Performance Analysis of 4.68 kWh Proposed Grid-Connected PV System in Iraq

Iraq is one of the countries that have solar energy over the year. However, the PV solar systems have not received sufficient support from the Iraqi government. Also, the on-grid PV solar systems have not been used to feed the transmission lines of national electricity. Therefore, in this study, a dynamic simulation with 3D visualization (PV*sol premium valentine) software was used to analyze and calculate the characteristics output of the system according to the weather data of Iraq capital city – Baghdad (latitude 34.03
^o
and longitude 45.04
^o
) for one year. The size of the proposed system was 4.68 kWh and consists of 18 Polycrystalline silicon cell modules with a total area of 30.2 m
²
and inclined at an angle of 27
^o
. The performance analysis of the system includes total production, efficiencies, performance ratio (PR), capacity utilization factor (CUF), yield types, and energy losses. The total energy generated during this period was found to be 7336 kWh/year. The annual mean of PV module, PV system, and inverter efficiencies was found to be 13.78%, 12.98%, and 82.48% respectively. While the PR and CUF were found to be 81.19% and 17.84 respectively. On the other side, the annual mean of final yield, total losses, and losses in the inverter was found to be 4.28 h/d, 0.88 h/d, and 9.24% respectively. Some of the important performance parameters of PV systems were compared with the performance of convergent systems in size available in the literature.
