Solar energy is the energy obtained from the Sun’s radiation and is a renewable and sustainable source of power. It can be converted into electricity using photovoltaic systems or into heat using concentrated solar power systems. Solar energy is abundant, environmentally friendly, reduces electricity bills, and requires low maintenance. However, it also has challenges, such as dependence on sunlight, high initial costs, and space requirements for large installations. Globally, solar energy use is growing rapidly, supported by technological advancements and government policies that encourage adoption. The future of solar energy looks promising, with innovations improving efficiency and sustainability.
