One of the goals of Oman vision 2040 is to attain a 30 % of renewable energy mix, mainly from solar and wind energy projects for electricity generation by 2030, in alignment with the net zero emissions commitment by 2050. The adoption of residential rooftop solar PV installations supports achieving this target. This paper aims to assess the feasibility and performance of the rooftop solar PV projects at various locations in Oman and to suggest the strategies for promoting rooftop solar PV projects in Oman. In the Middle East countries like Oman, dust from sandstorms and temperature are significantly affects the performance of PV systems and is an important derating factor to consider when evaluating their performance as discussed in this paper. This paper starts by qualitatively assess the suitable regions in Oman for solar PV projects based on temperature levels, dust accumulation, humidity and population density and then proceeds to find the best locations in the selected region. A rooftop solar PV system is designed, analysed its performance, Levelized Cost of Electricity (LCOE) and environmental benefit were calculated for smart bus stop load located in the selected region's university of technology and applied sciences (UTAS) campus using analytical method. The results obtained through analytical method were compared with System Advisor Model (SAM) software. Key findings from the study: The northern part regions of Oman were identified as the most suitable region to install the solar PV systems. In the northern part regions, Ibri is the best location for rooftop solar PV projects compared to other locations. However, at other locations, the AC energy generation from 2.2kWp solar PV systems ranges from 4243.44 kWh to 4841.34 kWh annually, shows that these locations are also competitively suitable for solar PV projects. The LCOE and carbon emission cost of all UTAS branch locations ranges from 8.5 ¢/kWh to 9.7¢/kWh and 128.16 $ per year to 146.74 $ per year accordingly. After finding the most suitable locations and analysis, attractive rooftop policies in solar PV of successful countries are discussed, based on that few strong strategies are suggested to develop rooftop solar PV projects in Oman. The findings from this study will provide the useful guidelines for Oman's energy sector and policymakers to implement and promote roof top solar PV projects in Oman.
《阿曼2040愿景》的目标之一是到2030年实现30%的可再生能源组合，主要来自太阳能和风能发电项目，以符合2050年净零排放的承诺。采用住宅屋顶太阳能光伏装置有助于实现这一目标。本文旨在评估阿曼不同地点屋顶太阳能光伏项目的可行性和性能，并提出促进阿曼屋顶太阳能光伏项目的策略。在阿曼这样的中东国家，沙尘暴带来的沙尘和温度会显著影响光伏系统的性能，正如本文所讨论的，这是评估其性能时需要考虑的一个重要降额因素。本文首先基于温度水平、沙尘积累、湿度和人口密度对阿曼适合太阳能光伏项目的地区进行定性评估，然后在选定区域内找出最佳地点。设计了一个屋顶太阳能光伏系统，分析其性能，使用分析方法计算了位于选定区域理工大学（UTAS）校园内智能公交站负荷的平准化度电成本（LCOE）和环境效益。将通过分析方法获得的结果与系统顾问模型（SAM）软件进行了比较。该研究的主要发现：阿曼北部地区被确定为最适合安装太阳能光伏系统的区域。在北部地区，与其他地点相比，伊卜里是屋顶太阳能光伏项目的最佳地点。然而，在其他地点，2.2千瓦峰值功率的太阳能光伏系统每年的交流发电量在4243.44千瓦时到4841.34千瓦时之间，表明这些地点也具有竞争力，适合太阳能光伏项目。所有UTAS分校地点的LCOE和碳排放成本分别在8.5美分/千瓦时到9.7美分/千瓦时之间以及每年128.16美元到146.74美元之间。在找出最合适的地点并进行分析之后，讨论了成功国家在太阳能光伏方面有吸引力的屋顶政策，并在此基础上提出了一些有力的策略来发展阿曼的屋顶太阳能光伏项目。这项研究的结果将为阿曼能源部门和政策制定者在阿曼实施和推广屋顶太阳能光伏项目提供有用的指导方针。
