You get your electricity bill and feel frustrated. You soon wonder what it would be like to disconnect from the grid. No more retailers, standing charges, or yearly price hikes—just your own system working for you.
Or you’ve bought land in a rural area, and someone tells you how much it costs to get a grid connection. The price sounds unbelievable.

Why People Want to Go Off-Grid (And Where the Idea Comes From)
It’s easy to see why people are interested. Electricity prices in Australia keep going up, and many people would love to stop dealing with their energy retailer. Having full control over your energy supply is a very appealing idea.
Many people think going off-grid means no electricity costs. In reality, off-grid solar doesn’t remove costs; it just changes them.
You’ll pay for the system upfront, buy generator fuel, and take on the job of managing your own power. For some, this trade-off is worth it. For others, it’s not. The important thing is to know where you stand.
What Does a Grid Connection Cost Versus an Off-Grid Solar System?
The financial decision usually comes down to one thing: how much does it cost to connect your property to the grid compared to installing an off-grid system?
For suburban homes with grid access, the choice is simple. The connection is already there, and going off-grid rarely makes sense financially. For rural and remote properties, it’s a different story. Connecting these places to the grid can mean:
- A new transformer to service the area.
- Overhead power lines run across long distances.
- A Level 2 electrician to complete the physical connection.
- Ongoing network charges and retailer fees from day one.
Setting up a new rural grid connection can cost tens of thousands, sometimes even more. An off-grid system, even a large one with a good generator, can cost much less upfront.
In these cases, off-grid solar not only lowers future bills but also reduces your dependence on the grid. It helps you avoid a big expense right away.

A Real-World Example: When the Numbers Change Everything
Here is how that comparison plays out in practice.
Imagine a rural property that needs a new grid connection. The network operator must install a transformer, run lines to the property, and set up the connection.
The infrastructure alone can cost over $100,000. After that, a Level 2 electrician finishes the job, and you start paying retailer and network fees.
Now compare that to an off-grid solar system built to meet the same energy needs: panels, a battery bank, a controller like the Sigenergy SigenStor, and a backup generator.
Even for homes that use a lot of energy, the off-grid system can cost much less than connecting to the grid, saving you tens of thousands upfront. In the end, you still get power to your house, just in a different way.
The real question is which option costs less for your situation.
The Pros of Off-Grid Solar
For properties where the numbers add up, the benefits of going off-grid are real and long-lasting:
- Lower upfront cost than a remote grid connection in many rural areas.
- No electricity retailer, no standing charges, no annual price increase letters.
- No exposure to network outages or policy changes that affect your costs.
- Off-grid batteries qualify for the federal Cheaper Home Batteries Program rebate.
- Modular systems like the Sigenergy SigenStor let you add capacity over time.
- Modern systems automatically start and stop the generator, with no manual input required.
The Cons of Off-Grid Solar
The downsides are real, and any installer who ignores them isn’t being honest:
- No silent backup: when batteries run out, the generator is your only fallback.
- Generator maintenance: weekly test-starts and an annual service are non-negotiable.
- Fuel costs money and needs safe on-site storage, which matters in remote areas.
- Bad weather means you have to actively manage your system by watching battery levels and limiting high-use appliances during cloudy periods.
- Off-grid systems need to be sized more carefully than grid-connected systems, which increases the upfront cost.
- For suburban properties with existing grid access, the cost almost never justifies going fully off-grid.

Who Off-Grid Solar Is Genuinely Good For
Off-grid solar makes financial and practical sense in some situations. The best candidates are:
- Rural and remote property owners who face high costs to connect to the grid.
- Properties where no grid connection exists, and establishing one requires substantial new infrastructure.
- Landowners who want complete energy independence and have a property that can support a properly sized system.
- People who already own a generator that’s the right size, which lowers the cost of going off-grid.
- Properties with enough roof, shed, or ground space to generate enough solar power to cover daily use.
Who Off-Grid Solar Is NOT Good For
The truth is, many people researching this topic fall into this category. Off-grid solar is unlikely to make financial sense if:
- You already have a grid connection with low ongoing network charges.
- You’re in a suburban or semi-rural area where a grid-connected solar and battery system gives you similar independence at a lower cost.
- Your energy use is high and unpredictable, which makes it hard to size a system reliably without making it very large and expensive.
- Your budget is tight because undersizing an off-grid system creates ongoing shortfalls that a grid-connected system avoids.
- You want a low-maintenance setup, but off-grid systems need more hands-on management than most people expect.
It’s understandable to feel frustrated with electricity retailers. But for most urban and suburban households, disconnecting from the grid isn’t the best solution.
A good grid-connected solar and battery system lets you generate your own power and use the grid as a backup when needed, often at a lower cost.

Wrapping Up: Off-Grid Dreams, On-Grid Reality
Now you have both sides of the picture. Going off-grid is not the money-saving escape from electricity retailers that most people imagine it to be. But for the right property in the right situation, it’s one of the smartest financial decisions an Australian homeowner can make.
Knowing which side of that line your property falls on is the most important step before you make any decision.

FAQ: Pros and Cons of Off-Grid Solar
What are the main pros and cons of off-grid solar?
The main pros are avoiding expensive rural grid connections, getting rid of retailer fees, gaining energy independence, and qualifying for the federal battery rebate. The main cons are losing the grid as a backup, needing regular generator maintenance, paying for fuel, and facing higher upfront costs for a well-sized system.
Who should consider going off-grid with solar?
Off-grid solar is best for rural and remote property owners, especially when a new grid connection would cost tens of thousands of dollars. If grid infrastructure costs more than an off-grid system, going off-grid is the logical financial choice.
Who should avoid going off-grid with solar?
Most suburban and semi-rural homeowners with existing, affordable grid access should avoid going fully off-grid. The upfront cost and ongoing maintenance responsibilities rarely deliver better value than a grid-connected solar and battery setup.
Will going off-grid save me money on electricity?
It depends on your starting point. In rural areas with high grid connection costs, an off-grid system can save significant money upfront and eliminate ongoing charges. In suburban areas with existing grid access, the savings rarely justify the extra cost and complexity.
Do I still pay electricity bills if I go off-grid?
No. Once you go fully off-grid, you won’t have a retailer or a bill. Your costs will be for the system, generator fuel, and maintenance. Whether this is cheaper than your current electricity spending depends on your usage and energy costs.
Is off-grid solar eligible for the federal battery rebate?
Yes. Off-grid batteries qualify for the same Cheaper Home Batteries Program rebate as grid-connected systems. The battery must be CEC-approved and installed by a SAA-accredited installer.
What maintenance does an off-grid solar system need?
The main thing to maintain is the generator: start it once a week and get it serviced once a year. The battery and panels need regular checks, just like any solar system. You’ll also need to keep a closer eye on battery levels than with a grid-connected setup.
Can I go off-grid if I already have grid power available?
Technically, yes, you can go off-grid if you already have grid power. But it rarely makes financial sense. If your grid connection is already in place and affordable, a grid-connected solar and battery system gives you similar independence at a lower cost and with less responsibility.
