Solar energy is the energy that comes from the sun and has been used by humans for a long time for things like heating, cooking food, removing salt from sea water and many other things.
Solar energy is the light and heat emitted from the sun, and this energy is of great importance in the globe, as all living things in the earth depend on the energy of the sun. The water on Earth's surface and the formation of clouds that eventually provide fresh rainwater.
Solar energy is produced through thermonuclear fusion reactions in the depths of the sun, and these reactions release a large amount of energy to maintain the surface temperature of the sun at 10,300 Fahrenheit (5,700 degrees Celsius), and although solar energy is the largest source of energy received by the Earth, its intensity On the surface of the earth, it is very low, due to the great distance between the earth and the sun, and the earth’s atmosphere, which absorbs and scatters radiation. The energy that reaches the earth’s surface through the atmosphere on a clear day when the sun is directly above the earth does not exceed approximately 30%, and when the sun is close to the horizon and the sky Overcast, the solar energy at the ground level is very small, and the amount of radiation on the surface of the earth varies from one point to another.
The total amount of solar energy received by the Earth greatly exceeds the amount used in the world, but if harnessed appropriately, this highly widespread source has the potential to meet all future energy needs. Continuous and renewable energy that does not cause pollution, and on the other hand, the limited uses of fossil fuels that cause pollution, such as coal, oil and natural gas, will decreas
