Parameter Enhancement of Solar Array under Partial Shading conditions

Abstract

Partial shading is the major drawback of reducing the output power of PV array. Shade dispersion through Tom-Tom puzzle pattern is proposed in this manuscript to reduce the partial shading effects. The proposed method is compared with standard TCT configuration to test its efficacy. 25 panels arranged in 5 × 5 array is considered for the study to test the standard and proposed techniques under the progressive increment of shading patterns. The results demonstrate that the reconfiguration through Tom-Tom configuration yields better performance parameters than the conventional configuration.
