Is solar still worth it in 2026? The honest answer.
Mostly yes — but let's start with who it's NOT worth it for, because no seller will. Solar remains one of the best returns going for the right roof and the right usage. For some homes, the honest advice is to wait or go smaller. No sales "yes", just the real verdict.

Who is solar
NOT worth it for?
Solar is worth it for most Australian homes — but not all, and that's the part sellers skip. Before the "yes", here's the honest list of who should wait, fix something first, or go smaller.
Almost every site selling solar answers "is it worth it?" with an unqualified yes. We won't, because for a handful of households the real answer is no — or not yet. Naming them up front is the honest thing to do, and it's the answer no lead-funnel gives you.
Solar usually isn't worth it (yet) if:
- You're out all day and use almost nothing at home while the sun is up, and you'd export nearly everything for a small feed-in tariff. With export credits now low, exported-only solar barely pays.
- Your roof is small, heavily shaded, or faces mostly south, so it will never produce much. Trees, a tight roof, or bad orientation can quietly halve the output the salesperson quotes.
- You're planning to move within a couple of years. You may not recoup the cost before you sell, and the value it adds to a sale price is uncertain.
- Your electricity use is already very low. If there's barely a bill to offset, there's barely a saving to earn back the system.
If that's you, the honest move is to wait, sort the shading or usage first, or fit a smaller system sized to what you'll genuinely self-consume. For everyone else — most homes with a real daytime load and a decent roof — solar is very likely still worth it in 2026, and the rest of this page explains exactly why and how the numbers fall out.

So is solar still
worth it in 2026?
For most homes, yes — solar remains one of the best returns you can get on your roof. The rebate still helps, but the value has shifted from exporting power to using your own. It comes down to your usage, not a blanket "yes" or a scare-story "no".
Here's the plain verdict: if you have a decent roof and you use real power at home during daylight hours, rooftop solar is still very likely worth it in 2026 — often one of the highest-return upgrades a household can make. The federal STC rebate still takes a meaningful slice off the upfront price, and once the panels are on the roof the electricity they make in the middle of the day is effectively free.
What's genuinely changed is where the value comes from. Feed-in tariffs — the credit you're paid for exporting solar — have fallen a long way, so the old model of "export everything and get paid" no longer works. The money is now in self-consumption: using your own solar as it's generated, instead of buying that power from the grid at full retail price. That single shift decides most of the "worth it or not" question, and it's why the households above (out all day, low usage) are the ones for whom solar struggles.

What actually decides
whether solar pays for you?
Five things decide it — and none of them is the number of stars on the brochure. Solar pays when your roof, your usage pattern and your prices line up so it displaces power you'd otherwise buy in the day.
Your daytime usage
Solar pays most on the power you use while it's being made. A household with real daytime load — someone home, appliances running, an EV or hot water shifted to daylight hours — self-consumes more, and self-consumption is where the savings now sit.
Your roof
Size, pitch, orientation and shade set the ceiling on output. A clear, north-facing roof produces far more than a small, shaded or south-facing one. This is the single factor a good installer should check honestly before quoting anything.
Your feed-in tariff
The credit for exported solar has fallen across the country, so exporting no longer earns much. The lower your feed-in tariff, the more it pays to use your own solar rather than sell it — which tilts the maths toward self-consumption.
Your electricity rate
The more you pay per kilowatt-hour from the grid, the more every unit of solar you self-consume is worth. High or rising retail rates strengthen the case for solar; a very cheap tariff weakens it.
Price after the rebate
The federal STC rebate still takes a real chunk off the upfront cost, which shortens payback. It's smaller than a couple of years ago, but far from gone — and it's automatic at the point of sale, not a form you chase.
Who installs it
A cheap system from a seller that won't be around in three years is a false economy. The panels, the workmanship and the after-sales support all matter — more on the "orphaned system" risk below.
How much does a 6.6kW system
cost after the rebate?
There's no single sticker price — the installed cost depends on your panels and inverter, your roof and switchboard, and the STC rebate you qualify for. The federal STC rebate is the big one, and it's still worth a meaningful amount.
The federal rebate is delivered as tradeable STCs (small-scale technology certificates), applied automatically as a discount at the point of sale rather than a form you claim later. For a typical 6.6kW system in most metro postcodes (Zone 3), that's worth roughly $1,700 to $1,900 as at 2026 — with the exact figure floating with the STC market (around $37 to $39 per certificate) and varying by your postcode zone and the price on the day you install. (Source: Clean Energy Regulator, cer.gov.au.)
Two honest points that cut against the usual sales pressure:
- The rebate did shrink a little — but not off a cliff. From 1 January 2026 the certificates are calculated over a shorter deeming period, which trimmed the STC value for a 6.6kW system by roughly $300 to $400 compared with before. That's a real change worth knowing, but it's a modest step-down, not the collapse some headlines implied.
- We won't quote you a fixed dollar figure here. Because the STC value floats with the market and the total depends on your exact system, roof and site, any headline "$X after rebate" number you see online is an estimate that drifts. The honest way to compare is a real quote for your home.

