Solar panels are designed to last for many years, with a typical lifespan of:
- 25 years or more for high-quality panels
- 20-25 years for standard panels
- 15-20 years for lower-quality panels
Over time, solar panels may experience a gradual decline in efficiency due to:
- Degradation of photovoltaic cells
- Exposure to environmental factors (temperature, humidity, UV radiation)
- Micro-cracks and physical damage
However, even after 25 years, solar panels can still produce around 80-90% of their original power output.
Factors affecting solar panel lifespan:
- Quality of the panel
- Environmental conditions (temperature, humidity, etc.)
- Maintenance and cleaning
- Installation quality
- Technology advancements (newer panels may last longer)
To ensure optimal performance and longevity:
- Regularly clean and inspect panels
- Monitor system performance
- Address any issues promptly
- Consider upgrading to newer technology
Keep in mind that solar panels are a long-term investment, and their lifespan is just one aspect to consider when evaluating their value and performance.
