Nahhas amnahhas@uqu.edu.sa 2 Department of Engineering Affairs, General Directorate of Civil Defense, Jeddah, Saudi Arabia Department of Electrical Engineering, Umm Al Qura University, Makkah, Saudi Arabia This paper presents an analytical study of photovoltaic (PV) power generation of two regions in Saudi Arabia. Renewable energy resources have recently been acknowledged as a vital component of global economic stability, particularly in countries like Saudi Arabia. Saudi Arabia is a vibrant country that is experiencing significant population increase, which has resulted in high electricity usage. Because of the strong solar radiation, huge rainless area, and lengthy sunlight, Saudi Arabia has a bright future in terms of using solar energy more broadly. As a result, the Saudi Arabian government has invested billions of dollars in large-scale renewable and sustainable energy projects around the country, backed by strong funding. Saudi Arabia wants to boost solar power output to meet a large amount of the country's prospective energy needs. Various installations and research projects are currently being carried out throughout the kingdom to meet its solar power ambitions. As a result, it is critical to keep up with the latest developments in the solar business in the country. Development and Research (R&D). In this work a simulation (PVsyst 7.1) software program to simulate the installation of PV cells on two regions of Saudi Arabia including Al-Al-Riyadh and Al-Jubail regions. Also, the possibility of using the tracker system to track the sunshine and generate more power from PV systems is discussed. This paper presents, however, is a partnership and it intends to examine the existing state, growth, potential, resources, sustainability performance, and prospects of renewable energy in Saudi Arabia in accordance with Saudi Vision 2030. http://pubs.sciepub.com/ajer/9/1/5/ajer-9-1-5.pdf PV solar cells renewable Saudi Arabia
