Fact Checked Fact Checked

In this article, Canstar Blue will walk you through everything that Victorians need to know about solar. We look at installation prices, rebates, feed-in tariffs, buying tips and more.

The energy industry in Australia is rapidly evolving. While we’ve traditionally relied on large fossil fuel generators to meet our electricity needs, solar, storage and other renewable energy technologies are now helping households take power back into their own hands.

Hundreds of thousands of Victorians are already reaping the benefits of solar, and trimming their power bills. With solar panel prices still coming down and a host of government solar and battery rebates to help get you started, it’s worth considering if now’s the right time to buy or upgrade. If you’re on the fence about solar in Victoria, keep reading to find out the expected price, feed-in tariffs available and some hot buying tips.

How much do solar panels cost in Victoria?

Victorians should expect to pay between $4,100 and $8,430 for a standard solar system, depending on the size of the system. A small system (3kW and under) should usually cost no more than $4,000, while systems that are 10kW or larger can cost in excess of $9,000.

The following table shows typical solar installation costs in Victoria compared to the national average. Keep in mind that these prices do not account for certain state solar rebates (discussed below). This means solar may cost far less than you might expect.

3kW 4kW 5kW 6kW 7kW 10kW
Victoria $3,720 $4,150 $4,630 $5,200 $6,070 $7,850
National Average $4,060 $4,710 $5,240 $5,960 $6,880 $9,250

How many households have solar in Victoria?

There are approximately 510,000 Victorian households with solar, generating almost a third of the state’s total electricity demand, according to the Solar Victoria.

On 1 July 2019, the Victorian Government announced the ‘Solar Homes Program’, which aims to further encourage the uptake of solar with an upfront rebate. The government intends to help households invest in solar, while decreasing the state’s carbon emissions. So, if you don’t already have solar, now may be the perfect time to get on board.

Victoria solar rebates and incentives

Victorians currently benefit from some of Australia’s most generous solar incentive schemes. These include Small-scale Technology Certificates (STCs), Feed-in tariffs (FiTs), and the already mentioned Solar Homes Program.

Small-scale technology certificates in Victoria

Small-scale Technology Certificates (STCs) operate as a form of rebate on the initial purchase price of a solar system. When a customer installs a renewable energy generator, be it wind, hydro or solar, they will receive a number of certificates.

STCs can be exchanged for about $40, and can save you hundreds or even thousands on your solar system. The number of STCs that you receive depends on the expected electricity output of your solar system over the course of its life.

Households generally receive more STCs if they live in a sunny area or install a larger system. Those in Zone 1 (see diagram) receive the most certificates for installing solar, while customers in Zone 4 receive less. As you can see, the majority of Victoria – including Melbourne – is situated in Zone 4.

Victoria Solar Homes Program

According to Solar Victoria, eligible households may receive a rebate up to $1,400 off the cost of a solar panel (PV) system. Eligible households with solar battery systems may be able to apply for an interest-free loan, while households that install a solar hot water system may be eligible for a rebate of up to $1,000.

To be eligible, households must have a total annual income under $210,000, and be the owner-occupier of the property installing solar. The home must be valued at under $3 million and the property must not already have a solar system installed, meaning the rebate won’t apply if you’re just looking to upgrade an existing system.

VIC solar feed-in tariffs

When your solar panels produce electricity and no one is home to use it, the excess power flows on to the shared electricity network – commonly known as ‘the grid’. In exchange for the electricity, solar customers receive a small rebate known as a ‘feed-in tariff’ (FiT) for each kWh of power exported.

There are two types of feed-in tariffs available in Victoria – a ‘single rate’ tariff and a ‘time-varying’ tariff. As the names suggest, the single rate feed-in tariff applies one rate for all electricity produced, while the time-varying FiT applies different rates at different times of the day. The minimum single rate feed-in tariff under Victorian law is currently set to 3.3c/kWh.

There are now two options available for customers on a time-varying tariff. Option 1 includes a rate of 2.8c/kWh during the day (7am to 3pm and 9pm to 10pm weekdays, and 7am to 10pm on weekends). The overnight rate is 7.8c/kWh and applies from 10pm to 7am. There is also an early evening rate on weeknights, which is set at 7.0c/kWh and applies from 3pm to 9pm.

