About How to check the age of photovoltaic panels
Key takeaways. Solar panels generally last for 25 to 30 years. Solar panels slowly degrade, resulting in less and less electricity production over time. Solar panels can produce power after 25 to 30 years but at a significantly lower rate than their original output.

The industry standard for solar panels’ lifespan is 25 to 30 years. Most solar panel manufacturers provide production warranties that extend for at least 25 years.
Most PV systems are young—approximately 70% of solar energy systems in existence have been installed since 2017. The estimated operational lifespan of a PV module is about 30-35 years, although some may produce power much longer.
The answer to how long a solar panel last significantly depends on the brand of the panels, location, weather conditions, and the maintenance routine. Solar panels can last up to 25 years. With proper maintenance, they are sure to last longer.

6 FAQs about [How to check the age of photovoltaic panels]
How often does solar panel degradation occur?
While PV technology has been present since the 1970s, solar panel degradation has been studied mainly in the last 25 years. Research Institutes like NREL have estimated that appropriate degradation rates of solar panels can be set at 0.5% per year with current technology. What is the impact of solar panel degradation on your PV system?
How do I know if my solar panels are good?
For homeowners, a valuable resource for evaluating solar panel quality is the PVEL (PV Evolution Labs) scorecard [which] assesses the reliability and performance of solar panels through series of tests. Panels that perform well on PVEL tests will show resilience to environmental factors that can cause damage to the panels.
Can manufacturing techniques extend the lifespan of solar panels?
Improving manufacturing techniques may reduce solar panel degradation and extend the lifespan of PV modules. The U.S. Department of Energy Solar Energy Technologies Office is currently funding a research team to develop techniques that could extend the lifespan of PV modules to up to 50 years or more.
Do solar panels need to be replaced after 15 years?
As mentioned, solar panel replacement after 15 years isn’t necessary unless the panel is damaged. However, the system decreases in efficiency over time. While the panel won’t die after its 25-year lifespan, it will significantly reduce efficiency in its output.
How does aging affect solar panels?
Aging is the main factor affecting solar panel degradation, this can cause corrosion, and delamination, also affecting the properties of PV materials. Other degrading mechanisms affecting PV modules include Light-Induced Degradation (LID), Potential-Induced Degradation (PID), outdoor exposure, and environmental factors.
How often should you replace a solar inverter?
Most solar inverters are warranted for a shorter time compared to the PV panels. Predictably, most solar system failures occur with the inverter as the following graph shows: So, since the lifespan of solar panels is often more than twice that of your inverter, plan on replacing the inverter once, twice, or even more for your array.
