Management of Duhok Governorate Environment by Generating Sustainable Solutions (Rooftop Photovoltaic Systems) In Buildings Instead of Regular Electricity: Environment, Management and Techno-Economic Evaluations

Population growth and increasing demand for energy have been causing severe environmental problems all over the world. This research is done to find a suitable management way to improve the environmental condition, develop sustainable and economical solutions. This study focused on using Rooftop Photovoltaic Systems for the first time in Duhok governorate, Iraq, due to the rapid growth in the governorate and the great demand for energy, and the high energy production costs. Four regions were chosen in Duhok governorate to install photovoltaic systems. The NASA database as a source for assessing solar energy potential were used. The results show that these areas have enormous potential and annual solar radiation to produce solar energy. The RETScreen expert evaluated the electricity production potential of PV systems. In addition, an economic study of 5kW capacity for grid-Connected rooftop PV projects was carried out in all selected regions. Depending on the financial results and indicators, Rooftop Photovoltaic Systems can be a sustainable and efficient solution to improve the environment and economically installable in the Duhok governorate.
