I've been hearing a lot about the benefits of solar energy, but I'm not sure I understand how it works. Can you give me some more information on this?

Solar energy is derived from the sun's radiation that is converted into usable forms of energy such as heat and electricity. The process involves using photovoltaic cells to convert sunlight into direct current (DC) electricity which can then be used for various purposes. Photovoltaics are made up of two main components: semiconductors and conductors. When light hits the semiconductor, electrons are knocked loose from their atoms and flow through the material creating an electric current. This current is then collected by the conductor and turned into useful electrical energy.
