Solar in rural Victoria: export limits, single-wire lines and rebates
Solar on a farm, a lifestyle block or a country town house works differently from the suburbs. The network, the line to your property and even your postcode change what you can export and what you pay.
The short answer
- Your network decides your export limit: most rural Victorians are on Powercor or AusNet. Your bill says which.
- Single-wire (SWER) lines get a lower export limit and are assessed case by case.
- Northern Victoria gets more federal rebate: about $2,040 on a typical system, against $1,750 in Melbourne.
Which network you're on
Two networks carry most of country Victoria's power. Powercor's area takes in Geelong and the Bellarine[1]; AusNet's takes in towns such as Wangaratta, Wodonga, Bairnsdale, Sale and Warragul[2]. Your bill names your distributor.
- Powercor: lowering the maximum fixed export limit to 1.5kW per phase over 2026 to 2031, with flexible exports of up to 10kW per phase where the network allows[3].
- AusNet: online approval up to 5kW export per phase on most lines, unless a flexible limit applies[4].
Single-wire lines are different
Many farms and remote homes are fed by a single-wire earth return (SWER) line. On AusNet, a SWER connection is limited to under 3.5kW of export per phase, against under 5kW on other lines, and is assessed case by case[4]. Ask your installer to check before they size a system.
The northern Victoria rebate bonus
The federal solar discount (STCs) depends on your postcode's zone. Postcodes from 3340 to 3758, which take in much of central and northern Victoria, are in a sunnier zone than Melbourne and Gippsland[5]. On our calculator that is about $2,040 off a typical system there, against $1,750 in Melbourne[6].
On top of that, Solar Victoria's rebate takes up to $1,400 off, or half the cost after STCs if that is less, for eligible households. Solar support moves into the Victorian Energy Upgrades program from 1 July 2027[7].
Why a battery matters more in the country
With a 1.5kW export limit, a big array sends little to the grid on a sunny day, so storing the surplus in a battery is worth more. And where outages are common, a battery set up for backup can keep the essentials running[8]. Tell your installer at the start if you need backup[9].
What to ask before you buy
- What export limit did my pre-approval come back with, and is it fixed or flexible?
- Am I on a SWER line?
- Is my internet good enough for flexible exports?
- Does the design include backup, and for which circuits?
Why two quotes for the same job can be thousands apart
Installers price the same system very differently. These are the installed price ranges our calculator works from, before rebates: the low end is what a competitive installer charges, and the high end is what a poor quote looks like.
| System | Competitive quote | Poor quote |
|---|---|---|
| 6.6kW solar system | $8,000 | $10,000 |
| 10kWh battery | $7,650 | $13,500 |
| About 15kWh battery | $12,100 | $18,000 |
- The gap usually comes from margin, the brand of panel, inverter or battery, and extras such as a switchboard upgrade or backup circuit, not from a better install.
- Get at least two or three quotes, and ask for each to be itemised: hardware brands and models, size, rebates taken off, and anything extra.
- Compare batteries on price per usable kWh, not the headline price.

What is the solar export limit in rural Victoria?
It depends on your network. Powercor is moving to a 1.5kW per phase fixed limit with flexible exports up to 10kW. AusNet approves up to 5kW per phase online, or under 3.5kW on a single-wire line.
Do rural Victorians get a bigger solar rebate?
In much of central and northern Victoria, yes: those postcodes are in a sunnier zone, so the federal STC discount is larger.
Is a battery worth it on a farm?
Often more than in the city, because export limits are tighter and outages more common. It depends on your evening use.
