Sizing Of Photovoltaic Standalone System In Mandali City / Iraq: A Case Study

Abstract

This paper includes a study on the load requirements of houses located in Mandali city, Iraq, as well as design and installation of a stand-alone photovoltaic (PV) system. The utilization of PVsyst simulation software has facilitated the examination of performance ratio with losses. The mean annual energy demand within the residential dwelling is recorded as 4 614,5 kilowatt-hours per year, while the solar panel system is capable of generating 5 731,6 kilowatt-hours per year. However, the energy delivered to the user falls slightly short of the required load, amounting to 4 614,5 kilowatt-hours per year. The diminished power capacity for the system can be attributed to many types of losses. The examination of performance ratios indicates that the month of November exhibited the highest performance ratio (PR) at 87,57 %, while the lowest PR of 50,61 % was seen in April. On average, the PR for the entire year was calculated to be 63 %. The diminished power capacity for the system can be attributed to many types of losse
