Estimation of ultraviolet solar irradiation of semi-arid area - case of Benguerir-

Any change in solar sources due to climate raises some of the issues related to the stability of the electrical system produced by photovoltaïque (PV), to start studies to predict all changes in solar radiation to have a more reliable electrical system. In this work, we focus on the estimation of the ultraviolet (UV) part of the solar spectrum because it considers it as a source of aging of the Ethylene-Vinyl Acetate (EVA) encapsulation layer. To achieve this objective, an Artificial Neural Networks (ANN) used with two inputs: the global horizontal irradiation (GHI) and the Solar Zenithal Angle (sza), which are easy to find for any work site.
