Abstract: In solar photovoltaic (PV), the existence of partial shading and faults deteriorates the overall performance. Many reconfiguration techniques are used to curtail mismatch losses. The main shortcomings of the PV reconfiguration are the detection of faults and partial shading. Most of the reconfiguration techniques extract less power from PV arrays due to the above shortcomings. This paper proposes a novel PV configuration with a battery connected across the rows of each Total Cross Tied (TCT) array. This technique eradicates the necessity of reconfiguration in PV array. A 3 × 3 TCT PV array, which consists of 9 modules with a 10 W rating. The effectiveness of the proposed method has been tested in the MATLAB Simulink environment. The analysis is carried out in terms of output power and performance parameters. The experimental results were also taken and it is validated with Simulink. Additionally, a comparative study was conducted on the various existing methods presented in the literature. From the results, it is evidenced that the proposed configuration enhances the output power of PV by 39.46%. The study results show the significance of the proposed method. This study would be significantly useful for the researchers in mitigating the fault and partial shading effects.
