Solar installation paperwork in Perth: what you should receive and why it matters

After a Perth solar installation is complete, a professional installer should hand you seven documents: Network Connection Notice (NCN) approval, an Electrical Safety Certificate, an SAA Design and Installation Certificate, panel warranty paperwork, inverter warranty paperwork, a workmanship warranty from the installer, and monitoring platform login details. Together they prove the system is grid-legal, compliant, and covered if something goes wrong.

Most homeowners get handed this pile, file it away unread, and forget it exists until they need it: selling the house, chasing a warranty claim, or troubleshooting a fault years later. Knowing what each document is for means you can chase up anything missing while the installer relationship is still fresh, not after the business has moved on.

The seven documents at a glance

---

What is the Network Connection Notice, and why does it matter?

What it is: A letter or email from Western Power confirming your solar system has been approved for grid connection at your property, with a reference number attached.

Why it matters:

• Without a lodged NCN, your system isn't technically grid-legal
• Synergy needs the NCN reference before it will register you for DEBS
• Buyers ask for it if you sell your home and want to show solar compliance
• Some insurance claims require it

Who lodges it: Your SAA-accredited installer submits the NCN before installation, and Western Power approves it. Most standard residential applications clear automatically within a day. A smaller share need manual review and can take up to 15 business days. Our guide on checking a solar installer's credentials covers how to confirm accreditation before you sign anything.

When you receive it: Either during the pre-installation process, when the installer tells you they've lodged it, or after commissioning. Some installers hand over a copy of the approval; others just confirm verbally that it's done.

If you don't have it: Ask your installer for the NCN reference number and a copy of the Western Power approval. If they're not responding, contact Western Power directly with your address to check the connection status. Our deeper walkthrough on Western Power's NCN process covers timing and what happens before your first DEBS payment.

What is an Electrical Safety Certificate, and who issues it?

What it is: A formal certificate from the licensed electrician who did the electrical work: connecting the inverter to your switchboard, DC wiring, earthing. It certifies the work meets the AS/NZS 3000 wiring rules and the solar-specific standards on top of them.

Why it matters:

• Needed for home building or contents insurance claims involving the solar system or an electrical fault
• Needed if you sell the property
• Confirms a licensed electrician did the work, not unlicensed labour
• Required for some body corporate or strata applications

Who issues it: The licensed electrician who performed the work. Often that's an employee of the installer; sometimes it's a licensed subcontractor.

When you receive it: At completion. If you paid in full on the day and didn't get one, follow up within a week rather than waiting.

Format: Paper or email PDF. In WA it's formally a Certificate of Compliance, Electrical Work.

What is the SAA Design and Installation Certificate for?

What it is: A document confirming the system was designed and installed by an SAA-accredited person, and recording the specifications: panel model, inverter model, system size, and installation address.

Why it matters:

• STCs can't be assigned without it. Your point-of-sale discount comes from STC assignment, and this certificate is part of that paperwork trail
• It confirms the installer held SAA accreditation at the time of installation
• It's a formal record of the system as actually installed, which matters if a dispute ever comes down to "what was quoted versus what was fitted"

When you receive it: Some installers hand this over without being asked. Others only produce it on request, so ask for it explicitly.

What should my panel warranty paperwork tell me?

What it is: The panel manufacturer's warranty certificate or terms, covering two separate things.

1. Product warranty, for defects in materials or workmanship. Typically 10 to 15 years, with some premium ranges running longer.
2. Performance warranty, for how much output the panels still produce over time. A common benchmark is around 90% of original output at year 10, tapering to around 80% at year 25.

Why it matters:

• If a panel fails or underperforms after its warranty period ends, you have no recourse
• The warranty sits with the manufacturer, not automatically your installer
• Panel models differ. Check that the terms in your documents match what was actually quoted

What to do with it: Note the warranty hotline or claims process, and file the paperwork with the rest of your solar documents. Also note the installation date: warranties run from that date, not the quote date. For more on how these terms play out in practice, see our full guide to solar panel warranties.

