Solar system types compared: Grid-tied, off-grid, and hybrid
Grid-tied solar systems. Grid-tied systems are solar panel installations that are connected to the utility power grid.With a grid-connected system, a home can use the solar energy produced by its solar panels and electricity that comes from the utility grid.. If the solar panels generate more electricity than a home needs, the excess is sent to the grid.
