Solar energy technologies harness the power of the sun to generate electricity and heat. The most common method is through solar panels, which convert sunlight into electricity using photovoltaic cells. These panels can be installed on rooftops or in large fields, making them versatile for both homes and businesses. Another important technology is solar thermal energy, which uses sunlight to heat water or air for residential and industrial use. This method is often used in solar water heaters and can significantly reduce energy costs. Together, these technologies contribute to a cleaner, more sustainable energy future.
