Wellington Point Solar & Battery: A Bayside Guide to Energy Independence
Wellington Point homes sit close enough to Moreton Bay that salt exposure is a genuine consideration, and close enough to the water that afternoon sea breezes keep panel temperatures down. The second point is rarely mentioned and works in your favour — solar panels lose efficiency as they heat up, so a bayside roof often outperforms an identical array further inland.
Here is what a recent Wellington Point installation delivered.
The system
- Solar array: 6.65kW
- Battery: 18.1kWh of storage
- Annual generation: 9,778 kWh
- Energy self-sufficiency: 100%
This is a modest array paired with a substantial battery, and that ratio is deliberate. The household did not need a huge roof array. They needed to stop buying power at Energex peak rates in the evening.
Seasonal generation
| Season | Average daily generation |
|---|---|
| Summer (Dec–Feb) | 34 kWh/day |
| Autumn (Mar–May) | 24 kWh/day |
| Winter (Jun–Aug) | 20 kWh/day |
| Spring (Sep–Nov) | 30 kWh/day |
Even in June, the lowest month of the year, the array averages 16 kWh a day. Paired with 18.1kWh of storage, that is enough to cover a typical household’s daily use through winter.
The numbers
| Measure | Figure |
|---|---|
| Annual generation | 9,778 kWh |
| Self-sufficiency | 100% |
| Rebates applied | $5,872+ |
| Estimated lifetime savings (20 years) | $33,141+ |
| Payback period | Under 11 years |
What to expect: the installation process
1. Site assessment and design
We look at roof orientation, shading, switchboard condition and your actual consumption data — not a guess based on household size. Bayside properties also get a check on mounting hardware, since standard rail is not always appropriate near salt air.
2. Quote and approvals
You get a written proposal with the equipment specified by make and model. We handle the Energex connection application.
3. Installation day
Most systems this size go in within a single day. On this Wellington Point job the crew completed the full install in one day, with particular attention to clean cable runs.
4. Commissioning and handover
The system is tested, the monitoring app is set up on your phone, and someone walks you through it before leaving.
What the homeowner said
Paul had obtained three quotes before choosing Connect Energy. In his five-star review he noted that our consultant explained his options more clearly than the other two companies, that the quote turned out to be the most reasonable of the three, and that the crew arrived promptly and took time to explain the monitoring app before leaving.
Coastal considerations worth knowing
Within a few kilometres of the bay, three things matter more than they do inland:
- Mounting hardware. Anodised aluminium and stainless fixings resist salt corrosion. Cheaper hardware does not.
- Inverter placement. Position it out of direct salt spray and away from prevailing onshore wind where possible.
- Panel cleaning. Salt film builds up faster near the water. An occasional rinse restores output.
