Energy Acquisition of Solar-Powered Joint-Wing Aircraft Considering Mismatch Power Loss [PDF]
Energies, 2021 Solar-powered aircraft can perform long-term flights with clean solar energy. However, the energy derived from solar irradiation is influenced by the time of year and latitude, which limits the energy acquisition ability of solar aircraft with a straight-

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).

Estimating and parameterizing mismatch power loss in bifacial photovoltaic systems
Progress in Photovoltaics: Research and Applications, 2020 AbstractNonuniform irradiance on the rear side of bifacial photovoltaic (PV) systems can cause additional mismatch loss, which may not be appropriately captured in PV energy production estimates and software. We evaluated several scenarios including horizontal single‐axis tracking (HSAT) over natural ground‐cover and rooftop‐mounted systems over high ...

Mitigation of power mismatch losses and wiring line losses of partially shaded solar PV array using improvised magic technique [PDF]
IET Renewable Power Generation, 2019 This study presents the new interconnection scheme for solar photovoltaic (PV) modules to mitigate the power mismatch and wiring line losses employing improvised magic technique (IMT). The proposed interconnection scheme provides improved power enhancement compared to conventional total cross tied (TCT) technique.

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 ...
