Solar in Caloundra

What makes Caloundra different

Caloundra is the southern end of the Sunshine Coast and the closest to our Ormeau depot. Postcode 4551 is enormous: it covers old Caloundra, Golden Beach, Pelican Waters, Currimundi, Little Mountain and the new Aura suburbs of Baringa and Nirimba. That mix runs from 1960s fibro beach houses to 2024 Colorbond estate homes, and the 21,541 systems installed here make it the busiest solar postcode we serve.

Why it works here
  • 21,541 rooftop systems in postcode 4551, the most of any postcode we install in
  • 1,568 new systems in the year to July 2026 and 1,321 batteries in the same period
  • Aura estate roofs suit a tidy 6.6 kW; Pelican Waters canal homes take 10 to 13 kW
  • Caloundra is 135 km from our Ormeau depot, the closest Sunshine Coast suburb we serve
  • Flat coastal blocks with low shading deliver the full 5.2 sun-hours a day

Aura households are typically out during the day, which keeps self-consumption near 30 percent and makes a battery attractive. Pelican Waters homes with pools follow a different pattern and suit 10 kW.

Roofs and homes

What we find on Caloundra roofs

The Aura estates have small, simple Colorbond roofs where 6.6 kW is the norm and 10 kW needs careful use of every plane; that is why the postcode average is a modest 8.9 kW. Old Caloundra and Golden Beach have older tin roofs on bigger blocks, quick to install and often able to take 10 kW. Pelican Waters canal homes are large tile roofs with pools and frequently three-phase. Beachside streets get marine-grade mounting.

Rules and rebates

What applies to a Caloundra install

Council and network

Old Caloundra has a small character area around the Bulcock Street precinct, but rooftop panels on existing homes remain accepted development throughout the Sunshine Coast Planning Scheme. The Aura estates carry Stockland design guidelines that permit solar but ask for tidy, plane-aligned layouts, which is how we install anyway. Energex serves the whole postcode; Aura feeders are solar-heavy, so single-phase export is held to 5 kW and dynamic connections are worth applying for. Golden Beach and Pelican Waters sit in storm tide overlays, affecting inverter height only.

STC rebate in Caloundra

Caloundra is in STC Zone 3 (rating 1.382). With a 5-year deeming period, a 6.6 kW system earns about 45 certificates, roughly $1,755 at $39 each, and a 10 kW system about 69, roughly $2,691. We claim it for you and take it off the quote.

Battery discount

The federal Cheaper Home Batteries Program cuts roughly 30 percent off the installed cost of a home battery, stepping down each year to 2030. Postcode 4551 added 1,321 batteries in the year to July 2026. We size the battery to your evening use, not the biggest unit on the truck.

Questions from Caloundra

Asked by Caloundra homeowners

Do the Aura design guidelines allow solar panels?

Yes. Stockland's guidelines permit rooftop solar and simply ask that panels align with the roof plane and avoid a patchwork layout. We design every Aura system that way and provide a rendered layout for the approval if you need one.

Why are new systems in Caloundra smaller than elsewhere?

Because so many are on compact Aura roofs. The postcode average of 8.9 kW reflects that. On an older Caloundra block or a Pelican Waters canal home we routinely install 10 kW or more.

I am in Golden Beach near the Passage. Any special considerations?

Two: salt spray, which means marine-grade mounting hardware, and the storm tide overlay, which sets the minimum height for the inverter and any battery. Both are standard for us and included in the quote.
