Solar Panel Installation in Sydney: 2026 Costs & Rebates

Solar in Sydney pays for itself faster than most people expect, and the reason starts with one number: the federal STC rebate knocks roughly $1,800 off a 6.6 kW system before you’ve signed anything. There’s no NSW state solar panel rebate to stack on top — that part trips a lot of people up — but the federal discount is the same generous scheme the rest of the country gets, taken straight off the price at the point of sale.

So what does a Sydney install actually cost, and what’s the catch with the new feed-in rates? Here’s the local read from a CEC Approved Retailer that fits panels from the Inner West out to the Central Coast.

How much do solar panels cost in Sydney in 2026?

Installed pricing moves with the size of the system and the state of your switchboard, but the federal rebate is fixed by formula. A standard 6.6 kW system — the size that suits a typical Sydney roof — attracts around $1,800 in small-scale technology certificates (STCs), and that comes off the upfront price rather than landing as a cheque months later. We lodge the certificates; you pay the net figure. We confirm your exact STC value at the quote, since the certificate price shifts a little week to week.

Bigger roofs and bigger bills push toward 10 kW or 13 kW, where the rebate scales up accordingly. The honest framing is this: the discount is meaningful, but it’s the same scheme everyone in Australia accesses. There’s no Sydney-specific top-up, and any installer telling you otherwise is selling something. You can check the program detail yourself on the Clean Energy Regulator site.

Is there a NSW solar rebate on top of the federal one?

No — not for the panels. New South Wales doesn’t run a state solar panel rebate, so the federal STC discount is the whole rebate picture for your array. The state’s energy support has shifted toward batteries instead, through the Peak Demand Reduction Scheme and its Virtual Power Plant incentive, which is a different conversation and only kicks in once you add storage.

That’s worth being clear about, because the Sydney market is noisy with “government rebate” ads that imply a NSW-only cash bonus on solar. There isn’t one. The federal STC scheme is solid and national, and we claim it for you so you never chase paperwork. If you’re weighing up storage later, our guide to the Cheaper Home Batteries Program covers where the battery money actually sits.

How much sun does Sydney get for solar?

Sydney averages about 4.2 peak sun-hours a day across the year — dependable production that sits above Melbourne and a touch below the brightest northern cities. A well-sized 6.6 kW array on a north-facing Sydney roof generates plenty through the day, with strong summer yield and a respectable winter floor.

Orientation matters more than people think here. East-west splits suit a lot of Sydney homes, especially the terraces and semis where a clean north pitch isn’t on offer. We fit plenty of split arrays across the Inner West where the roof simply doesn’t face the right way. You lose a little peak output but gain a longer, flatter generation curve that lines up better with morning and evening use. We size against your actual roof and bill, not a brochure ideal.

What about the Sydney feed-in tariff — is exporting worth it?

This is the part that changes how you should think about a system. New South Wales has no mandated minimum feed-in tariff. IPART, the state pricing regulator, publishes a benchmark each year, but retailers set their own rates, and in 2026 those have settled into the low single digits per kWh. Buying power back during the evening peak runs far higher. So every unit of midday solar you export earns you a few cents; the same unit, bought back at night, costs many times that.

What that means for a new Sydney system: build it to use your own power, not to sell it. Run the dishwasher, the pool pump and the hot water in the middle of the day while the panels are pumping, and you’re spending those cheap solar units instead of exporting them for a pittance. It’s also the strongest argument for adding a battery later — store the surplus rather than give it away. We dig into sizing in our solar sizing guide.

The rebate is the discount, not the sticker price, and it scales with system size. We confirm your exact figure at the quote against a recent bill.

Which Sydney network am I on — Ausgrid, Endeavour or Essential?

Sydney is split across three distribution networks, and which one you’re on decides the connection rules for your solar. Most of the Sydney metro — the Inner West, the Eastern Suburbs, the lower North Shore and the city — sits under Ausgrid. The greater west and south-west, out through the growth suburbs, falls under Endeavour Energy. Essential Energy covers regional NSW and the fringes beyond the metro. Each has its own application process and its own export limits, and getting the paperwork right the first time is the difference between switching on in days versus chasing a knockback for weeks.

We handle the network application as part of every install, and we know which way each operator leans on things like export caps and inverter approvals. That’s the quiet value of using a team that fits systems across all three networks day in, day out.

Which Sydney regions does eHomes cover?

Across the lot. Day to day we’re fitting solar through the Inner West, the North Shore, the Eastern Suburbs, the Hills and the Sutherland Shire, and we head out to the Central Coast, Newcastle and Wollongong regularly. A recent Sutherland Shire job is a good example of the local picture: a 1960s brick home with a cramped switchboard and an east-west roof. We split a 6.6 kW array across both pitches, upgraded the board to meet the Ausgrid connection rules, and had the family generating within the week. No drama, no surprise costs on the day — we’d scoped it properly at the quote.

Whether you’re in a Paddington terrace or a Wollongong family home, the panels we fit come from a Tier-1, CEC-approved shortlist — JA Solar, LONGi, Risen and TopCon N-type — backed by a 25-year performance warranty plus our own 10-year workmanship warranty. The full service detail sits on our solar panels page and the local rundown on our Sydney solar page.
