In a grid connected PV system, also known as a “grid-tied”, or “on-grid” solar system, the PV solar panels or array are electrically connected or “tied” to the local mains electricity grid which feeds electrical energy back into the grid. In the previous tutorial we looked at how a stand alone PV system uses photovoltaic panels. . Each solar panel contains multiple photovoltaic (PV) cells that capture sunlight and convert it into DC (direct current) electricity. While solar panels generate DC electricity, the grid operates using AC (alternating current) electricity. It covers system configurations, components, standards such as UL 1741, battery backup options, inverter sizing, and microinverter systems. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations.
