The generated power from Photovoltaic Power System, PVPS have been calculated by a computer program under known insolation and temperature. The computer program, which proposed here and applied to make optimal design of PVPS, is based on the minimization of the energy purchase from grid. This paper presents a complete study from economic and reliability point of view to determine the impact of interconnecting PVPS with electric utility, EU taking into consideration battery storage, BS, all radiation and variation of the load demand during the day. Three different configurations of PVPS have been investigated. The first PVPS is stand-alone PVPS accompanied with BS. The second PVPS is PVPS interconnected with EU without BS. Grid-connected PVPS accompanied with BS represents the third alternative. A comparative study between these three different configurations has been carried out from economic and reliability points of view with the main goal of selecting suitable one, to be installed at Zafara¿na site to feed the load requirement. A simulation is carried out over one year using the hourly data of the load demand, insolation and temperature at Zafara¿na site, Egypt as a case study.
