How does solar energy work?
Solar energy works by using photovoltaic (PV) cells in solar panels to convert sunlight (photons) into direct current (DC) electricity, which is then sent to an inverter to change it into alternating current (AC) for use in homes and businesses, with excess energy often stored in batteries or sent to the grid. This process relies on the photovoltaic effect, where sunlight excites electrons in semiconductor materials like silicon, causing them to flow and create an electric current.
