Abstract
The PV module configurations are vulnerable to shading effects and cause mismatching power losses. To reduce the detrimental impact of shading and mismatching on energy production, the PV array positioning/reconfiguration is an effective measure. In this research paper sixteen 213 W, 4×4 TCT connected PV array structure has used to analyse the static reconfiguration. This paper emphasises the investigation of the best suitable panel repositioning methodology either within the column (Reconfiguration method 1) or in overall array (Reconfiguration method 2) for static reconfiguration. The MATLAB/ Simulink results have obtained based on P-V characteristics, number of peaks, global maximum power point (GMPP), local maximum power points (LMPP), mismatch losses (ML) and wiring losses (WL). The performance of reconfiguration techniques has analysed under short narrow, long narrow, short wide, long wide, horizontal vertical, diagonal, L-shape, left top corner (LTC), right top corner (RTC), right bottom corner (RBC), left bottom corner (LBC), centre and random shading patterns.
