Performance Comparison of Mismatch Power Loss Minimization Techniques in Series-Parallel PV Array Configurations

Energies, 2019
The mismatch in current-voltage (I-V) characteristics of photovoltaic (PV) modules causes significant power loss in a large PV array, which is known as mismatch power loss (MML).
