The ZNShine ZXM7-UHLDD120 series are bifacial modules featuring a double glass construction, designed to truly boost the yield not only from the front side but also from the reflected ground light. In practice, this means higher energy production on flat-roof installations with light membranes, carports, and ground-mounted systems where albedo is significant.

The application of N-type TOPCon cells helps limit long-term losses and improves performance in poorer weather conditions - common in Poland's climate. As a result, this series performs well where stable annual performance matters more than just catalog parameters.

It also operates better than many standard P-type modules due to its PID resistance and robust construction, ensuring reliability in demanding environments (humidity, temperature fluctuations, mechanical loads). This is the choice for commercial investors and prosumers who want to maximize the yield from the same surface area and minimize the risk of performance degradation over time.

Common questions

6 answered
What is the difference between ZNShine ZXM7-UHLDD120 bifacial modules and standard mono-facial panels?
ZXM7-UHLDD120 series modules have active cells on both sides of the glass, capturing additional light reflected from the ground (roof, gravel, white membrane). In practice this delivers extra energy yield of several to over ten percent compared to a mono-facial panel of the same power, especially on flat roofs and ground-mount installations with a light-colored surface.
What warranty comes with ZNShine ZXM7-UHLDD120 solar panels?
The manufacturer covers the ZXM7-UHLDD120 series with a 12-year product warranty against material and workmanship defects, plus a 30-year linear power warranty guaranteeing a defined percentage of rated output over that period. This is standard for Tier 1 panels using N-type TOPCon cells and gives investors confidence in long-term system profitability.
What is TOPCon technology and why is it better than standard P-type cells?
TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that reduces light-induced degradation (LID) losses and performs better at higher temperatures and under weaker irradiance than typical P-type cells. In a module rated up to 485 Wp, this translates into higher efficiency and more stable annual yield, particularly relevant in climates with frequent diffuse light.
Are ZNShine ZXM7-UHLDD120 panels suitable for flat roofs or carports?
Yes, the bifacial, dual-glass construction is specifically designed for flat roofs with a light membrane, carports, and ground-mount installations, where the module can capture light reflected off the ground (albedo effect). To achieve a real production boost, modules are typically installed on racking with some clearance from the surface below.
Are ZXM7-UHLDD120 series panels resistant to PID and moisture?
Yes, the series has PID (Potential Induced Degradation) resistance, preventing power losses caused by leakage currents at high system voltages. The robust dual-glass build also protects the cells against moisture and fluctuating weather conditions, supporting stable performance throughout the warranty period.
How much power do ZNShine ZXM7-UHLDD120 panels produce and how many are needed for a typical home system?
Modules in this series reach up to 485 Wp of maximum power. For a typical residential system of 5-8 kWp, roughly 10 to 17 panels are needed, depending on the specific power variant and household energy demand. ZNShine is a Tier 1 manufacturer, which simplifies financing and insuring the installation.
