What makes Highfields different
Highfields sits 12 km north of Toowoomba on the range, a fast-growing suburb of large blocks, new homes and semi-rural properties. Postcode 4352 also covers Meringandan and the surrounding rural area. Blocks run from 1,000 m2 to several hectares, homes are modern and roofed in Colorbond, and three-phase supply is common because of sheds, pumps and ducted air.
- 9,311 rooftop systems in postcode 4352, with 626 added in the year to July 2026
- New 4352 systems averaged 11.6 kW last year
- 659 batteries installed across 4352 in the 12 months to July 2026
- Three-phase supply is common, lifting the Energex export cap from 5 kW to 15 kW
- Shed roofs and ground mounts allow true north at a 27 degree tilt, ideal for this latitude
What postcode 4352 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 4352, which covers Highfields.
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.

Preset for a typical Highfields home: Acreage home, shed, bore pump, ducted reverse-cycle. Adjust to match yours.
Pumps, workshops and ducted heating and cooling give Highfields homes a large daytime load. Self-consumption of 45 percent is realistic, which makes 13 kW pay back fast.

What we find on Highfields roofs
Highfields roofs are large modern Colorbond hips with clean planes, and the sheds next to them are often even better: open northern sky and simple mounting. We compare both in the design. Three-phase homes take 13 kW without hitting the export cap, and larger rural blocks suit ground mounts at the ideal 27 degree tilt for this latitude. Hail-rated panels are standard on every Toowoomba job.
- Housing era
- 1990s to 2020s homes, still expanding in the new estates

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 |
| 10 kW | 23 | about 46 m² |
| 13 kW | 30 | about 60 m² |
Acreage home, shed, bore pump, ducted reverse-cycle: 13 kW, self-consumption around 45%, three-phase common.
What applies to a Highfields install
Council and network
Highfields has no heritage constraints affecting houses, and the Toowoomba Regional Planning Scheme treats panels on existing buildings as accepted development. Ground mounts on rural residential blocks are also generally fine. Parts of the surrounding rural area sit in the bushfire overlay, which shapes cable routing. Energex serves Highfields with 5 kW export on single phase and 15 kW on three-phase, and up to 30 kW of inverter capacity on a standard three-phase connection.
STC rebate in Highfields
Highfields 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 4352 added 659 batteries in the year to July 2026. We size the battery to your evening use, not the biggest unit on the truck.
Asked by Highfields homeowners
House roof or shed roof for solar in Highfields?
Whichever has the clearer northern sky and the simpler structure, and often that is the shed. A cable run of 30 to 50 m back to the house switchboard is normal and included in our quote.
Can I install more than 10 kW?
Yes, on three-phase. Energex allows up to 30 kW of inverter capacity and 15 kW of export on a standard three-phase connection. For most Highfields acreage homes 13 to 20 kW is the right range.
What about frost and hail on the range?
Frost clears from the glass within an hour of sunrise and does no harm. For hail we specify panels certified to withstand 25 mm hailstones at 23 m per second, and severe storms are covered by home insurance.
