Does this sound familiar?

Solar problems Perth homeowners and businesses call us about.

If your system isn't working the way it should — or you're not sure if it is — we'll find out why.

Your inverter is showing a fault code or red light

An inverter fault usually means the system has stopped generating entirely. We diagnose the error code, identify whether it's the inverter, isolator, or panel string, and carry out the repair.

Find out what's wrong

Your panels aren't producing as much as they used to

Generation drops over time due to soiling, shading from new growth, panel degradation, or string faults. We'll run a performance audit against your system's expected output and pinpoint the cause.

Book a performance audit

Your power bills haven't dropped since solar was installed

This usually means the system isn't exporting, the monitoring isn't set up correctly, or you're on the wrong feed-in tariff. We'll diagnose the setup and get it working as it should.

Get it sorted

Your solar circuit keeps tripping, or the isolator feels hot

A tripping circuit usually points to a fault upstream, while a hot isolator is a sign of a degraded connection. Both can be a fire risk and need attention, not monitoring.

Get it checked

Your system is 5+ years old and has never been inspected

Most solar systems are installed and forgotten. A full system audit at the 5-year mark catches degraded panels, isolator wear, loose connections and inverter issues before they become failures.

A storm or hail has cracked or shifted your panels

Impact damage to panels doesn't always show up as an obvious break — micro-cracks can slash output without being visible from the ground. We inspect and report for insurance and repair purposes.

Scope of work

What AVL does — and doesn't do — with solar.

This is worth reading before you call. It'll save you time and make sure we're the right fit for your job.

We do
  • Diagnose faults on any brand of inverter or panel system
  • Repair and replace inverters, DC isolators, AC isolators and wiring faults
  • Solar system audits and performance reviews
  • Monitoring system setup and troubleshooting
  • Cracked panel inspection and reporting (including for insurance)
  • Pre-purchase solar audits with written report
  • Commercial and residential systems — any size
We don't
  • Install new solar systems — panels plus inverter from scratch
  • Replace entire systems end-to-end
Why the limitation? Lyell works alone. Full solar installations require a team on the roof working safely, and keeping that cost-competitive as a one-man operation isn't something he's prepared to compromise on. What he does offer is 15+ years of solar experience applied specifically to making existing systems work properly — commercial and residential, any brand.

How It Works

From first call to fault resolved — here's what to expect.

No guessing, no unnecessary parts. clear process from the moment you get in touch.

1

Tell us what's happening

Call or send a message with what the system is doing — fault codes, error lights, output figures, anything you have. The more detail, the faster the diagnosis.

We aim to respond within a few hours
2

On-site diagnosis

Lyell attends, inspects the inverter, isolators, wiring and panels, and identifies the root cause. You get a clear explanation and a fixed-price quote before any work begins.

Repair, replace, confirm

The fault is fixed, the system is verified against expected output, and you get documentation of the work. No unresolved issues, no guessing whether it worked.

Common Questions

Your questions, answered honestly.

No spin, no jargon. If your question isn't covered here, send us a message

Call 0418 780 007
My inverter is showing a fault code. Do I need a new inverter?

Not necessarily. Many fault codes are caused by isolator failures, loose connections, or grid voltage issues — not the inverter itself. We diagnose first and only recommend replacement when the inverter is genuinely at fault. Replacing parts you don't need is not something we do.

Do you work on all inverter brands?

Yes. We work on SolaX, Fronius, SMA, Goodwe, Growatt, Sungrow, Delta, Enphase, ABB and others. If you have an older or less common brand, call us — we'll let you know if it's something we've encountered and whether parts are still available.

Can you install a new solar system if I want to upgrade?

No. We only work on existing systems — diagnosis, repair, component replacement and audits. We don't do new installations. If that's what you need, we'll tell you upfront so you can find the right contractor.

How long does a solar fault diagnosis take?

Most on-site diagnostics take 1–2 hours. Simple faults like an isolator failure can often be repaired in the same visit. More complex issues — such as a failed inverter requiring a replacement unit — may need a second visit once parts are sourced.

Do you do after-hours or weekend callouts?

We'll be upfront: we don't run a 24/7 line. If something's urgent after hours, call anyway — we'll talk you through making it safe and aim to be there first thing the next business day, which usually saves you the premium an after-hours callout adds. Established customers get priority access when something genuinely can't wait.

What areas do you service?

We primarily service Perth's northern and eastern suburbs, including Ballajura, Malaga, Morley, Dianella, Beechboro, Bassendean, Bayswater, Ellenbrook, Midland and surrounding areas. Not sure if we cover your area? Just ask. We regularly travel beyond our core service area and may still be able to help.

What does your warranty cover — and can I supply my own parts?

When we supply the parts (which we recommend), you're covered twice over: the manufacturer's warranty on the product and our 3-year workmanship warranty on the installation, at no cost to you, whichever runs longer. You're welcome to supply your own materials, but then we can only guarantee our workmanship — not the product — and a faulty supplied part is the most common reason for a return visit, which is billable to diagnose. It's why we prefer to fit quality gear we know and stand behind, so if anything ever goes wrong, it's ours to sort out, not yours.

My solar circuit keeps tripping, or the isolator feels hot. Is that serious?

Do you service commercial solar systems?

Yes. Lyell has been working on commercial solar since 2011 and is comfortable with larger systems and more complex configurations. If you have a commercial system that's underperforming or has a fault, get in touch with the details.
