Long story short

Solar panel costs vary depending on your setup

Your system size, panel quality, and your installer can all shift the final price around. Adding on a battery and extra features can also bump it up further.

Victorian rebates and schemes can help cut your upfront costs

Between the SRES, state rebates, and battery incentives, many Victorian homes can shave thousands off their new solar systems.

Solar can pay itself back surprisingly fast

Many Victorians can see their solar panels paid back within four to seven years (depending on their system size).

How much does it cost to install solar panels in Victoria?

Installing solar panels in Victoria costs $4,800 to $12,000 on average (see table below), without government rebates. While bigger systems will push up the final cost, government incentives can also affect your out-of-pocket costs once they’re up and running.

To give you a ballpark idea of installation costs when switching to solar, check out the table below (which includes potential solar panel rebate savings) to see if solar could fit in with your near-future plans.

Factors that affect solar panel installation costs

Size of panels

The size of your solar panels not only influences your upfront costs, but it also affects how much energy your home can generate and how that plays into your everyday energy consumption and electricity bills. Doing some research into your current energy usage can help you figure out what size system will best pull its weight. It’ll also mean you aren’t paying for more panels than you need, dragging your payback period longer than necessary.

Quality of solar panels and add-ons

Not all solar panels are created equal and while cheaper options can be tempting, they might compromise quality, performance, or longevity in exchange for affordability. You could also find that some cheaper solar panels aren’t eligible for certain rebates, reducing their financial benefit in the long run.

Your installer also matters, too, with reputable installers often coming with a higher fee.

While it’s important to find panels that are worth their value, there can also be add-on features that affect your system costs. Features like microinverters or 3 Phase inverters might suit certain homes, but they’ll add more onto the final system price.

Smart monitoring device

While installing your solar panels, your installer might offer a smart monitoring device as part of the setup. These devices pull data from your smart meter and inverter to show you how much solar power you’re generating, using, and exporting. They can cost up to $400 but can work out in your favour if you like to keep tabs on your energy habits, system performance, and panel health (or if you just enjoy seeing your panels hard at work).

Adding a battery

For some homeowners, solar panels alone are enough. But others might want the whole kit and caboodle, including a big home battery to store up all that excess sunshine and reduce their dependency on the grid. It’s worth noting that the batteries will add a decent chunk to your upfront costs. Because they aren’t as widely adopted as solar panels, prices are still relatively high in comparison. For example, a 10kW battery for a 6.6kW panel system could add an extra $8,900 to your installation bill.

Are solar rebates available in Victoria?  

Victoria is lucky to have a range of solar rebates to help most locals switch to the solar side. Here’s a quick rundown of what federal and state government rebates could be available for you.

Are solar panels worth it? 

For many homes, rooftop solar is worthwhile. From possibly lowered energy costs and reduced reliance on the main grid to environmental benefits and added value to your home, solar can hit a range of targets for homeowners in Australia.

Pros

Bill savings

While solar panel prices can seem high, the savings can often be seen fairly quickly. Many Melbourne homes can save an average of $1,073 on their annual bills by switching to solar. For a standard 6.6kW panel system, that could mean savings of between $300–$500 per quarter.

Short payback period  

Solar panels generally have a relatively short payback period. For a typical 6.6kW panel system, you could see your installation costs paid back within four to seven years. Considering most panels last about 25 years, that’s a lot of time to let those savings stack up.

Less reliance on the grid

While solar panels can make a nice dent in your energy bills, another advantage is that they can help reduce your home from fluctuating grid prices and peak-time network stress. On top of its environmental benefits, solar-powered homes can also support local grid stability if they’re connected to virtual power plants.

Cons

Upfront costs

Even with rebates and schemes, solar panel systems can still come with high price tags and installation costs. It’s a big financial decision to make – especially if you go all out by adding a battery.

Output is weather-dependent  

Victoria’s cold winters and unpredictable weather conditions can affect how much energy your panels generate throughout the year. This can affect your solar energy generation, how much you rely on the grid, and your final bills.

Falling feed-in tariffs

As solar becomes more common, feed-in tariffs have started to drop. With schemes like the SRES ending in 2030, many homes will need to focus on changing up their energy habits to self-consume their solar rather than exporting it to the grid (which doesn’t suit everyone).

Helpful tip

Getting a few free quotes from authorised solar companies isn’t just an easy way to compare panel quality, inverters, product warranty, and installation standards; it’s also a required step in the Victorian solar rebate process. You’ll need your quote to know if you’re eligible, so don’t dive in headfirst and pay any deposits until you get the all-clear from the government.
