Technology Comparison

PERC vs Mono: What’s the Difference?

Understanding PERC vs Mono technology is key in the longi vs jinko solar panels decision.

• Monocrystalline (LONGi):
  
  
  • Made from a single silicon crystal
    
    
  • Typically offers higher efficiency
    
    
  • Performs well in low-light conditions
    
    
  • Known for longevity and premium aesthetics
    
    
• PERC (Jinko):
  
  
  • Passivated Emitter Rear Cell technology
    
    
  • Adds a reflective layer to improve sunlight capture
    
    
  • Increases output during early morning and late afternoon
    
    
  • Affordable and widely used in residential systems
    
    

While both technologies are effective, monocrystalline panels from LONGi generally offer slightly better efficiency in Australia’s climate. However, PERC panels from Jinko provide exceptional value for the price.

Efficiency Ratings & Degradation

Let’s break down their efficiency and durability over time.

• LONGi:
  
  
  • Efficiency ranges from 21.0% to 22.3%

  • Expected power output retention after 25 years: ~84%
    
    
• Jinko:
  
  
  • Efficiency ranges from 20.5% to 21.6%
    
    
  • Annual degradation rate around 0.50%
    
    
  • Expected output retention after 25 years: ~83%
    
    

The real difference in longi vs jinko solar panels comes down to efficiency over decades—LONGi holds a slight edge.

Warranty and Reliability

  • Higher upfront cost per watt

  • Shorter payback period when matched with high sunlight exposure
