In this article, a technical-economic study has been displayed to evaluate the productivity of grid-connected photovoltaic (PV) solar system in a campus of University of Zakho, Iraq. The feasibility of this study is based on performance ratio, capacity factor, cost of energy and yield factor. The analysis of the system has been performed using System Advisor Model (SAM) software and real data of Zakho city that is available in national renewable energy laboratory (NREL). Results show that the system produces 5205 AC MWh during the year with a maximum power generated by the arrays equal to 3.15 AC MW. The yield factor from the proposed PV system for first year is 1554 kWh/kW, whereas the capacity factor nearly equal to 17.7%. Findings indicate that the cost of energy generated by the solar system is 6.3¢/kWh. The payback period to restore the cost of the government electrical energy without using the local electrical generators is 7 years while the payback period becomes 4 years when local electrical generators is used. Finally, results demonstrate that the investment in the technology of PV system is quite favourable in this site and hence, this article has a valuable information for those who wish to invest in PV technology in Iraq.
本文展示了一项技术经济研究，以评估伊拉克扎胡大学校园内联网光伏 (PV) 太阳能系统的生产力。这项研究的可行性基于性能比、容量系数、能源成本和产量系数。该系统的分析是使用 System Advisor Model (SAM) 软件和国家可再生能源实验室 (NREL) 提供的扎胡市的实际数据进行的。结果表明，该系统在一年内可产生 5205 兆瓦时交流电，阵列产生的最大功率等于 3.15 兆瓦交流电。拟议的 PV 系统第一年的产量系数为 1554 千瓦时/千瓦，而容量系数接近 17.7%。研究结果表明，太阳能系统产生的能源成本为 6.3 美分/千瓦时。如果不使用当地发电机，恢复政府电力能源成本的投资回收期为 7 年，而当使用当地发电机时，投资回收期为 4 年。最后，结果表明，在该地点投资 PV 系统技术非常有利，因此，本文为那些希望在伊拉克投资 PV 技术的人提供了有价值的信息。
