Yingli YL585D-41f 1/2 585W PERC Monocrystalline Solar Panel
Model YL585D-41f 1/2 | PERC | 120 Half-Cell | Monofacial | 1500V System Voltage
Product Overview
The Yingli YL585D-41f 1/2 is a high-output monocrystalline solar panel built for dependable energy production. This PERC module combines a 585W rating with strong module efficiency and a durable 120 half-cell layout. It is designed for commercial and utility-scale projects that need stable performance, compact installation value, and long service life. The panel uses tempered glass, an anodized aluminium frame, and IP68 junction box protection for reliable outdoor operation. Its positive power tolerance and long-term degradation profile support consistent system yield over time.
Key Benefits
High Power Output: Delivers up to 585W for strong energy generation in demanding installations.
Efficient PERC Design: Uses PERC technology to help improve light capture and electrical performance.
Half-Cell Construction: 120 half-cells help reduce resistive losses and support better shading tolerance.
Durable Build: Tempered glass and an anodized aluminium frame are used for long-lasting strength.
Long-Term Value: Warranty coverage and low annual degradation support reliable output over many years.
How It Works
The YL585D-41f 1/2 converts sunlight into usable direct current through monocrystalline cells arranged in a 120 half-cell format. Its PERC structure improves rear-side light utilization, which helps the module extract more energy from available sunlight. The half-cell layout also reduces electrical resistance, which supports efficient operation and helps minimize power losses. In real-world use, the panel performs across a wide temperature range and remains suitable for large rooftop and ground-mount systems. Its electrical design, mechanical build, and environmental ratings work together to support steady output and dependable system integration.
PERC Cell Conversion: The cells absorb sunlight and convert it into electrical energy. PERC optimization helps increase light-use efficiency.
Half-Cell Current Flow: The 120 half-cell layout lowers internal resistance. This supports better electrical performance under operating conditions.
System Integration: The module works within 1000V or 1500V systems, depending on project design. That flexibility helps simplify planning for commercial arrays.
