Table 9 presents the calculated degradation rates of the monocrystalline PV panels over the 5-year period. The results indicate that the annual degradation rate ranges from 0.282% to 0.354%, with an overall average degradation rate of 0.861% to 0.886% per year. Table 8. The EL results of two monocrystalline PV panels after 5 years of operation.
Degradation of monocrystalline PV panels after 5 years of operation. The EL images of the monocrystalline solar panel, as shown in Fig. 5, reveal performance degradation caused by defects such as micro-cracks and folds, which create shaded areas and reduce the panel’s ability to convert solar energy into electricity.
The purity of the silicon used in monocrystalline solar panels is a critical factor that influences their efficiency. High-purity silicon minimizes the number of defects and impurities that can trap electrons and reduce the panel’s efficiency.
The results indicate that the degradation rate of mono-crystalline modules is about 0.67% per year. The authors mentioned that degradation and lifetime performance is dependent on the initial photon degradation and material aging.
