Solar panels in Ballarat

Ballarat is cold, high and sunnier than its reputation. Sitting more than four hundred metres above sea level on the Central Highlands, it gets frosts through winter and the occasional dusting of snow, but it also gets long, clear summer days that make solar work well. The Clean Energy Regulator's postcode data on this page covers the city proper, Wendouree and Lake Gardens, Sebastopol and Delacombe, Buninyong, and the ring of small towns that share Ballarat's postcodes.

Where the installs are going

The growth is on the western edge. Lucas, Alfredton and Winter Valley have been the busiest suburbs for new installs, and they are mostly new estates where the roof, the switchboard and the three-phase supply are all ready. The heritage core around the central grid and Ballarat East installs more slowly, partly because of heritage overlays and partly because older slate and tile roofs need more care.

Roofs and homes in Ballarat

Heritage is the local consideration. A great deal of central Ballarat sits under heritage overlays, and while solar is generally permitted, panels visible from the street can require a planning permit and a layout that keeps them off the front roof plane. Ask an installer who has done heritage work in Ballarat before, because the process is routine for them and painful for someone doing it for the first time. Frost and snow load are a minor concern for mounting; a bigger one is hail, which the region gets often enough that panel impact ratings are worth reading.

The network: Powercor

Powercor runs the network. Single-phase homes generally export up to 5 kW, three-phase homes more, and the flexible export arrangements Powercor has been introducing can lift that in some areas. Winter matters more here than in most of Australia: a Ballarat home that heats with reverse-cycle air conditioning uses its power in the dark, cold months when the array produces least. That is the argument for a battery in Ballarat, and also the argument for not oversizing the battery, because in June there is not much surplus to store.

What a system generates in Ballarat

Ballarat averages 4.3 peak sun hours a day and sits in STC Zone 3. A peak sun hour is an hour of sunlight at full strength, so the figure is what a panel collects once the weaker morning and evening light is added up. On that average, this is what the two most common system sizes produce on a north-facing roof with no shade.

Average daily and yearly solar generation in Ballarat
SystemAverage dayYear
6.6 kW24.1 kWh8,805 kWh
10 kW36.6 kWh13,341 kWh

Worked as system size times 4.3 peak sun hours times 85%, the allowance our suburb pages make for inverter, heat and wiring losses, over 365 average days. Summer days produce well above the average and winter days well below it, and an east or west-facing array produces less than a north-facing one.

Across the eight capitals, the same 6.6 kW system makes from about 7,576 kWh a year in Hobart to about 11,262 kWh in Darwin. In Ballarat it makes about 5% more than it would in Melbourne. More sun means more output from the same panels, but it does not change the STC rebate within a zone: that is set by the zone, the system size and the year you install.

How much solar panels cost in Ballarat

These are the installed prices our solar panel cost guide works on, with the federal STC rebate for Ballarat taken off. The rebate comes off the quote at the point of sale, so the last column is what you actually pay. In STC Zone 3 it is worth $1,710 on a 6.6 kW system and $2,622 on a 10 kW one.

Prices are the national ranges from our solar panel cost guide. Installed prices are before any rebate. The STC rebate is the certificates each system creates in Zone 3 over the 2026 deeming period of 5 years, at $38 a certificate. The deeming period shortens by a year every 1 January, so the same system earns less rebate each year you wait.

Victoria adds to it: eligible households can take a further $1,400 off through the VIC Solar Homes rebate (owner-occupiers and rental providers, subject to the program’s income and property value tests). The table leaves it out because not every household qualifies.

The average system installed across Ballarat in the 12 months to October 2026 was 9 kW, between the 6.6 kW and 10 kW rows, although that average includes some business systems. Size yours on your own bills and roof, but it is a fair check on what your neighbours are putting up.

What moves a quote up or down: the panel and inverter brands, a second storey or a steep or tiled roof, and switchboard or meter work. The full breakdown is in our solar panel cost guide.

Payback in Ballarat

Payback is the after-rebate price divided by what the system saves each year. The saving comes from two places: the power you use yourself, which you no longer buy at around 28.0c per kWh, and the power you export, which earns the feed-in tariff.

    2.4 to 4.2 years

Assumes 30% of the solar is used in the home at 28.0c per kWh, the average residential usage rate we hold for Victoria, and the other 70% is exported at 12.0c per kWh, the best single-rate feed-in tariff we can find for postcode 3350 (Origin Energy). That 30% is the share our suburb pages and calculators assume for a household out at work during the day. No battery, no price rises and no panel ageing are counted.

