Photovoltaic panels, commonly known as 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 solar farms. They are a key component of renewable energy systems, helping to reduce reliance on fossil fuels and lower greenhouse gas emissions. As technology advances, photovoltaic panels are becoming more efficient and affordable, making solar energy more accessible to everyone.
