The Solar Divorce: Why Aussie Buyers Are Walking Away from “Naked” Homes

Imagine finding the perfect home: the right bedrooms, renovated kitchen, great backyard and ideal location.

Then you look at the roof.

No solar panels. No modern inverter. No battery.

For energy-conscious Australian buyers, this increasingly means higher ongoing electricity costs and another major upgrade to consider after settlement.

Welcome to the “Solar Divorce” where buyers are beginning to look beyond kitchens and floorplans and consider whether a property is equipped for Australia's changing energy market.

The Rise of the “Naked Home”

A property without solar might be considered a “naked home” completely dependent on grid electricity with little protection from changing energy prices.

Location and lifestyle still matter, but running costs are becoming a bigger part of affordability.

The Australian Energy Regulator's 2026–2027 Default Market Offer includes residential usage rates above 33 cents per kWh in some NSW distribution areas, with some time-of-use peak rates considerably higher.

That creates a noticeable difference between two otherwise similar properties:

Home A: No solar or battery and greater reliance on grid electricity.

Home B: Modern rooftop solar and battery storage designed to maximise self-consumption.

For some buyers, Home B isn't simply greener. It offers greater control over future household energy costs.

Solar Is Becoming Part of the Property Conversation

Solar doesn't guarantee a higher sale price. Property values depend on location, demand, system quality, age and many other factors.

However, a well-designed solar and battery system can give sellers another attractive feature to promote particularly when buyers are comparing similar properties.

The economics of battery installation have also changed.

Australia's Cheaper Home Batteries Program provides an upfront discount on eligible battery systems. Importantly, changes introduced in May 2026 made support tiered according to usable battery capacity, encouraging households to choose appropriately sized systems rather than simply installing the largest battery possible.

This means buyers increasingly shouldn't ask only:

“Does this house have solar?”

They should also ask:

“How much electricity will this house still need to buy from the grid?”

Buyers Beware: The “Legacy Solar” Trap

Panels on the roof don't automatically mean a home has a good energy system.

Many Australian properties have older solar systems installed years ago. Some continue to perform well, while others may have undersized arrays, ageing inverters or equipment poorly suited to today's electricity needs.

Before buying a solar-equipped property, check:

• System age: When were the panels and inverter installed, and are warranties still active?

• System size: Is it large enough for modern household consumption, particularly if you plan to add an EV, battery or electric appliances?

• Performance: Ask for recent electricity bills and solar monitoring information.

• Battery compatibility: Can the existing system support battery storage without significant redesign?

• Documentation: Request installation records, warranties, equipment details and available compliance paperwork.

  
  

Solar panels sitting on a roof are only valuable if the system is working properly and suited to the household.

What Sellers Should Do Before Listing

Planning to sell within the next 12 months? You don't necessarily need to install the biggest solar-and-battery package available.

Instead, make your property's energy performance easy for buyers to understand.

Get Your System Checked

If your solar system is several years old, consider having it inspected. Address faults and make sure monitoring is operating correctly.

Gather Your Documentation

Keep your installation documents, warranties, system specifications, monitoring information and recent electricity bills together.

If those bills demonstrate low grid consumption, they can help buyers understand the practical benefits of the system.

Don't Oversize the Battery

Battery sizing should reflect solar generation, electricity consumption and household usage patterns.

Under the current federal program, incentives introduced from May 2026 are tiered by usable battery capacity. This makes correct sizing increasingly important.

Bigger isn't automatically better. The right system is better.

Use Properly Accredited Installers

If you're upgrading before selling, make sure the installation meets current Australian requirements.

Solar Accreditation Australia (SAA) administers installer accreditation, and equipment used to access government incentives must meet applicable eligibility requirements.

Good installation and complete documentation can provide greater confidence to both sellers and future homeowners.

Why Batteries Change the Equation

Solar produces most of its electricity during daylight hours, but many households consume significant energy later in the day when solar generation falls.

A battery allows excess daytime solar to be stored and used later rather than relying entirely on grid electricity.

Depending on the system and electricity tariff, battery storage may also provide benefits such as:

• Greater solar self-consumption

• Reduced exposure to peak electricity prices

• Backup capability with appropriately configured systems

• Potential Virtual Power Plant participation

  
  

A battery isn't automatically financially suitable for every household. Its value depends on electricity consumption, solar generation, tariffs, system cost and how the household uses energy.

But for buyers looking at the long-term running costs of a property, solar plus battery storage can offer greater energy independence.

The New Property Question: “What Will This Home Cost Me to Run?”

Australian buyers aren't going to stop caring about location, kitchens, bedrooms or backyards.

They're simply adding another question:

What will this property cost me to run?

A home heavily dependent on grid electricity may look different when compared with a similar property capable of generating, storing and managing much of its own energy.

That doesn't make every “naked home” a bad investment.

But it does mean that solar, batteries and household energy performance deserve a place alongside building inspections, insurance, council rates and other costs when assessing a property's true affordability.

For many Australians, the energy system is becoming part of the home itself.

Make Your Property Energy-Ready

Whether you're buying, selling or simply preparing your home for the future, don't choose a solar or battery system based on size alone.

Choose one designed around the property's actual energy needs.

Smart Energy Market helps Australian homeowners compare solar and battery options based on their property, electricity consumption and energy goals.
