Solar energy is considered one of the most important alternative renewable energy sources, which has witnessed significant development globally in recent years. It is less expensive, more efficient, and more sustainable, meeting part of the existing demand and reducing pollution. The aim of this research is to calculate the amount of energy that can be produced from solar radiation. The electrical capacity of solar cells, as well as the efficiency of converting solar energy into electrical energy, was calculated through monthly and seasonal analysis of solar radiation, where the highest and lowest values were calculated over the months of the year. One of the most important results obtained from this study is the clear variation in the potential solar electrical energy production, where the maximum value is reached in the summer months, while it decreases significantly in the winter months due to the distance of the sun along the Tropic of Capricorn, which is far from the study site and the low intensity of solar radiation during those months. The maximum value of the calculated electrical capacity reached 5288.5 watts per square meter in August due to the sun's direct sunlight during this month, while its lowest value was reached in January, at 5009 watts per square meter. The potential electrical capacity from solar radiation also varies significantly seasonally, with summer having the highest values of all years .............
