Solar energy systems convert sunlight into usable energy, primarily electricity or heat. They typically consist of solar panels, which capture sunlight, and inverters, which convert the captured energy into a form that can be used in homes or businesses. These systems can be installed on rooftops or in large fields, known as solar farms, to harness solar power efficiently. There are two main types of solar energy systems: photovoltaic (PV) systems, which generate electricity directly from sunlight, and solar thermal systems, which use sunlight to heat water or air. Both types contribute to reducing reliance on fossil fuels and lowering greenhouse gas emissions.
