Solar panels are devices that convert sunlight into electricity using photovoltaic cells. They harness renewable energy from the sun, making them a sustainable choice for power generation. Typically installed on rooftops or in large solar farms, solar panels reduce reliance on fossil fuels, lower electricity bills, and contribute to a cleaner environment by decreasing greenhouse gas emissions. As technology advances, solar panels become more efficient and affordable, making solar energy an increasingly popular option for homes and businesses.
