The ZNShine ZXM7-SHLDD108 series delivers genuine energy gains in variable conditions, including on roofs not optimally oriented throughout the day. The key advantage is the bifacial glass-glass construction, enabling the panel to generate power not only from front-facing sunlight but also from reflected light off the ground. In practice, this means higher productivity on light-colored roofs, carports, ground-mounted structures, and any installation where every additional kilowatt-hour counts.

The series incorporates PERC technology and half-cut cells, helping minimize losses and improve module performance under partial shading. Furthermore, it features PID resistance, crucial for installations operating year-round under high voltage, along with a watertight connection box and reinforced structure, ensuring reliability in challenging outdoor conditions.

This is an excellent choice for residential and commercial installations prioritizing stable energy yield, longevity, and predictable performance in the Polish climate.

Common questions

6 answered
How does TOPCon cell technology in the ZNShine ZXM7-SHLDD108 series differ from older PERC cells?
TOPCon (N-type) cells used in this series offer higher efficiency and lower long-term degradation than classic PERC (P-type) cells. The additional passivation layer reduces current losses and performs better under high temperatures and low-irradiance conditions. In practice, this means higher energy yield from the same roof area and a slower power drop over the module's lifetime.
How much extra energy does bifaciality add to the ZXM7-SHLDD108 panels?
The glass-glass design allows the panel to capture light reflected from the ground, which on bright surfaces (white roofing, gravel, snow) can add up to 25 percent extra power gain from the rear side. The actual result depends on ground albedo and mounting height, so these modules perform best on carports, ground-mount structures, and flat roofs rather than a typical sloped roof flush with the surface.
What warranty applies to ZNShine ZXM7-SHLDD108 modules?
The manufacturer provides a 12-year product warranty and a 30-year linear power warranty, guaranteeing 87.4 percent of initial power output after 30 years of operation. This is a standard typical of premium N-type panels, letting you plan the installation as a long-term investment without worrying about rapid performance decline.
Are ZXM7-SHLDD108 panels suitable for a single-family home roof, or only for commercial installations?
With a max power of up to 440 Wp and dimensions of 1722x1134 mm, these panels work well for both residential and commercial installations. The glass-glass construction is heavier than a standard backsheet panel (about 24.5 kg), so roof load capacity should be checked, especially on older roofing. On light-colored roofs and free-standing structures, bifaciality delivers a noticeably higher return.
Is ZNShine a Tier 1 manufacturer, and can you trust such a long warranty?
Yes, ZNShine PV-Tech is a Chinese manufacturer with a long production history, classified as Tier 1, which indicates financial stability and reliability in honoring warranty commitments. Additionally, an IP68-rated junction box and reinforced frame improve resistance to moisture and harsh weather, supporting the 30-year power warranty.
Do ZXM7-SHLDD108 panels perform well in winter and low temperatures?
Yes, TOPCon cells have a favorable temperature coefficient and a good response to weak, diffuse light, which translates into better energy production on cloudy winter days and during early morning or late afternoon hours. The bifacial design also captures light reflected off snow, which has very high albedo, potentially noticeably increasing rear-side yield in winter conditions.
