Abstract
This paper proposes an improved permanent structuring technique to configure the panels in photo voltaic (PV) array so that optimum power output can be achieved under partial shading conditions. The proposed technique enables the structure to redistribute shading effect on complete PV array by using panel physical positions alternatively. The PV modules are connected in TCT configuration and this TCT configured array is structured based on ODD-EVEN pattern. The ODD-EVEN structures of panels don’t change electrical connections of TCT connected PV array. The rendition of proposed structure of PV array is investigated under various shading conditions. The proposed technique has resulted in an appreciably improved power generation of PV array at output terminals. The technique mitigates occurrence of multiple local maxima and thus avoids the necessity of complex maximum power point tracking algorithm. The simple and cost-effective PV array structure is the additional merit associated with this configuration.
