Yingli Solar YL605D-41f 1/2 605W PERC Monocrystalline Solar Panel
Model YL605D-41f 1/2 | PERC | 120 Half-Cell | Monofacial | 1500V System Voltage
Product Overview
The Yingli Solar YL605D-41f 1/2 is a high-output monocrystalline solar panel designed for demanding commercial and utility-scale projects. It combines PERC technology with a 120 half-cell layout to support strong energy yield and reliable field performance. With a maximum power output of 605 Wp and module efficiency reaching 21.4%, it is built for installations where space efficiency matters. The module also features a positive power tolerance and a durable construction, helping deliver dependable long-term generation. Its 1500V system voltage compatibility supports modern solar array designs and efficient system planning.
Key Benefits
High Power Output: Delivers up to 605 Wp for strong generation in large-scale solar systems.
Excellent Efficiency: Reaches 21.4% module efficiency to maximize output from available roof or ground space.
PERC Technology: Uses proven PERC cell design to improve light capture and overall energy performance.
Durable Construction: Tempered glass, anodized aluminium, and IP-rated junction box protection support long-term reliability.
Strong Warranty Support: Includes a 12-year product warranty and a 25-year power warranty for added confidence.
Low Degradation Profile: Supports long service life with 2.00% first-year degradation and 0.55% annual degradation afterward.
How It Works
This module converts sunlight into usable electricity through advanced monocrystalline cells and a PERC-enhanced structure. The half-cell design helps reduce resistive losses and supports stable performance under real operating conditions. High electrical ratings, strong thermal behavior, and robust materials all work together to maintain output over time. The panel is suited to modern solar systems that need high power density, dependable voltage characteristics, and efficient string design. Its specifications also support installation in environments that require broad operating tolerance and long-term durability.
Sunlight Conversion: The monocrystalline cells absorb solar radiation and convert it into direct current electricity. PERC architecture improves the cell’s ability to capture and use light efficiently.
Half-Cell Power Flow: The 120 half-cell layout helps distribute electrical current more evenly across the module. This design can reduce internal losses and support consistent output.
System Integration: The module’s voltage and current values are designed for straightforward integration into larger PV arrays. Its 1500V compatibility supports efficient system planning for commercial projects.
