Home batteries in Sunshine Coast: the official numbers
More batteries than new solar systems have gone into Sunshine Coast homes in 2026: about 11 for every 10 new solar systems, so a lot of them are being added to homes that already have solar. These counts come from the Clean Energy Regulator's postcode data, as at 30 September 2026, for the postcodes listed on this page.
118,354 solar systems
Small-scale solar systems installed in Sunshine Coast postcodes, all years to 30 September 2026.
6,104 new solar systems in 2026
Installed from January to September 2026.
6,468 batteries in 2026
Installed from January to September 2026, and 10,154 since the federal Cheaper Home Batteries Program began in July 2025.
About 11 batteries per 10 new solar systems
In 2026 so far. With more batteries than new solar systems, many households are adding a battery to solar they already have.
Where Sunshine Coast homes are adding batteries
The Sunshine Coast postcodes with the most battery installations from January to September 2026 were 4551 (Caloundra, Caloundra West, Currimundi, Baringa and Aroona): 1,019; 4556 (Buderim, Sippy Downs, Forest Glen and Tanawha): 727; 4560 (Nambour, Bli Bli, Burnside and Mapleton): 647.
These are counts of installations, not a measure of price or quality. They show how much is happening locally, so it's worth asking neighbours who've been through it, and comparing at least two itemised quotes yourself.
The federal battery discount in Sunshine Coast
Sunshine Coast homes can get the federal Cheaper Home Batteries Program discount. For batteries installed from 1 May 2026 to 31 December 2026, each kWh of usable capacity earns 6.8 certificates, at a lower rate above 14 kWh. At $38 a certificate (installers trade them at the market price, which varies), that works out at:
- 10 kWh usable: 68 certificates, about $2,584
- 13.5 kWh usable: 91 certificates, about $3,458
- 20 kWh usable: 119 certificates, about $4,522
- 30 kWh usable: 154 certificates, about $5,852
- From 1 January 2027 the rate drops to 5.7 certificates per kWh, so the same 13.5 kWh battery would get about $2,888.
- The battery must be installed with new or existing solar, be able to join a virtual power plant (you don't have to join one), be on the Clean Energy Council's approved list and be installed by an accredited installer.
- Your installer normally takes the discount off the quoted price. Queensland's own Battery Booster rebate has closed.

Connecting a battery in Sunshine Coast
Sunshine Coast is on the Energex network. Energex sets the rules for connecting batteries, whichever retailer you buy power from.
Step 1: Approval first, even with existing solar
Adding a battery needs Energex approval before it's installed, like any new system. Your installer usually applies for you.
Step 2: The battery counts towards your limit
On a standard single-phase connection the total inverter capacity, solar and battery together, is limited to 10 kVA. A dynamic connection can allow up to 20 kVA, for example 10 kVA of solar and 10 kVA of battery inverter.
Step 3: Emergency backstop
New and replacement systems of 10 kVA or more need a generation signalling device, so the network can switch them off in a grid emergency. Check it's included in the quote.
On the 44c Solar Bonus Scheme?
Some older Queensland solar systems still earn the 44c feed-in tariff, which ends on 1 July 2028. You can keep it after adding a battery only if the battery doesn't run while the 44c system is generating (for example, it runs only at night or in a blackout) or the battery has its own separate connection. Otherwise you lose the tariff.
Replacing the inverter with a larger one also ends eligibility, and so does adding panels beyond the inverter's capacity. Ask installers how their design affects your tariff, and check with Energex before you go ahead.
Making a battery pay
Retailers in South East Queensland set their own feed-in tariffs, so the value of storing solar for the evening, rather than exporting it, depends on your plan. Compare offers once the battery is connected.
From 1 July 2026, retailers in Default Market Offer areas, including South East Queensland, must provide a Solar Sharer Offer with free electricity during three hours in the middle of the day (a smart meter is needed). A battery can store that energy for later. Joining a virtual power plant is another way some batteries earn credits: check the terms first.
Big batteries are taking over the evening peak
In the first half of 2026, nine large-scale battery projects were switched on across Australia, adding 7.1 GWh of storage. That's more than in all of 2025. They charge in the middle of the day, when solar is plentiful, and supply the evening peak, when the grid has traditionally relied on gas and coal. In the June quarter, battery supply in the evening peak rose 228% on a year earlier, according to AEMO.
Batteries now supply more of the evening peak than gas
In the September quarter of 2026, grid-scale batteries supplied 8% of electricity between 4 pm and 9 pm, more than gas (5.1%) for the first time in any quarter, according to AEMO. Batteries set the wholesale price in almost half of all trading intervals, up from 18% a year earlier. AEMO's sample data also showed that homes with rooftop solar and a battery drew about three-quarters less electricity from the grid in the evening peak than homes with solar alone.
What it means for power prices in Sunshine Coast
Wholesale electricity prices in the National Electricity Market averaged $63 per megawatt-hour in the September quarter of 2026, down 27% on a year earlier and the lowest September quarter since 2021, according to AEMO. In Queensland they averaged $61/MWh, down 15%. From 1 July 2026, the regulated reference price for household electricity also came down. Wholesale prices feed into retail bills slowly, so it takes time for changes to show up on yours.

