Solar panels are devices that convert sunlight into electricity, harnessing the power of the sun to provide a clean and sustainable energy source. They are made up of many solar cells, typically composed of silicon, which generate direct current (DC) electricity when exposed to sunlight. The electricity produced by solar panels can be used to power homes, businesses, and even feed back into the grid. As technology advances, solar panels are becoming more efficient and affordable, making them an increasingly popular choice for reducing carbon footprints and promoting energy independence.
