An off-grid system is not connected to the electricity grid and therefore requires battery storage. An off-grid solar system must be designed appropriately so that it will generate enough power throughout the year and have enough battery capacity to meet the home’s requirements.

Off-grid electrification is an approach to access electricity used in remote areas with little access to electricity, due to scattered or distant population. The term off-the-grid (OTG) can refer to living in a self-sufficient manner without reliance on one or more public utilities. People who adopt this lifestyle are called off-gridders.

Off-the-grid is a system and lifestyle designed to help people function without the support of remote infrastructure such as an electrical grid. In electricity, off-grid can be a stand-alone power system or micro grids typically to provide a smaller community with electricity.
