Solar panels are devices that convert sunlight into electricity. They are made up of many small units called solar cells, which are typically made from silicon. When sunlight hits these cells, it creates an electric current that can be used to power homes, businesses, and even vehicles. These panels are often installed on rooftops or in large fields, where they can capture the most sunlight. Using solar panels helps reduce reliance on fossil fuels and lowers greenhouse gas emissions, making them an important part of the transition to renewable energy sources like solar energy.
