This article focused on the economic and financial calculations concerning the production of electrical energy from photovoltaic (PV) installations connected to the grid. In this study, the models were proposed for localities of Dori in the North, Ouagadougou in the center, and Bobo-Dioulasso in the South of Burkina Faso. Financial analysis was performed for Dori and Bobo-Dioulasso. The cost of energy produced by PV installations during their operational life span was calculated and compared with other economic parameters. Regression models for estimating global solar radiation on a horizontal surface in these localities were proposed. The results obtained are satisfactory with the coefficient of determination between “0.9745 and 0.9977” and a statistical test t between “0 and 0.09.” The Leveled Cost of Energy (LCOE) of 60 Fcfa/kWh for a discount rate of 4% is almost equal to half the average price of electricity in Burkina Faso, which is equal to 119 Fcfa/kWh.
