Comparative Performance Evaluation of PV Configurations Under Various Shaded Conditions

Abstract

Partial shading is a common issue that occurs in building roof-top PV arrays. This condition generally occurs due to the shadows of the buildings and clouds around them. In most cases, partial shading causes mismatched losses in the solar PV system. This issue usually affects the power output of the healthy modules. Hence in this paper simulation and modeling approach for solar PV system setups with varying shading scenarios. The results show that the performance of various configurations of the system under different shaded conditions. A 200 W 5×5 size PV panels are considered as test case. A comparison analysis is then carried out for the various parameter of the solar PV system, such as the Fill Factor FF (%), PV Mismatch losses Pml (%), Efficiency ή (%), Maximum Power Pmp (W). Detailed comparison charts are presented. In the all the above parameters TCT shows the best performance next to TT configuration.
