A typical degradation rate for solar panels is between 0.5% and 0.8% per year. This means a panel might produce 12-15% less power after 25 years. What Causes Solar Panel Degradation?
This means that a solar panel's power output will decrease by 0.5-0.8% each year compared to its initial rated output. However, the actual degradation rate can range from as low as 0.2% to as high as 1% annually, depending on the quality and materials used in the panel. To illustrate the impact of degradation, consider a 250-watt solar panel.
Solar panels are a great way to harness energy from the sun, but they don't last forever. Over time, solar panels lose efficiency, which is known as degradation. Understanding how and why this happens can help you make informed decisions about your solar energy investment.
Solar panel degradation is a gradual decline in efficiency due to exposure to sunlight and weather. Most solar panels degrade at a rate of about 0.5% per year, meaning they still work well for many years. Quality of materials and installation practices greatly affect how quickly solar panels degrade.
The solar panel degradation curve shows an average solar panel degradation per year of about 1%. Most warranties guarantee 90% efficiency after 10 years and 80% after 25–30 years.
