Today, with economic and mass production of solar cells or photovoltaic (PV) system, the use of solar energy has been highly regarded to supply the energy needs of buildings and their independence and even sales the excess of that needed to power companies.
In this study the feasibility of using a photovoltaic system to supply the electrical charge required for a residential unit in Mashhad city, has been investigated. For this purpose, technical - economic analysis of the use of this system has been analyzed using the COMFAR Software.
