Solar in Modbury — What You Need to Know
Modbury is Adelaide's northeastern suburban centre — a 1960s–1980s development hub in the Tea Tree Gully area where standard brick veneer housing on suburban lots and a relaxed planning environment create conditions that are solar-straightforward. The City of Tea Tree Gully covers the Modbury area, and the council has been proactively supportive of renewable energy — Tea Tree Gully was an early participant in SA's community solar programs. Heritage overlays are minimal for Modbury's post-war residential stock, and the installation environment is uncomplicated..
Modbury's position on Adelaide's northeastern fringe (Adelaide Hills slope country at 80–120m elevation) gives it interesting solar characteristics. The suburb sits above the Adelaide metropolitan fog layer that occasionally affects lower coastal and plains suburbs in winter — mornings here are clearer than the coastal suburbs, and the elevation gives marginally better annual radiation than the flat plains. Bureau of Meteorology data for the Tea Tree Gully area shows approximately 5.0 peak sun hours daily — among Adelaide's better performing postcodes. The Adelaide Hills foothills proximity means some properties on the hills-facing eastern side of Modbury have afternoon shading from the escarpment but this is a minority of properties..
Modbury has one specific solar consideration: the suburb's high proportion of split-level and two-storey homes on the undulating Tea Tree Gully terrain. Split-level homes often have roof planes facing in multiple directions at different heights — a configuration that benefits from microinverter or DC optimiser technology to extract maximum value from each independent roof plane. The northeast-facing slopes (common on Modbury's hills-facing properties) generate strong morning output; northwest-facing slopes capture afternoon sun. An installer experienced with complex multi-level homes will model each plane independently and recommend the optimal configuration..

Modbury homes suit 6.6kW–10kW. Split-level and two-storey properties: ask your installer to model each roof plane independently before recommending a system size. Given SA's 36c/kWh rate, sizing toward 10kW is justified for medium-to-high consumption households — the electricity rate premium makes every additional kW of generation more valuable than in other states..

Solar rebates in Modbury (5092)
Modbury sits in STC Zone 3, which sets the federal Small-scale Technology Certificate discount: roughly $1,817 off a 6.6kW system in 2026, taken off the quote by your installer rather than claimed afterwards. Bigger systems earn more certificates — a 10kW array attracts about $2,753.
On top of that, South Australia offers the country's highest electricity prices — which is what makes SA paybacks the shortest. South Australia's state battery scheme closed in 2024 and 2026-27 default tariffs rose another 1.4%, so solar here runs on the federal STC and battery discounts alone — and still pays back faster than any other state because the power it displaces costs around 40c/kWh.
- Federal STC discount: ~$1,817 on 6.6kW, applied at point of sale
- Federal Cheaper Home Batteries discount: $252 per usable kWh — about $2,516 off a 10kWh battery
- State support: the country's highest electricity prices — which is what makes SA paybacks the shortest

What size solar system for a Modbury home?
With 5.0 peak sun hours a day and Adelaide electricity at around 40c/kWh, each kilowatt of panels in Modbury generates roughly 1423 kWh a year. A 6.6kW system suits most three-to-four person households; go to 10kW if you have an EV, a pool pump or a battery on the horizon, and the roof to fit 25 panels.
| System | Cost after STCs | Yearly saving | Simple payback |
|---|---|---|---|
| 5kW | $3,780–$5,540 | $1,140–$1,580 | 4.1 yrs |
| 6.6kW | $4,620–$6,720 | $1,510–$2,090 | 3.8 yrs |
| 10kW | $6,720–$9,740 | $2,280–$3,170 | 3.6 yrs |
The payback range runs from the suburb's best-case saving to a conservative estimate that assumes you use about a third of what you generate during the day and export the rest at the 3.0c feed-in rate. Self-consume more — run the dishwasher, pool pump and hot water in daylight — and the numbers improve.
Is solar worth it in Modbury?
Yes — Modbury earns a solid grade (None/100) on our scorecard, which makes a reasonable case. A typical 6.6kW install costs $4,620–$6,720 after rebates and saves about $1,510 a year, so it pays for itself in around 3.8 years depending on how much you use during the day, and then delivers 15–20 more years of near-free daytime power.
Coastal note: within a kilometre of salt water, ask for marine-grade (C5 or "coastal") rated mounting and panels with a salt-mist certification. It adds little to the price and protects the 25-year warranty.
Finding a solar installer in Modbury
Look for Clean Energy Council accreditation (the installer, not just the sales company), a local track record in Adelaide, and a quote that itemises panels, inverter, mounting and the STC discount separately. Ask what happens to your warranty if the retailer closes — panel and inverter manufacturer warranties are the ones that last.