For Option 2 time-varying FiTs, customers earn the highest FiT at peak times from 4pm to 9pm weekdays, while lower off-peak rates apply every day from 10am to 2pm. All other times are considered the ‘shoulder period’ and a moderate rate is applied. The minimum time-varying rates are 2.1c/kWh for off-peak, 4.1c/kWh for shoulder, and 8.4c/kWh for peak.

VIC solar companies offering feed-in tariffs

The Victorian electricity market is incredibly competitive, and while the state has minimum feed-in tariffs, many retailers will offer more than that to win your custom. It’s important to shop around for a competitive feed-in tariff, but also don’t forget to consider other important things like electricity usage rates, discounts and contract terms. A good FiT for your solar power might not necessarily mean a good deal if you’re paying too much for electricity.

Solar batteries in Victoria

Batteries allow homes to store excess power generated by their solar panels, rather than feeding into the grid. The electricity stored in the battery can be used later on – even at night or through a blackout.

Since a typical feed-in tariff is much lower (6.7-8c/kWh) than the rate you would pay for electricity usage (typically 20c/kWh or more), households can save even more by storing their solar to use for themselves later on, rather than sending it to the grid.

Unfortunately, solar batteries don’t come cheap. While you can find smaller modular units for around $2,000, larger batteries can set you back between $8,000 and $12,000. In some cases, the savings generated from a battery could justify the cost in the long run. Typically it will take between 10 to 15 years for a battery to pay for itself, though keep in mind that some batteries aren’t warranted to last that long.

A solar battery is most likely to return dividends for homes that use a lot of electricity, or are charged high electricity usage rates. It will also be useful if you live rurally and grid connections are expensive, or your network has imposed export limits. Whether or not a solar battery is a sound investment is entirely dependent on your circumstances.

Is it worth getting solar in Victoria?

While solar is undoubtedly expensive, the savings you make on electricity can often cover the cost of the system after several years. The current rebates and incentives – particularly the Victorian Solar Homes Program – help to make solar a lot more affordable, meaning now is probably as good of time as any to on board with solar.

With that said, solar won’t be the right choice for some – especially those households that receive little sunlight through the year and/or are already receiving a reasonable deal on their electricity. As prices for solar panels and batteries continue to fall however, solar may still be a wise investment down the road.

FAQs about solar in VIC

If you’re after rooftop solar, then you need to make sure your roof is up to the task. Here are some handy questions to ask yourself before going ahead:

  • How sunny is your roof? Solar works best when the roof is unshaded and your suburb receives plenty of sunshine year-round.
  • Where should you install on your roof? Solar panels should ideally face north to receive the maximum sunlight. If you don’t have a north-facing roof, or your roof is flat, then an accredited installer may be able to install mounts that help angle the panels correctly.
  • How old is your roof? If you live in an old property, then ask your installer if they think the roof is appropriate for solar panels. In some cases, minor works may be needed on old properties to ensure the system is safe.

Larger solar systems produce more electricity and save you more on power, however they’re also more expensive. This is a balancing act between initial cost and future savings. If you’re looking for a system that can cover all or most of your electricity consumption, then you will need a 5kW system at least. If you’re just looking for a bit of bill relief, then it’s fairly standard to opt for a 3kW or 4kW system.

If you’re planning on leasing or selling your property, it’s important to understand that you usually won’t be able to take your solar system with you when you leave. Solar panels increase the value of a property however, and Realestate.com.au also found that renters are likely to pay more rent for a property with solar. That means solar could be a great property investment.

In Victoria, council approval is only required for solar panel installation if it is going on a heritage listed building or if it will be visible from the street or a public park.

In these cases you’ll require a planning permit, which can be applied for on the City of Melbourne website.

Origin Energy generally offers the best feed-in tariffs in Victoria. Not only do these providers have reasonably high feed-in tariffs, both also offers solar-specific deals tailored to households with solar panels. As always, some terms and conditions apply in order to receive a higher FiT rate.
