Grid-tied PV is a solar electricity system that is connected to your utility meter. Solar generated power from grid-tied systems is first used by your home or business needs while any excess capacity is sent to the utility grid (sold at retail price to the utility). During the evening or times when your power demand exceeds your solar production, your home will run off of utility power.
