This work consists of studying the types of existing photovoltaic installations, those connected to the grid and those not connected to the grid, better known as on-grid and off-grid installations. The study will be done at the level of the equipment, the production of energy specific to the installation and the metrological forecasts of the chosen area and the technical and economic balance sheet of the two installations, we will also touch on the different aspects and basic stages of the sizing of these installations in order to better distinguish the various components of these systems..At the end we will give a general conclusion which will touch on a comparison between the advantages and disadvantages of the two types of installation.
