A solar system inspection covers panel condition, wiring integrity, isolator function, inverter performance, and actual energy output, all tested against current Australian electrical standards by a licensed electrician. Systems running below optimal can lose up to 70% of their potential savings without the owner realising.
Clean Earth Solar has installed and serviced over 1,000 solar systems totalling 6.5 megawatts across Hawkesbury and greater Sydney since 2018. Our SAA-accredited electricians (the same in-house team that installs, never subcontracted) carry out every inspection. Across those systems, the most common hidden faults we identify are degraded DC isolators, water ingress in rooftop cabling, and inverter relay failures that monitoring apps miss entirely.
Below, we cover each step of a professional solar system inspection, how it differs from a solar energy audit, and when your home or business actually needs one.
A professional inspection checks your system from the switchboard to the roof, covering electrical safety, compliance with Australian standards, and real-world performance, not just how clean the panels look. Our team at Clean Earth Solar breaks this down into three stages.
This is where the inspection starts. A technician will look over the panels from ground level or with a zoom lens, checking for cracked glass, discolouration, loose frames, or obvious debris. They’ll also check the area around the array for new shading from trees or nearby buildings, since even partial shade on one panel can drag down the output of an entire string.
This is the part that actually protects you. The inspector tests the inverter for fault codes or error messages, checks isolators and ground cabling for water damage or corrosion, and confirms the system layout is displayed at the switchboard as required under AS/NZS 5033. They’ll also check that a valid Certificate of Compliance for Electrical Work exists for the installation, since this is your proof the system meets Australian wiring rules.
If the ground-level and electrical checks turn up something worth a closer look, the technician will access the roof to physically test individual panels and check mounting hardware, cabling, and connectors up close. This step is reserved for licensed professionals only. Climbing onto a roof to inspect solar panels carries real fall and electrical risks, and it’s not a job for a ladder and a Saturday afternoon.
If you’d rather have our team handle the whole process from cleaning through to fault repairs, our solar panel maintenance service covers all of this in one visit.
You need a solar site inspection any time something’s changed, whether that’s your energy bill, the weather, or who owns the property. The most common triggers we see are:
If any of these sound familiar, it’s worth booking a solar site inspection sooner rather than later. Small faults are cheap to fix. Faults that get ignored for a year rarely stay small.
A solar site inspection checklist usually covers panel condition, electrical safety, mounting integrity, and documentation, all matched against Australian wiring standards. Here’s what our technicians typically work through:
The NSW Fair Trading solar panels checklist is a useful reference if you want to see what a compliant installation should have on file, including the Certificate of Compliance every licensed installer is required to provide.
A solar inspection checks whether your existing system is safe and working properly, while a solar energy audit looks at the bigger picture, your energy usage, your bill history, and whether your current system still matches your household or business needs.
Think of the inspection as a health check for the equipment you already have, and the audit as a broader review of whether that equipment is still the right fit.
A solar energy audit typically includes a review of past electricity bills, an analysis of your usage patterns across the day and across seasons, and a comparison between what your system is producing and what it was designed to produce.
For homeowners, this often reveals whether it’s time to add a battery, upgrade an ageing inverter, or simply confirm the system is still earning its keep.
Commercial solar energy audits go further than residential checks because businesses have higher stakes, tighter compliance obligations, and systems that are often far larger and more complex. For a commercial site, our team reviews peak demand data, load profiles, and metering alongside the physical condition of the array.
A typical commercial solar energy audit includes:
If your business is due for a review, our commercial solar team can run a full solar site assessment and walk you through the findings in plain English, not jargon.
Most solar systems in Australia should have a solar site assessment at least once a year, though your actual frequency depends on system age, roof exposure, and how the system has been performing. Systems installed more than five years ago, or systems that sit under trees or near the coast, often benefit from more frequent checks.
It’s also worth knowing that the Clean Energy Regulator runs a national inspections program that covers a sample of small-scale solar installations across Australia each year.
As the Clean Energy Regulator explains, these inspections give homeowners assurance that their system was installed correctly and help maintain standards across the industry, though they’re not something you can request for your own peace of mind, so a private solar site assessment is still the way to go if you have concerns.
There’s a bit you can safely check from the ground before booking a solar system inspection. Look at your inverter display for error messages or a blank screen. Check your monitoring app for a sudden drop in daily output. Walk the yard and see if any new trees or structures are casting shade on the array that wasn’t there before. Keep an eye out for bird nesting, since droppings and nesting material under panels can cause hidden damage over time.
What you shouldn’t do is get on the roof yourself. Anything involving panel access, wiring, or isolators is a job for a licensed electrician, both for your own safety and because DIY work on the array can void your warranty.
A solar system inspection isn’t just a box-ticking exercise. It’s what stands between a system quietly losing you money and one that keeps performing the way it was designed to for the next twenty years. Whether you need a straightforward residential check or a full commercial solar energy audit, Clean Earth Solar’s SAA-certified team has been servicing systems across Hawkesbury and greater Sydney since 2018, backed by a lifetime workmanship warranty on every installation we handle.
A certified installer who has completed Sigenergy’s highest-tier training and demonstrated hands-on experience commissioning SigenStor battery, inverter, and EV charging systems.
Installation is typically bundled into the total system price rather than quoted separately. Request an itemised quote to see the labour and commissioning breakdown.
No. Sigenergy battery costs are comparable to Tesla Powerwall 3 and Sungrow, and the all-in-one design eliminates the need for a separate inverter or EV charger.
Yes. Both the Sigenergy AC and DC EV chargers can be retrofitted to existing solar systems, subject to a switchboard and site assessment.
The AC charger suits affordable overnight charging. The DC charger charges faster and supports Vehicle-to-Home (V2H) and Vehicle-to-Grid (V2G) energy sharing.
Yes. Sigenergy batteries are eligible for Australia’s Cheaper Home Batteries Program when installed by an accredited installer using approved products.
Most residential SigenStor installations are completed in one day. Retrofits to existing solar may take longer depending on switchboard upgrades required.
Yes. Sigenergy Gold Installer status requires manufacturer-specific training on SigenStor commissioning and the mySigen app, beyond standard CEC accreditation.
