Straight answers before you commit
The questions we hear most about going solar in Australia: what it costs, what you save, which rebates apply, and how the whole job actually runs. All figures are indicative and confirmed in your written quote.
What it costs
It depends on size and site, but as a guide a 4kW system usually lands around $3,000 to $6,000, a 6.6kW around $4,000 to $8,000, and a 10kW around $8,000 to $14,000 before rebates. Rebates bring the upfront cost down further. Your written quote confirms the exact figure for your roof.
Mostly the hardware and the workmanship. Cheaper quotes often use budget panels and inverters, skip the little things that make a roof last, or leave rebate handling to you. We quote quality gear with real warranties and the rebates already worked in, so you are comparing the full picture rather than a headline number.
Many households spread the cost with an interest-free or low-interest plan, and in Victoria an interest-free Solar Victoria loan is available to eligible homeowners to cover part of the system. Tell us your situation in your quote and we will lay out the options that apply to you.
Yes for most homes with reasonable daytime usage. The federal STC discount does reduce a little each year, but power prices and the value of self-generated energy remain high, so a well-sized system still typically pays for itself in about four to seven years.
What you save
Most homes cut a large share of their grid electricity, and a well-sized system usually pays for itself in about four to seven years. The exact saving depends on your usage, your tariff and how much power you use during daylight hours, when your panels are generating.
For a well-sized home system after rebates, payback is commonly in the four to seven year range. After that the system keeps generating for many more years, so the savings continue well past the point where it has paid for itself.
Yes. Any solar you generate but do not use is exported to the grid and you earn a feed-in tariff for it. Feed-in rates have fallen over the years, so the bigger win is using your own solar directly during the day, or storing it in a battery for the evening, rather than selling it cheaply.
Shift heavy loads like the dishwasher, washing machine and pool pump to daylight hours so you run them on your own solar. Adding a battery lets you use daytime solar at night. We size your system around how and when you actually use power so more of it offsets what you would have bought.
Rebates and eligibility
Federal small-scale technology certificates (STCs) apply Australia-wide and come off the price of most solar systems, typically worth around $1,600 to $1,800 on a 6.6kW system. Victorian homeowners may also access the Solar Victoria panel rebate of up to $1,400, and a federal battery incentive is available. We check what you qualify for and handle the claims.
Yes. A federal battery incentive is in place, worth roughly $250 to $270 per usable kWh in 2026, which knocks a meaningful amount off a home battery. Some states add their own support on top. Exact amounts depend on the battery you choose and current program rules, and we confirm them in your quote.
Victorians can stack the federal STC discount with the Solar Victoria panel rebate of up to $1,400 and, for many, an interest-free Solar Victoria loan. There is also the Victorian Energy Upgrades program and a state feed-in tariff. See our Victorian rebates page for the detail, or ask us to work it into your quote.
No. Handling the rebate paperwork is part of the job. We confirm your eligibility up front, lodge the claims, and factor the savings straight into your written quote so the price you see already reflects them.
Battery storage
Either works. A battery lets you use your own solar after dark and adds backup, and the numbers keep improving as battery incentives roll out. If you are not ready, we can size a solar system that is battery-ready so you can add storage later without reworking the setup.
In most cases, yes. We can add a compatible battery to an existing solar system, and if your current inverter is not battery-ready we will tell you honestly what is involved. Send us your setup and we will advise what fits.
Many home batteries can provide backup for essential circuits during an outage, but it depends on the battery and how it is wired. If blackout protection matters to you, tell us and we will size and configure the system to deliver it.
Warranties and hardware
You get the manufacturer's product warranties on the panels, inverter and battery, a typical 25-year performance warranty on the panels, and workmanship cover on the installation itself. We walk you through exactly what applies to your chosen gear in your quote.
We fit quality panels, inverters and batteries backed by real manufacturer warranties, the kind we would put on our own homes. The best match depends on your roof and budget, so we recommend specific brands as part of your quote rather than pushing a single package.
Quality panels are built to keep generating for 25 years or more, which is why they carry a 25-year performance warranty. Inverters typically have a shorter life and may need replacing once over the life of the panels, which we factor into the honest payback numbers.
How the job runs
From accepting your quote to switch-on is often a few weeks, depending on grid connection approval and scheduling. The install itself is usually done in a day for a typical home system. We give you a realistic timeline in writing rather than an optimistic guess.
Not very. For a typical home the crew is on site for a day, you may have a short power interruption while they connect the system, and they tidy up before they leave. They will also walk you through your monitoring app so you can see your system working.
You get app monitoring from day one and a clear point of contact with us. We are here for warranty questions, output checks and future upgrades. We do not disappear once the panels are on the roof.
