The ZNShine ZXM7-UHLD144 series was designed for high energy production in real-world operating conditions, including when the weather is unfavorable. The use of N-type TOPCon cells supports more stable operation and sustained performance over time, enhancing the profitability of the installation. These modules utilize a half-cell configuration, which minimizes heating losses and maintains high efficiency under higher current loads.

Another key feature of this series is the SMBB/16BB architecture, which improves current collection from the cells and increases resistance to micro-cracks, particularly in demanding installation scenarios. The double glass construction combined with bifacial technology enables more effective use of reflected light from the ground, increasing yield without expanding the installation surface.

This is an excellent choice for utility-scale PV farms, commercial and industrial (C&I) installations, and projects in challenging environments (e.g., industrial areas, coastal regions), where durability, predictable yield, and reduced degradation risk are crucial.

Common questions

6 answered
What is the maximum power output of the ZNShine ZXM7-UHLD144 series?
Modules in the ZXM7-UHLD144 series reach up to 580 Wp. This is achieved through N-type TOPCon cells in a half-cut layout combined with SMBB/16BB architecture, which together increase conversion efficiency and reduce current losses under heavy loads, resulting in higher yield per module.
What warranty comes with ZNShine ZXM7-UHLD144 panels?
The manufacturer offers a 12-year product warranty and a 30-year linear power output warranty. This means that even after three decades of operation, the panel is expected to retain a guaranteed percentage of its original power output, which is important when calculating the long-term profitability of a PV installation.
What is bifacial technology and do ZXM7-UHLD144 panels use it?
Bifacial technology allows a panel to generate energy from both its front and rear sides, capturing light reflected off the roof, ground, or surrounding surfaces. The ZXM7-UHLD144 series combines double glass construction with bifacial cells, boosting total energy yield without expanding the installation footprint, especially on bright or reflective surfaces.
Are ZNShine ZXM7-UHLD144 panels suitable for solar farms and harsh environmental conditions?
Yes, this series is recommended for PV farms, C&I installations, and demanding locations such as industrial sites or coastal areas. The double glass construction improves resistance to moisture and corrosion, while the SMBB/16BB architecture increases resistance to microcracks, reducing the risk of degradation under variable operating conditions.
How does SMBB/16BB architecture differ from standard panels, and what is its practical benefit?
SMBB/16BB (Super Multi Busbar, 16 busbars) architecture improves current collection across the cell surface compared to older designs with fewer busbars. This reduces resistive losses and increases resistance to microcracks, which matters especially during transport, installation, and operation in demanding field conditions.
Is ZNShine a Tier 1 manufacturer, and what does that mean for buyers?
Yes, ZNShine is classified as a Tier 1 manufacturer according to Bloomberg NEF, reflecting strong financial stability, large-scale production, and years of experience in the PV market. For buyers, this increases confidence that product and power warranties will be honored even decades later, since the manufacturer maintains business continuity.
