Yes, solar panels do increase home value — and in Australia, the evidence is stronger than ever. According to Domain’s 2025 Sustainability in Property Report, homes with solar panels sold for an average of $140,000 more than comparable homes without them. That is not a rounding error or a marketing claim.
That is real transaction data from across the country. So if you have been wondering whether going solar is worth it beyond just your electricity bill, the short answer is: absolutely. But the longer answer — which actually tells you how much, under what conditions, and what to watch out for — is what this article is here for.
Do Solar Panels Increase Home Value? Here Is What the Data Shows
When I first started researching whether solar panels increase home value in Australia, I expected to find a few modest studies with soft conclusions. What I found instead was a growing body of Australian-specific data that makes a compelling case, not just for solar as a savings tool, but as a genuine property investment.
The Cotality (formerly CoreLogic) report from 2025, conducted in partnership with the Commonwealth Bank of Australia, analysed data from six million Australian homes. The results showed that properties with solar panels commanded a 2.7% premium on their sale price, which averages out to around $23,100 per home nationally. That is money sitting on your roof right now — or money you are leaving on the table if you have not yet made the switch.
The Domain report goes further. It found that across all energy-efficient homes (those with solar, insulation, double glazing, and similar upgrades), houses sold for an average of 14.5% more than standard homes — a $118,000 difference at the median house price. For units, the premium was 12%, adding roughly $75,000 in value. These are not hypothetical figures; they are drawn from actual sales data.
What is particularly striking is the regional picture. In Melbourne, energy-efficient homes commanded a 23.8% premium. In Brisbane, it was 14.1%. Even in areas where solar adoption has been slower, the uplift is real and measurable.
Why Solar Panels Boost Home Value: What Buyers Are Actually Paying For
Understanding why solar adds value helps you make smarter decisions about your own system. It comes down to three things: financial certainty, lifestyle appeal, and future-proofing.
Financial Certainty: The Running-Cost Case for Solar’s Property Value
When a buyer purchases a home with solar already installed, they are essentially buying a built-in income stream and cost reducer. Electricity prices in Australia have risen significantly over the past decade, and there is no credible forecast suggesting they will fall. A buyer who moves into a solar home from day one is immediately spending less on power — sometimes hundreds of dollars less per month, depending on the system size and their usage patterns.
This is fundamentally different from a new kitchen or a freshly painted exterior. Those improvements make a home look nicer. Solar makes a home cost less to run. That ongoing financial advantage is exactly why buyers are willing to pay more upfront.
A 2023 study from the Australian National University found that renters would pay an additional $19 per week for a property with solar panels. Over 25 years, that additional rental income adds up to over $36,000. For landlords and investors, that is a meaningful return on installation costs.
Sustainability Appeal: Why Green Homes Sell for More
Australian buyers are increasingly motivated by sustainability — and not just in a vague, abstract way. The Domain report found that energy-efficient listings received 16.7% more buyer inquiries and sold 4% faster than comparable homes without those features. More eyes on your listing, a faster sale, and a higher price: that combination is rare in real estate.
When I spoke with a real estate professional in Sydney last year, she told me something that stuck with me: “Buyers used to see solar as a nice bonus. Now they see a home without it and ask what is missing.” That shift in buyer psychology is relatively recent, and it reflects a broader cultural change in how Australians think about energy, climate, and household running costs.
Future-Proofing: Solar Panels and the Long-Term Value of Your Home
Australia’s energy grid is undergoing a genuine transformation. Feed-in tariffs have compressed in recent years as solar uptake has surged — currently, around 38.7% of Australian households have solar panels installed. But the value of a solar home is not just about selling excess power back to the grid. It is about being ready for what comes next: electric vehicles, battery storage, induction cooking, and heat pump hot water systems.
A home with a well-sized solar system is already wired for this transition. A buyer who owns an EV, or plans to, sees immediate practical value in a property that can offset those charging costs. That forward compatibility adds a layer of value that standard property appraisal methods do not always capture — but buyers absolutely factor it in.
How Much Do Solar Panels Increase Home Value? A Practical Breakdown
The honest answer is: it depends. System size, age, quality, and location all play a role. Here is a comparison table that puts the main factors side by side.
Factor
Higher Property Value Impact
Lower Property Value Impact
System Size
10kW+ system
1.5kW–3kW older system
System Age
Installed within last 5 years
10+ years old, nearing warranty expiry
Battery Storage

Not included
Brand Quality
Tier 1 panels, reputable inverter
Unknown or discontinued brand
Installation Quality
CEC-accredited installer
No documentation, DIY
Location
High-sunshine state (QLD, WA, SA)
Cooler climate, limited sun hours
Warranties
25-year panel warranty, active
Warranties expired or non-transferable
A newer, well-installed 6.6kW system in Sydney, for example, has an estimated net present value (NPV) of future savings of around $24,400 — meaning that is the lump sum a rational buyer should theoretically be prepared to pay extra for that system, accounting for the time value of money. A 10kW system in the same location tips that NPV above $40,000.
