ELECTRICAL PERFORMANCE DEGRADATION ANALYSIS OF FIELD EXPOSED SILICON-BASED PV MODULES

Degradation of on-field PV modules is inevitable but a normal process; however, it challenging task to explore the causes behind it. Manufacturers and researchers, know degradation, employ both destructive non-destructive procedures. In this study, nine different from three manufacturers have been taken their electrical output data, over several days, has collected. The parameters are compared with nameplate data analyze average yearly degradation in performance. Moreover, using visual inspection modes identified. Finally, concluded that environment not only factor material used processing techniques employed by equally responsible for efficiency modules.
