The aim of this work is to determine the possibility of producing electrical energy based on solar radiation in the city of Tripoli- Libya. The solar radiation data were taken from the NASA POWER platform. The results indicate that there is a high possibility of producing electrical energy during most months of the year, especially during the summer season. Where the highest value is reached in June 2022, and the lowest value is reached in December 2017. For the electrical capacity of solar cells, the highest value is reached in July 2022, and the lowest value is reached in December 2017. This type of research is an essential step in planning renewable energy projects................. Keywords: ...........electrical energy, solar radiation, electrical capacity, Tripoli.
