Solar energy and its systems. The solar energy sector is one of the most important sectors in the world, because it constitutes an important economic pillar for many countries, especially in the Middle East.<\/span><\/span><\/p>\n

The sun provides us with heat and light, which are the basis of life. It consists of a fiery gaseous mass about a million times the size of the Earth, and its diameter is more than 100 times larger than the Earth.<\/span><\/span><\/p>\n

The temperature of the center of the sun reaches more than 15 million degrees Celsius, and powerful rays emerge from it that reach the Earth after passing through outer space for a distance of 150 million kilometers, but what actually reaches us is a very small percentage of the power of the rays that come out of the sun, and it is the part that supplies Earth energy.<\/span><\/span><\/p>\n

It is known that the countries located on the equator are the countries that enjoy approximately one season throughout the year, which is summer, and thus the sun\u2019s rays remain present in these countries throughout the year.<\/span><\/span><\/p>\n

<\/div>\n

Countries near the equator also enjoy this weather, while residents of the northern and southern regions of the equator are aware of the four seasons during the year.<\/span><\/span><\/p>\n

Solar radiation<\/span><\/span><\/h2>\n

Solar radiation is known as the power incident per unit area, and the most popular unit used to measure it is the watt per square meter (W\/m2). The unit is used in solar energy systems to determine efficiency and other uses.<\/span><\/span><\/p>\n

In general, on sunny days, the largest amount of solar radiation that reaches the Earth is the rays of noon, when sunlight is perpendicular to the Earth\u2019s surface, while at sunrise and sunset, the Earth receives the least amount of radiation throughout the day.<\/span><\/span><\/p>\n

The effect of clouds on solar radiation<\/span><\/span><\/h2>\n

The amount of solar radiation that reaches the Earth varies from one period to another due to changing weather conditions and the changing position of the Earth in relation to the Sun during one day and throughout the year.<\/span><\/span><\/p>\n

There are many weather factors that mainly affect the amount of sufficient solar radiation reaching the Earth, including clouds, as clouds reduce the amount of solar radiation depending on the amount of clouds and may even block the sun’s rays from the Earth in the winter.<\/span><\/span><\/p>\n

As we mentioned, the maximum value of the amount of solar radiation that radiates on the Earth\u2019s surface is at noon. This amount changes depending on the hours of the day and the location, in addition to some weather effects such as the presence of clouds.<\/span><\/span><\/p>\n

Solar beams reaching Earth<\/span><\/span><\/h2>\n

There are three types of radiation reaching the Earth, which represent 50% of solar radiation:<\/span><\/span><\/p>\n
