A solar panel is a device that converts sunlight into electricity. It is made up of many small units called solar cells, which are usually made from a material called silicon. When sunlight hits these cells, it creates an electric current that can be used to power homes, businesses, and even electric vehicles. Using solar panels is a great way to harness renewable energy, helping to reduce our reliance on fossil fuels. They can be installed on rooftops or in large fields, making them versatile for different locations. By using solar energy, we can also lower our electricity bills and contribute to a cleaner environment.
