Solar energy Solar energy, or what is called solar radiation, (in English: solar energy), which is the energy emitted from the sun's rays mainly in the form of heat and light, and it is the product of nuclear reactions inside the star closest to us, which is the sun, and this energy is of great importance The amount of this energy produced far exceeds the current energy requirements in the world in general, and if it is harnessed and exploited appropriately, it may meet all future energy needs.

The importance of solar energy The importance of solar energy lies in the beginning. That the sun's rays have facilitated the evolutionary processes in living organisms, which are responsible for the photosynthesis processes in plants to produce food and biomass, in addition to the role of these rays in energy. Hydropower and wind energy.

Also, there is a great importance of solar energy in cultivating the land, producing and growing crops, and drying food to prevent it from spoiling, in addition to using greenhouses to raise heat.

In addition, solar energy is responsible for the so-called group of renewable energy sources. The most important of them is, and it is noticeable the increasing importance of solar energy as a source of renewable energy because it does not diminish and has a non-polluting nature, at a time when there has become a marked decrease in the levels of fossil fuels, oil and coal, in addition to natural gas. On the exploitation of solar energy in our lives, including ancient and modern ones that keep pace with the technology of the era, and the most famous of them are:
