Solar Panels Melbourne: Solar & Battery Installation Guide

Solar panels in Melbourne pay off well in 2026, even though the city gets less sun than Adelaide or Brisbane. A typical 6.6kW system costs roughly $4,500–$8,000 after the federal discount, eligible households can take another $1,400 off with the Solar Homes rebate, and Victoria’s move away from gas means more homes can use their own solar for hot water, heating and cooking. This guide covers what solar produces in Melbourne, what it costs, the Victorian rebates and rules, your local distributor, batteries, commercial systems and how to choose an installer.

It’s written for Melbourne homeowners and business owners who want straight local facts. Where a number changes often, we give a range and a date so you can check it against the official source.

Are solar panels in Melbourne worth it in 2026?

For most owner-occupied homes, yes. Melbourne’s lower sunshine is often overstated. Summer output is strong, and the main weakness is winter, when short days and cloud cut generation sharply. You size the system with that in mind.

The bigger change is how solar earns its money. Since 1 July 2025 there has been no minimum feed-in tariff in Victoria, so exports earn only a few cents (sometimes nothing). The savings now come from:

• Using your own solar for air conditioning, hot water, the dishwasher, washing and EV charging during the day.
• Going electric. Replacing gas hot water and heating with efficient electric appliances that run on solar, which also lets many homes drop the gas supply charge.
• Choosing the right plan. The Victorian Default Offer now includes a cheaper “solar soak” period from 11am to 4pm, and the Midday Power Saver gives three free hours.
• Adding a battery to shift midday solar into the evening peak.

Our guide to solar savings, feed-in tariffs and power bills shows how to work out your own payback.

How much power do solar panels produce in Melbourne?

The Clean Energy Council’s guideline figure for Melbourne is about 3.6 kWh per kW of panels per day, averaged over a year. Well-designed systems often reach 3.6–3.8 kWh/kW/day. December and January days can produce around double the annual average, while June and July days can produce well under half of it.

Based on 3.6 kWh/kW/day. Real output depends on roof direction, tilt, shading and inverter size.

Because winter output is so much lower, many Melbourne households who are replacing gas heating or hot water choose a slightly larger system than they would in Adelaide. North-facing roofs give the most energy across the year, and east–west layouts spread generation across the day. Winter shade matters more in Melbourne because the sun sits low in the northern sky, so check for trees and neighbouring buildings to the north. See how much power a 6.6kW solar system produces in Adelaide and Melbourne for month-by-month detail.

How much do solar panels cost in Melbourne in 2026?

Typical 2026 market prices for good-quality residential systems, after the federal STC discount and including GST (before any Solar Homes rebate), look like this:

Price differences come from panel and inverter brand, roof type and pitch, double-storey access, switchboard upgrades and whether you need microinverters for a shaded roof. These are indicative market prices, not quotes. Our full breakdown is in how much solar panels cost in Melbourne in 2026, and how to compare solar quotes shows what to check before you sign.

How the STC discount works in Melbourne (Zone 4)

The federal “solar rebate” comes from small-scale technology certificates (STCs). Your system creates them, and the installer usually takes their value off your quote:

System size (kW) × zone rating × deeming years = number of STCs

Melbourne is in Zone 4, with a rating of 1.185 MWh per kW. Systems installed in 2026 get 5 deeming years. For a 6.6kW system:

• 6.6 × 1.185 × 5 = 39.1, rounded down to 39 STCs.
• At about $39.85 per STC (early October 2026), that’s roughly $1,550 off.
• Add the Solar Homes rebate of up to $1,400 and an eligible household gets about $2,950 off a 6.6kW system.
• Install in 2027 and the deeming period drops to 4 years: 31 STCs, or about $1,235, roughly $320 less.

STC prices move and some installers apply a slightly lower rate, so treat these as estimates. STCs explained covers the calculation in more detail.

What size solar system suits a Melbourne home?

Check your bills for average daily usage in kWh, and think about what’s coming: a heat pump, an induction cooktop, an EV or a battery. As a rough guide:

• 6.6kW solar system: suits smaller households using up to about 15–20 kWh a day, especially on single-phase power.
• 10kW solar system: suits families, homes replacing gas appliances and anyone planning a battery.
• 13kW solar system: suits all-electric homes, EV owners and large households with three-phase power.

Our guide what size solar system do I need compares the three in detail, and all our home packages are on the residential solar page.

Who is your electricity distributor in Melbourne?

Your retailer sends the bill, but a distributor owns the poles and wires to your home. Melbourne is split between five distributors, and the one you’re on approves your solar connection, sets your export limit and handles the emergency backstop.

Boundaries don’t follow suburb names neatly, so don’t guess. To find yours:

1. Check your electricity bill. The distributor is usually named, often near your NMI (National Meter Identifier) or the faults and emergencies number.
2. Use the Victorian Government’s “Find your energy distributor” page, which includes a distributor map.
3. Ask your installer. A good installer confirms your distributor and export limit as part of the quote.

Export limits and the emergency backstop

Many Melbourne homes can export up to about 5 kW per phase, but limits can be lower on busy parts of the network, and some distributors now offer flexible export arrangements. Since 1 October 2024, new and upgraded systems up to 200 kW must also support Victoria’s emergency backstop. This needs a compatible inverter with a reliable internet connection, so the distributor can reduce solar output in a rare grid emergency when AEMO directs it. Your home stays powered.

Victorian solar rebates and rules in 2026

Victoria still has a state solar rebate, which South Australia does not. Here’s what applies in Melbourne as of October 2026:

Solar Homes: who qualifies?

To get the Solar Victoria solar panel rebate you must be an owner-occupier with a combined household taxable income under $150,000 (down from $210,000 on 1 July 2026), the property must be worth under $3 million, and the address can’t have had solar installed in the last 10 years or a previous Solar Homes solar or battery rebate. From 1 May 2026 you choose the interest-free loan when you apply. You must use a Solar Victoria authorised retailer, and the rebate comes off your invoice. Full details are in Victoria solar rebates 2026. Landlords have a separate stream, covered in solar for rental properties in Victoria, and our complete guide to solar and battery rebates in SA and Victoria brings it all together.

Feed-in tariffs and the Midday Power Saver

With no minimum feed-in tariff, retailer rates vary widely and can be zero, so check your plan’s actual rate. The Midday Power Saver, available from 1 October 2026, gives households with a smart meter free grid power from 11am to 2pm (up to 24 kWh a day). Rates outside that window are often higher, so it suits homes that can shift big loads to the middle of the day. Compare the options in Victoria’s feed-in tariff in 2026 and Solar Sharer vs Midday Power Saver.

Solar and Victoria’s move away from gas

Victoria is phasing out gas in homes, and that makes solar more valuable. From 1 January 2027, all new homes must be built all-electric. From 1 March 2027, when a gas hot water system in an existing home reaches the end of its life, it must be replaced with an electric one (repairs are still allowed). Minimum energy standards for rental homes also start phasing in from 1 March 2027.

A heat pump hot water system running in the middle of the day on solar is one of the cheapest ways to heat water. Solar Victoria’s hot water rebate is up to $1,000 ($1,400 for locally made products), and combined with VEU discounts it can reach $2,030 for locally made units. Once your hot water, heating and cooking are electric, you can disconnect gas and stop paying the daily supply charge.

Read more: Victoria’s 2027 gas hot water rules, Victorian Energy Upgrades 2026, how to disconnect from gas in Victoria and our home electrification guide.

Solar batteries in Melbourne

Victoria no longer offers a state battery rebate or battery loan for owner-occupiers, so the federal Cheaper Home Batteries Program is the main incentive. It is most generous until 31 December 2026.

Worked example: 13.5 kWh battery

• Installed by 31 December 2026: 13.5 × 6.8 = about 91 STCs, worth roughly $3,400–$3,600 at $37–$40 per STC.
• Installed from 1 January 2027: 13.5 × 5.7 = about 76 STCs, roughly $2,800–$3,000.

Battery STCs are the same in every climate zone, so Melbourne households get the same discount per kWh as Adelaide. Before the discount, typical 2026 prices run at roughly $700–$1,300 per usable kWh. The discount tapers on bigger batteries (100% for the first 14 kWh, 60% from 14–28 kWh, 15% from 28–50 kWh).

In Melbourne, battery sizing needs extra care. A battery that fills easily in summer may only half-charge on a cloudy July day, so a larger solar array often matters as much as battery size. To qualify, the battery must be on the approved list, be VPP-capable and be installed by an SAA-accredited installer.

Commercial solar for Melbourne businesses

Businesses that operate during the day can use most of their solar on site, which makes commercial systems some of the best-returning solar investments in Victoria. Typical 2026 market prices are roughly $0.70–$1.20 per watt after STCs, with larger systems at the lower end. Common sizes:

• 20kW commercial solar system: cafés, small offices, clinics.
• 30kW commercial solar system: workshops, retail, light industrial.
• 50kW commercial solar system: warehouses, cold storage, larger sites.
• 99kW commercial solar system: factories, schools and big daytime users.

Victorian businesses have some extra advantages in 2026:

• Stack STCs with VEU certificates. Commercial systems from 30 kW to 200 kW can earn Victorian Energy Efficiency Certificates (VEECs) on top of STCs.
• STCs now reach 1 MW. From 1 October 2026, systems between 100 kW and 1 MW can claim STCs with a fixed 5-year deeming period.
• Tax. The $20,000 instant asset write-off is now permanent for small businesses with turnover under $10 million; most systems cost more and go into the small business pool. Ask your accountant.

Systems up to 200 kW also need emergency backstop capability. Read more: commercial solar in Melbourne, commercial solar costs in 2026 and our commercial solar guide for Australian businesses. Our business packages are on the commercial solar page.

Solar maintenance and repairs in Melbourne

Melbourne’s regular rain keeps most panels reasonably clean, but leaves, moss and lichen can build up under trees, and pigeons often nest under panels in the suburbs. Inverters are usually the first part to fail, often after 10–15 years.

• Check your monitoring app monthly and compare with the same month last year, since winter output is naturally low.
• Hose off visible dirt from the ground; don’t climb onto the roof.
• Book a professional inspection every few years or whenever the inverter shows an error.

Our solar panel maintenance, repairs and performance guide covers cleaning, common faults and when to upgrade an older system.

Choosing a solar installer in Melbourne

A good installation matters more than the brand on the panels. Before you sign, check that:

1. The installer is accredited by Solar Accreditation Australia (SAA), which is required for STCs and the battery discount.
2. If you’re claiming Solar Homes, the retailer is authorised by Solar Victoria.
3. All panels, inverters and batteries are on the Clean Energy Council approved products lists.
4. The quote names exact models and covers distributor pre-approval, emergency backstop setup and any switchboard work.
5. Battery installs meet AS/NZS 5139:2019 and inverters meet AS/NZS 4777.2:2020.
6. Product, performance and workmanship warranties are in writing, with a local service contact.

Frequently asked questions

How much do solar panels cost in Melbourne in 2026?

Typical 2026 market prices are about $4,500–$8,000 for a 6.6kW system and $8,000–$12,000 for a 10kW system, after the federal STC discount and including GST. Eligible households can take up to $1,400 more off with the Solar Homes rebate. Roof type, brands, switchboard work and batteries all change the final price.

Can I still get the Solar Victoria rebate in 2026?

Yes. The Solar Homes rebate is still up to $1,400, with an optional interest-free loan of up to $1,400. Since 1 July 2026 the combined household income cap is $150,000, the home must be worth under $3 million, and the address can’t have had solar in the last 10 years. You must use an authorised retailer.

Is solar worth it in Melbourne with less sun?

Usually, yes. A well-oriented Melbourne system averages about 3.6 kWh per kW per day, so a 6.6kW system makes roughly 8,700 kWh a year. With low feed-in tariffs, the savings come from using solar yourself, especially for heat pump hot water, heating and EV charging. Size the system with winter output in mind.

Who is my electricity distributor in Melbourne?

Melbourne is served by CitiPower, Jemena, AusNet Services, United Energy and Powercor. Boundaries don’t follow suburbs neatly, so check the distributor named on your electricity bill or use the Victorian Government’s Find your energy distributor map. Your distributor approves your solar connection and sets your export limit.

Is there a battery rebate in Victoria?

There is no state battery rebate for owner-occupiers in Victoria in 2026. The federal Cheaper Home Batteries Program gives 6.8 STCs per usable kWh for installs until 31 December 2026, worth roughly $3,400–$3,600 on a 13.5 kWh battery. From 1 January 2027 the rate drops to 5.7 STCs per kWh.

Do I have to replace my gas hot water in 2027?

Only when it reaches the end of its life. From 1 March 2027, a gas hot water system in an existing Victorian home that needs replacing must be replaced with an electric one, such as a heat pump. Repairs are still allowed. Rebates and VEU discounts can cover a large part of the cost.