But here is something most articles do not tell you: the age depreciation curve on solar is steep. A 12-year-old 1.5kW system installed during the early Feed-in Tariff gold rush is not an asset. Panels degrade at roughly 0.5%–1% per year in output. An old, undersized system might actually deter savvy buyers who know they will need to replace it soon. The value of solar is not fixed — it decays with the system, and accelerates when warranties have expired.
Do Solar Panels Increase Home Value for Landlords and Investors?
If you own an investment property, the question of whether solar panels increase home value takes on a slightly different shape — it is yes, but on two specific fronts: rental yield and vacancy rate.
Tenants are increasingly prioritising energy efficiency when choosing a rental. Surveys consistently show Australian renters would pay between $10 and $19 more per week for a solar-equipped property. At $19 per week, that is an additional $988 per year. On a 25-year hold, with modest annual adjustment, that income stream represents a significant return over and above the system’s installation cost.
Beyond the rent premium, a solar-equipped rental typically spends less time vacant. That hidden cost — a property sitting empty for an extra two to four weeks between tenancies — can easily exceed $2,000 per year in lost income. Solar helps prevent that.
There are also potential tax implications. Depending on how your investment is structured, the installation cost and depreciation of a solar system may be claimable. Always confirm this with a qualified accountant, as individual circumstances vary.
The Investor’s Perspective: Calculating Solar’s Added Home Value
To make this concrete, consider a standard 6.6kW system installed on a rental property in Queensland. After government rebates and STCs, the net installation cost sits at roughly $5,500–$7,000. The rental premium of $19 per week generates $988 per year in additional income. That means the system effectively pays for itself through rent increases alone in around six to seven years — and then continues delivering that premium income for another fifteen to eighteen years before the panel warranty expires. That is a return profile that compares favourably with most other property improvements, and it does not require you to tear out a bathroom or repaint every decade.
What Adds Even More Property Value Than Solar Panels Alone
Solar is powerful, but it is more powerful as part of a broader energy-efficient home package. The Domain data makes clear that whole-home energy efficiency — not just panels on the roof — is where the real premium lives.
Homes with solar paired with quality insulation, a solar hot water system or heat pump, double-glazed windows, and north-facing orientation sold for a combined premium of up to 23.8% in Melbourne. That premium reflects what buyers want: a home that is comfortable year-round, costs little to run, and is future-ready.
If you are planning a renovation or property upgrade and want to maximise both liveability and resale value, combining solar with other energy efficiency improvements is the most effective strategy. If you are not sure where to start with that kind of integrated upgrade, it is worth seeking expert renovation assistance to plan it properly — piecemeal improvements rarely deliver the same return as a coordinated energy overhaul.
Buying a Home with Solar Panels: What to Check Before You Pay the Premium
This is the side of the conversation that most solar articles skip. If you are in the market for a home and the listing mentions solar, you need to ask the right questions before you factor it into your offer price.
How Old Is the System?
Solar panels are typically warranted for 25 years, but their actual performance degrades from day one. A system installed in 2015 has already lost somewhere between 5% and 10% of its original output. Ask for the installation certificate or the CEC approval paperwork.
Are the Warranties Still Valid and Transferable?
Product warranties and performance warranties are different. A product warranty covers manufacturing defects; a performance warranty guarantees the panel will still produce a certain percentage (often 80%) of its rated output at a specified point in its life. Check whether these warranties are transferable to a new owner — not all manufacturers allow this automatically.
Who Installed It?
Installation quality matters as much as the hardware. A system with tier-1 panels but a poor installation can underperform, develop faults, or present safety issues. Ask whether the installer was CEC-accredited. If there is no documentation available, treat that as a yellow flag.
What Size Is It?
A 1.5kW system from 2010 is not the same thing as a 10kW system from 2023. Make sure you understand the system’s actual generating capacity relative to the home’s power consumption. Ask for recent power bills or monitoring data to see what the system is actually producing.
Three Mistakes That Stop Solar Panels from Increasing Your Home Value
Most homeowners install solar correctly and benefit from it. But I have seen a surprising number of cases where poor decisions before or after installation wiped out a large chunk of the value uplift. If you genuinely want solar panels to increase your home value, these are the pitfalls worth knowing about before you spend a dollar.
