This work presents the technical-economic analysis and the environmental realization of a solar photovoltaic micro-grid capable of supplying the load of a household in three cities of Tunisia, which was chosen as a case study. Firstly choosing the components of our system taking into account the economic variables using HOMER software. A comparative study is carried out for four system configurations in the three selected cities to give that the optimal system is: PV-GRID. The results of the optimal system simulation gave us the following results for the three cities (Bizerte, \mathbf{NPC=3.942} MDT, \mathbf{COE=0.0300}\mathbf{DT}/\mathbf{KWH, CO_{2}=1.173} Kg/year, \mathbf{Ren=75.6 \%} , (AI-Rudayyif, \mathbf{NPC=4.232} MDT, \mathbf{COE=0.0327} DT /KWH, \mathbf{CO_{2}=1.205} Kg/year, \mathbf{Ren=75.6 \%)} and (Remada, \mathbf{NPC=3.601} MDT, \mathbf{COE=0.0276} DT /KWH, \mathbf{CO_{2}=1.159} Kg/year, \mathbf{Ren=77.5} %) on the other hand the use of grid only gives us \mathbf{(NPC=11.956} MDT, \mathbf{COE=0.176} DT/KWH, \mathbf{CO_{2}=2.597} Kg/year). This analysis has proved that the implementation of this project type can produce continuous electricity production in Tunisia as well as clean and economical solutions.
