Performance Comparison of Mismatch Power Loss Minimization Techniques in Series-Parallel PV Array Configurations [PDF]
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).

Power coupling losses for misaligned and mode-mismatched higher-order Hermite–Gauss modes [PDF]
Optics Letters, 2021 This paper analytically and numerically investigates misalignment and mode-mismatch-induced power coupling coefficients and losses as a function of Hermite–Gauss (HG) mode order. We show that higher-order HG modes are more susceptible to beam perturbations when, for example, coupling into optical cavities: the misalignment and mode-mismatch-induced ...

Investigation of Power losses on Solar Photovoltaic Array Interconnections Under Mismatch Conditions [PDF]
Technology and Economics of Smart Grids and Sustainable Energy, 2021 The mismatch effect creates a difference between the sum of maximum power generated by individual Photovoltaic (PV) modules and the overall PV array power output. Mismatch effects can be classified into internal and external mismatch effects. Internal mismatch effect occurs because of factors such as manufacturing defects and ageing.
