If you’ve decided to go solar — or are seriously considering it — one of the first questions you’ll ask is: How long does solar installation take?
It’s a fair question. Nobody wants to wait months without clarity, especially when power bills are rising and energy independence is calling.
The good news? For most Western Australian homes, the entire solar installation process — from first quote to switching the system on — can be completed in under four weeks. In some cases, even faster.
Let’s break down each step so you know exactly what to expect.
Solar panels thriving in the Gero sun
Step 1: Quote & System Design (1–5 Days)
Once you request quotes and choose your preferred installer, things usually move quickly.
Your provider will assess your energy usage, check your roof via satellite imaging or a site visit, and design a system tailored to your needs. This phase often takes just a few days — sometimes only one or two.
In regional WA locations like Geraldton, many solar companies are locally based and responsive, meaning shorter queues and faster communication.
Pro tip: Have a recent electricity bill ready — it speeds up the quote and system design process.
Step 2: Grid Approval (5–10 Business Days)
Before installation begins, your provider needs to apply for grid connection approval from Western Power. This is required for almost all grid-connected solar systems in WA, no matter who installs it.
The grid approval process usually takes 5 to 10 business days, though it can vary depending on your location and the current network workload.
The good news? Your installer handles this paperwork entirely — you won’t need to lift a finger.
Step 3: Installation Day (1 Day)
So, how long does a solar installation take once boots hit the roof?
For most standard residential systems (3kW to 6.6kW), the installation itself takes just one day. Installers will arrive early, set up scaffolding (if needed), install panels, connect wiring, and complete a system safety check.
Larger systems — like those with a battery or complex roof layouts — may take an extra day. But even then, the process is relatively quick and tidy.
By the end of this step, your system is physically installed and ready to go.
Step 4: Metering & Grid Connection (Up to 10 Business Days)
After installation, your electricity retailer must reconfigure your meter so your solar system can feed power back into the grid. This is the final hurdle before your system is officially switched on.
This process can take up to two weeks, depending on your retailer. Some are faster than others, and your installer may assist with follow-ups.
Once this is complete, your solar system is live — and you’ll start generating your own electricity.
So How Long Does a Solar Installation Take from Start to Finish?
Here’s a realistic breakdown for most WA homeowners:
Quote & design: 1–5 days
Grid approval: 5–10 business days
Installation: 1 day
Metering: Up to 10 business days
Estimated total time: ~3–4 weeks
In regional areas like Geraldton where solar is popular and processes are well understood, the full timeline is often shorter.
Tips to Speed Things Up
Choose a local, accredited installer – They know the WA process and work efficiently.
Get your electricity bill ready – This helps size your system and lock in a quote quickly.
Ask about metering timelines early – Some companies manage this better than others.
Be ready to approve paperwork fast – Don’t let admin delays come from your side.
Final Thoughts
So — how long does solar installation take? If you’re waiting for “the right time” to go solar, know this — the process is probably quicker than you expect. From first enquiry to generating your own clean energy, many Geraldton households are solar-powered in under a month.
The key is working with the right provider — one that knows the local process, handles the paperwork, and doesn’t leave you in the dark.
