Impact of the Inverter Sizing in Photovoltaic Systems Considering Solar Irradiance Characteristics

The article analyzes the impact of inverter sizing in photovoltaic systems taking into account the local solar resource behavior. The assessment is performed using real generation data of a photovoltaic system located in the National University of Rafaela, Argentina. The study highlights the importance of considering the local solar resource behavior in order to size more judiciously the inverter. By means of the experimental data, it is possible to provide a well-grounded estimation of the energy not generated due to undersizing the inverter in a photovoltaic system located in Rafaela.
