Over the past decade, there has been significant growth in power demand in Saudi Arabia. This has been due to various factors, including population increase, economic development, advancements in living standards, severe weather conditions, industrial growth, energy use policies, energy source diversification and low pricing energy regimes. It is necessary to use renewable energy sources as one of the solutions to cover and reduce that demand, which is particularly high in the residential sector. The use of solar power systems, such as building-integrated photovoltaic (BIPV) systems, in residential roofs is the fastest and simplest solution. Solar energy utilization could be one of the solutions to generate alternative energy in ways appropriate for the geographical location and other aspects of Saudi Arabia. This study will indicate the impact of this approach, which will have many advantages in supporting residential energy use. This study finds that Saudi Arabia is undoubtedly one of the countries in the world that needs to produce a combination of energy which balances oil production and sales and reduces domestic consumption. Such a balance must also provide sufficient energy to meet the targets of the Saudi economy, especially since most areas of Saudi Arabia are characterized by a very high-temperature tropical climate in the summer.
