What is Solar Energy? How is It Obtained?
Solar energy is a form of electromagnetic radiation emitted from the Sun. This radiation carries energy such as light and heat, and when it reaches the Earth, it can be used in various ways. The methods of obtaining solar energy are as follows:
Photovoltaic (PV) Cells: Solar panels or photovoltaic cells convert sunlight directly into electrical energy. These cells are usually made of semiconductor materials such as silicon and generate electricity when exposed to sunlight. This electricity can be used in homes, workplaces or remote areas that are not connected to the grids.
Solar Collectors and Thermal Energy: Solar collectors are used to convert solar energy directly into thermal energy. These collectors usually consist of black-colored surfaces that absorb sunlight. The resulting heat is used for energy production or heating, usually by heating or evaporating water.
Condensed Solar Energy (CSP): In this method, mirrors or lenses are used to focus sunlight. Focused solar energy is usually concentrated at one point, and this heat is used to provide electricity generation, usually by turning turbines.
Solar Cells: Solar cells are small and portable devices that convert solar energy directly into electrical energy. These batteries can be used to support small solar-powered devices, calculators or various portable electronics.
The process of obtaining solar energy involves the stages of capturing sunlight in some way, converting this light into a form of energy, and then using or storing it as electrical energy or thermal energy. Solar energy stands out as a sustainable, environmentally friendly and renewable energy source.
