What to Expect on Solar Install Day in South East Queensland

Most residential solar installs in South East Queensland take one to two days. The actual day is less dramatic than people expect — most of the heavy lifting was already done in the weeks before (design, DNSP approval, panel and inverter delivery). On the day itself, the crew shows up, the panels go up, the system gets commissioned, and by knock-off you’re generating.

This post walks through exactly what happens, in order, so there are no surprises.

Before the install day

A week or so before, you’ll get a confirmation from us with the install date, the crew arrival window (usually 7:30–8:30am), and a checklist of anything we need from you. Most often that’s:

• Clear access to the meter box — we need to isolate the supply.
• Clear path to the roof access point — we’ll be moving panels and racking through the garage or side gate, so move bikes, cars and bins.
• Someone home for the day — for the safety isolation and the switch-on handover. If you can’t be home, we can arrange access through an agent, but the handover happens better in person.

Morning: setup and safety

The crew arrives at the agreed window. First task is a tailgate safety brief — the lead installer walks the rest of the team through the job, identifies fall hazards, confirms the layout against the signed design drawing. Anchor points go up on the roof for harness attachment before anyone steps onto the slope.

Then your supply gets isolated at the meter box. This means no power to the house for the install window — anywhere from a few hours to most of the day depending on system size. Plan accordingly (freezer doors stay closed; medical equipment needs an alternative arrangement if you have one).

Mid-morning to lunch: racking and panels

The mounting rail system goes up first. For a tile roof, this means lifting tiles to find the rafters, fitting tile hooks, and bedding the rails on the hooks. For a tin roof, it’s drilling and sealing each foot — slower per fixing, but cleaner.

Once the rails are in, panels go on. A 19-panel install is typically all panels mounted and clamped by mid-afternoon, depending on roof complexity. We work in pairs on the roof; one electrician runs the DC cabling back to the inverter location while the panels go up.

Afternoon: inverter, wiring, grid connection

The inverter usually mounts in the garage or on a shaded external wall. Goodwe, Sungrow and Sigenergy units all wall-mount cleanly; we’ll have confirmed the location during your design site visit.

The DC string comes down from the roof, into the inverter; AC goes from the inverter through a dedicated isolator to your switchboard. A new dedicated PV circuit breaker gets fitted in the switchboard. This is where the bulk of the certified electrical work happens — two licensed electricians on site for every install.

Late afternoon: commissioning and switch-on

Once everything’s wired, we commission the system. This means:

• Energising the array in the right sequence (DC first, then AC).
• Checking voltage and polarity at every junction — string voltage at the inverter, AC voltage at the meter.
• Verifying inverter handshake with the grid. Modern inverters have an automatic grid-connection routine that takes a few minutes on first power-up.
• Confirming generation — once the inverter is live, we should see real power output to the grid within minutes (assuming daylight, which in SEQ at install time it almost always is).

Then we switch your power back on at the meter, and the install is done.

Handover paperwork

Before we leave, the senior installer walks you through the monitoring portal on your phone — you’ll see live generation, daily production, and per-string telemetry from day one. We also hand over:

• Certificate of Electrical Compliance (CEC cert) — the electrician’s safety sign-off. This is the document that triggers your STC and CHBP rebate eligibility.
• Manufacturer warranty paperwork — panels, inverter, and (if applicable) battery.
• STC assignment form — already signed; we handle the rebate claim from here.
• Final invoice and tax invoice — depending on your payment arrangement.

After install day

For a couple of weeks after install, your meter needs to be reconfigured by Energex or Ergon to register export. This usually happens automatically once the DNSP receives our installation notification; sometimes it requires a meter swap. You’ll see the change in your next bill cycle.

Our team monitors your system from day one. If a string under- performs or a panel faults out, we open a service ticket on your behalf — you don’t have to chase us. The senior designer who built your system stays on your account.
