Abstract: The electrical power generation from solar photo voltaic arrays increases by reducing partial shading effect due to the deposition of dust in modules, shadow of nearby buildings, cloud coverage leads to mismatching power losses. This paper gives the detailed analysis of modeling, simulation and performance analysis of different 4×4 size PV array topologies under different irradiance levels and to extract output power of panels maximum by reducing the mismatching power losses. For this analysis, a comparative study of six PV array topologies are Series, Parallel, Series-Parallel, Total-Cross-Tied, Bridge Linked and Honey-Comb are considered under various shading conditions such as one module shading, one string shading, zig zag type partial shading and total PV array partially shaded cases. The performance of above six topologies are compare with mismatching power losses and fill-factor. For designing and simulation of different PV array configurations/topologies in MaTLab/Simulink, the LG Electronics LG215P1W PV module parameters are used in all PV modules.
