沙特阿拉伯王国（KSA）拥有大量的太阳能和风能资源。通过开发此类资源的“2030年愿景”，KSA计划到2030年通过太阳能和风能的组合安装9.5 GW的可再生能源发电系统。政府计划在未来20年内投资1090亿美元用于太阳能。重点将放在国家一级的太阳能光伏和聚光太阳能技术上。到目前为止，KSA的电力需求几乎完全依赖化石燃料发电。本文探讨了在不同规模上利用太阳辐射资源的潜力，并减少了电网的电力需求，为住户和政府带来了附带利益。这项工作提出了两个典型的国内建筑物（别墅）在吉达，KSA监测的用电量的结果。耗电量的观察与室内环境条件相关联，以研究制冷需求如何以及何时影响最终需求。该研究调查了通过安装在两栋建筑物屋顶上的光伏电池板阵列模拟发电来满足别墅需求的方案。最后，建立了动态太阳辐射模拟模型，评估了每小时发电量，并对不同容量的光伏系统方案进行了成本效益分析。结果表明，当地使用的屋顶光伏输出可以减少约80%的家庭电网电力需求，在住房水平，并结合建筑物翻新解决方案，可以导致额外的节能。经济分析讨论了建议的上网电价与相关的投资回收期和投资回报率的影响，以及在KSA建筑物屋顶大规模部署光伏系统的建议。
The Kingdom of Saudi Arabia (KSA) has a large solar and wind energy resource. Through its Vision 2030 to exploit such resources, KSA is planning to install 9.5 GW of renewable energy power generation systems by 2030, through a mix of solar and wind energy. The government is planning to invest 109 billion US$ over the next 20 years for solar energy. The focus will be on solar photovoltaic (PV) and concentrated solar technologies at a national level. So far, the electricity demand in KSA is almost entirely dependent on fossil fuels for generating power. This paper addresses the potential to utilize the solar radiation resource at a different scale and reduce the power demand from the grid, bringing collateral benefits for householders and the government alike. The work presents the results from monitoring the electricity consumption of two typical domestic buildings (villas) in Jeddah, KSA. The electricity consumption observations were associated with indoor environmental conditions to study how and when cooling demand affects final demand. The study investigated options to serve the observed demand profile of the villas with simulated power generation from arrays of PV panels installed on two buildings’ roofs. Finally, a model of dynamic solar radiation simulation was developed to assess the hourly electricity generation, and a cost-benefit analysis was conducted for different capacity PV systems scenarios. The results indicate that locally used rooftop PV output could reduce the household electrical demand from the grid by around 80% at the housing level and in combination with building refurbishment solutions, could result in additional energy savings. The economic analysis discusses the implications of a proposed feed-in tariff with the associated payback periods and ROI, as well as proposals for PV system deployment at a large scale on the roof of buildings in KSA.
