Silfab SIL-520 XM 520W Bifacial Solar Panel
Model SIL-520 XM Bifacial | N-Type Silicon | 132 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The Silfab SIL-520 XM Bifacial is a high-performance commercial solar panel built for strong energy output and long-term reliability. It uses N-type silicon cell technology and a bifacial design to capture light from both sides. That helps improve energy yield in real-world installations. With 520 Wp rated power and 21.9% module efficiency, it delivers excellent power density for rooftops and larger solar arrays. Its anodized aluminum frame, tempered glass, and IP68-rated junction box support durability in demanding conditions. This model is designed for projects that need consistent performance, strong warranties, and dependable operation across a wide temperature range.
Key Benefits
High Power Output: The module delivers 520 Wp for strong commercial energy generation.
Bifacial Design: Rear-side light capture can improve total energy harvest in suitable installations.
N-Type Cell Technology: Next-generation cells support strong efficiency and long service life.
Low Degradation: The panel is rated for a 0.36% annual degradation rate and stable long-term output.
Commercial Durability: Tempered glass, anodized aluminum, and high load ratings improve installation resilience.
Broad Compatibility: A 1500V maximum system voltage supports modern commercial solar system designs.
How It Works
This solar panel converts sunlight into usable electricity through advanced N-type silicon cells. Its half-cell layout helps reduce internal resistance and improves performance under partial shading. The bifacial construction also allows reflected light to be captured from the rear side. That can increase total generation in bright, open, or reflective environments. The module is engineered to work efficiently in high temperatures, low-light conditions, and long operating cycles. Its electrical design supports stable voltage, controlled current flow, and reliable system integration for commercial projects.
N-Type Half-Cell Architecture: The 132 half-cell structure improves current handling and reduces power loss. It also helps maintain better performance under shade.
Bifacial Energy Capture: The panel absorbs sunlight from the front and rear sides. That can increase output when installed above reflective surfaces.
Temperature-Aware Performance: The low temperature coefficient supports stronger output in hot climates. This helps preserve performance during high-temperature operation.
