Although they are most common in remote locations without utility service, off-grid solar-electric systems can work anywhere. These systems operate independently from the grid to provide all of a household’s electricity. That means no electric bills and no blackouts. People choose to live off-grid for a variety of reasons, including the prohibitive cost of bringing utility lines to remote home sites, the appeal of an independent lifestyle, or the general reliability a solar-electric system provides. Two key components are batteries to store energy and an engine-generator which can provide energy during periods of cloudy weather.
Those who live off-grid often make adjustments to when and how they use electricity, so they can live within the limitations of the energy available. This doesn’t necessarily imply doing without, but rather is a shift to a more conscientious use of electricity.
