Mitigation of mismatch power loss in aged photovoltaic arrays following a comparative investigation into module rearrangement techniques

Energy Reports, 2022
Power degradation due to non-uniform aging is a common phenomenon in large photovoltaic array systems. Aging increases the current–voltage mismatch in the array modules that results in mismatch power loss in the array.
