Nahhas amnahhas@uqu.edu.sa 1 Department of Electrical Engineering, Umm Al Qura University, Makkah, Saudi Arabia The Saudi Arabia intends to promote solar power generation as a discipline in most of the country's universities, as well as large solar projects and renewable energy in general. To achieve solar energy goals, the academic community of engineers and professors is now conducting a variety of facilities, research projects and analytical studies for all regions of the country to provide clean energy in the future. As a result, the country's latest solar improvements are undergoing a period of development for scientific research and analytical studies. This paper is presenting the study of the means to facilitate the work of projects in the field of solar energy, which is to complete the calculation of the total cost of both stations based on our previously published study. The (PVsyst 7.1) simulation software is used to simulate the installation of photovoltaic cells on Saudi Arabia different regions including as the eastern western coast and the center region. Also, the tracker system may be used to track the sun and create more electricity from PV systems. https://pubs.sciepub.com/ajer/12/1/2/ajer-12-1-2.pdf PV solar cells renewable
