Abstract: Partial shading in PV panels occur due to passing of clouds, shadows of tree, building and poles which in turn greatly reduces the power output. In the proposed work, the solar PV modules are rearranged using a novel reconfiguration topology resulting in the effective distribution of the shadowing effect over the entire PV array without modifying the electrical connections. This proposed reconfiguration topology is so versatile that it can be extended for any number of PV modules. The system performances are investigated for different shadowing pattern and the results obtained using the intelligent reconfiguring technique yields improved performance compared with Su Do Ku configuration.
