Yingli YL590D-41f 1/2 580–605W PERC Monocrystalline Solar Panel
Model YL590D-41f 1/2 | PERC | 120 Half-Cell | Monofacial | 1500V System Voltage
Product Overview
The Yingli YL590D-41f 1/2 is a high-output monocrystalline PERC solar panel built for strong performance and long-term reliability. It delivers up to 605 Wp of power and reaches a maximum module efficiency of 21.4%. The half-cell design supports lower resistive losses and stable energy generation in demanding conditions. With a 120-cell layout, tempered glass, and an anodized aluminium frame, this module is designed for commercial and utility-scale installations. Its 1500V system rating and positive power tolerance make it a dependable choice for efficient solar projects. The panel is also backed by solid warranty coverage and proven durability specifications.
Key Benefits
High Power Output: The module reaches 605 Wp, supporting strong energy production in large-scale systems.
Excellent Efficiency: Efficiency goes up to 21.4%, helping maximize usable energy from available roof or ground space.
PERC Cell Technology: PERC architecture improves light capture and supports better performance under varied operating conditions.
Durable Construction: Tempered glass, anodized aluminium, and an IP-rated junction box support reliable outdoor use.
Long-Term Value: The warranty structure includes 12 years product coverage and 25 years of power performance protection.
Flexible System Design: A 1500V maximum system voltage and 30A fuse rating support modern string configurations.
How It Works
This solar panel converts sunlight into electrical power through monocrystalline PERC cells arranged in a 120 half-cell format. The half-cell layout reduces internal resistance and helps maintain output during partial shading. The panel’s electrical design is optimized for stable voltage, current, and performance across standard and real-world operating conditions. Its tempered glass surface protects the cells while allowing light to pass through efficiently. The anodized aluminium frame adds structural support, and the junction box helps manage safe power delivery in demanding installations.
PERC Cell Conversion: PERC cells capture sunlight efficiently and convert it into usable DC electricity. This supports strong output in both commercial and utility applications.
Half-Cell Electrical Layout: The half-cell structure lowers resistive loss inside the module. It also helps improve performance when part of the panel is shaded.
System Integration: With a 1500V system voltage rating, the module fits modern string inverter designs. This makes planning and deployment more efficient for larger projects.
