Solar panel installation,
across South East Queensland.

A residential solar system in SEQ now typically pays itself back in three to five years — faster if you size it for a future battery. We design, install and commission systems from 6.6 kW up to 30 kW.

001 The maths in 2026

Stop buying power. Not sell it back.

Feed-in tariffs have dropped. The Energex network no longer mandates a minimum, and most retailer plans now pay 5–8 c/kWh for exports. But import rates are 30 c+/kWh in the evening peak.

The financial story is no longer "sell power back" — it's stop buying power. Every kWh you generate and use yourself is worth roughly four to five times what you'd get exporting it.

That makes sizing more important than it used to be. Oversize the array for a battery you'll add later, and you front-load the value.

002 What we install

Components, named.

We're brand-agnostic. The recommendation matches your roof, not our warehouse.

003 Sizing

What size is right for your home.

Savings depend on usage pattern, retailer plan and feed-in rate. Final figures land on your bills, not in the brochure.

HouseholdRecommended sizeTypical annual savings
1–2 people, low usage6.6 kW$1,400 – $1,800
3–4 people, average usage10 kW$2,200 – $2,800

Large family or home office15 – 20 kW$3,500 – $5,000

004 Federal STC rebate

Applied at the quote, not at a form.

When we install your system, it generates Small-scale Technology Certificates under the SRES. We assign those certificates back to you as a point-of-sale discount. On a 6.6 kW system in 2026, that's roughly $1,600 off. The discount is on your quote. There's no claim form, no waiting period.
