One in three Aussie homes now have rooftop solar, with the Australian Government reporting an average saving of $1,500 per year per household with them installed. Stats like that create a strong case for getting solar, but it doesn’t tell you what it could do for you.
For many Victorian homes and businesses, solar can be very worthwhile in the right situation. But is it worth getting solar panels in Victoria for your property? These are the main factors that can help you work it out.
TL;DR: Are solar panels worth it?
- Where the roof is suitable and it’s matched to a suitable system, solar can be very worthwhile for Victorian properties.
- The potential return from solar is mainly from buying less power from the grid, not earning money through feed-in tariffs.
- Depending on rebates, a solar system in Victoria could pay for itself within three to five years.
- Properties with heavy shading or with low electricity use may have different paybacks than average.
- A solar quote is the most useful way to compare costs, generation, self-consumption, tariffs and export limits specifically for your property.
How much do solar panels cost in Victoria?
Solar prices can vary quite widely depending on the system size, equipment and what’s involved in installing it on your property. Based on figures from the Australian Bureau of Statistics, Australians paid an average of $836 per kilowatt of new solar capacity in 2024–2025 after Federal Government Small-Scale Technology Certificate support. At that rate, a 6.6kW system works out to be around $5,500.
While the national average gives you an idea of potential savings, your actual quote may be quite different. CHOICE shows how wide the price can range depending on system size alone one the STC discount has been applied:
| Solar System Size | Who It Often Suits | Estimated Installation Cost |
|---|---|---|
| 5 kW | Smaller home with lower electricity use | $4,500 to $8,000 |
| 6.6 kW | Average home with moderate electricity use | $5,500 to $9,000 |
| 10 kW | High-use home, all electric property or small business | $8,000 to $13,000 |
There are also state-by-state rebates available that may impact the end cost.
Solar rebates available in Victoria as of July 2026:
- Federal STC Discount: Under the Australian Government’s Small-Scale Renewable Energy Scheme, eligible households can receive an upfront discount on their solar installation, usually taken off the quoted price.
- Victorian solar rebate: Where eligible households can receive a rebate of up to $1,400, plus an optional interest-free loan of up to $1,400. You do need approval before the system is installed.
Federal and state solar rebates and programs do change from time to time, so it’s always best to check what you’re eligible for before going ahead with an installation.
How do solar panels actually save you money?
The simple answer to how solar panels save you money is that by having a system, you buy less electricity from the grid. In reality, this helps you in two ways:
1. By using your own solar power.
Using the power your solar panels generate is where most of the savings come from. For the most value, you can shift appliance use that takes more power, like running the dishwasher, washing machine, dryer or pool pump, to daylight hours. Every bit of power you make and use is less you buy from the retailer.
Bigger isn’t automatically better for saving money with solar. For your solar system to actually save you money, your system needs to suit how much electricity you use and when you use it. That’s how you get a good return on investment.
2. By exporting excess power to the grid.
If your panels generate more electricity than you’re using, the extra power can be sent to the grid. Depending on your retailer and power plan, you may get a feed-in tariff credit on your bill, helping reduce your overall cost. While it’s still useful, they’re usually much lower than the cost of buying electricity from the retailer. In most cases, it means using your solar power is worth more than exporting it. This is where moving more energy-fuelled tasks to the daytime can help.
What is the average solar payback period?
How long it takes for your electricity savings to cover what you spent on the system is called the solar payback period. In our 15+ years of solar installation in Melbourne, the properties that see the fastest payback tend to use more electricity during the day with a properly sized system.
Solar Victoria estimates a home solar system receiving the Victorian rebate could pay for itself within three to five. Without the rebate, it’s close to seven to nine years for a grid-connected system. For example, if your system costs you $6,000 after discounts and saves you around $1,500 a year, your payback period would be roughly four years.
So, is solar worth it based on the payback period? It can be, depending on the system price, electricity use, daytime consumption and how much power is exported. It also matters how long you plan to stay in the property.

What can affect your return on solar panels?
