The ZNShine ZXM7-UHLDD144 series was designed to maximize energy yield in real-world operating conditions - especially where every additional percent of production matters. The modules utilize N-type TOPCon cells, which perform well under weaker irradiance and help maintain stable system operation on cloudy days. The application of bifacial glass-glass construction enables energy harvesting from the rear side as well, translating to higher yields on the ground, trackers, and with a bright background.

A key feature of this series is half-cut and multi-string (SMBB/16BB) technology, which minimizes resistive losses and improves partial shading tolerance - crucial for industrial installations and PV farms where conditions rarely are ideal. The modules are also designed for operation in harsher environments, offering enhanced resistance to environmental factors (e.g., moisture, dust, or salinity). This is a sensible choice for investors seeking reliable production, longevity, and lower energy costs over the long term.

Common questions

6 answered
What is the maximum power output of ZNShine ZXM7-UHLDD144 panels?
The ZXM7-UHLDD144 series reaches a maximum power output of up to 580 Wp. This is a high value for this module format, achieved thanks to N-type TOPCon cells combined with half-cut technology and multi-busbar interconnection (SMBB/16BB), which together reduce resistive losses and improve solar-to-electric conversion efficiency.
How does the TOPCon technology in ZXM7-UHLDD144 differ from standard PERC cells?
The N-type TOPCon cells used in this series show lower degradation over time and better performance under low-light conditions than standard P-type PERC cells. In practice, this means more stable energy production on cloudy days and higher annual yield, resulting in a shorter payback period for the investment.
What warranty comes with ZNShine ZXM7-UHLDD144 panels?
The manufacturer provides a 12-year product warranty and a 30-year linear power output warranty. Such terms are typical for modern TOPCon panels and reflect the manufacturer's confidence in the durability of N-type cells and the glass-glass construction used in this series.
Are bifacial ZXM7-UHLDD144 panels worth it for ground-mounted and tracker systems?
Yes, the bifacial glass-glass construction allows the module to capture additional reflected light through its rear side. This effect is most noticeable in ground-mounted installations, PV farms, and tracker-based systems, especially over bright or sandy ground, where the bifacial gain can add several percent to annual energy production.
Are ZNShine ZXM7-UHLDD144 panels suitable for industrial installations with partial shading?
Yes, the half-cut cell technology combined with multi-busbar interconnection (SMBB/16BB) reduces power losses under partial shading, for example from chimneys, antennas, or neighboring rows on PV farms. By splitting cells into smaller sections, shading on part of the module has a smaller impact on the output of the entire panel string.
Is ZNShine a Tier 1 manufacturer, and where are ZXM7-UHLDD144 panels produced?
ZNShine Solar holds Tier 1 manufacturer status, confirming the company's financial stability and experience in large-scale PV module production. Panels from the ZXM7-UHLDD144 series are manufactured in China, and their enhanced resistance to moisture, dust, and salt mist makes them suitable for installations in demanding climate conditions as well.
