The ZNShine ZXM7-SHW144 series is designed as a lightweight, reinforced PV module for installations where construction safety and easier installation logistics matter. The application of monocrystalline PERC half-cut cells, combined with a multi-string connection system, helps minimize internal losses and stabilize module performance, which is particularly important during partial shading and uneven roof surface heating. In practice, this translates to more predictable yields and fewer service issues over the long term.

Another notable feature is its high resistance to PID, a phenomenon that can reduce installation efficiency in high humidity conditions and with long strings. The series also offers excellent performance in low light conditions, which translates to better energy production on cloudy days and during morning hours. This solution is ideal for commercial, industrial, and larger domestic installations, where efficiency, durability, and risk control are key.

Common questions

6 answered
What is the maximum power output of the ZNShine ZXM7-SHW144 panel and what does it depend on?
Panels in the ZXM7-SHW144 series reach a maximum power of up to 550 Wp. This is achieved through monocrystalline PERC half-cut cells combined with a multi-busbar design that reduces internal current losses within the module. As a result, the panel makes efficient use of the available surface area and maintains high efficiency even under partial irradiance.
Are ZNShine ZXM7-SHW144 panels suitable for roofs with limited load capacity?
Yes, the ZXM7-SHW144 series is engineered as a lightweight, reinforced PV module, which matters for roofs with limited structural load capacity or challenging rooftop logistics. The reinforced frame increases resistance to snow and wind loads, an important factor in Polish climate conditions, particularly during winter.
What warranty comes with ZNShine ZXM7-SHW144 panels?
The manufacturer provides a 10-year product warranty and a 25-year power performance warranty. This means the panel should retain its rated power percentage over a quarter of a century, and any material or manufacturing defect within the first decade is covered by repair or replacement under the manufacturer's warranty.
What is PID resistance and why does it matter in the ZXM7-SHW144 series?
PID (Potential Induced Degradation) is a cell degradation phenomenon caused by voltage potential differences in long strings, worsened by high humidity and temperature. High PID resistance in the ZXM7-SHW144 series reduces the risk of power loss over the module's lifetime, resulting in more stable energy yields, especially in large commercial installations with long module strings.
Do ZNShine ZXM7-SHW144 panels perform well on cloudy days?
Yes, the series is known for strong low-light performance, a valuable feature in Poland's climate with frequent overcast days. PERC half-cut cells capture diffuse sunlight more effectively than standard cells, translating into higher energy production during early mornings, late afternoons, and cloudy weather.
Is ZNShine a Tier 1 manufacturer and what does that mean for buyers?
Yes, ZNShine holds Tier 1 manufacturer status, indicating strong financial credibility, a long-standing market presence, and bankability - a key criterion for installations financed through loans or leasing. For end customers, this translates into greater confidence in warranty fulfillment and consistent quality across serial module production.