Why is my power bill
still high after getting solar?
Because "buy more panels" is rarely the answer. Three things keep a bill high even with a good system — the fixed supply charge, the fall in feed-in tariffs, and when you actually use your power.
This is one of the most common — and most misunderstood — questions we hear. People fit solar, watch the meter spin backwards during the day, and are surprised the bill doesn't vanish. Here's the honest breakdown of what's still on it:
- The fixed daily supply charge. You pay this every day just to stay connected to the grid, even if your usage nets to zero. Solar reduces the energy you buy, but it doesn't remove this standing charge — so there's always a floor under the bill.
- The fall in feed-in tariffs. The credit for exported solar is now small right across the country. If your system exports a lot at midday, those exports no longer move the bill much — which is exactly why the value has shifted to self-consumption.
- When you use your power. If most of your usage lands in the evening and overnight — after the panels stop producing — you're still buying that energy from the grid at full retail rate. Solar can't offset power you use in the dark.
The honest fix usually isn't more panels — it's shifting usage into daylight hours (run the dishwasher, washing, pool pump or EV charging while the sun's up), and only if the numbers support it, considering a battery to store daytime solar for the evening. Whether a battery actually pays for you is its own question — we walk through it honestly in is a home battery worth it in 2026. A free assessment will read your real bill and show you which of these three is driving your cost.
What is the sun tax, and will it
make solar pointless?
No — it won't make solar pointless, and for a typical home the dollar impact is small. Two-way export pricing changes the maths on oversizing and exporting at midday, not the core case for solar.
The "sun tax" is the nickname for two-way export pricing: a network charge for exporting solar to the grid during the sunny middle of the day, when the grid is already awash with rooftop solar and doesn't need more. It's live in New South Wales and South Australia as at 2026. VIC and QLD homes are not on it as things stand — but always confirm your own network's rules.
Two things keep it in proportion, honestly:
- It's a charge on retailers, not a line item you automatically see. The network levies it on your retailer, so you only feel it if and how your retailer chooses to pass it through. For a typical household the net effect is minor, and it's often paired with a reward for exporting during the evening peak, when the grid actually wants your power.
- It's a reason to size sensibly, not to skip solar. What the sun tax really changes is the value of dumping huge amounts of solar to the grid at midday — which is worth less than it used to be. That's another nudge toward self-consumption: designing a system around the power you'll use, rather than the biggest array that will fit.
If you're in a sun-tax state, it's a factor to design around — the sort of thing a good assessment builds into the sizing. See the state-specific detail on our New South Wales page, and the broader picture on solar systems.
What happens to my warranty
if my installer goes bust?
You don't automatically lose everything — the manufacturer's product warranty generally survives. What you lose is the installer's workmanship warranty and after-sales support, which is why who you buy from matters as much as what you buy.
There's a lot of fear about this, so let's be precise. If your installer stops trading, the manufacturer's product warranty on your panels and inverter generally survives and can usually be claimed directly with the maker or importer, provided they're still trading in Australia. What you lose is the installer's own workmanship warranty and after-sales service — the company that would have come back to fix a fault, handle a return or answer the phone in year six.
That matters more than most buyers realise. An estimated 600,000 Australian solar systems are "orphaned" (roughly 1 in 6 to 7) — meaning the company that sold them has since stopped trading — an industry estimate by Markus Lambert, reported by CHOICE. So the long headline warranty on a panel is only as good as the business that has to stand behind the install.
The honest takeaways aren't "fear solar" — they're two practical rules:
- Choose an installer likely to still be around. A rock-bottom price from a seller that may not survive the decade is a false economy. Before you pay a deposit, it's worth a quick check on who you're buying from — our forthcoming guide to checking a solar installer before you pay a deposit walks through how.
- Avoid cheap no-name panels — but "Chinese" isn't the problem. The real risk is sub-quality, obscure-brand hardware from a seller that won't last. The reliable Tier-1 makers most quality installers use — LONGi, Jinko, Trina, JA Solar — are themselves Chinese and thoroughly proven. The line to draw is quality and support, not country of origin. See the brands we install on our solar systems page and our own warranty terms.
What size and setup
is right for you?
There's no universal "best" system — the right size depends on your daytime usage, your roof and whether a battery or EV is on the horizon. Once you've decided solar is worth it, here's where to work out the specifics.
Size it to your usage
Bigger isn't automatically better now that exports pay little. See how payback actually works, and what size self-consumes best, in our solar payback guide for 2026 — and compare systems side by side on our compare tool.
Where you live matters
Sun hours, tariffs and local rules differ by city. Read the local detail for solar in Melbourne or solar in Sydney, or the full state picture for Victoria and New South Wales.
Solar, then maybe battery
Solar almost always comes first — a battery has nothing cheap to store without it. If you're weighing storage too, get the honest verdict in is a home battery worth it in 2026, and see the solar systems and rebates we cover.
So — should you get solar?
Here's the recommendation we'd actually give a friend: for most homes, yes — but get your numbers run before you spend a cent, and be open to hearing "smaller" or "wait".
If you have a decent roof and real daytime usage, rooftop solar is very likely worth it for you in 2026 — one of the better returns you can get, and the rebate makes today a reasonable time to act. If you're out all day, your roof is small or shaded, you're about to move, or your usage is already tiny, the honest answer is to wait, fix that first, or fit a smaller system sized to what you'll self-consume. Most people sit firmly in the "yes" camp — but the only way to know which side of the line you're on is to run your actual usage and your actual roof, not a brochure average.
Is solar worth it?
Your questions, answered.
For most homes with a decent roof and daytime electricity use, yes — rooftop solar is still one of the better returns you can get, and it is usually worth it in 2026. The federal STC rebate still knocks a meaningful chunk off the upfront price (a typical 6.6kW system attracts roughly $1,700 to $1,900 in STCs in most metro postcodes, as at 2026, with the exact value floating with the market — confirm at quote). What has changed is where the value comes from: feed-in tariffs have fallen a long way, so the money is now in self-consumption — using your own solar during the day — rather than exporting it for a few cents. That means solar is not worth it for everyone. It is a weak buy if you are out all day and use almost nothing at home when the sun is up, if your roof is heavily shaded or faces the wrong way, or if you are about to move. A free Mission Green assessment will run your actual usage and tell you honestly whether solar pays for you, or whether waiting or a smaller system makes more sense.
Solar is usually worth it, but it genuinely is not worth it for some households — and no seller likes to say who. It tends not to pay if you are out all day and use very little power at home while the sun is up, and you would export nearly everything for a low feed-in tariff. It is a weak buy if your roof is small, heavily shaded, or faces mostly south, so it never produces much. It rarely pays if you are planning to move within a couple of years, since you may not recoup the cost before you sell. And it is marginal if your electricity use is already very low, because there is little bill to offset. In those cases the honest answer is to wait, fix the usage or shading first, or fit a smaller system sized to what you will actually self-consume. If you are in one of those groups, we will tell you rather than sell you panels that sit idle.
There is no single sticker price, because the installed cost depends on your panels and inverter, your roof and switchboard, and the STC rebate you qualify for.

