Design and Realization of a Mini Station for Measuring Solar Irradiation, Temperature and Humidity at the Higher Institute of Technology (IST) Mamou

In this work, we designed, built and tested a mini station for measuring solar irradiation, temperature and air humidity at the Higher Institute of Technology (IST), Mamou. For this purpose, we designed a device far from any shading, consisting a 2m in three-piece of mast topped by a squaresh tube bar to which the pyranometer, temperature and humidity sensor are attached, a metal box serving as a shelter for the irradiation and temperature dataloggers, the photovoltaic system equipment and a 20Wp solar panel to supply the system with energy. A grounding device protected the entire system. After parameterization and direct measurements during the test period from August 12 to 20, 2024, seven hundred and forty-two (742) lines of data were recorded and plotted for analysis. The following results were obtained: A coverage rate of 100% and around 75h of sunshine. However, the days 13, 14, 16, 19 and 20 were very sunny, with a maximum value of 1224W/m², a minimum of 1W/m² and an average of 142W/m². Minimum and maximum temperatures were 18°C and 31.7°C respectively, with an average of 11.17°C. For humidity, the maximum (99.9%) was recorded almost every morning and evening during the same period, the minimum 7.4% (August 15 at 3:48 P.M) with an average of 95.34%.
