Benefit from solar radiation as an alternative energy in the city of Riyadh

The vision of the Kingdom of Saudi Arabia 2030 indicates that the Kingdom enjoys natural elements in the field of solar energy. The objective of the study is to know the characteristics of solar radiation distribution in Riyadh city, how to convert solar energy into electrical energy, power generation projects in Riyadh and the problems facing solar energy production in Riyadh.
The requirements of solar radiation for electricity generation were determined by studying the amount of solar radiation falling on the unit area over a specified period of time as well as the number of hours of solar brightness. Riyadh is located within a high range of solar intensity throughout the year, Where the average annual solar radiation in the city of Riyadh reaches (418) calories / cm 2 / day. The height of the space is due to its astronomical position close to the orbit of cancer (23.5 North) to the sun's rays in the summer, and the sky of the region most of the year except for a short period in winter and spring, and the length of the day and the subsequent increase in the number of hours of brightness, 8.1) hours encourage the production of clean electric power. The monthly, quarterly and annual averages of solar radiation and the number of hours of brightness in Riyadh were calculated, the possibility of estimating solar radiation at different locations, and the presentation of solar and power generation projects in Riyadh. The study recommends expanding studies on solar cells and solar towers, and encouraging the private sector in the province to invest in this field as promising.
