Cranbourne 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. Single-phase homes can install up to a 10 kW inverter (5 kW export); three-phase homes (common in new Cranbourne estates) can export up to 15 kW.
- You can fit more panels than inverter capacity — easy on big new-estate roofs.
- United Energy is part of the Victorian flexible (dynamic) export rollout over 2026–2031.
- Large new roofs and three-phase supplies make a bigger system or battery-ready setup straightforward.
How much solar generates in Cranbourne
Cranbourne 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 8,600–9,100 kWh a year, and the large new roofs make a bigger system easy.
New homes usually have clean, simple, unshaded roofs.
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. With many Cranbourne households commuting, timers or a battery matter for using your own solar.
Run appliances and a hot-water heat pump on daytime timers, or add a battery for the evening peak.
| Solar generated | ~8,800 kWh/yr |
|---|---|
| Used at home (~32%) | 2,816 kWh × 30c = ~$845 saved |
| Exported (~68%) | 5,984 kWh × 4c = ~$239 earned |
| Indicative annual benefit | ~$1,084 |
Getting it right in Cranbourne
- Apply for the Solar Victoria rebate before installing — approval must come first, via an authorised retailer.
- Most new homes are three-phase — confirm yours for a larger system and up to 15 kW export.
- If the house is empty on weekdays, a battery (federal ~30% off) or timed loads make a big difference.
- Big roofs suit oversized arrays; ask for a battery-ready inverter.
Rebates for Cranbourne 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 good fit for big new roofs and weekday-empty homes.

Full Victorian solar panels rebate guide →Cranbourne solar panels questions
Is solar worth it in Cranbourne?
Yes — the new housing suits it. Large estate roofs (often three-phase) make a generous system easy, and a 6.6 kW array generates around 8,600–9,100 kWh a year. Eligible owner-occupiers take up to $1,400 off via Solar Victoria on top of the federal discount. Because many households commute and Victoria's feed-in tariff is near zero, use timers or a battery to lift self-consumption — that's where the savings are, not in exporting.
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.
