What to Check After Your Solar Installation Is Complete?

The installers have packed up, the roof is looking a little different, and you’ve got a new bit of kit sitting on the wall.

Job done, right?

Almost.

Before you put the paperwork in a drawer and get on with your day, take a little time to check that everything you paid for is there, the system has been properly handed over, and you know what happens next.

This is particularly useful for Perth homeowners because a solar installation is not finished simply because the panels are sitting on the roof. There can still be commissioning, connection, documentation or monitoring matters to sort out.

You do not need to climb onto the roof or touch electrical equipment. Most of these checks can be done from the ground, through your monitoring app and by going through the handover information with your installer.

Your Post-Installation Solar Checklist

Before you call the job finished, check that you have:

  • The equipment you agreed to purchase
  • The agreed number and general layout of panels
  • A tidy and completed installation
  • Access to your monitoring system
  • Confirmation of the system’s operating status
  • The relevant electrical and commissioning paperwork
  • Product and workmanship warranty information
  • Equipment manuals and instructions
  • A safe shutdown and isolation procedure
  • A record of any work still outstanding
  • Your solar installer’s contact details

If something does not look right, ask about it before assuming it is normal.

1. Check That the Equipment Matches Your Agreement

Start with the simplest question:

Did you receive what you bought?

Have your final quote or contract nearby and compare it with the equipment installed.

Check the:

  • Solar panel brand and model
  • Number of panels
  • Inverter brand and model
  • Battery, if included
  • Optimisers or other equipment, if included
  • Monitoring hardware or service
  • Other equipment specifically listed in your agreement

You do not need to inspect electrical connections yourself. You are simply checking that the finished system corresponds with the documents you signed.

If something has been substituted, ask the installer why and ask for the change to be documented.

2. Compare the Finished Panel Layout With Your Final Plan

Look at the roof from the ground and compare it with the final panel layout supplied for your property.

You are looking for obvious differences in:

  • Number of panels
  • Position of the arrays
  • Areas of the roof being used
  • Any panels that appear to be missing
  • Significant changes from the agreed design

Do not climb onto the roof to carry out this check.

Perth roofs can be hot, steep and awkward to access, and there is no reason for a homeowner to put themselves at risk just to inspect an installation.

If something looks different from the plan, take a photo from a safe spot and ask your installer about it.

3. Have a Good Look at the Finished Work From the Ground

You are not carrying out an electrical inspection here.

You are checking whether there are any obvious signs that the job has not been finished properly.

From a safe position, look around the installation for things such as:

  • Visible damage to equipment
  • Loose-looking or poorly finished external cabling
  • Unfinished work around the inverter
  • Damage to areas of the property caused during installation
  • Debris or materials left behind
  • Anything that looks noticeably different from what you discussed with the installer

If you have a tiled roof, pay attention to any signs of damage that become visible after the installers leave. You do not need to get onto the roof to investigate it.

If you notice a problem, photograph it and contact the installer rather than trying to fix it yourself.

4. Make Sure You Can Access Your Solar Monitoring

This is one of the easiest checks to overlook.

Your installer should explain how you can view the system through its monitoring app or online portal, where one is provided.

Before the installer leaves, make sure you know:

  • Which app or portal to use
  • Which email address is linked to the account
  • How to log in
  • Where to see your system status
  • Where to view available generation information
  • Who controls the account
  • Who to contact if monitoring stops working

If you have an Enphase, SMA or other monitored system, the exact screens will vary.

The important thing is that you can access your own system information and understand
what you are looking at.

A monitoring account that only the installer can access is worth sorting out before everyone goes their separate ways.

5. Find Out Whether Your System Is Actually Ready to Operate

This is worth asking directly.

A completed physical installation does not always mean you can immediately operate the system under its final grid connection arrangement.

Ask your installer:

“Is my system ready for normal operation now?”

Then ask:

“Is there anything still waiting on the retailer, network or another party?”

Your installer should explain what has been completed and whether anything remains.

For newer systems in WA, there are also current requirements around grid communication capability and installation capability testing. Systems installed or upgraded from 1 May 2026 in the SWIS need to meet the applicable requirements.

You do not need to understand the technical side of those requirements. You simply need to know whether the installer has completed the steps that apply to your system.

6. Get Your Handover Paperwork Together

This is the boring bit that becomes very useful a few years down the track.

Keep your solar documents together in one place, preferably somewhere you will still be able to find them if you move house, change electricity retailers or need warranty work.

