The Silfab NTC series redefines performance standards through the use of advanced N-type cell technology in TopCon architecture. This solution eliminates light-induced degradation (LID), which translates into significantly higher stability of energy yields throughout the entire life cycle of the installation. These panels are characterized by exceptional efficiency even in demanding lighting conditions, making them an ideal choice for investors looking to maximize self-consumption with limited roof space. Thanks to the use of bifacial light absorption in selected models, the NTC series allows for the efficient utilization of reflected radiation, which sets it apart from standard monofacial modules. The construction has been optimized for extreme mechanical loads, guaranteeing safety in the variable Polish climate. The all-black finish aesthetic ensures the modules blend perfectly with modern architecture, combining elegance with industrial durability. It is a solution dedicated to the premium segment, where the priority is the highest reliability and a long-term power warranty. Silfab NTC is the response to the needs of the most demanding prosumers who expect technology resistant to the passage of time and changing weather conditions, offering a clear technological advantage over popular P-type cells.

Common questions

6 answered
How does Silfab NTC cell technology compare to standard PERC panels?
Silfab NTC uses N-type TOPCon cells instead of the P-type cells found in PERC modules. The key advantage is the complete elimination of LID (Light Induced Degradation), which causes conventional panels to lose power during the first months of operation. N-type cells also deliver a superior temperature coefficient (approx. -0.29%/°C), meaning less output loss on hot days compared to typical PERC modules.
What warranty does Silfab offer on the NTC series and what does it cover?
The Silfab NTC series comes with a 25-year product warranty and a 30-year linear power performance warranty. After 30 years of operation, the panel should retain at least 89% of its rated output. This is one of the longest power warranties available in the PV market, reflecting the manufacturer's confidence in the long-term durability of this series.
What is the maximum power output of the Silfab NTC series and is it enough for a small roof?
The highest available power in the Silfab NTC series is 530 Wp. The high power density makes this series particularly well-suited for rooftop installations with limited space, where every square meter must work as efficiently as possible. This allows maximizing total system capacity without increasing the roof area used.
Do Silfab NTC panels perform well in winter and overcast conditions?
Yes, N-type TOPCon technology excels in low-irradiance conditions. These cells respond better to diffuse light than standard P-type modules, which is especially significant in climates where a large portion of annual energy production occurs during autumn and winter months. The result is a higher annual energy yield in real-world operating conditions.
Are Silfab NTC panels available in an all-black finish and how do they look on a roof?
Yes, the NTC series is available in an all-black configuration with a black frame and black backsheet. This option is popular among homeowners who value a sleek, uniform appearance, especially on prominent roof sections or in residential and urban settings. The aesthetic finish has no negative impact on the technical specifications or module durability.
Is Silfab a reliable manufacturer and what does Tier 1 status mean for the NTC series?
Silfab Solar is a Canadian manufacturer holding Tier 1 status from independent industry analysts, indicating top-tier financial stability and manufacturing consistency. The company operates its own production lines in North America. The NTC series targets the premium segment, backed by comprehensive 25-year product and 30-year linear performance warranties issued directly by the manufacturer.