The same solar system can give two properties very different results. What can affect your return on your solar panels can include:
- How much electricity you use. The more power you use, the more opportunities there are for solar to help reduce what you buy from the grid.
- When you use electricity. Someone working from home may use more solar as it’s generated, while a household that’s empty until the evening may export more during the day and buy electricity back after sunset.
- System size and expected generation. A 10kW system may not deliver a proportionally better return than a 6.6 kW system if much of the extra power cannot be used or exported.
- Roof direction, pitch and shading. Shade from a chimney, tree or nearby building can reduce how much sunlight reaches the panels and may affect how the system needs to be configured.
- Electricity tariffs and export limits. Electricity prices, feed-in tariffs and export limits affect how much you save. As exported power usually earns less than the cost of buying electricity, using more solar onsite tends to deliver greater value.
- Equipment and installation. Look beyond the headline performance warranty and check the product warranty, Australian manufacturer support and installer’s workmanship coverage separately. Teaslec, for example, backs its solar installations with a 25-year workmanship guarantee.
Even without a north-facing roof, solar may still be worthwhile.
While north-facing roofs tend to receive the most sunlight, solar panels can also work on east and west-facing roofs. Solar Victoria reports east or west-facing panels on a 20-degree roof produce up to 15% less electricity on average than north-facing panels, but may generate more power earlier in the morning or later in the afternoon. Planning your energy usage can make solar still worth it.
When Solar Panels Are Most Likely to be Worth It
Solar panels are most worthwhile for properties that get good sunlight, use enough electricity and are kept long enough for the system to recover the upfront cost. This can look a little different for homes and businesses.
“You can’t say that every single home and business will find solar worthwhile. But for the most part, generally speaking, having solar panels installed is rarely something you hear people say they regret. While there is that upfront cost, there are government programs that can help reduce it, and the ongoing benefits are typically worth it alone.”
For Victorian homes:
For a homeowner, solar may be a good fit if:
- Your household has moderate to high electricity bills.
- You use power during the day or can schedule appliances to run while your panels generate electricity.
- You have or plan to use electric appliances, such as electric hot water, stoves or even an electric vehicle.
- Your roof is in good condition and receives plenty of sunlight.
- You expect to stay in the property beyond the estimated payback period.
Scenario 1: Meet Jenny:
Jenny works from home several days a week and runs the washing machine, dishwasher and air conditioning during the day. She has an unshaded roof, plans to add an EV and expects to stay in the property long term. As she could use a large share of the solar power as it’s generated, solar is more likely to deliver a worthwhile return.
Scenario 2: Meet Tom:
Tom lives alone, has low electricity bills and is away most days. His roof is heavily shaded, needs repairs and he plans to move within a few years. With limited daytime use and less time to recover the upfront cost, installing solar may not make financial sense for him right now.
For Victorian businesses:
Businesses can often benefit from solar if:
- Most of your electricity is used during the day.
- Equipment, cooling, lighting or machinery creates steady daytime demand.
- There is enough suitable roof space for the system you need.
- The business owns the property or has enough time remaining on the lease to recover the costs.
For example, a workshop running machinery, compressors, lighting and cooling throughout the day may use much of its solar power as it is generated. If it also has a large, unshaded roof and expects to remain at the premises long term, solar could help reduce a meaningful portion of its operating costs.
When Teaslec assesses a home or business, our team compares electricity bills and smart meter data with the roof layout, shading, export limits and future plans. This helps determine how much solar power the property could realistically use instead of recommending a standard system based on the bill alone.
So, are solar panels worth it in Australia, really?
Yes, solar panels are worth it for many Australian homes and businesses. The key points to remember are:
- Solar tends to deliver stronger returns when more of the power generated is used onsite (during the day).
- Victorian rebates may reduce the upfront cost for eligible properties and shorten the payback period.
- System design, installation quality and after-sales support can matter just as much as the equipment selected.
For the strongest returns, you want a system designed around your property, electricity use and future needs. This is where a tailored assessment outlining your personal expected costs, generation, savings and payback period can help you do the maths before you commit.
