What makes Toowong different
Toowong is 4 km west of the CBD, spread between the river and the foothills of Mount Coot-tha. The flat streets near the village are apartments and older cottages, while the hillside streets have larger homes on sloping blocks that catch the afternoon sun but sit in the shadow of the mountain by late afternoon. We install across both, and the design changes with the terrain.
- 1,676 rooftop systems in postcode 4066, with 117 added in the 12 months to July 2026
- New 4066 systems averaged 11.9 kW last year, driven by EV charging
- 195 batteries installed across 4066 in the year to July 2026
- North and east-facing hillside roofs avoid the Mount Coot-tha afternoon shadow
- Apartment roofs off Sherwood Road are large, flat and mostly unshaded
What postcode 4066 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 4066, which covers Toowong.
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 Toowong roofs
On the western side of Toowong the mountain removes the last hour of afternoon sun, which favours north and east-facing arrays. Homes on the eastern flats have no such problem and can use a west face for afternoon output. Apartment buildings have large flat membrane roofs and are good candidates for shared solar, but need body corporate approval and a metering plan.

What applies to a Toowong install
Council and network
Toowong has scattered Traditional building character overlay areas and several heritage-listed homes, so we check each address. Panels on an existing dwelling remain accepted development. Apartment roofs are community title and need body corporate consent, plus a decision on whether the system feeds common power or individual units. Energex serves the suburb, with 5 kW static export on single phase and dynamic connections available for larger systems.
STC rebate in Toowong
Toowong 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 4066 added 195 batteries in the year to July 2026. We size the battery to your evening use, not the biggest unit on the truck.
Asked by Toowong homeowners
Does Mount Coot-tha affect solar in Toowong?
On the western streets it cuts the last hour or so of afternoon sun, especially in winter. We account for it in the shade model and favour north and east-facing planes there. Homes on the river flats are unaffected.
Can our apartment building install solar?
Yes, with body corporate approval. The simplest option feeds common-area power such as lifts and lighting. Systems that share output between units are possible with embedded network metering. We can present options to your committee.
How much does solar cut a Toowong power bill?
A 10 kW system here produces around 14,000 kWh a year. For a household using 40 percent of that directly at 32 cents and exporting the rest at 6 cents, that is roughly $2,300 a year off the bill.
