Successive rotation approach based novel game puzzles for higher shade dispersion of PV array systems under non-uniform irradiations

Obstructed irradiation negatively impacts solar PV performance and raises issues of power loss (PL). In the partial shading conditions (PSCs), each row in the PV system has a distinct current production capability under the adverse shadowing effects, which is caused to introduce multiple power peaks known as GMPP and LMPP on the power-voltage (P-V) curves. The MPP tracking device is misleading during adverse irradiation circumstances due to numerous power maxima points. The array system adopted a realignment strategy to boost the PV sys-tem's resiliency under the shading mentioned earlier. In this paper, a novel physical relocation approach depends on the 'Successive Rotation Approach' (SRA) based novel game puzzle, which illustrates high GMPP better performance under PSCs. The present study suggests that the SRA puzzle-based PV module restructuring meth-odology has a more significant shade dispersion factor (SDF) capability compared to traditional arrangements such as SP, TCT, SDK, and I-SDK, thus reducing PL and optimizing positions of GMPP. An experimental system is developed to validate the MATLAB/Simulink-based results, which proves the close agreement under similar realistic shading situations. In addition to this, the temperature effect due to shading is ivestigated and non-symmetric (6 x 9) PV array configurations are considered for performance evaluation through experimental work.
