This master's thesis presents a step-by-step methodology for sizing an off-grid photovoltaic
system to supply the Faculty of Science and Technology at Ghardaia University. The study
focuses on using manual calculations to determine the optimal configuration and capacity of the
PV system. The research includes an analysis of solar potential, load power estimation, energy
consumption of the faculty, and the cost estimation. The proposed methodology provides a
systematic approach for designing off-grid photovoltaic system tailored to the specific
requirements of the university. The findings of this study contribute to the field of off-grid solar
system design, particularly in the context of educational institutions
