For a household using 20 kWh a day, about $646 a quarter at Victoria's 30c a unit, the calculator puts 10–13kW solar at $6,270 to $11,270 after rebates, and 10–13kW solar + ~15kWh battery at $9,640 to $20,640. This page also covers Myrtleford.

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 Victorian rates and rebates, and sun hours are its figure for Victoria. Wangaratta's postcode is in Zone 3 of the federal small-scale scheme, which carries a rating about 17% higher than Melbourne's Zone 4[1]. The panel discount on this page is priced for that zone; the sun hours are still the calculator's Victoria-wide figure.
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 Victoria.
| Household uses | Their quarterly bill | System | After rebates | Saves a year | Pays for itself |
|---|---|---|---|---|---|
| 10 kWh | $373 | 5–6.6kW solar | $4,070 to $6,100 | $350–$530 | 9–10+ years |
| 15 kWh | $510 | 6.6kW solar | $4,850 to $6,850 | $500–$750 | 8–10 years |
| 22 kWh | $701 | 10–13kW solar | $6,600 to $11,600 | $760–$1,140 | 7–10+ years |
| 30 kWh | $919 | 10–13kW solar | $6,600 to $11,600 | $990–$1,480 | 6–9 years |
The bill column is what that household actually pays in Victoria 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 1c 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.
Wangaratta is the hub of the north-east, a rural city with valley towns like Myrtleford up the Ovens and a lot of farmland on long rural lines. It is on AusNet's network, its postcode is in the federal scheme's Zone 3, and the property you are on, town block or rural, changes the answer more than anything else.
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. Wangaratta is on AusNet's network[2], so AusNet's rules are the ones a quote here should be designed to. Look for AusNet Services on your bill, near the meter details.
How exports work on AusNet. AusNet's connection policy from 1 July 2026, approved by the Australian Energy Regulator, lets a household system be assessed instantly online for up to 10kW of inverter capacity and 5kW of export per phase, or 3.5kW per phase on a single-wire earth return line, the kind that runs out to a lot of rural properties. Flexible export conditions apply to new connections, so the limit can move with what the local network can take, and an inverter that cannot stay connected to AusNet over the internet falls back to a low static limit[3].
What that means in practice: the limit is set for your address when your installer applies, before anything goes on the roof. Ask to see it before you sign, and ask whether the inverter will stay online for flexible exports. 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 about 1c a unit. So size the array to what the house uses, not to the size of the roof.
At the 2021 Census Wangaratta had 19,214 people and a median age of 44. 24.8% of residents were 65 or older, against 16.8% across Victoria, and 26.8% of homes had four or more bedrooms, against 32.6% statewide.[4]
In town, most jobs are ordinary house roofs. Out of town, the questions are about line type, sheds and distance.
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.
AusNet's online assessment allows 5kW of export per phase on a standard connection and 3.5kW per phase on a single-wire earth return line[3]. Rural properties around Wangaratta and up the valleys can be on lines like that.
On a single-wire line, a big array exports less of its surplus, so more of its value has to come from the house using the power. Find out the line type before sizing anything, and ask whether the inverter can stay online for flexible exports.
In a valley like the Ovens, the sun can clear the hills late and drop behind them early, especially in winter. That cuts the shoulders off a panel's day. A good quote in Myrtleford or Bright models the horizon at your address rather than assuming open sky, and the difference can be large enough to change the size worth buying.
These are examples, not an average for Wangaratta. They are picked to show how the answer moves for the kinds of household the census shows are common here. Clean roof, no shading, Victorian 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 $130 to $390 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. One local difference: this postcode is in Zone 3, where the same system earns about 17% more STCs than in Melbourne[1], and the figure above already counts it.
Up to $1,400, or half the cost after the STC discount if that is less, plus a matching interest-free loan you choose when you apply. Household taxable income under $150,000, property under $3 million, and no solar installed at the address in the last ten years. Owner-occupiers, owners of homes under construction and rental properties can all apply. Rebates are released in batches, so check what is left in the current release before you count on it. From 1 July 2027 household solar support moves into the Victorian Energy Upgrades program[5][6].
Victoria's own battery support has closed, so the federal Cheaper Home Batteries Program is the one that applies[7]. 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]. Larger batteries earn less per extra kWh: the full rate applies to the first 14kWh.
There has been no minimum feed-in tariff in Victoria since 1 July 2025. Retailers set their own, and it cannot go below zero[9]. The calculator assumes 1c a unit, 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, 20 kWh a day, the calculator puts 10–13kW solar at $6,270 to $11,270 after Victorian rebates, and 10–13kW solar + ~15kWh battery at $9,640 to $20,640. 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.
AusNet. It is on AusNet's network, so AusNet sets the export limit for your address when your installer applies, not your retailer. Its policy from 1 July 2026 assesses household systems online for up to 5kW of export per phase, or 3.5kW on rural single-wire lines, with flexible export conditions on new connections. Ask your installer for the approved limit before you sign.
AusNet. AusNet runs zone substations at Wangaratta and Myrtleford. It sets the export limit for your address when your installer applies, not your retailer, so ask for the approved limit before you sign.
Yes, but the hills matter. Where the sun clears a ridge late and drops behind another early, panels lose the start and end of the day, more so in winter. Ask for a design that models the horizon at your address. The worked examples on this page assume a clear roof, so treat them as the upper end for a shaded valley site.
