The Solar Installation Process: Step by Step, Day by Day

From quote to switch-on — exactly what a residential solar installation involves, how long it takes, and what to expect each stage.

A typical residential install runs from a site visit to switch-on over a few weeks (the physical installation itself is often one or two days). Here’s the realistic process so you know what to expect — and what to confirm before signing.

The steps

  1. Initial consultation and solar site assessment
  2. System design, quotes and contract
  3. Permits, approvals and grid connection application
  4. Scaffold and array installation (often 1–2 days)
  5. Electrical connection and inverter commissioning
  6. Inspection, meter/export arrangement and switch-on

How long each stage takes

  • Quoting/design: days to ~2 weeks
  • Approvals: days to several weeks (region-dependent)
  • Install: 1–2 days for typical homes
  • Connection/comissioning: days to weeks for grid meter work
How long before I can switch my system on?
Once installed by a licensed installer and approved, most systems can start operating quickly — but net-metering/meter upgrades can add weeks in some regions.
