Can I run my whole house off-grid with solar?

By South West Tech

Yes.

A well-designed off-grid solar system can power an entire home without being connected to the electricity grid. In fact, many rural homes, stations and remote properties across Australia rely entirely on off-grid solar, battery storage and, in some cases, a backup generator.

The key is ensuring the system is correctly sized for your energy usage. Your solar panels need to generate enough electricity during the day, while your battery bank needs enough storage to power your home overnight and through periods of poor weather. Larger homes or properties with high-energy appliances may require larger solar arrays and battery systems.

If you're thinking about going off-grid, the first step is understanding how much electricity your home uses.

Our Off-Grid Load Calculator helps estimate your daily energy consumption, while our Solar System Size Calculator and Off-Grid Battery Size Calculator can help estimate the solar panel and battery capacity needed to power your property.
