No, a Net-Zero Energy home is not the same as a grid-disconnected home. XeroHome’s calculations assume that the home is connected to a grid with a net-energy metering infrastructure. In other words, at times when the home needs energy and solar energy from rooftop-solar is insufficient or not available, the home will draw energy from the grid. Conversely, when excess solar energy is being produced by the home’s rooftop solar, that energy is returned back to the grid. Also, as described above, a Net-Zero Energy home may still use natural gas for heating. In those cases, the home will continue to require a utility connection for natural gas.
Does a Net-Zero Energy home mean I can disconnect my home from the utility grid? Print
