PV Systems |
||||||||||
By themselves, modules or arrays do not represent an entire PV system. The primary components of a grid-connected system would include structures to put them on (which might be a roof, covered parking, or a stand -alone rack that is stationary or that tracks the sun) and inverters that take the direct-current (DC) electricity produced by the modules and "condition" that electricity, usually by converting it to alternate-current (AC) electricity used in residential, commercial and industrial applications. |

Stand-alone systems for applications where utility grid-power is not available, also incorporate a battery storage system. This system is often a hybrid system that incorporates a wind and/or a gas-powered generator. Due to the high cost of bringing in utility power and the rising cost per kWh, the cost of installing a stand-alone hybrid system can be just a fraction of, or in some cases, less expensive than bringing utility power to the site. |
