Introducing a PV Design Program Compatible with Iraq Conditions

Abstract Solar energy is rapidly gaining the focus as an important means of expanding renewable energy uses. Different Programs have been used in Photovoltaic (PV) Design but all of them have the design parameters fixed cannot be changed, also the devices that the programs offer cannot be changed and most of them are not available in Iraq. This paper presents a programming of Off-Grid Photovoltaic System Design Software (PVSD) using Visual Basic to work with Iraq Condition; also this program will contain all the PV modules, Battery, Inverter and Charge Controller which are available in the market with their detail. This PV design program will have all the electrical calculation you need to design and select the components of PV system with their price and all the print out will be ready as a full report about the system designed. This program draw the electrical design of the system designed as it will contain the actual parameters for Iraq Conditions. A project has been designed using this program and has been implemented in Ministry of Science and Technology and it's working with the same results. The experimental results have been compared with the theoretical results and it shows the accuracy of this program.
