A Novel Benzene Structured Array Configuration for Harnessing Maximum Power From PV Array Under Partial Shading Condition With Reduced Number of Cross Ties

IEEE Access, 2022
Partial shading (PS) phenomena significantly degrade the power output from the photovoltaic (PV) array. Due to the PS effect, there is a mismatch in current between the PV modules of a series-connected PV string.

A robust photovoltaic array reconfiguration strategy based on coyote optimization algorithm for enhancing the extracted power under partial shadow condition

Energy Reports, 2021
The operation of photovoltaic (PV) array under shade faces great challenges due to the power loss that reduces the extracted power. Reconfiguration process is one of the most promising solutions to reduce the effect of shadow on the array.
