<title>Abstract</title> <p>As climate change continues to raise concerns globally, increasing energy costs and increasing demand for renewable energy sources have increased both the amount of research and the quantity of research spent on renewable energy technologies. Due to its extensive availability throughout Ethiopia's Afar region, solar energy has emerged as the most promising renewable energy option. This study aimed to investigate the solar resources in the Afar region by analysing ground-based meteorological data gathered from Assiyta, Dubti, and Samara. The amount of solar radiation at each place was estimated using the Angstrom–Prescott equation and sunshine duration data. The amount of irradiance was mapped, and seasonal changes were identified using statistical methods based on Geographic Information Systems (GIS). The average daily solar irradiation was found to be 6.7 kWh/m² in Samara, 6.1 kWh/m² in Dubti, and 6.3 kWh/m² in Assiyta. The average daily amount of solar irradiance for the three locations will be valuable to local organizations looking to install solar energy. This work will also assist with electrification efforts for pastoralist communities, as well as assist governments with developing policies that will encourage the sustainable use of renewable energy in the Afar region in the future.</p>
