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.
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?
Potential-Induced Degradation or PID is another degradation mechanism affecting PV modules and reducing their efficiency. Unlike LID, PID does not heavily affect a particular type of PV module, but it affects mono c-Si, polycrystalline silicon (poly c-Si), and thin-film PV modules alike.
Moreover, differences in the PV installation affect the degradation rate. Thin-film technologies such as CIS/CIGS (0.900 %pt.), CdTe (1.127 %pt.), and a-Si (0.599 %pt.) were associated with significantly higher annual degradation compared to the base group of crystalline silicon, a result in line with prior literature [8, 9].
