How much power does a solar panel lose a 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.
What is a solar panel degradation rate?
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. Your panels should still be producing around 90% of their original output after 20 years.
How much do solar panels deteriorate a year?
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.
