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.

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.

A Ku-Band Low-Loss Traveling-Wave Power Divider using a Hollow Substrate Integrated Waveguide and Its Microstrip Transition [PDF]
Journal of Electromagnetic Engineering and Science, 2020 In this paper, we present a Ku-band low-loss traveling-wave power divider that uses a hollow substrate integrated waveguide (HSIW). For easy connection with microstrip-based devices and circuits, a low-loss transition between the microstrip line and the ...
