ABSTRACT: The Grid-Connected solar PV (GCPV) system mounted on residential and commercial buildings are likely to become a small but important source of electricity generation in the next century. Because most of the power supply in the country is via centralized electric grid. This is new concept in utility power production, a change from large scale examination of many existing standards and practices to enable the technology to develop and emerge into the marketplace. This paper gives design idea of optimized grid connected solar PV plant proposed at Habibganj. Using actual data for both loads and irradiance is used for simulation of grid connected PV, done with the use of computer software package PVsyst 5.53. I