Your handover file should include the documents relevant to your installation, such as:

  • Final system specifications
  • Electrical Safety Certificate
  • Commissioning information
  • Product warranty documents
  • Installation or workmanship warranty
  • Equipment manuals
  • Monitoring instructions
  • Shutdown and isolation instructions
  • Installer and retailer contact details
  • Any relevant records of outstanding work

The Australian Government recommends keeping the contract, system specifications, operating instructions, warranty information, product information, installer details and commissioning information after installation.

7. Check Your Electrical Safety Certificate

For Perth and the rest of WA, this is an important document to keep.

WA electrical contractors must provide an Electrical Safety Certificate for applicable electrical installation work within 28 days of completion. The certificate confirms that the work has been completed, checked and tested and is safe and compliant.

If you have not received yours within the required timeframe, contact the electrical contractor who carried out the work.

Put it somewhere safe once you receive it.

It is not the sort of document you want to be hunting for years later when you are trying to sort out a warranty question or sell the property.

8. Ask What Is Still Outstanding

Before the installer leaves, ask one very plain question:

“Is there anything left to do?”

There may be nothing.

But if there is, you want to know exactly what it is.

For example, ask whether anything remains relating to:

  • System commissioning
  • Connection
  • Metering
  • Monitoring
  • Paperwork
  • Inspections
  • Remedial work
  • A replacement component
  • A follow-up visit

If something is outstanding, ask for it in writing.

A quick email confirming what remains to be done can save a lot of mucking around later.

9. Learn the Safe Shutdown Procedure

You should know what to do if the system needs to be isolated during an emergency or for future electrical work.

Ask your installer to show you the relevant shutdown and isolation procedure for your system.

You should also know:

  • Where the relevant equipment is located
  • What the normal operating indicators mean
  • Who to call if a fault appears
  • What to do if the monitoring system reports a serious fault

Do not open the inverter, battery or other electrical equipment yourself.

Do not pull cables, remove covers or start testing electrical components because something looks unusual.

If you are unsure, leave it alone and contact a licensed professional.

10. Take Photos Before You Forget

Take a few useful photos of the completed installation.

You might want:

  • A photo showing the finished panel layout
  • The inverter
  • The battery, if installed
  • Equipment labels and serial numbers
  • The relevant switchboard area
  • Other visible equipment

These photos can be handy later if you need to identify a component, make a warranty claim or explain an issue to your installer.

You do not need a professional camera.

A few clear phone photos, saved with the installation date, will do the job.

11. Keep a Record of Your System's Starting Point

Once the installation has been handed over, record the basic details while they are fresh.

For example:

  • Installation date
  • System size
  • Number of panels
  • Panel make and model
  • Inverter make and model
  • Battery capacity, if applicable
  • Monitoring platform
  • Relevant serial numbers
  • Installer details

Think of this as your home’s solar record.

It gives you something to refer back to if the equipment changes, a fault develops or you need support several years from now.

12. Don't Judge the System From One Day's Production

This is an easy trap for new solar owners.

You check the app on a cloudy Perth afternoon and think:

“That’s not much. Something must be wrong.”

Not necessarily.

Solar generation varies with weather, time of day, season, shading and household conditions. A system should not be judged from one random reading.

Instead, learn what your monitoring system is showing and ask your installer what sort of operation you should expect from your particular setup.

If the system shows a persistent fault, remains offline or isn’t behaving as your installer explained, contact them.

What If Something Doesn't Look Right?

Don’t start pulling switches or trying to repair anything yourself.

Use this simple approach:

  • Something looks physically wrong: Take a photo from a safe position and contact the installer.
  • Monitoring is showing an unexplained fault: Record the message and contact the installer.
  • You have not received required paperwork: Ask the relevant contractor or installer for it.
  • You are unsure whether the system is ready: Ask the installer to confirm its operating and connection status.
  • There is a safety concern: Keep clear of the equipment and seek professional assistance.

The Australian Government also recommends putting concerns about a non-working system or property damage in writing to the company that sold the system.

What Not to Do After Your Solar Installation

You don’t need to become a solar electrician on day one.

Avoid:

  • Climbing onto the roof to inspect panels
  • Opening electrical equipment
  • Removing inverter or battery covers
  • Disconnecting cables
  • Attempting electrical repairs
  • Changing equipment settings without understanding them
  • Guessing what a fault message means
  • Assuming a problem will disappear on its own

A quick call to the installer is a much better option than turning a small concern into a safety issue.

Final Word

Once the crew has left, you don’t need to spend the afternoon crawling around the roof or staring at the inverter.

A sensible handover check is mostly about confirming what was installed, getting control of your monitoring and paperwork, understanding whether the system is ready to operate, and knowing who to call if something isn’t right.

For a Perth homeowner, that’s enough to give you confidence that the job hasn’t just been installed, but properly handed over.
