On-Grid Mono-Si PV Solar System Performance Evaluation in Baghdad

Abstract

Abstract The performance assessment of a 5 kWp On-Grid Mon-crystalline silicon photovoltaic( PV) solar system is the subject of the present paper. This PV system is located in Baghdad city, Al-Mansour company. The present PV solar system is observed during 2018. The current system’s yearly daily averages for the array yield final yield, and the reference yield are 4.65 kWh/kWp, 4.5 kWh/kWp, and 5.9 kWh/kWp, respectively. The final yield’s yearly energy is 1613.8 kWh/kWp. The present year’s electrical energy output from this system is 7891.57 kWh, and Baghdad’s annual global horizontal solar irradiation (GHI) is 1987.5 kWh/m2. The average yearly daily losses for the system and the array are 0.15 kWh/kWp and 1.33 kWh/kWp, respectively. The average yearly efficiencies for the system, the array and the inverter are 11.33%, 11.7%, and 96.75%, respectively. The annual daily averages for performance ratio and capacity factor are 74.7% and 17.75 %, respectively. Mono-crystalline silicon (Mono-Si) seems to operate well in the environment of Baghdad-Iraq.