What this means if you're buying a battery
Wholesale costs are only one part of a power bill, and network costs are still rising in some areas, so your own bill may not fall by as much.
Cheaper grid power also means each kilowatt-hour a battery replaces is worth a little less. Ask installers to base any savings estimate on your current tariff, not last year's, and check whether a time-of-use plan, a virtual power plant or the Solar Sharer Offer's free midday power changes the numbers.
The evening peak is still when the grid works hardest. A home battery covers your own evening use with solar you stored during the day, and that doesn't depend on what the wholesale market does. In AEMO's sample, homes with solar and a battery took about three-quarters less from the grid between 4 pm and 9 pm than homes with solar alone.
Keeping the power on in a blackout
Not every battery provides backup, and those that do may only cover some circuits. Ask which circuits stay on, how quickly the backup takes over, and whether your solar keeps charging the battery during a long outage.

What stays on depends on how the system is set up. Ask each installer which circuits are on backup, how quickly it switches over, and whether solar keeps charging the battery during a long outage.

Where the battery can go
The battery installation standard, AS/NZS 5139, limits where a battery can be installed. Among other places, it can't go:
- Inside a habitable room, such as a bedroom, lounge, kitchen or study
- In a ceiling space or wall cavity, or under a staircase
- On an evacuation or escape route
- Within 600 mm of a doorway, a window into a habitable room, or an appliance
Worth asking about in Sunshine Coast
- Close to the beach or the bay? Ask whether the battery and its inverter are rated for coastal sites, how far from the water they can go under the manufacturer's warranty, and whether they'll be sheltered from salt spray.
- In the hinterland around Maleny, Montville, Mapleton or Kenilworth? Ask whether the battery can run the home in a blackout, and how long it would last for the circuits you need. SWER lines also limit exports to 2 kW in total on Energex's basic connection.
- Building in a new estate? Ask your builder whether the switchboard and inverter will be battery-ready, so adding one later doesn't mean replacing them.
- All electrical work must be done by a licensed electrician. Ask for the installer's licence and accreditation details with the quote.

Frequently asked questions
Is there a battery rebate in Sunshine Coast?
Yes, the federal Cheaper Home Batteries Program, which your installer normally takes off the quoted price. Queensland's Battery Booster rebate has closed, so there's no extra state rebate.
How much is the discount on a 13.5 kWh battery?
For a battery installed by 31 December 2026, 91 certificates, or about $3,458 at $38 a certificate. The certificate price varies, so check the amount on each quote.
Can I add a battery to my existing solar in Sunshine Coast?
Usually, yes. It needs Energex approval, and the battery's inverter counts towards your connection limit. If you're on the 44c Solar Bonus Scheme, ask how the battery will be set up, because some setups end that tariff.
Will a battery keep my power on in a blackout?
Only if it's installed with backup. Many batteries can provide it, but some cover only selected circuits and some need extra equipment. Ask each installer exactly what stays on.
What size battery do I need?
Start with how much power you use from late afternoon until morning. Our guide and the rebate calculator show how capacity, solar size and the federal discount fit together.
