What makes Kearneys Spring different
Kearneys Spring is a family suburb on Toowoomba's southern side, next to the university and the Kmart Plaza. The homes are mostly 1980s and 1990s brick with concrete tile roofs on flat 700 m2 blocks, with newer infill on the southern edge. It is low on trees, regular in layout and gets the full range sunshine, which makes it one of the simplest suburbs in Toowoomba to fit.
- 19,713 rooftop systems in postcode 4350, with 1,211 added in the year to July 2026

- 1,070 batteries installed across 4350 in the 12 months to July 2026
- Flat blocks and hipped tile roofs regularly fit 23 to 30 panels across two faces
- At 690 m elevation panels run cooler and closer to their rated efficiency
What postcode 4350 has already put on its roofs

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 Kearneys Spring roofs
Kearneys Spring roofs are the classic hipped tile roof with two good planes and few penetrations, and 10 kW fits on most across north and west. The 1980s tiles are ageing, so we carry replacements and check the sarking. Switchboards from this era usually accept solar without an upgrade. Hail-rated panels are standard for Toowoomba, and the cool climate keeps output high per rated watt.

What applies to a Kearneys Spring install
Council and network
Kearneys Spring has no heritage or character overlays, and the Toowoomba Regional Planning Scheme treats panels on an existing dwelling as accepted development. Energex serves the suburb with the standard 5 kW single-phase export cap and dynamic connections available for larger systems. The streets along Kearneys Spring Creek sit in the flood overlay, which affects inverter and battery height only.
STC rebate in Kearneys Spring
Kearneys Spring 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 Kearneys Spring homeowners
What size system suits a Kearneys Spring family home?
A 10 kW system for a home with ducted reverse-cycle, and 6.6 kW if you use split systems and are out during the day. New systems in 4350 averaged 11.3 kW in the year to July 2026.
Are 1980s concrete tiles a problem?
No. They carry panels easily. Age makes them brittle, so we walk carefully, use tile-replacement mounts where needed and replace anything that cracks at no charge.
How does winter solar perform in Toowoomba?
Better than most people expect. Toowoomba winters are dry and clear, and June output is typically 55 to 60 percent of January. Our month-by-month chart for Kearneys Spring shows the real curve from 20 years of satellite data.
