Solar energy is the radiant light and heat from the Sun that has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar energy technologies include solar heating, solar photovoltaics, solar thermal energy, solar architecture, and artificial photosynthesis.

Solar Radiation

Solar radiation is the electromagnetic radiation emitted by the Sun. It provides the energy that sustains life on Earth and drives the Earth's climate and weather. Solar radiation is often utilized to produce electricity using photovoltaic cells, to heat water or air using solar thermal collectors, and to generate electricity through solar power plants.

Solar Panels

Solar panels, also known as photovoltaic panels, are devices that convert light into electricity. They are made up of multiple solar cells, which are made of semiconducting materials such as silicon. When light strikes the cells, it creates an electric field that generates electricity.

Solar Energy Applications

Solar energy has a wide range of applications, including:

Residential and commercial solar power systems
Solar water heating systems
Solar-powered outdoor lighting
Solar-powered vehicles and transportation
Solar-powered desalination plants
