Abstract
Countries with limited natural resources and high energy prices, such as Jordan, face significant challenges concerning energy consumption and energy efficiency, particularly in the context of climate change. Residential buildings are the most energy-consuming sector in Jordan. Photovoltaic (PV) systems on the rooftops of residential buildings can solve the problem of increasing electricity demands and address the need for more sustainable energy systems. This study calculated the potential electricity production from PV systems installed on the available rooftops of residential buildings and compared this production with current and future electricity consumption for residential households. A simulation tool using PV*SOL 2021 was used to estimate electricity production and a comparative method was used to compare electricity production and consumption. The results indicated that electricity production from PV systems installed on single houses and villas can cover, depending on the tilt angle and location of the properties, three to eight times their estimated future and current electricity use. PV installation on apartment buildings can cover 0.65 to 1.3 times their future and current electricity use. The surplus electricity produced can be used to mitigate urban energy demands and achieve energy sustainability.

Summary
Energy has been crucial to the demographic, social and economic development of human society [1,2,3,4,5]. Installing PV systems on the rooftops of residential buildings can provide a mitigation strategy for the increase in future energy consumption and may play a crucial role in the development of clean and sustainable energy sources [11]. It has become necessary for Jordan to find renewable energy sources as an alternative to the costly energy imported from abroad The best of these alternatives is solar energy, which is considered the most successful in terms of investment. PV technology is essential to achieve a significant increase for the use of renewable solar energy sources for achieving the sustainable development goals [28,29], because. PV rooftop systems can significantly reduce greenhouse gas (GHG) emissions from the residential electrical sector, as renewable energy sources are producing less emissions [31]. 14% and street lighting at 2% [17,38,39,40,41]
