About QSX

We got tired of solar quotes that hid the numbers

QSX Energy was founded by engineers and electricians who kept being called out to fix undersized, oversold systems. So we built the opposite.

Our story

Estimate first, sales conversation second

Most solar companies start with a phone call and end with a number. We start with the number. The Smart Estimate exists so you can decide whether solar stacks up for you before speaking to anybody — and so our team only spends time on jobs that genuinely make sense.

Everything after that is unglamorous discipline: correct sizing, quality components, clean workmanship, and being reachable in year six when something needs attention.

  • CEC accredited designers and installers on every job
  • In-house install crews — no anonymous subcontractors
  • Clean Energy Council approved product list only
  • Transparent modelling shared with every proposal
  • Local supplier relationships for fast warranty claims
  • Post-install monitoring and annual performance review

What we value

Three rules we don't bend

Size it right

A system that is too big is as wasteful as one that is too small. We recommend the size the data supports.

Show the working

Production, self-consumption, feed-in and payback assumptions are all shared, not summarised into one hero number.

Stay reachable

The same team that installed your system answers the phone when you call about it.

Ready when you are

See your savings in about 60 seconds

Our Smart Estimate tool designs a system on your actual roof and shows the numbers before you talk to anyone.
