Residential solar power with a grid connected system

Grid Connected Solar, Grid-Tied Solar and On-Grid Solar all refer to the same type of solar powered electrical system - one that is connected to the national electricity grid.

Most homes in New Zealand are already connected to the national electricity grid, so most of the systems we install are grid connected. By adding PV (photovoltaic) solar panels to your home, you can generate direct current (DC) energy from the sun. This energy is then converted from DC electricity into AC (alternating current) electricity suitable for ordinary household use, by either a string inverter or micro inverters. Houses with grid connected solar systems consume their free solar power first and then if more electricity is required than their solar system generates, the rest of the household's electricity need is purchased from the grid. Any excess solar energy not required by the household can be sold to the grid.