Choosing Price Over Quality
The Australian solar market has become crowded with cheap imported systems of variable quality. On paper, a $2,500 solar deal sounds like a win. In practice, panels from unknown manufacturers with thin or unenforceable warranties can degrade faster, fail earlier, and come with no meaningful support when something goes wrong. A savvy buyer looking at your property will notice the brand. An appraiser who knows the market will factor it in.
Premium tier-1 panels — brands with a track record, a physical presence in Australia, and warranties that are actually honoured — hold their value better. The gap in installation cost between a budget system and a quality one is often surprisingly small once you account for rebates. The gap in long-term value and reliability is significant.
Not Monitoring System Performance
This one surprises people, but I think it is genuinely important: a solar system that is silently underperforming for years costs you more than you realise. Inverter faults, partial shading from a new neighbouring structure, degraded panels, or wiring issues can reduce output by 20–30% without triggering any obvious alarm. You lose that money quietly on your power bills, and you also lose the right to make a confident claim about system output when you eventually sell.
Getting into the habit of checking your monitoring app monthly — or having a professional inspection every few years — keeps you informed and means you can confidently tell buyers exactly what the system produces.
Installing Solar and Then Ignoring the Grid Connection Agreement
Many homeowners who installed solar during the peak Feed-in Tariff period (2009–2015) locked in rates of 44–60 cents per kWh for export. Those grandfathered agreements can be transferred to new owners in some states, subject to the network’s terms. If you are selling a home with one of these legacy tariffs still active, that arrangement has real financial value — and is worth researching and communicating clearly to potential buyers. Losing a premium FiT through a clumsy property transfer is an avoidable mistake that I have seen cost sellers thousands of dollars in buyer negotiating leverage.
When Solar Panels Do Not Increase Home Value: The Honest Caveats
The data is compelling, but I want to be straight with you: solar panels do not automatically increase home value dollar-for-dollar in every property and every market.
In some locations, particularly lower-priced regional markets or areas where electricity costs are lower, buyers may not be willing to pay a full premium for solar. The value uplift in these areas is real but more modest.
There is also the overimprovement risk. If your home’s value in its street is already at or near the ceiling for that suburb, spending $15,000 on a premium solar-and-battery setup may not return the full cost in a resale scenario. Improvements should always be proportionate to the property’s base value and likely buyer pool.
And finally, a point worth repeating: an old, undersized, or poorly installed system can actually work against you. A buyer who knows what they are looking at may factor in the cost of removal and replacement rather than adding a premium for a struggling system.
Making the Most of Solar Panels and Their Impact on Home Value
If you have read this far and are weighing up whether to install solar, upgrade an existing system, or factor it into a renovation, the timing has never been better. Solar panels can increase your home value meaningfully — but only when the system is sized right and installed properly. Australian federal and state government incentives — including small-scale technology certificates (STCs), state battery rebates, and interest-free loan programs in some states — can meaningfully reduce the upfront cost.
The sweet spot for value maximisation is a system in the 6.6kW–10kW range, installed by an accredited installer, with a reputable tier-1 brand, ideally paired with battery storage. That combination ticks every box that buyers and appraisers are looking for in 2026 and beyond.
If you are approaching this as part of a broader home improvement project, there are home makeover courses available that cover exactly how to sequence and prioritise upgrades like solar, insulation, and efficient appliances for maximum return on investment.
Frequently Asked Questions
How much does solar add to property value in Australia?
Based on 2025 data, solar-equipped homes sold for an average of $140,000 more than comparable homes without solar across Australia, though this varies significantly by location, system size, and overall home quality.
Do solar panels make a house easier to sell?
Yes — energy-efficient homes with solar attracted 16.7% more buyer inquiries and sold 4% faster on average, according to Domain’s 2025 Sustainability in Property Report.
Does a solar system increase my home’s value if it is old?
Not necessarily. A system older than 8–10 years with expired warranties may actually reduce buyer confidence. The value addition depends heavily on the system’s age, condition, and remaining warranty coverage.
Do solar panels add value to a rental property?
Yes, in two ways: renters are willing to pay up to $19 more per week for a solar home, and solar properties tend to experience lower vacancy rates, both of which improve overall rental yield.
Does battery storage add even more property value than solar alone?
Research suggests that homes with both solar and battery storage attract a higher buyer willingness-to-pay than solar alone, as battery systems offer energy independence and backup power — factors increasingly valued by Australian buyers.
Where to Go from Here
The question of whether solar panels increase home value has a clear answer in 2026 Australia: yes, measurably, and in many cases significantly. But the size of that uplift depends on doing it right — the right system, the right installer, the right timing, and ideally as part of a broader energy-efficient home strategy.
If you are planning to sell in the next few years, or simply want your home to work harder for you financially, solar is one of the most evidence-backed improvements you can make. The data does not just support it — it makes a compelling case for acting sooner rather than later.
