A Comprehensive Review of Solar Panel Performance Degradation
This paper presents a comprehensive review of solar panel performance degradation in both industrial and residential sectors. Drawing on a wide range of academic studies, the paper
This review paper aims to evaluate the impact of defects on the reliability and degradation of photovoltaic (PV) modules during outdoor exposure. A comprehensive analysis of existing literature was conducted to identify the primary causes of degradation and failure modes in PV modules, with a particular focus on the effect of defects.
According to the study conducted at the AEC PV Test Facility, three systems were used to assess the performance degradation of photovoltaic modules over a two-year period. The results from all three systems indicate that degradation rates ranged from 0.6% to 1.5% per year.
These include degradation due to long-term exposure to strong UV radiation, the effect of high-energy particles and inevitable sealing defects introduced during the manufacturing process of PV modules. The degradation of PV modules is a critical concern as it directly impacts the long-term stability and economic feasibility of PV systems .
In a real-world environment, other factors such as moisture ingress, package ageing and hot-spot effects can still contribute to accelerated degradation of PV modules. Performance degradation over time can significantly impact the long-term economic efficiency of PV systems .
