Suppression of Output Power Decrease During Partial Shading by Parallel Cell Cluster Type PV Modules

This paper proposes the "Parallel cell cluster method" as a PV module-level solution to the problem of output power decrease caused by partial shading of the PV array in a PV power generation system.This method is new method previously proposed by the authors to reduce hot spot heating caused by crystal defects in PV cells.This paper investigates the effectiveness of this method in suppressing output power decrease during partial shading.The results of the study revealed that this method is effective in suppressing output power decrease during partial shading.
