Off-grid solar can suit homeowners in remote areas, but the system must be sized for your electricity use, local sunlight and periods of poor weather. You will generally need solar panels, a battery bank, an inverter, monitoring equipment and often a backup generator, along with careful energy management. The upfront and replacement costs can be higher than a grid-connected system, so compare long-term costs and reliability before deciding. A qualified solar installer or electrician can assess your property, while energy.gov.au provides general guidance on solar and batteries.
