Solar Panels in Croydon, VIC — Costs, Rebates & Quotes
Croydon is a settled, leafy outer-eastern suburb of mostly freestanding family homes on good-sized blocks. It's straightforward solar territory — workable roofs, plenty of them — with the main local watch-point being shade from the area's many mature trees.

Croydon is on the AusNet Services network across the outer east and eastern Victoria. All five Victorian distributors share the same export rules.
- AusNet 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 can export up to 15 kW.
- You can fit more panels than inverter capacity to lift output.
- Victoria is moving to flexible (dynamic) export connections over the coming years.
- Freestanding homes here generally have good, workable roof space.
How much solar generates in Croydon
Croydon 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.
Mature trees on many Croydon blocks are the main thing to design around — a shade assessment, and optimisers where needed, protect output.
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. Use your own solar during the day rather than exporting it for a few cents.
Run the dishwasher, washing machine and a hot-water heat pump in the middle of the day, or add a battery for the evening peak.
| Solar generated | ~8,700 kWh/yr |
|---|---|
| Used at home (~33%) | 2,871 kWh × 30c = ~$861 saved |
| Exported (~67%) | 5,829 kWh × 4c = ~$233 earned |
| Indicative annual benefit | ~$1,094 |
Getting it right in Croydon
- Apply for the Solar Victoria rebate before installing — approval must come first, via an authorised retailer.
- Get a shade assessment — mature trees are common; optimisers or microinverters help on affected roofs.
- On an older home, allow for a possible switchboard upgrade.
- With near-zero feed-in, design for self-consumption and consider a battery.
Rebates for Croydon 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.

Is solar worth it in Croydon?
Yes for most homes. Croydon's freestanding houses have good roof space, and a 6.6 kW system makes 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. The main thing to check is shading from the suburb's many mature trees — a good installer models it and may use optimisers. Victoria's feed-in tariff is near zero, so the value is in using your own power during the day.
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.
