All solar panels degrade over time, although their rates differ. And this difference between degradation rates can prove out to be significant at the end of your solar panel’s useful life. While a good quality panel may degrade by only 9%, a cheaper panel could lose 20% or more of its efficiency. Let’s understand this with the help of an example.
Solar panels, like other technology, will produce less energy with time. The degradation rate results in a reduction in power production. The median solar panel degradation rate is around 0.5% per year, which indicates that the energy output of a solar panel will drop by 0.5% every year.
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?
Solar panel degradation caused by LID heavily affects heavily modules manufactured with mono-crystalline silicon, especially p-type wafer ones. LID effect is also higher in PERC modules. Potential-Induced Degradation or PID is another degradation mechanism affecting PV modules and reducing their efficiency.
Appropriate degradation rates of solar panels are estimated at 0.5% per year considering a well-maintained PV system featuring ideal conditions. However, solar panel degradation rates can reach up in some extreme cases, going as high as 1.4% or 1.54% per year.
In the past, solar panels would typically see a decrease of 1% or more in power output each year. This is known as the solar panel degradation rate. According to a 2012 study by The National Renewable Energy Laboratory (NREL), modern solar panels show no more than 0.8% loss of power per year.
