Abstract
The sun is considered one of the largest environmentally eco-friendly and sustainable energy sources, and Iraq ranks among the countries with substantial natural wealth .Iraqi population have recently suffered from the high number of hours of electrical power outage for the local and government sectors this depends on fossil fuels, as Iraq imports most of the liquid gas used for this purpose, and from this point of view, it is necessary to search for energy sources that support the supply of electrical energy and compensate for the shortage in the hours of processing of electric current. In the present research project. The solar photovoltaic system was connected on the rooftop of structure in Baghdad. A comprehensive performance assessment of this on-grid system is carry out under the local climatic conditions of Baghdad. Over the monitoring period, the system achieved an annual energy output of 166.893kWh. The daily array yield, final yield and reference yield were determined to be 4.72 kWh/kWh, 4.23 kWh/kWh, and 5.58 kWh/kWh, respectively, indicating the systems operational efficiency under real-world conditions. The results further revealed that annual average regular total losses, array fatalities and system losses are 1.35 kWh/kW, 1.12 kWh/kWh, and 0.23 kWh/kWh, additionally, the yearly efficiencies of the inverter, the overall systems, and array were found to be 98.38%, 75.91% and 20.98%. The presentation ratio and average capacity issue were 17.6% and 75.91%.