Using more of it yourself improves the numbers quickly, because a kWh used at home is worth 28.0c and an exported one 12.0c. At 50% self-consumption, which a household home through the day or one that runs the pool pump, dishwasher and hot water on a timer can reach, the 6.6 kW system saves about $1,761 a year in Ballarat and pays back in 2.2 to 3.6 years.

Batteries in Ballarat

The federal Cheaper Home Batteries rebate applies in Ballarat as it does everywhere. It is paid on usable capacity, at $258/kWh for the first 14 kWh and at lower rates above that, and like the STC rebate it comes off the price at the point of sale. It steps down on 1 January 2027, when the full rate falls to $217/kWh.

Battery rebates in Ballarat
Battery (usable)Federal rebate
10 kWh$2,584
14 kWh$3,610

The table is the federal rebate only: there is no VIC battery rebate that a typical household can count on.

Victoria: $1,400 on panels through Solar Victoria for eligible households. The battery loan program has closed.

Whether a battery pays in Ballarat comes down to the gap between what you pay for power and what you are paid for exporting it. Each kWh a battery moves from export into your evening is worth about 16.0c (28.0c less 12.0c). A 10 kWh battery that filled and emptied every day would be worth up to $584 a year on that gap alone; most do less in winter, when there is less surplus to store.

Battery prices by size, before and after the federal rebate, are in our battery cost guide, and the VIC battery rebate page has the state detail.

What Ballarat homeowners ask us

Ballarat homeowners ask whether solar is worth it in a cold climate, and the answer is that panels are more efficient cold than hot; it is the shorter, cloudier winter days that cost you, not the temperature. They ask about Solar Victoria's panel rebate, which is worth checking for current allocation before you rely on it. And they ask about installers, because the region has had its share of companies that appeared during a rebate rush and vanished afterwards. Check the ABN, check the accreditation, and ask for local references you can call.

Questions people ask

How many homes in Ballarat installed solar in the last 12 months?
845 small-scale solar systems were installed across Ballarat's 5 postcodes in the 12 months to October 2026, averaging 9 kW. The figures are the Clean Energy Regulator's postcode data, not estimates.
What solar rebates apply in Ballarat?
Up to $8,000+ in solar and battery rebates apply in Ballarat, calculated from STC Zone 3 and the federal battery rebate. Victoria: $1,400 on panels through Solar Victoria for eligible households. The battery loan program has closed.
What is the best feed-in tariff in Ballarat?
The best single-rate feed-in tariff we can find for 3350 is 12.0c per kWh with Origin Energy. Rates change often; compare plans once your system is in.
How much does it cost to install solar panels in Ballarat?
A 6.6 kW system in Ballarat costs about $5,500 to $8,000 installed. The federal STC rebate in Zone 3 takes $1,710 off, so you pay about $3,790 to $6,290. A 10 kW system is $8,000 to $12,000 before the rebate and $5,378 to $9,378 after it. Eligible households can take a further $1,400 off through the VIC Solar Homes rebate. Prices move with the panels, the inverter, the roof and any switchboard work.
Is it worth getting solar in Ballarat?
For most owner-occupiers with a roof that gets sun, yes. A 6.6 kW system in Ballarat makes about 8,805 kWh a year from 4.3 peak sun hours a day. Using 30% of that at home and exporting the rest saves about $1,479 a year at today's rates, which pays back the after-rebate price in 2.6 to 4.3 years. It pays back faster if you use more of the power during the day, and more slowly on a shaded roof or a small bill.
Who is the best solar installer in Ballarat?
There is no single best installer for every home. Look for SAA accreditation, a written workmanship warranty and a company that has traded under the same ABN for years; our national installer directory lists accredited installers with reviews. If you check your rebate with us, you are matched with one Why Solar Approved installer in Ballarat who has passed all six of our checks.
What is the 20% rule for solar?
It is the rule of thumb that the panels should be rated 20 to 33 per cent above the inverter, such as 6.6 kW of panels on a 5 kW inverter. Panels rarely produce their full rating, so a slightly larger array keeps the inverter working near its capacity for more of the day. The Clean Energy Council's design guidelines, which the STC rules follow, allow panels up to a third larger than the inverter. That is why 6.6 kW is the standard size on a 5 kW inverter, and why 13.3 kW is the largest array on a 10 kW single-phase inverter.
