Yingli 550W Mono PERC Solar Panel

Overview of the Yingli 550W Solar Panel

The Yingli 550W solar panel from the YLM-J 3.0 PRO series is a high-power monocrystalline PERC photovoltaic module designed for residential, commercial, and utility-scale solar installations. With a proven glass-backsheet construction and half-cell design, this panel delivers strong energy yield, mechanical durability, and reliable long-term performance.

What the Yingli 550W Panel Is Designed to Do

This solar panel converts sunlight into DC electrical energy and is designed to:

• Deliver high power output per module to reduce overall system costs
• Improve real-world energy yield through half-cell and multi-busbar design
• Operate reliably in harsh environmental conditions
• Provide stable long-term performance with low degradation

What This Panel Is Not

This product is a photovoltaic module only.
