Frankston is on the United Energy network, which covers east and south-east Melbourne down to the Mornington Peninsula. 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 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.
- Near the bay, plan for coastal hardware alongside the export limit.
How much solar generates in Frankston
Frankston is in STC Zone 4 (rating 1.185), so it earns fewer federal STCs than NSW. The mild bayside climate gives a well-installed, north-facing 6.6 kW system around 8,600–9,100 kWh a year.
Roofs are generally workable; coastal exposure near the foreshore is the main physical factor to plan for.
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 | ~8,800 kWh/yr |
|---|---|
| Used at home (~33%) | 2,904 kWh × 30c = ~$871 saved |
| Exported (~67%) | 5,896 kWh × 4c = ~$236 earned |
| Indicative annual benefit | ~$1,107 |
Getting it right in Frankston
- Apply for the Solar Victoria rebate before installing — and use the optional interest-free loan if upfront cash is tight.
- Near the foreshore, specify marine-grade racking and check warranties cover coastal zones.
- Get several quotes — a good price plus the rebate is what makes the payback work.
- With near-zero feed-in, design for self-consumption and consider a battery.
Rebates for Frankston homes
Unlike NSW, Victoria has a state solar rebate, and in a value-focused market like Frankston it makes a real difference. 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.

Full Victorian solar panels rebate guide →Frankston solar panels questions
Is solar worth it in Frankston?
Yes for most homes. A 6.6 kW system by the bay makes around 8,600–9,100 kWh a year, and eligible owner-occupiers take up to $1,400 off via Solar Victoria on top of the federal discount, with an optional interest-free loan — helpful in a value-focused market. Victoria's feed-in tariff is near zero, so the savings come from using your own power during the day. Near the foreshore, use marine-grade hardware, and get a few quotes to land a good price.
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.
