For a household using 24 kWh a day, about $755 a quarter at NSW's 30c a unit, the calculator puts 10–13kW solar at $7,670 to $12,670 after rebates, and 10–13kW solar + ~15kWh battery at $11,040 to $22,040. This page also covers East Maitland.

See what my home should costA family in a newer four-bedroom house, someone home some days, using 24 kWh a day.
A ballpark for one example household, not a quote. The low end of each range is what a competitive installer charges; the high end is a poor quote for the same equipment. Prices are from the same calculator the free assessment uses, with NSW rates and rebates, and sun hours are its figure for New South Wales.
Four real households, run through the same calculator this site uses for an individual report. Panels only, no battery, clean roof, someone home some of the time. Prices are after every rebate that applies in New South Wales.
| Household uses | Their quarterly bill | System | After rebates | Saves a year | Pays for itself |
|---|---|---|---|---|---|
| 10 kWh | $373 | 5–6.6kW solar | $5,470 to $7,500 | $490–$730 | 9–10+ years |
| 15 kWh | $510 | 6.6kW solar | $6,250 to $8,250 | $650–$970 | 8–10 years |
| 22 kWh | $701 | 10–13kW solar | $8,000 to $13,000 | $1,020–$1,530 | 6–10 years |
| 30 kWh | $919 | 10–13kW solar | $8,000 to $13,000 | $1,230–$1,850 | 5–8 years |
The bill column is what that household actually pays in New South Wales at 30c a unit, which is why the same house has a different bill in every state. Savings depend on how much of the generation gets used on site rather than exported, and at 3.4c a unit for exports that is the number that decides the answer. A household out all day saves less than the figures above; one home most days saves more. Every figure is produced by the calculator, not written down, so it moves when the published rates move.
Maitland is a Hunter city of family houses, parts of which sit on the Hunter River floodplain[1]. For solar it is on Ausgrid's network, the same as Sydney. The local question that other pages do not need to ask is where the battery and inverter go on a property that could flood.
Your retailer sells you the power. Your distributor owns the poles and wires, and it is the distributor that decides how much solar you may send back to the grid. Maitland is inside Ausgrid's network[2], so Ausgrid's rules are the ones a quote here should be designed to. Look for Ausgrid on your bill.
A choice from late 2026. Ausgrid is giving new and upgraded systems a choice. A flexible export connection is automatically approved to export up to 10kW per phase, and Ausgrid can turn it down when the local network needs it, to a minimum of 1.5kW per site. A fixed export connection is approved for 3kW per system and is never adjusted. Either way the inverter has to talk to Ausgrid over the internet; a house without a reliable connection gets a static limit of 1.5kW[3].
What that means in practice: flexible suits a bigger array that will have surplus most afternoons; fixed suits a house that uses most of what it makes and wants a number that never moves. Power the house uses, or a battery stores for the evening, is worth the full import price. Power that runs into the export limit is simply lost, and even what gets out earns only a few cents. So size the array to what the house uses, not to the size of the roof.
At the 2021 Census the Maitland local government area had 90,226 people and a median age of 36. 87.3% of occupied homes were separate houses and 48.1% had four or more bedrooms, against 33.9% across New South Wales. 39.1% were owned with a mortgage.[4]
Mostly family houses, a lot of them newer, on Ausgrid's network[2].
Things worth knowing before an installer walks the roof:
All of that describes the area, not your house. Two homes on the same street can be completely different jobs. Put your address in and the assessment works off the actual property rather than a town average.
Maitland City Council issues flood certificates that say whether a property is known to be flood-affected, the type and extent of the risk, and the planning controls that apply[5]. If your property is on flood-prone land, that certificate is worth having before a battery quote, not after.
Panels on a roof are out of the water. A battery, an inverter and the switchboard work are not, unless someone puts them there. Ask the installer where they plan to mount each piece of equipment, and how that compares with the flood level for your address.
From late 2026, new and upgraded systems on Ausgrid's network choose between a flexible connection of up to 10kW per phase, which Ausgrid can turn down to 1.5kW per site, and a fixed 3kW per system[3]. A family out all day with a mid-sized array exports a lot in the afternoon, so the choice matters.
These are examples, not an average for Maitland. They are picked to show how the answer moves for the kinds of household the census shows are common here. Clean roof, no shading, NSW rates and rebates, and the battery prices assume it is installed before the federal battery discount steps down on 1 January 2027.

Solar plus a 15kWh battery. It pays back fastest of the options open to you, which is the only measure here that accounts for what the thing actually costs.
Before any of it: get onto a competitive retail offer. It costs nothing, it takes an afternoon, and on a bill your size it is worth roughly $150 to $450 a year. Every payback below gets shorter once you are paying less per kWh, so it is worth doing first either way.

"Pays for itself" is the range between a competitive quote and a poor one for the same equipment, and 10+ means not inside ten years. The battery ranges are wide for the same reason. Your own usage, roof and timing will move every figure here, which is what the free assessment works from.
Applied by the installer as a discount on the quote, not something you claim. It scales with system size: on the 10–13kW solar in the first example above the calculator counts $2,330. It falls a little each year until the scheme ends in 2030.
There is no upfront state rebate on solar panels in New South Wales. There is the Home Energy Saver loan: interest-free, up to $15,000, repaid over up to ten years, for property owners, including landlords, with a combined taxable household income up to $210,000. Rooftop solar and batteries are both eligible, and the loans are delivered by Brighte and Plenti[6]. A separate discount of up to $4,000, for households earning up to $80,000 a year or holding an eligible concession card, has been announced but was not yet open on 26 October 2026[7]. The calculator leaves the loan out of every price, because it is repaid.
The federal Cheaper Home Batteries Program applies in NSW. On a 10kWh battery the calculator counts $2,520. The rate is set by the date the battery is installed, not when you order it, and it steps down on 1 January 2027 and every six months after that[8]. NSW's own battery discount under the Peak Demand Reduction Scheme is now only available through approved programs or on government sites, and NSW points battery owners to a separate incentive for joining a virtual power plant[9].
IPART's benchmark for a flat feed-in tariff in 2026-27 is 3.4 to 6.5c a unit, down from 4.8 to 7.3c the year before, and retailers do not have to pay it[10]. The calculator assumes 3.4c a unit, the bottom of that range, which is why every example on this page is decided by how much power the house uses itself.

Already holding a quote? This is how I read one, line by line.
For the first example household on this page, 24 kWh a day, the calculator puts 10–13kW solar at $7,670 to $12,670 after NSW rebates, and 10–13kW solar + ~15kWh battery at $11,040 to $22,040. The range is the gap between a competitive installer and a poor quote for the same equipment. Your own figure depends on your usage and roof, which is what the free assessment works out.
Ausgrid. It sits inside Ausgrid's network, so Ausgrid sets your export limit, not your retailer. From late 2026, new and upgraded systems choose a flexible connection of up to 10kW per phase, which Ausgrid can turn down to 1.5kW per site when it needs to, or a fixed 3kW per system. Ask your installer which they have designed to before you sign.
If your property is on flood-prone land, yes. Maitland City Council issues flood certificates showing whether a property is known to be flood-affected and what controls apply. Ask the installer where the battery and inverter will be mounted, and compare that with the flood level for your address.
