A solar power plant is a facility designed to convert solar energy into electrical energy. Unlike traditional thermal power plants that operate using fossil fuels, solar power plants utilize a completely environmentally friendly energy source — sunlight. The electricity generated by solar panels is in the form of direct current (DC). However, most electrical grids and devices operate on alternating current (AC). Inverters convert DC power into AC, making it compatible with the grid. After conversion, the electricity is transmitted through substations and transformers, from which it either flows directly into the grid or is used to supply power to on-site facilities. To optimize performance, a photovoltaic plant also includes a meteorological station, which analyses environmental conditions to determine the intensity and short-term evolution of solar radiation, as well as the exact time of sunset.
