What makes Annandale different
Annandale is a family suburb on Townsville's southern side, developed through the 1990s and 2000s next to James Cook University and Lavarack Barracks. The homes are low-set block and brick with tile or Colorbond roofs on flat 700 m2 blocks, with very little shade. Postcode 4814 also covers Mount Louisa, Douglas, Cranbrook and Aitkenvale, which is why it has 10,939 rooftop systems.
- 10,939 rooftop systems in postcode 4814, with 652 added in the year to July 2026
- New 4814 systems averaged 11.0 kW last year
- 703 batteries installed across 4814 in the 12 months to July 2026
- Flat, unshaded blocks deliver 5.7 sun-hours a day, the highest of any hub we serve
- Ergon's regulated feed-in tariff of 13.4 cents/kWh makes exports worth more than in Brisbane
What postcode 4814 has already put on its roofs
Every accredited solar and battery install in Australia is registered with the Clean Energy Regulator by postcode. These are the numbers for 4814, which covers Annandale, along with Douglas and Mount Louisa.
Source: Clean Energy Regulator, postcode data for small-scale installations, data as at 31/07/2026. Counts are for the whole postcode, and the last 12 months will still rise because installers have a year to register certificates.

Solar savings estimate for Annandale
Pre-loaded with Annandale's own sun-hours, Ergon (regulated) tariffs and a typical local home. Slide the bill to match yours.
Preset for a typical Annandale home: Family home, ducted air running through summer, pool. Adjust to match yours.
Townsville air conditioning runs through the day from November to March, and pools are common. That lifts daytime use well above the Brisbane pattern, and a 10 kW system feeds it directly.

What we find on Annandale roofs
Annandale roofs are big, low and simple, with room for 10 kW on a north and west face. The concrete block construction typical of Townsville homes makes the roof-to-wall fixings robust for cyclone-rated mounting. Summer roof temperatures are the design issue: panel output drops about 0.35 percent for every degree above 25 degrees cell temperature, so we mount with good airflow underneath and favour panels with a low temperature coefficient.

Panel counts at 440 W per panel, about 2 m² each. We confirm the real count from satellite imagery before quoting.
| System | Panels | Roof area |

| 6.6 kW | 15 | about 30 m² |

What applies to a Annandale install
Council and network
There are no heritage overlays in Annandale, so the design is purely about yield and cyclone loading. The Townsville City Plan treats panels on an existing dwelling as accepted development. Every mounting system we use here is engineered for wind Region C. Ergon Energy runs the network: single-phase homes export up to 5 kW on a standard connection, and the regulated regional feed-in tariff of 13.4 cents applies. The streets closest to the Ross River sit in the flood overlay, so after the 2019 floods we mount inverters and batteries above the flood planning level there.
STC rebate in Annandale
Annandale is in STC Zone 2 (rating 1.536). With a 5-year deeming period, a 6.6 kW system earns about 50 certificates, roughly $1,950 at $39 each, and a 10 kW system about 76, roughly $2,964. 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 4814 added 703 batteries in the year to July 2026. We size the battery to your evening use, not the biggest unit on the truck.
Asked by Annandale homeowners
Does Townsville's heat reduce solar output?
Yes, a little. Panels lose about 0.35 percent per degree above 25 degrees cell temperature, so a 40 degree roof day costs roughly 10 percent. Townsville's extra sunshine more than makes up for it, and we specify panels with low temperature coefficients and mount them with airflow underneath.
What size system for a Townsville family home with air conditioning?
A 10 kW system is the common fit. New systems in 4814 averaged 11.0 kW in the year to July 2026, sized to run ducted air through the day and still export at the regulated tariff.
Where does the inverter go if I am near the Ross River?
Above the flood planning level, usually high on a garage wall or in the carport ceiling space. The 2019 floods showed why that matters, and Ergon's connection rules require it in the overlay.
