Thinking about ditching the power companies for good?
Going off-grid with solar is a brilliant move — but only if you set it up smart.
The best way these days? Partial battery backup.
Saves you a bucketload of cash, keeps you running almost all the time, and leaves room to grow later if you need.
Let’s run through how it works — and why it’s the smart move for Aussies everywhere.
You don’t need a battery to cover 100% of your usage.
Most folks do way better with a battery that handles around 70% of their daily needs.
Why?
Because:
It’s the new common-sense approach.
Especially good if you’re in places with heaps of sunshine most of the year.

Ballarat’s a tough gig for solar in winter.
Short days, cold mornings, endless clouds.
If you can make a system work there, it’ll work anywhere.
Here’s what a 1kW system pulls in Ballarat:
| Month | Average Solar Radiation (kWh/m²/day) | Monthly AC Output (kWh) |
|---|---|---|
| May | 3.25 | 82 |
| June | 2.90 | 72 |
| July | 2.87 | 74 |
In June, you’re getting around 2.4kWh per day off 1kW of panels.
Not a lot — but still enough if you design it right.
Keen to see what panels perform best? See our solar system range.
Say your place pulls about 17kWh a day — pretty typical for a family home.
If your battery’s covering 70% (around 12kWh), then your solar needs to:
End of the day, you’re chasing about 17kWh from solar each day.
In a Ballarat winter, that means installing roughly:
| Solar Size | Winter Daily Output |
|---|---|
| 7.1kW | ~17kWh |
✅ So even in rough old June, a 7.1kW system paired with a 12kWh battery gets you through.

If you’ve got the roof space, fill it.
Simple as that.
More panels today means less headaches tomorrow.
That’s true whether you’re in Ballarat, Byron, or out the back of Bourke.

Large off-grid properties place very different demands on a system. Multiple occupants, guest accommodation, events, workshops or seasonal peaks can create substantial loads that require careful planning from the beginning.
Three-bedroom homes often grow into their power requirements. Children get older, appliances multiply, and what feels sufficient today can quickly become restrictive. That’s why we design beyond immediate needs.