From 1 January 2026 the certificates are calculated over a shorter deeming period, which trimmed the rebate by roughly $300 to $400 compared with before — a real change, but not the collapse some headlines suggested. Because the certificate value drifts and depends on your exact system, the honest way to compare is a free, no-obligation assessment where Mission Green quotes your options for your home and tells you if a smaller system, or waiting, makes more sense.
This is one of the most common questions we get, and the answer is usually not 'buy more panels'. Three things keep a bill high even with a good solar system. First, the fixed daily supply charge: you pay this every day just to be connected to the grid, even if your usage nets to zero, so it never disappears with solar alone. Second, the fall in feed-in tariffs: the credit you get for exported solar is now small, so exporting a lot no longer moves your bill much. Third, usage behaviour: if most of your power is used in the evening and overnight when the panels are not producing, you are still buying that energy from the grid at full price. The fix is to shift usage into daylight hours where you can, and — only if your numbers support it — consider a battery to store daytime solar for the evening. A free assessment will read your actual bill and show you which of these is driving your cost, rather than guessing.
No — the sun tax does not make solar pointless, and its dollar impact for a typical home is small. The sun tax is two-way export pricing: a network charge for exporting solar to the grid during the sunny middle of the day, when the grid is already flooded with solar. It is live in New South Wales and South Australia as at 2026, and it is a charge on retailers, so you only feel it if and how your retailer passes it through. For a typical household the net effect is minor, and it is often paired with a reward for exporting in the evening peak. What it really changes is the maths on oversizing: sending huge amounts of solar to the grid at midday is worth less than it used to be, which is another reason the value now sits in self-consumption — using your own power during the day — rather than export. It is a factor to size around, not a reason to skip solar.
You do not automatically lose everything, and it is worth being precise about what changes. If your installer stops trading, the manufacturer's product warranty on your panels and inverter generally survives and can usually be claimed directly with the maker or importer, provided they are still trading in Australia. What you lose is the installer's own workmanship warranty and their after-sales service — the company that would have come back to fix a fault or handle a return. This matters because an estimated 600,000 Australian solar systems are 'orphaned' (roughly 1 in 6 to 7), meaning the company that sold them has since stopped trading — an industry estimate by Markus Lambert reported by CHOICE. The lesson is not to fear the technology but to choose an installer likely to still be around, and to avoid cheap no-name panels from sellers that may not last.
