Farm and business solar around Warragul
Farm solar around Warragul for dairy sheds, pumps and small businesses: three phase connection, AusNet limits above 30 kW, STC eligibility and batteries.
Farm and business solar around Warragul suits properties that use most of their power during daylight, such as dairy sheds, irrigation and stock water pumps, cool rooms, workshops and shops. Systems up to 30 kW on a three phase supply can usually go through AusNet’s standard pre-approval, while larger systems need a paid manual assessment. Federal STCs now apply to systems up to 1 MW, and businesses can also get the federal battery discount.

Why does solar suit farms and businesses in Baw Baw?
The Warragul district is known for dairy farming, and dairying is the principal industry around nearby Darnum, which has a milk processing plant just north of town. Dairy and other farm operations run equipment while the sun is up: milking machines, vacuum pumps, milk cooling, hot water for wash-down, and pumps for stock water and irrigation. Shops, cafes, workshops and small factories in Warragul, Drouin and Yarragon run lighting, refrigeration and machinery through business hours.
That daytime pattern matters. Solar power used on site as it is generated is worth more to the business than power exported to the grid, because retailers set their own feed-in rates and Victoria no longer has a regulated minimum. A business that can soak up most of its own generation gets the most out of each panel.
We do not publish typical farm load figures here because every property is different. Your provider should work from your interval data or a year of bills, not a rule of thumb.
What size system and connection does a farm or business need?
| System size | Typical sites | Network process with AusNet |
|---|---|---|
| Up to 10 kW inverter per phase | Small shop, home office, single phase shed | Automatic pre-approval band with export limit |
| Up to 30 kW across three phases | Workshop, cafe, small dairy, larger shed | Standard process, up to 15 kW export across three phases |
| Above 30 kW, or above 10 kW per phase | Larger dairies, cool stores, factories | Paid manual assessment by AusNet |
| 100 kW to 1 MW | Large farm or commercial roof | Manual assessment; mid-scale STC rules apply |
AusNet’s up to 30 kW connection page sets these limits on combined solar and battery inverter capacity, not panel wattage. A request above the pre-approved offer, above 10 kW on any phase, or using generation other than solar without a battery goes to a paid manual assessment. Export limits depend on substation capacity at the time of application, so a neighbour’s approval does not tell you what yours will be. The AusNet connection guide covers backstop and export rules in more depth.
Do farm and business systems still get STCs?
Yes, and the ceiling has moved. The Clean Energy Regulator says the Small-scale Renewable Energy Scheme now covers eligible solar PV systems from 100 kW to 1 MW, for mid-scale systems installed from 1 October 2026. Before that change, systems above 100 kW sat outside the small-scale scheme.
The Clean Energy Regulator rooftop solar page also notes that an accredited designer is not required for mid-scale systems from 100 kW to 1 MW. Installers must still hold Solar Accreditation Australia accreditation and an unrestricted electrical licence, attend the site at set-up, mid-installation and commissioning, and use modules and inverters from the Clean Energy Council approved lists.
Can a business get the federal battery discount?
The Department of Climate Change, Energy, the Environment and Water says Australian households, businesses and community organisations can get a discount of around 30 percent on the upfront cost of installing small-scale batteries from 5 kWh to 100 kWh under the Cheaper Home Batteries Program. The discount decreases over time until 2030.
For a farm, a battery can shift solar from the middle of the day to the evening milking or overnight pumping. It can also keep essential equipment running in an outage if the system is designed for backup, which matters on a dairy where milk cooling cannot wait for the grid. The battery backup page explains how backup design works.
What will a careful farm or commercial installer check?
A larger system on a working property has more to get wrong than a house roof. A careful provider will:
- Ask for 12 months of bills or interval data and match system size to the real daytime load.
- Inspect the shed or building roof structure, sheeting condition and fixing points before quoting.
- Check the main switchboard, supply capacity and whether all three phases are available.
- Plan cable routes from distant sheds to the main switchboard, allowing for voltage drop.
- Keep panels and inverters away from areas washed down with water or exposed to animal damage.
- Apply to AusNet before any work starts and tell you the approved export limit in writing.
- Arrange the independent inspection and Certificate of Electrical Safety that Energy Safe requires.
They should also refuse to install on a roof with rusted or brittle sheeting until it is repaired, and refuse to promise payback figures without your actual consumption data.
How is farm and business solar installed?
- Site visit to look at roofs, ground space, the switchboard and supply.
- Load review using bills or interval data, and a written system design.
- Written quote listing panels, inverters, any battery, mounting and switchboard work.
- Network application to AusNet and, where needed, manual assessment.
- Installation, with the accredited installer on site at each required stage.
- Independent electrical inspection and Certificate of Electrical Safety.
- Meter reconfiguration and commissioning, then a handover of monitoring and shutdown procedures.
Ground-mounted arrays are an option where shed roofs are too small, shaded or in poor condition, but they add frame and trenching work.
What does farm or business solar cost?
There is no published price band on this site for commercial or farm systems, because the cost depends so heavily on size, roof type, cable runs and switchboard upgrades. For a small business on a residential-sized system, the residential bands on the solar and battery cost guide give a rough starting point. For anything larger, get at least two written quotes based on the same load data so you can compare them line by line.
Where around Warragul does this apply?
The same rules apply on a farm near Darnum, Buln Buln or Neerim South as they do to a shop in the Warragul or Drouin town centre: the network limits, accreditation and inspection steps are statewide or set by the distributor, not by the town. The Nilma area page covers the rural-residential land just east of Warragul. Whatever your location, an independent local installer assesses the site and gives you a quote; this website passes on the enquiry.
Next step: describe your property and loads
Before you enquire, gather a year of power bills or your interval data, a list of the main equipment and when it runs (milking times, pumps, cool rooms, compressors), whether you have single or three phase supply, roof type and size of the sheds or buildings, and the distance from each shed to the main switchboard. Note whether you want a battery for evening loads or outage backup. Then send a farm or business solar enquiry with your address and those details.
Frequently asked questions
- Can I put solar on a dairy shed roof near Warragul?
Often yes, if the roof structure and sheeting are sound and the shed is close enough to the main switchboard. An installer should inspect the roof, the supply and the cable route before quoting, and may suggest a ground-mounted array if the shed roof is unsuitable.
- Do I need three phase power for a farm solar system?
Not always, but AusNet's standard process allows up to 10 kW of inverter capacity per phase. Three phase supply lets a site go up to 30 kW across the phases under that process. Larger or single phase systems above 10 kW need a paid manual assessment.
- Is the federal battery discount only for homes?
No. The federal department responsible says households, businesses and community organisations can get the discount on eligible batteries from 5 kWh to 100 kWh. The discount reduces each year until 2030, so check the current rate with the installer.
- Can I claim business solar as a tax deduction?
Tax treatment depends on your business structure and how the system is used. Ask your accountant before you sign a quote. An installer can give you an itemised invoice to help, but cannot give tax advice.
- How do I compare quotes for a large farm system?
Give every installer the same bills or interval data and ask each for a written design showing panel and inverter models, system size, export limit assumptions, switchboard work and the network application. That lets you compare like with like rather than headline prices.
