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%
- Annual degradation rate around 0.45%
- 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

In Australia, durability matters. You want panels that can handle high heat, sudden storms, and dust buildup. Here’s how each brand stands out:

LONGi:
- 12-year product warranty
- 25-year performance warranty
- High resistance to environmental stress
Jinko:
- 12 to 15-year product warranty (depending on the model)
- 25-year performance warranty
- Known for strong quality control and fewer defects

Backed by Esteem Energy, both LONGi and Jinko panels come with full installation support and warranties honored through our CEC-accredited installer network.

Cost vs Value

Budget is a major factor when comparing longi vs jinko solar panels, especially for homeowners wanting fast returns.

LONGi:
- Higher upfront cost per watt
- Ideal for those prioritizing long-term performance
- Shorter payback period when matched with high sunlight exposure
Jinko:
- Lower upfront cost per watt
- Attractive to homeowners on a budget
- Slightly longer payback in lower-efficiency zones but great ROI

The decision ultimately depends on your energy goals—lower upfront investment with Jinko or higher lifetime value with LONGi.
