The ZNShine ZXM7-SHLDD120 series are bifacial glass-glass modules engineered for reliable energy production under real-world conditions, including diffuse light and transient periods. Their dual-sided operation harnesses reflected light from the ground, providing additional yield where standard monofacial modules often reach their economic breakeven point faster. The applied half-cut and multi-string architecture minimizes resistive losses and enhances module performance under partial shading - crucial for rooftops with obstructions or systems with varied exposure.

Key features include bifacial generation combined with durable glass-glass construction, facilitating operation in high-humidity environments and mechanical stress. Installers should also consider high PID resistance and excellent low-light performance. The ZXM7-SHLDD120 is ideal for residential and commercial rooftops, carports, and ground-mount systems where predictable yield and long-term reliability are paramount.

Common questions

6 answered
How does the bifacial ZNShine ZXM7-SHLDD120 panel differ from a standard monofacial module?
The ZXM7-SHLDD120 uses bifacial technology, generating power from both the front and rear sides. The rear side captures light reflected from the roof, ground, or light-colored surfaces, delivering an additional energy gain, especially over bright surfaces or in ground-mounted installations. Under typical mounting conditions this results in higher output from the same roof area compared to a monofacial module of similar power.
What warranty comes with ZNShine ZXM7-SHLDD120 panels?
The manufacturer provides a 12-year product warranty covering material and workmanship defects, plus a 30-year power performance warranty guaranteeing a minimum energy output level throughout that period. This is standard for modern glass-glass modules, which age better over time than traditional backsheet panels.
Does the glass-glass construction of the ZXM7-SHLDD120 require special mounting?
No, glass-glass modules are installed on standard PV mounting systems, respecting the mounting points specified by the manufacturer. This construction is stiffer and more resistant to moisture and mechanical loads than backsheet panels, making it well suited for residential roofs, ground-mounted systems, and carports without any additional protective measures.
Are ZXM7-SHLDD120 panels resistant to PID degradation?
Yes, the ZXM7-SHLDD120 series offers high resistance to PID degradation, the power loss caused by voltage potential differences within an installation. This matters especially in large systems with long strings and high system voltage. The PERC cells used in this series are designed to minimize this effect, resulting in more stable energy production over the panel's lifetime.
How does the ZXM7-SHLDD120 panel perform in low light or partial shading?
Thanks to its half-cut, multi-busbar architecture, the module reduces resistive losses and handles partial shading better, for example when a chimney or nearby building casts a shadow. The panel also performs well under diffuse light, on cloudy days, or in early morning and evening hours, resulting in more stable annual energy yield rather than performance limited to full-sun conditions.
What is the maximum power output of the ZNShine ZXM7-SHLDD120 and what installations is it suited for?
Modules in this series reach a maximum power output of up to 465 Wp. Combining high power, bifacial technology, and durable glass-glass construction, they suit residential installations on pitched roofs as well as larger commercial systems, carports, and ground-mounted installations where predictable energy production over many years is essential.
