Radiation (radiation) is the transfer or emission of energy in the form of electromagnetic waves or particles. All of the elements that cause radioactive materials to emit rays such as alpha, beta, gamma or any electromagnetic radiation emitted in space are called radiation.
Everything emits and absorbs electromagnetic radiation. Sources such as the sun, tungsten filaments or infrared emitters have emission spectra. However, their spectral distributions are different, having slightly different spectral shapes and fine spectral details in the case of the sun.
Only 2,2 billionth of the energy emitted from the sun reaches the earth and constitutes the main energy source of the world. Solar radiation first interacts with the atmosphere and the total solar radiation intensity reaching the earth is reduced by half. The total solar radiation reaching the earth is of two groups: direct radiation and diffuse radiation.
9 percent of the rays coming from the sun are in the ultraviolet region, 45 percent in the visible light region, and 46 percent in the infrared region. Radiation distribution reaching the earth is not homogeneous, it varies depending on the angle of incidence and time.
Today, electricity is generated from solar energy using thermal and photovoltaic methods. Solar radiation (solar irradiation factor) has a very large effect on power output. Solar irradiation is also expressed as solar intensity or solar radiation. According to research, the average total annual sunshine duration in our country is 2640 hours. The average annual total radiation intensity has been determined as 1311 kWh/m2 (daily total 3.6 kWh/m2). The current produced in a photovoltaic panel increases with solar radiation. Large variations in radiation significantly change the current, but the voltage remains almost constant.
Solar radiation factor is important in determining the regions where solar power plants will be established. Solar energy is essentially the conversion of rays from the sun into electrical energy with special technologies. Solar energy is the most abundant and clean energy available on earth today. Moreover, it is a renewable and sustainable energy. Today, solar energy is used in more and more areas.
Our organization also provides radiation factor testing services with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
