Brief introduction to solar photovoltaic power generation
Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations.
