Solar energy is heat and bright light, the source of which is the Sun. It is a type of clean energy; they do not have the burden of polluting the environment such as smoke, gas, carbon monoxide, sulfur and radiation. Thanks to such features, one of the works that the Evadore Ecosystem will do to reduce carbon emissions in the world will be to expand the use of solar energy. Solar energy is the radiation energy released by the fusion process in the core of the Sun. Our sun is a nuclear reactor and emits tiny packets of energy that reach the earth in 8.5 minutes from a distance of 150 million km. Within each hour, photons sufficient to meet the energy needs of our world for 1 year reach the earth. The conversion of hydrogen gas in the sun to helium is caused by the fusion process. The intensity of solar radiation on the surface of the Sun is about 6.33 x 107 W/m2. The intensity of solar radiation outside the Earth's atmosphere is approximately constant and is 1370 W/m2 (Watt/m2); however, it varies between 0-1100 W/m2 values on earth. Even a small fraction of this energy coming to Earth is many times more than the current energy consumption of humanity. The sun has great potential for energy production. The worldwide solar market is growing rapidly, reaching 849 GW by the end of 2021, accounting for 27.71% of the world's total renewable power in terms of installed power. Solar energy has established itself as an environmentally clean primary energy source.
The principle of operation of a solar panel is based on the following: When photons hit solar cells, they excite electrons, causing them to separate from their atoms. If the conductors are connected to the plus and minus sides of the solar cells, an electrical circuit is formed, and electricity is generated if electrons flow through such a circuit. A large number of solar cells come together to form a solar panel, and a large number of solar panels come together to form a solar energy system. The more solar modules there are in a solar system, the greater the installed power of the system.
If we talk a little more about the amount of energy; The Sun's rays reaching a unit area in space, on Earth's orbit, are 1,366 W/m2 when measured on a surface perpendicular to the Sun. This value is also referred to as the solar energy constant. The planetary atmosphere reflects 6% of this energy and absorbs 16%, making it the highest solar energy achievable at sea level at 1,020 W/m2. Clouds reduce incoming radiation by about 20% by reflection and about 16% by absorbing. The sun is among the inexhaustible sources of energy. Therefore, there is no need for any fuel for the use of solar energy. Solar energy is a very important source of energy thanks to these and similar benefits, it helps to reduce the ecological footprint by reducing environmental pollution.
