Solar panel degradation refers to the gradual decline in performance and efficiency of solar panels over time. Understanding the degradation rates is crucial for assessing the long-term performance and lifespan of solar panels. In this blog post, we’ll delve into a comprehensive solar panel degradation chart over 25 years, including yearly degradation rates and remaining efficiency at the end of 25 years. Immortals Solar provides insights into sustainable energy solutions and optimal solar panel performance.
Solar Panel Degradation Chart Over 25 Years:
| Years in Operation | Degradation Rate (%) | Remaining Efficiency (%) |
|---|---|---|
| 1 | 1-2 | 98-99 |
| 2 | 0.5-1.5 | 97.5-98.5 |
| 3 | 0.5-1 | 97-99 |
| 4 | 0.5 | 96.5 |
| 5 | 0.5 | 96 |
| 6 | 0.5 | 95.5 |
| 7 | 0.5 | 95 |
| 8 | 0.5 | 94.5 |
| 9 | 0.5 | 94 |
| 10 | 0.5 | 93.5 |
| 11-25 | 0.5 | 90-92 |
Understanding Yearly Degradation Rates:
- First-Year Degradation: Typically, solar panels experience higher degradation in the first year of operation, ranging from 1-2%.
- Stabilizing Degradation: Subsequent years see a stabilization in degradation rates, usually around 0.5-1% per year.
- Long-Term Performance: Solar panels can maintain high performance levels with minimal degradation beyond the initial years of operation.
Remaining Efficiency at the End of 25 Years:
- At the end of 25 years, solar panels may retain approximately 90-92% of their original efficiency, showcasing their long-term durability and sustainability.
Factors Influencing Degradation:
- Environmental Factors: Exposure to sunlight, temperature variations, and weather conditions can impact degradation rates.
- Quality of Panels: High-quality solar panels with superior materials and manufacturing processes may experience slower degradation rates.
- Maintenance: Regular maintenance and cleaning can help mitigate degradation and ensure optimal panel performance.
Importance of Solar Panel Longevity:
- ROI Consideration: Understanding degradation rates is essential for calculating the return on investment (ROI) of solar panel installations.
- Sustainable Energy: Long-lasting solar panels contribute to sustainable energy solutions by maximizing energy production over their lifespan.
- Warranty Coverage: Many solar panel manufacturers offer warranties that guarantee performance levels and degradation rates over a specified period.
