A solar photovoltaic (PV) power plant is an innovative energy solution that converts sunlight into electricity using the photovoltaic effect. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations. This process occurs when photons from sunlight strike a material, typically silicon, and displace electrons, generating a direct current (DC).
