What makes Wynnum different
Wynnum sits on Moreton Bay 15 km east of the CBD, a suburb of post-war weatherboard, 1970s brick and a growing number of bayside rebuilds. It is flat, open to the sky and gets a sea breeze every afternoon. That salt breeze is the one design factor that matters here: every fastener and rail on a Wynnum roof needs to be specified for a marine environment.
- 5,811 systems installed in postcode 4178, with 448 added in the year to July 2026
- 421 batteries installed across 4178 in the 12 months to July 2026
- Flat, open bayside blocks with little shading deliver the full 5.1 sun-hours
- Marine-grade rails and stainless fasteners are standard within 1 km of the bay
- Wynnum is 45 km from our Ormeau depot via the Gateway, a routine same-week run
What postcode 4178 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 4178, which covers Wynnum.
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 Wynnum home: Bayside family home with split-system air. Adjust to match yours.
Sea breezes cut summer cooling loads compared with inland Brisbane, so bills are a little lower and 6.6 kW covers most bayside homes. Larger families with pools go to 10 kW.

What we find on Wynnum roofs
Wynnum is within 1 km of the bay for most of the suburb, which puts it in a high corrosion category. We use marine-grade anodised aluminium rail, stainless steel fasteners and panels rated for salt mist. The flat blocks and open sky mean minimal shading and very consistent generation. Older tin roofs are common and quick to fit; the 1970s tile roofs take a little longer but hold a 10 kW array easily.
- Housing era
- 1940s to 1970s homes, 2000s to 2020s bayside rebuilds
- Roof material
- Tin on the older homes, concrete tile on 1970s brick, Colorbond on rebuilds
- Roof pitch
- Moderate, 15 to 25 degrees
- Typical block
- Flat, 500 to 700 m2
- Home type
- Detached family homes, some duplexes
- Shading
- Low, open bayside blocks
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 |
| 13 kW | 30 | about 60 m² |
Bayside family home with split-system air: 6.6 kW, self-consumption around 35%.
What applies to a Wynnum install
Council and network
Wynnum has small pockets of the Traditional building character overlay around the older streets but no broad heritage constraints. The coastal hazard overlay affects the lowest blocks near the Esplanade, where we mount inverters above the storm tide level. Energex serves the suburb, with the standard 5 kW single-phase export limit. Panels on existing homes need no council application. We specify a corrosion category C4 or higher mounting system on every Wynnum job as standard.
STC rebate in Wynnum
Wynnum 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 4178 added 421 batteries in the year to July 2026. We size the battery to your evening use, not the biggest unit on the truck.
Asked by Wynnum homeowners
Does salt air damage solar panels in Wynnum?
It damages cheap mounting hardware, not quality panels. We use marine-grade rail, stainless fasteners and panels certified to IEC 61701 salt mist testing. Our 30-year workmanship warranty covers the install in full.
Do I need to clean panels more often near the bay?
Salt film builds up a little faster, but Brisbane's summer storms rinse it off. A hose-down once or twice a year from the ground is usually enough. We do not recommend walking on a wet tin roof to clean panels.
What system size suits a Wynnum home?
A 6.6 kW system covers most three-bedroom homes with split-system air. Homes with a pool or ducted air are better at 10 kW. New systems in 4178 averaged 10.4 kW in the year to July 2026.
Suburbs we cover near Wynnum
