The short answer for 2026: a 6.6kW rooftop solar system in Victoria typically costs around $5,000 to $9,000 installed after the federal panel rebate, and on top of that Solar Victoria has historically run its own Solar Homes offer for eligible households. The federal discounts apply automatically at the point of sale, the state offer does not, so the single most important thing you can do is confirm what Solar Victoria is offering this year before you sign anything.
That is the catch with Victoria. The federal layer is stable, but the state layer moves around, and the headlines you half remember from a few years ago may not match what is open today. Here is the full 2026 picture, all figures last checked June 2026 and quoted as ranges because solar pricing and government schemes both shift often.
What you actually pay for solar in Victoria in 2026
Solar pricing in Victoria is broadly in line with the rest of the mainland. The state has a deep, competitive installer market, so prices here are no worse than the national average. The numbers below are typical installed prices after the federal panel rebate.
| System | Typical Victorian price in 2026 (after federal rebate) | Notes |
|---|---|---|
| 6.6kW panels only | ~$5,000 to $9,000 | The standard starting point for most homes |
| 10kW panels only | ~$8,000 to $13,000 | Larger roofs, bigger households, more daytime load |
| 10kWh battery (added) | ~$6,500 to $9,500 | Price after the federal battery rebate |
Treat these as ranges, not quotes. The spread inside each row comes down to component quality, roof complexity, switchboard upgrades, and how hungry the installer is that month: a simple single-storey tin roof sits at the cheap end, a double-storey tile roof with an old board at the top. For the full national breakdown, our guide to solar panel cost in Australia walks through what drives the price line by line.
The federal rebates apply in Victoria automatically
Before anything Victoria-specific, you get the two federal discounts every household in the country qualifies for. Both are claimed by your accredited installer and shown as a discount on the quote rather than money you chase later, and they are already baked into the prices above.
The STC discount on panels
The federal small-scale technology certificate scheme, the STC rebate, has discounted rooftop panels since 2011 and is the reason solar is cheap in Australia at all. In 2025 it was worth roughly $2,200 to $2,800 on a 6.6kW system. The wrinkle: it steps down a little every year and is legislated to phase out by 2030, so the dollar value quietly shrinks each January you wait.
The battery discount
Since 1 July 2025 the federal Cheaper Home Batteries Program has knocked roughly 30 per cent off the installed price of a home battery, around $330 per kWh of usable capacity in 2025, through the same certificate plumbing as the panel rebate. Like the STC scheme it winds down toward 2030. That discount is already reflected in the battery row above, and our solar battery cost in Australia guide covers how the maths plays out once you add storage.
Where Solar Victoria fits
This is the part worth slowing down for. Solar Victoria runs the state’s Solar Homes Program, and historically that program has offered Victorian households a rebate on solar panels, an interest-free loan to spread the rest of the cost, and a separate loan toward a battery. The exact mechanisms, the amounts, and crucially whether any given component is open at all have changed from year to year.
So rather than quote a figure that may already be stale, here is the honest version: the mechanism is a state rebate and a state loan, sitting on top of the federal discounts, aimed at owner-occupiers who meet the eligibility tests. Those tests have historically included a household income cap and a property value cap, with the property usually needing to be your home rather than an investment. Whether the panel rebate is open, whether the loans are available, and what the caps are this year are all things to confirm directly with Solar Victoria before you budget for them.
The federal rebate is on your quote whether you ask or not. The Victorian one is only yours if you check that it is open and that you qualify before you sign.
Why the caveat matters more here than elsewhere
State solar schemes are genuinely volatile: they run to budgets and quotas, get paused and reopened, and tighten or loosen between financial years. An installer quoting a state rebate from memory is not a reliable source. Solar Victoria itself is, and the check there can be worth several hundred to a few thousand dollars.

The Victorian feed-in tariff in 2026
Once running, the power you export earns a feed-in tariff. Victoria is one of the few states with a regulated minimum, set each year by the Essential Services Commission, so retailers cannot pay below the floor. The catch is that the floor has fallen a long way: feed-in tariffs nationally are now only a few cents per kilowatt hour, and Victoria’s regulated minimum has dropped into the low single-digit cents range to match. Last checked June 2026, do not build your business case on export income.
The takeaway has not changed in a couple of years: the money in solar now comes from the power you stop buying, not the trickle you sell back. That is why batteries and daytime load shifting have become the centre of the conversation.
Does Victorian sunshine stack up
Yes, with one honest caveat. Victoria sits further south than Queensland or New South Wales, so output per kilowatt is solid but lower than the sunbelt states, and the gap is widest in winter. A well-sited Melbourne system still produces plenty across the year, it just leans harder on summer. Face panels north where you can, do not undersize, and if winter self-sufficiency matters, size for it rather than the brochure’s annual average.
The installer point, which matters everywhere
One number should worry you more than the rebate amounts: more than 700 solar retailers have gone under in Australia since 2011, and roughly one in six installed systems is now effectively orphaned, meaning the company that fitted it no longer exists to honour the warranty. A ten-year warranty is worth nothing from a business that folds in year three.
So weigh installer longevity as heavily as price. Favour an established local Victorian operator with a real trading history over the cheapest quote from a name you cannot verify, and get multiple quotes so you can see where the market sits. It is worth taking the time to compare quotes from accredited Victorian installers before you commit, so the price and the company both stack up.
The bottom line
In 2026 a Victorian household gets a stable federal discount on panels worth roughly $2,200 to $2,800 on a 6.6kW system, a federal battery discount of about 30 per cent, and potentially a Solar Victoria offer on top, with that 6.6kW system landing around $5,000 to $9,000 installed after the federal rebate. The federal layer is automatic and the state layer is not, so confirm the current Solar Victoria offer and your eligibility before you budget for it. Expect only a few cents per kilowatt hour from the feed-in tariff, plan your savings around the power you stop buying, and choose an installer who will still exist when you need the warranty.
