CONTRIBUTION TO THE ASSESSMENT OF METEOROLOGICAL PARAMETERS (SOLAR RADIATION, TEMPERATURE, AND HUMIDITY) AT THE MAMOU HIGHER INSTITUTE OF TECHNOLOGY SITE FOR OPTIMAL EXPLOITATION OF SOLAR POTENTIAL

Abstract

Accurate assessment of incident solar energy at a given site is a key factor in evaluating the profitability of any photovoltaic project. Acquiring data on solar potential remains difficult. Such data is obtained through direct measurements, calculations based on empirical formulas, or satellite data. The main objective of this study is to assess the solar potential of the Mamou Higher Institute of Technology site through direct in situ measurements of irradiation, temperature, and air humidity using a mini station during the period from May 26 to November 22, 2025. In this study, we used information on radiation, air temperature, and humidity recorded at the mini station of the Mamou Higher Institute of Technology. In the data analysis phase, we set the production threshold at 50W/m² and found: a maximum monthly average of 206.14 W/m² in October compared to a minimum of 157.29W/m² in July for irradiation and corresponding temperature and humidity values, standard deviations and correlation coefficients and their interpretations. The cumulative number of hours of sunshine during the study period was 1,770.25 hours, with a daily average of 9.73 hours. Excel and Python software were used for pre-processing, processing, analysis, and graphical representation of the information, respectively. The daily and monthly averages were 1090 W/m² and 179.18 W/m² for irradiation, 26.31 °C and 23.33 °C for temperature, and 97.78% and 99.59% for humidity, respectively. Irradiation had a high standard deviation (283.60); low values for temperature (4.421) and 1.587 for humidity. The remarkable values of the correlation matrix (0.224 and -0.275) indicate low dependencies between temperature and radiation on the one hand and negative correlations between humidity and radiation on the other. The results obtained show a dispersion of irradiation values and little variation in humidity, reflecting remarkable variability in sunshine during the day and a generally stable climate
