Solar Panel Energy Efficiency and Degradation
The degradation of solar panels refers to the gradual reduction in their energy, efficiency, or performance over time.
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.
The degradation of photovoltaic (PV) systems is one of the key factors to address in order to reduce the cost of the electricity produced by increasing the operational lifetime of PV systems. To reduce the degradation, it is imperative to know the degradation and failure phenomena.
The output power of a single PV panel decreases from its initial rated capacity of 430 W to around 389 W, corresponding to an average annual degradation rate of approximately 0.48%, which aligns with the theoretical expectation of 0.4%–0.5% per year. 20-year photovoltaic system efficiency degradation rate under theoretical environment.
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.
To sum up, the gradual decline in efficiency or degradation impacts the long-term performance of solar panels. It depends on the manufacturing processes; however, industry standards often include degradation warranties that specify the expected loss of efficiency over a certain number of years.
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.
