How does solar energy work?

Solar energy works by harnessing sunlight and converting it into usable electricity or heat. The process begins with solar panels, which are made up of many individual solar cells, typically composed of silicon. When sunlight hits these solar cells, photons from the sunlight are absorbed, generating electrons and creating a flow of electricity through the silicon material. This direct current, or DC electricity, produced by the solar cells is then transformed into alternating current, or AC electricity, by an inverter. AC electricity is the form of electricity commonly used in homes and businesses, allowing consumers to power their electrical appliances and other equipment. Solar energy systems can also include batteries for energy storage. This storage capability allows homeowners or businesses to use the electricity generated even when the sun is not shining, providing greater reliability and flexibility. In addition to photovoltaic systems for electricity generation, solar energy can also be harnessed for heating purposes through solar thermal systems. These systems collect sunlight to heat water or air for residential or commercial heating applications. Overall, solar energy is a clean and renewable resource, contributing to the reduction of greenhouse gas emissions and reliance on fossil fuels. Given its ability to provide sustainable energy, many individuals and organizations are increasingly turning to solar power as a viable energy solution.
