What makes East Toowoomba different
East Toowoomba is the city's heritage heart, the grid of tree-lined streets between Queens Park and the escarpment. The homes are Federation and interwar timber houses on generous blocks, many heritage listed, under mature camphor laurels and plane trees. It sits at about 690 m elevation, so panels run cooler and more efficiently than on the coast, and the clear western sky delivers 5.5 sun-hours a day.
- 19,713 rooftop systems in postcode 4350, with 1,211 added in the year to July 2026
- New 4350 systems averaged 11.3 kW last year
- At 690 m elevation panels run cooler, and cooler panels produce more per rated watt
- Deciduous street trees drop their leaves in winter, when Toowoomba heating loads peak
- 1,070 batteries installed across 4350 in the 12 months to July 2026
What postcode 4350 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 4350, which covers East Toowoomba, along with Centenary Heights, Glenvale, Kearneys Spring, Mount Lofty, Newtown and Westbrook.
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.

What we find on East Toowoomba roofs
The tin roofs here are steep and broken into several planes, so we typically split a 6.6 kW array across a north and a west face and keep the street elevation clear. Deciduous trees drop their leaves in winter, which helps the winter output that matters most in a Toowoomba heating season. Older homes often have ceramic fuse boards that need upgrading before Energex will connect, and we quote that up front.
- Housing era
- 1890s to 1940s Federation and interwar timber homes
- Roof material
- Corrugated tin, some slate-look Colorbond replacements
- Roof pitch
- Steep, 25 to 35 degrees, with gables and dormers
- Typical block
- 800 to 1,200 m2, level or gently sloping
- Home type
- Detached character homes, some large villas
- Shading
- Heavy from deciduous street trees in summer, lighter in winter
Panel counts at 440 W per panel, about 2 m² each. We confirm the real count from satellite imagery before quoting.

What applies to a East Toowoomba install
Council and network
Much of East Toowoomba sits within the Toowoomba Regional Planning Scheme's heritage overlay and character areas, and many individual houses are on the local heritage register. Solar panels on an existing house are still accepted development, but on a listed home we place panels on rear and side planes and keep the street facade unchanged. Energex serves Toowoomba with the standard 5 kW single-phase export cap. Older switchboards need upgrading to meet the connection standard.
STC rebate in East Toowoomba
East Toowoomba 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 4350 added 1,070 batteries in the year to July 2026. We size the battery to your evening use, not the biggest unit on the truck.
Asked by East Toowoomba homeowners
Can I put solar on a heritage-listed home in East Toowoomba?
Yes. Panels on an existing house are accepted development, even in the heritage overlay. We design for the rear and side planes so the street-facing facade stays exactly as it is, which keeps council and neighbours comfortable.
Do hailstorms damage solar panels in Toowoomba?
Quality panels are tested to withstand 25 mm hail at 23 m per second, and we specify panels with that certification for Toowoomba. Severe hail is covered by your home insurance, and panels typically fare better than skylights and tiles.
Does the cold help or hurt solar here?
It helps. Panels lose output as they heat up, and Toowoomba's cooler air keeps them closer to their rated efficiency. A clear winter day at 690 m produces well, and frost clears off the glass within an hour of sunrise.
