A grid-tied electrical system, also called Tied to grid or Grid tie system, is a semi-autonomous electrical generation or grid energy storage system which links to your utility compamy to feed excess energy back to the local  electrical grid.

Direct Current electricity (DC) energy is passed to an inverter which is grid tied. The inverter monitors the alternating current (AC) supply waveforms and generates electricity that is phase matched. The DC electrical system is attached to the Utility lines via this mechanism.

Because the local system is phase matched, electricity can be drawn from the Utility in the situation of a generating shortfall.

What are the parts of a grid-tied solar energy system?

Using a grid inter-tied solar electricity system, you may collect all or part of your home's energy needs. A grid inter-tied solar energy system has these parts or components to it:

    * Solar panels (called a panel array)
    * An inverter changes direct current electricity (DC) to alternating current (AC)
    * Wiring

Those listed above are primary, but there are some others, too, including:

    * An array DC disconnect halts electricity from the panels, during maintenance.
    * The breaker panel (or "fuse box")
    * A Kilowatt Hour Meter, used by the utility company to calculate electricity bills.
    * A Utility Disconnect allows your local utility company to disconnect the system when they are doing maintenance work on wires near your house.
