Solar panel systems convert sunlight into electricity using photovoltaic cells. These cells are typically made from silicon and are arranged in panels that can be installed on rooftops or in open areas. When sunlight hits the panels, it generates direct current (DC) electricity, which can be converted into alternating current (AC) electricity for use in homes and businesses. In addition to providing clean energy, solar panel systems can reduce electricity bills and lower carbon footprints. Many systems are connected to the grid, allowing users to sell excess energy back to utility companies. Government incentives and rebates often make installation more affordable for homeowners and businesses.
