Silfab Prime NTC 420W N-Type All-Black High-Efficiency Solar Panel SIL-420-QD
SIL-420-QD
Silfab 420W SIL-420-QD – 420W N-Type All-Black High-Efficiency Solar Panel
The Silfab SIL-420-QD is a high-efficiency, all-black monocrystalline solar panel engineered with next-generation N-Type cell technology. This 108 half-cell module delivers enhanced durability, low degradation, and superior performance in shaded, low-light, and high-temperature environments—making it ideal for residential and commercial rooftop solar systems.
Key Benefits
- High Efficiency: 420W output with 21.5% module efficiency for superior energy yield per square foot.
- Low Light & Shade Tolerance: Performs optimally even under cloud cover or partial shading.
- Durability in Harsh Conditions: Engineered to endure 5400 Pa front and 4000 Pa rear load (snow/wind).
- Long-Term Value: Reduced degradation rate ensures 89.3% power output at 30 years.
- Premium Aesthetics: Sleek black anodized frame with all-black cell design for a seamless rooftop appearance.
Special Technology
- N-Type Half-Cut Cells: Delivers greater efficiency, better thermal performance, and reduced LID/PID degradation.
- Next-Gen Tempered Glass: 3.2 mm high-transmittance, anti-reflective coated glass for optimal light absorption.
- Fluorine-Free Backsheet: Multi-layer dielectric film offers high UV and hydrolysis resistance.
- IP68-Rated Junction Box: Certified to UL 3730 and IEC 62790, with 3 integrated bypass diodes for safety.
What are N-Type Panels?
N-Type solar panels represent the next evolution in photovoltaic technology. Unlike traditional P-Type cells, N-Type cells use phosphorus-doped silicon, which creates a more stable and efficient structure. This fundamental difference leads to several key advantages:
- Higher Efficiency: N-Type cells generally boast higher conversion efficiencies, meaning they can convert more sunlight into electricity from the same surface area.
- Lower Degradation: They are inherently less susceptible to light-induced degradation (LID) and potential induced degradation (PID), phenomena that can cause power loss in solar panels over time. This ensures more stable and predictable energy output throughout the panel's lifespan.
- Improved Temperature Coefficient: N-Type panels perform better in high-temperature environments, experiencing less power loss as temperatures rise, which is crucial for real-world energy production.
Warranty
Silfab backs the SIL-420-QD panel with a 25-year product warranty and a 30-year linear performance guarantee ensuring:
- ≥ 98% output at year 1
- ≥ 90.8% at year 25
- ≥ 89.3% at year 30
Best Uses
- Residential Rooftops: All-black aesthetics paired with high energy output from limited space.
- Commercial Systems: Suitable for large rooftops or carports requiring long-term performance and low maintenance.
- Extreme Environments: Ideal for high heat, snow load, or coastal conditions.
