What makes Newtown different
Newtown is an inner-western suburb of Toowoomba, a grid of 1920s to 1950s weatherboard and fibro cottages on 500 to 700 m2 blocks around Newtown Park. It is flat, close to the city and increasingly popular with first-home buyers and renovators. The roofs are simple tin gables and hips, and the main variable is the age of the electrical switchboard.
- 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
- Tin cottage roofs make a 6.6 kW install a half-day job with no tile breakage
- Flat inner-city blocks with light shading deliver the full 5.5 sun-hours a day
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 Newtown, along with Centenary Heights, East Toowoomba, Glenvale, Kearneys Spring, Mount Lofty 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 Newtown home: Renovated cottage, split-system heating, young couple. Adjust to match yours.
Younger households out during the day keep self-consumption near 30 percent, which is why the 6.6 kW system is usually paired with a battery here rather than upsized.

What we find on Newtown roofs
Newtown cottages have simple tin roofs with a clear north or west plane that takes 6.6 kW quickly, and tin means no tile breakage and a half-day install. The switchboard is the thing to check: many cottages still have ceramic fuses, and Energex requires safety switches and a modern board before solar connects. We inspect and quote the upgrade up front. Renovated homes usually already have it done.

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 |

Renovated cottage, split-system heating, young couple: 6.6 kW, self-consumption around 30%.
What applies to a Newtown install
Council and network
Newtown has pockets of the character overlay under the Toowoomba Regional Planning Scheme, but panels on an existing dwelling are accepted development throughout. Energex serves the suburb with the standard 5 kW single-phase export cap. Ceramic fuse boards must be upgraded to circuit breakers and safety switches before connection. Units near the Showgrounds sit on shared title and need body corporate consent.
STC rebate in Newtown
Newtown 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 Newtown homeowners
My Newtown cottage has an old fuse box. What does that mean for solar?
The board must be upgraded to circuit breakers and safety switches before Energex will connect solar. It typically costs $800 to $1,500 depending on the board, and we include it in the quote. The house is safer for it either way.
What is the cheapest worthwhile system for a small cottage?
A 6.6 kW system is the sweet spot: the STC rebate covers a large share of the cost and the roof usually fits it on one plane. Going smaller saves little because the fixed costs stay the same.
Is a battery worth it if we are out all day?
Often, yes. Without a battery most of your daytime solar exports at 6 cents while you buy power in the evening at 32 cents. A 10 kWh battery with the federal discount changes that equation for a household on this pattern.
