What makes Mount Lofty different
Mount Lofty sits on the eastern rim of Toowoomba, where the range drops away to the Lockyer Valley. The homes are older and larger than most of the city, on steep, treed blocks with views east, and many are heritage-era timber houses. The escarpment edge gets more morning fog and cloud than the western suburbs, and the design accounts for it with a preference for north and west planes.
- 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
- 1,070 batteries installed across 4350 in the 12 months to July 2026
- North and west planes catch the clear afternoon sun once the escarpment fog lifts
- Steep tin roofs install without tile breakage and shed hail and storms quickly
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 Mount Lofty, along with Centenary Heights, East Toowoomba, Glenvale, Kearneys Spring, 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.

Preset for a typical Mount Lofty home: Large older home, ducted reverse-cycle, home office. Adjust to match yours.
Big, older homes on the escarpment take real energy to heat through a Toowoomba winter. Daytime reverse-cycle use lifts self-consumption to about 40 percent.

What we find on Mount Lofty roofs
Mount Lofty blocks slope east toward the view, and the largest roof plane often faces east with it. We model each plane and usually recommend the north and west faces, which catch the clear afternoon sun after the morning fog lifts. Mature trees are common, so optimisers are used where a string catches shade. The steep tin roofs are quick to fit but need edge protection, which we bring as standard.
- Housing era
- 1900s to 1960s timber and brick homes, some 1990s rebuilds
- Roof material
- Corrugated tin and Colorbond, some concrete tile
- Roof pitch
- Steep on the older homes, 25 to 35 degrees
- Typical block
- 800 m2 to 2,000 m2, sloping east
- Home type
- Large detached homes on hillside blocks
- Shading
- Moderate to heavy, mature trees and neighbouring homes uphill
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 |

Large older home, ducted reverse-cycle, home office: 10 kW, self-consumption around 40%.
What applies to a Mount Lofty install
Council and network
Parts of Mount Lofty sit within the heritage overlay and character areas of the Toowoomba Regional Planning Scheme, and several homes are locally listed. Panels on an existing house remain accepted development; we keep the street elevation clear on listed homes. The escarpment edge falls within the landslide hazard and bushfire overlays, which affect ground-level equipment and cable routing. Energex serves the suburb with the standard 5 kW single-phase export cap.
STC rebate in Mount Lofty
Mount Lofty 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 Mount Lofty homeowners
Does the morning fog on the escarpment hurt solar?
It trims morning output on foggy days, mostly in autumn and winter. Afternoons are usually clear, which is why we favour north and west-facing planes on Mount Lofty. Our estimate uses 20-year satellite data for the suburb, so the fog is already priced in.
My biggest roof plane faces east to the view. Should I use it?
Sometimes as part of a split. East-facing output peaks mid-morning and is about 10 percent lower over a year than north. If the north and west planes are shaded by trees, the east plane may still be the best option, and the shade model will show that.
Is my Mount Lofty home heritage listed?
We check the Toowoomba local heritage register and the overlay maps for every address before quoting. Even for a listed home, panels on the rear and side planes are routinely fine.
