Farm and business solar around Traralgon

Commercial solar in Traralgon covers anything from a workshop roof to a dairy shed or a small office block. It differs from a house system in three ways: the site often has three phase supply, the system can be much larger, and different incentives apply, mainly the Victorian Energy Upgrades discount for systems of 30 to 200 kW and the federal certificate scheme. A business system pays back best when most of its output is used on site during working hours.

Which farms and businesses suit solar?

Solar suits sites that use most of their power in daylight. Around the Valley that includes:

• dairies, where milking, vat cooling and hot water run every morning and afternoon
• irrigation and stock water pumps on farms
• workshops, mechanics and fabrication sheds running compressors, welders and machine tools
• cool rooms and refrigeration in food businesses and farm stores
• offices, clinics and retail with air conditioning through the working day
• community buildings, schools and sports clubs with large flat or low pitch roofs

A site that mostly uses power at night, or only a few days a week, sends more of its output to the grid and earns less from it. That does not rule solar out, but it changes the size worth installing.

How do you match solar output to a business’s daytime load?

This is the core of a good commercial quote. Ask the provider to work through these questions with you:

1. When does the site use most of its power? Milking times, shift hours and pump schedules all matter.
2. Which loads can move into the middle of the day? A pump on a timer or a hot water unit can often shift.
3. How much is used on weekends and in the off season?
4. Is the load the same all year, or does it peak with harvest, calving or summer cooling?
5. What does the retailer charge for demand, and would solar reduce the peak?

Interval data from your retailer or meter, usually a download of half hourly readings, gives the provider a far better picture than a single quarterly bill. If you cannot get it, send twelve months of bills.

What incentives apply to business solar in Victoria?

Program	What it covers	Who delivers it	Source
Victorian Energy Upgrades commercial and industrial solar discount	Systems between 30 and 200 kW at Victorian businesses and non-residential sites	VEU accredited providers	Solar Victoria
Victorian Energy Upgrades project-based activity	Systems over 200 kW	Through the VEU program	Same Solar Victoria page
Small-scale Renewable Energy Scheme	Certificates for eligible solar, now including systems up to 1 MW installed from 1 October 2026	SAA accredited installers, approved products	Clean Energy Regulator

Solar Victoria says all Victorian businesses and non-residential sites can apply for the commercial and industrial discount, including community buildings, schools and hospitals. The system, its products, the product warranties and the system size all have to meet the program’s rules, which are set out on the Victorian Energy Upgrades website.

The federal change is recent. The Clean Energy Regulator says the scheme now covers mid-scale solar from 100 kW to 1 MW installed from 1 October 2026, and that applications for those systems will not open until mid to late November 2026, once its systems are ready. A business installing a large system now should ask the provider how and when the certificates will be claimed. For mid-scale systems in that range, the Regulator does not require an accredited designer, but the installer must still be accredited by Solar Accreditation Australia and the panels and inverters must be on the Clean Energy Council approved list.

How does a business solar project usually run?

1. Site visit to measure the roof or ground area, inspect the structure and look at the switchboard and meter.
2. Review of the load data and a design sized to the daytime use.
3. A written proposal that names the incentive the provider will apply and who claims it.
4. The network application to AusNet, with installation waiting on approval.
5. Installation by SAA accredited installers holding a Victorian electrical licence.
6. Testing, an independent inspection and a Certificate of Electrical Safety, since solar is prescribed electrical work in Victoria.
7. Meter changes, monitoring set up and a handover of the shutdown procedure for staff.

Ask how long each stage usually takes for a site like yours, and where the project could stall. For a business, the network step and the incentive paperwork are often slower than the installation itself.

Does a farm or business need three phase power for solar?

Not always, but it helps. Many farms, workshops and commercial buildings already have three phase supply for motors and pumps. AusNet Services runs a standard process for three phase connections with up to 30 kW of combined inverter capacity and 15 kW of export across the three phases. Systems larger than that go through a separate connection process with AusNet. The AusNet export limits guide covers the smaller-system rules for readers who want the detail.

A single phase rural property can still take solar, but the export limit is lower, so self consumption matters even more.

What does a careful commercial provider check?

Larger systems involve more risk, so the checks go further than on a house:

• the roof structure and sheeting, since shed roofs vary widely in age and strength
• roof access and safe working methods on high or fragile roofs
• the main switchboard and its spare capacity, plus the distance from the array to it
• earthing and lightning risk on exposed farm buildings
• dust, hay, chemicals and stock near the inverter location
• the existing network connection and what AusNet will approve
• whether the business has the paperwork the incentive requires

A provider should also tell you what it will not do, such as fitting panels to a roof that is not sound or mounting an inverter in a dusty feed shed without a suitable enclosure.

What does commercial solar cost?

There is no reliable published price band for commercial and farm systems that this site can quote, because roof type, distance to the switchboard, the connection process and the incentives differ so much from one site to the next. The pricing needs a site assessment. For household systems, the Traralgon cost guide sets out the published bands. To get a figure for a shed, dairy or business roof, request a business solar assessment with your bills attached.

What should Valley farm sites plan for?

Farm and lifestyle properties in districts such as Yinnar and Glengarry can mean big shed roofs and long cable runs back to the meter, which the provider prices in. Ask early whether your site already has three phase supply, since that shapes the design. The businesses that respond to enquiries from this site are independent; each one assesses the site, prices the system and does the installation under its own licences and accreditation.

Next step: send the details of your site

A business solar enquiry is easiest to price when it says what the business is (dairy, workshop, office, farm store), whether the site has single or three phase supply, and the approximate roof or ground area available. Attach interval data or twelve months of bills, and mention the hours the site runs. Then send a farm or business solar enquiry and a provider can arrange the site visit.
