps minimize performance degradation over time and enhances efficiency in challenging conditions, such as high temperatures. The **bifacial** construction allows for the utilization of reflected light from the ground, translating to higher energy production in ground-mounted installations, on flat rooftops, and anywhere where proper reflectivity can be ensured. The robust **glass-glass** architecture increases resistance to moisture, corrosion, and microcracks, while the **half-cut** cells, combined with multi-string connection technology, improve tolerance to partial shading and reduce internal losses. This is an excellent choice for utility-scale PV farms and the C&I segment, where long-term yield and reliability are priorities, not just catalog parameters. ## Notable figures - Efficiency of 21.3% matches the \*\*PERC 550-600W\*\* median - At 212.8 W/m² power density, roof space requirements are typical for \*\*PERC 550-600W\*\* panels - Temperature coefficient of -0.35%/°C matches the \*\*PERC 550-600W\*\* median - At 28.0 kg, this panel is 2.8 kg lighter than \*\*PERC 550-600W\*\* median (30.8 kg) - easier handling during installation - #8795 for efficiency, #10419 for temperature performance out of 14005 panels ## Questions ### What is the maximum power output of ZNShine ZXM7-EH144 panels? The ZXM7-EH144 series offers modules rated up to 560 Wp, placing it among high-output monocrystalline panels based on PERC cells. This power class reduces the number of panels needed to reach a target system capacity, lowering costs for mounting structures, cabling, and installation time, particularly in C&I projects and utility-scale PV farms. ### Are ZXM7-EH144 panels bifacial? No, the ZXM7-EH144 series consists of monofacial modules built with standard PERC technology. This means the panels generate energy only from irradiance hitting the front surface. This design works well in typical rooftop installations, where the rear side wouldn't have access to reflected light anyway. ### What warranty comes with ZNShine ZXM7-EH144 panels? The manufacturer provides a 12-year product warranty and a 25-year power output warranty. As a Tier 1 manufacturer, ZNShine backs its warranties through a partnership with reinsurer Munich Re, giving investors confidence that warranty obligations will be honored over the long term. ### How does the PERC technology in the ZXM7-EH144 differ from newer TOPCon cells? The PERC cells used in the ZXM7-EH144 series are a mature, well-proven technology offering a solid price-to-performance ratio and stable operation under typical conditions. Compared to newer N-type TOPCon cells, PERC has a slightly higher annual degradation rate and lower heat tolerance, but remains a cost-effective choice for large-volume procurement. ### Is ZNShine a reliable solar panel manufacturer? Yes, ZNShine PV-Tech is a China-based manufacturer with a long track record, consistently ranked as a Tier 1 supplier by Bloomberg, confirming its financial stability and production reliability. The company partners with reinsurer Munich Re to back its warranties, adding further security for installers and C&I or utility-scale investors. ### What type of installations are ZXM7-EH144 panels best suited for? With power ratings up to 560 Wp and proven PERC technology, the ZXM7-EH144 series is well suited to large commercial and industrial (C&I) installations as well as utility-scale PV farms, where minimizing cost per Wp and ensuring predictable, stable energy output over the system's lifetime are key priorities. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/zxm7-eh144-182-2279-1134-35-30nh-530-560w-350mm-20240104-e-fafb2371ea27.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +3.7 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +3.5 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, +3.4 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | -50 W, cooler, +3.2 pp | | [ZNShine ZXM7-SHW144-520](https://comparepv.com/panel/znshine-zxm7-shw144-520) | 520 W | -30 W, lighter, -1.0 pp | | [ZNShine ZXM7-SHW144-525](https://comparepv.com/panel/znshine-zxm7-shw144-525) | 525 W | -25 W, lighter, -0.8 pp | | [ZNShine ZXM7-SHW144-530](https://comparepv.com/panel/znshine-zxm7-shw144-530) | 530 W | -20 W, lighter, -0.6 pp | | [ZNShine ZXM7-SHLD144-530W](https://comparepv.com/panel/znshine-zxm7-shld144-530w) | 530 W | Heavier, -0.8 pp, +5 yr warranty | | [ZNShine ZXM7-SHW144-535](https://comparepv.com/panel/znshine-zxm7-shw144-535) | 535 W | -15 W, lighter, -0.4 pp | | [ZNShine ZXM7-SHLD144-535W](https://comparepv.com/panel/znshine-zxm7-shld144-535w) | 535 W | Heavier, -0.6 pp, +5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +85 W, cooler, +3.3 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +80 W, cooler, +3.1 pp | --- Source: https://comparepv.com/panel/znshine-zxm7-eh144-550 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
