Abstract	This study presents the new interconnection scheme for solar photovoltaic (PV) modules to mitigate the power mismatch and wiring line losses employing improvised magic technique (IMT). The proposed interconnection scheme provides improved power enhancement compared to conventional total cross tied (TCT) technique. This technique can be implemented on PV array of any order with ‘x’ rows (x > 2) and ‘y’ columns (y > 2). However, in the higher order PV modules, power mismatch loss and wiring loss reduced significantly using segmented improvised magic technique (SIMT). The sequence of reconfiguring the PV modules has been explained using a flowchart and an algorithm both for IMT and SIMT. The effectiveness of these techniques is tested using MATLAB simulations and validated the analysis by comparing the performances with the existing TCT for lower order (3 × 3) with experimentation and higher order (9 × 9) PV modules. Thus, the proposed IMT and SIMT techniques provide the maximum power enhancement, less power mismatch and line loss, and maximum improved efficiency in real-time PV array installations.
