Learn MoreWhile 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 comprises a series of mechanisms through which a PV module degrades and reduces its efficiency year after year. Aging is the main factor affecting solar panel degradation, this can cause corrosion, and delamination, also affecting the properties of PV materials.
Degradation is a normal, unavoidable part of owning solar panels. Nothing lasts forever, but the savings your solar system generates for you throughout its useful life could be saved or reinvested into your website.
1. Introduction Utilizing solar PV to generate energy is not a simple operation due to degradation, which can result in a reduction in solar PV performance and efficiency [1, 2]. According to recent studies, the rate of degradation varies between 0.6% and 0.7% per year [3, 4].
One way solar panel degradation happens is through microcracks that form in the silicon of the solar cells. These small cracks cause electrical connections to deteriorate, meaning there are fewer paths for those electrons from the sun to take, and thus less energy goes to your inverter and into your home, business, or farm.
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.
