Grid-Tie Solar Power Systems
Grid-tied, also referred to as grid-connected and grid-interfacing, solar photovotaic systems are made up of several components that, when wired together, are capable of producing alternating current electricity using light from the sun.
These systems are designed to offset utility power usage and to compensate system owners for any excess wattage their systems produce through an arrangement known as "net metering".
This arrangement is, essentially, an electric power plant that is owned and operated by the home or business owner.
