Solar Panels in Lilydale, VIC — Costs, Rebates & Quotes
Lilydale is the gateway to the Yarra Valley, where Melbourne's suburbs give way to hills, vineyards and semi-rural blocks. The undulating, treed terrain is the defining solar factor: ridgelines and tall trees can shade parts of a roof through the day, so orientation and shading assessment matter more here than on the flat.
This page covers solar for Lilydale: the AusNet network rules, the hill-country shading factor, what a system generates, the Victorian rebates, and the savings maths — checked against the issuing authorities and dated below.

Lilydale is on the AusNet Services network, which covers the outer east, the Yarra Valley 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 — useful for offsetting hill-country shading.
- AusNet runs a large rural network into the Yarra Valley; on long feeders some sites need site-specific connection checks.
- Storms and outages are more common in the hills, so a battery with backup is genuinely useful.
How much solar generates in Lilydale
Lilydale 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 8,300–8,800 kWh a year, but on hilly or treed blocks the real figure depends heavily on shading.
Get the orientation and shading modelled across the day and seasons — on a shaded or steep block, microinverters or optimisers help 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 and outage cover.
| Solar generated | ~8,500 kWh/yr |
|---|---|
| Used at home (~33%) | 2,805 kWh × 30c = ~$842 saved |
| Exported (~67%) | 5,695 kWh × 4c = ~$228 earned |
| Indicative annual benefit | ~$1,070 |
Getting it right in Lilydale
- Apply for the Solar Victoria rebate before installing — approval must come first, via an authorised retailer.
- Get the shading and orientation modelled carefully — hills and tall trees can clip output; optimisers help.
- On rural and acreage blocks, confirm the AusNet feeder can take your export before sizing a bigger system.
- Consider a battery with backup — storms and outages are more common in the Valley.
Rebates for Lilydale 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 — backup is worthwhile in the storm-prone hills.

Does Lilydale's hilly, treed terrain affect solar?
Yes — more than on the flat. Ridgelines and tall trees can shade parts of a roof through the day, so a clear north-facing roof might make 8,300–8,800 kWh a year from a 6.6 kW system while a shaded or steep one makes less. A proper shading assessment, the right orientation, and sometimes optimisers make the difference. Eligible owner-occupiers still take up to $1,400 off via Solar Victoria on top of the federal discount, and a battery with backup is worth costing given the Valley's storms.
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.
