solar energy

It is considered one of the most prominent and most important modern sources through which energy can be obtained on the planet from solar rays that are outside its field, as this ray energy reaches 1376 kilowatts per square meter, while the solar radiation energy benefited from it is one kilowatt. Only for every square meter on the earth during the noon time on sunny days, given that the sun at that time is perpendicular to the earth, and this energy decreases after that time.

The solar rays that reach the earth consist of two parts; The first is the rays that arrive directly from the sun, and can be benefited from by focusing them through lenses and mirrors designed for that, and the other is the scattered rays that come from the celestial dome, and can be used when the sky is clear, and these rays represent 15% of the total rays .

Exploiting solar energy in Egypt

The Egyptian country is one of the regions located in the middle region of the solar belt in the world, because it is confined between latitudes 22 degrees and 31.5 degrees towards the north, and for this reason it is one of the most global countries that exploit solar energy. Several studies in order to know the characteristics of radiation in Egypt, and through which the extent of the amount of solar energy that can be exploited throughout the year was known.

Summary of results

  • The total area of ​​the country extending from the capital, Cairo to the southern parts, benefits about six kilowatt hours per square meter per day, while the value of energy from the northern parts to the southern parts is five kilowatts per hour, and in the North Coast region is seven kilowatts. The results are given that the country receives about 4000 hours of sunshine annually, and twenty clear days without clouds.
  • The country receives from scattered solar radiation about two kilowatt-hours per square meter per day, and this represents 40% of the value of radiation that the country receives from the value of total solar energy.

Thermal solar energy

There are many applications that are applied in the country to solar thermal energy for domestic and public heating operations such as (government and private departments, banks, camps, and hospitals), and the heating process includes water and air that are important in many industrial processes, and it is also used in power generation. electrical; As Egyptian families rely on this technology, which contributes to rationing expenditures on families and families.
