Determination of the optimal operating distance of a solar PV module under the influence of the electromagnetic field

Résumé fourni par la source

The effect of an electromagnetic field (EMF) on the various electrical parameters of a photovoltaic (PV) solar cell or PV module is not uniform. A high intensity or proximity to an electromagnetic field increases the photoelectric current, while the photovoltage has the opposite effect. Thus, for certain electrical parameters, the EMF can be considered as an external constraint for the operation of a PV solar cell or module. The aim of this work is to determine the optimum operating distance of a PV module exposed to an electromagnetic field. This distance separates the PV solar cell from the source emitting the EMF. The curves and values of the various electrical parameters are analyzed as a function of distance before applying the optimal distance method. A theoretical method is proposed for determining the optimum operating distance of a PV module under an Amplitude Modulation (AM) radio wave field. This method combines the analysis of electrical parameters extracted and calculated from the current-voltage characteristic of the PV module subjected to an EMF, with the use of a color code associated with coefficients. The results show that the optimum operating distance for a polycrystalline silicon PV module subjected to an AM radio wave is 325 m. This value is consistent with that reported in the literature. The proposed method can be used with other external factors affecting PV cell operation.
