Monitoring
See exactly what your system is doing
Every install ships with panel-level monitoring so you can watch production, self-consumption and battery state from your phone.
Why QSX
Built for households that want the maths to hold up
Every proposal shows production, self-consumption, feed-in value and payback — the same numbers we would want if it were our roof.
Honest modelling
Estimates use your address, roof orientation, shading and tariff — not a national average.
Warranty that means it
CEC approved products with local supplier support and a QSX workmanship warranty.
Clean installs
Tidy cable runs, correctly rated isolators and full compliance documentation.
Rebates handled
STCs, state battery incentives and grid applications are lodged by us on your behalf.
Customers
What people say after the first bill
A few hundred systems across QLD, NSW and VIC — here's the feedback that keeps showing up.
The estimate matched the final quote almost exactly. That never happens with solar.
They talked us out of a bigger system than we needed. Bill went from $640 to $70 a quarter.
Battery paid for the summer already. Install crew left the site cleaner than they found it.
FAQ
The questions we get every week

If your evening usage is high or you want blackout backup, now. If not, we design the solar system to be battery-ready so adding one later is straightforward.
Most residential systems are installed in a single day. Grid connection approval and meter reconfiguration usually take a couple of weeks.
Yes. STC assignment and applicable state incentives are applied to your price up front and lodged by our team.
