The installation of a photovoltaic system is becoming increasingly attractive to consumers in residential areas due to higher electricity tariff rates and less dependence on local power generators in Iraq. Consequently, the paper's main objective is to determine the applicability of solar photovoltaic (PV) systems in the capital city (Baghdad) of Iraq. Additionally, this study aims to find suitable PV technology and sun-tracking system for building applications in Iraq. To obtain this aim, the PVGIS simulation tool is used. It has been found that the selected city is suitable for installing PV systems in the future because of the high value of solar radiation. Furthermore, the results indicated that CdTe technology has the highest performance compared to the crystalline and CIS PV technologies. Moreover, it is observed the two-axis system has the maximum energy generation compared to vertical and include systems. This study provides useful details regarding installing a PV system in Iraq to solve the electricity crisis in the country and reduce fossil fuel consumption.
