Who connects your solar in Doncaster: United Energy

Doncaster is on the United Energy network across east and south-east Melbourne. All five Victorian distributors share the same export rules.

United Energy applies the Victoria-wide 5 kW per phase export limit. A single-phase home can install up to a 10 kW inverter (5 kW export); a three-phase home (common on larger Doncaster homes) can export up to 15 kW.
You can fit more panels than inverter capacity to lift output.
United Energy is part of the Victorian flexible (dynamic) export rollout over 2026–2031.
Large hilltop homes here often have three-phase power and big roofs, suiting a larger system.

How much solar generates in Doncaster

Doncaster is in STC Zone 4 (rating 1.185), so it earns fewer federal STCs than NSW. A well-installed, north-facing 6.6 kW system generates around 8,500–9,000 kWh a year, and the area's large, elevated, open roofs make a bigger system easy to fit with little shading.

The hilltop aspect means most homes get clear sun across the day.

What a 6.6 kW system actually saves here

Self-consumption is decisive in Victoria: the minimum feed-in tariff is just 0.04c/kWh flat for 2025–26, while you pay roughly 28–32c/kWh to buy power back. Larger Doncaster homes with ducted air-conditioning and a pool have ample daytime load to use a good system.

Run the pool pump, dishwasher and a hot-water heat pump in the middle of the day, or add a battery for the evening peak.

Getting it right in Doncaster

Apply for the Solar Victoria rebate before installing — approval must come first, via an authorised retailer.
Check whether your home is three-phase (common on larger homes) — it allows a bigger system and up to 15 kW export.
Big elevated roofs suit a full or oversized array; ask for a battery-ready inverter even if storage comes later.
With near-zero feed-in, design for self-consumption and consider a battery for the evening.

Rebates for Doncaster homes

Unlike NSW, Victoria has a state solar rebate. The Solar Homes program offers eligible owner-occupiers up to $1,400 off a solar PV system (plus an optional interest-free loan of up to $1,400), on top of the federal STC discount. An income test applies (under $210,000, reducing to $150,000 from 1 July 2026), the property must be worth under $3 million, with no previous solar rebate at the address.

Victoria is STC Zone 4, so the federal discount is a little smaller than in NSW, and the feed-in tariff is even lower. For batteries, the federal Cheaper Home Batteries Program (~30% off) applies — a natural fit for Doncaster's large homes and three-phase supplies.

Doncaster solar panels questions

Is solar worth it in Doncaster?

Yes — the housing is well suited. Large, elevated, mostly unshaded roofs (often with three-phase power) make a generous system easy, and a 6.6 kW array generates around 8,500–9,000 kWh a year. Eligible owner-occupiers take up to $1,400 off via Solar Victoria on top of the federal discount. With ducted cooling and pools common, there's plenty of daytime load to self-consume — which is where the value is, since Victoria's feed-in tariff is near zero — and larger homes often pair well with a battery.

How much do solar panels cost in Victoria?

A quality 6.6kW system typically costs $4,000–$6,500 after the federal STC discount, with larger 10–13kW systems running higher. The Solar Homes Program rebate can reduce the price further for eligible households.

Is solar worth it in Victoria?

For most homes, yes. A 6.6kW system commonly saves $1,000–$1,600 a year and pays for itself in three to five years, then keeps saving for the 25-year life of the panels.

What size solar system do I need?

It depends on your usage and roof. 6.6kW suits many homes; go larger (10kW or more) if you're all-electric, plan to add a battery or EV, or use a lot of power during the day.
