2.2.1. Monitored Data

The first data source used in this research is the measurement acquisition work carried out in [23] regarding the same PV system that is modelled on the present study. Said installation is monitored by means of two types of sensors for weather variables: an irradiance sensor LP-PYRA02 to measure the hourly mean solar irradiance on the two inclined surfaces (3◦ and 15◦), and a PT100 temperature sensor to gauge the hourly mean air temperature and the temperature of the PV modules. Hourly mean photovoltaic power data for the entire installation is extracted from three inverters. The air temperature, the two solar irradiations, and the output power compose the monitoring dataset, the first of two used in the present study.
