Off-grid solar can suit homes in remote areas where connecting to the electricity grid is difficult or costly. Unlike a grid-connected system, it must meet your needs during cloudy weather and overnight, so it usually includes solar panels, batteries, an inverter and sometimes a backup generator. System size depends on your electricity use, location, available sunlight and plans for future appliances, while costs and maintenance can be higher than staying grid-connected. Ask a licensed installer to assess the property and check relevant electrical and building requirements before deciding.