How long is my inverter actually under warranty?

What it is: The inverter manufacturer's warranty certificate or registration confirmation. There's no single industry-wide number here: depending on the brand and model, expect somewhere in the 5 to 12 year range. Fronius, Sungrow and SolarEdge are common names on Perth roofs, and each runs its own term and its own registration process, so check the paperwork for your specific inverter rather than assuming a figure.

Registering usually matters more than the sticker warranty. Many manufacturers run a shorter base term, often five years, that only extends to the full ten (or more) once you register the inverter online within a set window after installation. That registration step is separate from anything your installer does on your behalf. Look for a QR code or web address in your inverter paperwork and register it yourself, ideally in the first few weeks.

Why it matters:

• Skip registration and you could be sitting on half the warranty term you thought you had
• Registering also puts you in direct contact with the manufacturer for support, rather than routing everything back through the installer

What does the installer's workmanship warranty cover?

What it is: The installer's own warranty over the quality of the physical installation: roof penetrations, racking, cable management, connections. The New Energy Tech Consumer Code sets a minimum five-year whole-of-system warranty here, so anything shorter than that isn't compliant.

Why it matters:

• It covers labour for fixing installation defects: panel leaks, wiring failures, mounting failures
• It's distinct from the panel and inverter warranties, which cover the products themselves, not the fitting
• It's only as good as the installer's continued existence. A five-year warranty from a business that closes in year two is a warranty in name only

What to check: Does it cover labour only, or parts and labour together? Is there a call-out fee attached to a warranty claim? If you ever need to use it, our guide on making a solar warranty claim in Perth walks through the process for panels, inverters, and workmanship.

How do I confirm my monitoring platform is working?

What it is: Login credentials for your inverter's monitoring platform: Fronius Solar.web, Sungrow iSolarCloud, SolarEdge monitoring, Enphase Enlighten, and similar. Some installers set this up for you; others leave it as a task on your list.

Why it matters:

• Monitoring is the only way to know whether your system is generating what you'd expect
• It catches faults early: an underperforming string, an inverter error code
• You'll want it for an annual health check anyway

What to check: Log in and confirm you can see live data. A "no data" reading in the app usually means a communication fault between the inverter and the platform, not a generation problem, so contact your installer to check the connection rather than assuming the worst.

Where should I keep all this paperwork?

Keep everything together, either as a physical folder in the home files or a scanned folder in cloud storage. Include:

• NCN reference number and approval document
• Electrical Safety Certificate
• SAA certificate
• Panel warranty, with manufacturer contact and warranty period noted
• Inverter warranty, with registration confirmation
• Installer workmanship warranty
• A copy of the original quote or contract, for comparison if a dispute ever arises
• The installation date

For everything else worth doing in the first month after your system goes live, our 30-day post-installation checklist covers the rest.

What if my installer won't send these documents?

Most installers keep their own records. Contact them directly and ask for specific documents by name rather than "the paperwork". Allow a few business days for a reply before chasing again: there's no official standard here, it's just a reasonable window for a business to pull a file.

If the installer has stopped operating rather than just running slow, here's where to go instead:

• NCN: Contact Western Power directly with your address
• Electrical Safety Certificate: Contact your state electrical licensing authority (Electrical Safety Office WA, part of Energy Safety WA)
• SAA certificate: Contact your original installer, or verify their accreditation directly via Solar Accreditation Australia's public register
• Warranties: Contact the panel and inverter manufacturers directly using the product serial numbers on the nameplates on your roof or wall

If the business itself has folded, our guide on what to do when your solar installer goes out of business covers the specific steps for each document type.

Solar documentation is worth ten minutes of filing attention at installation time. The alternative is tracking it all down under time pressure, mid house-sale or mid warranty dispute, with an installer who may no longer be answering the phone.
