Solar Repaired Properly, So It Earns Its Keep Again
A solar system that’s dropped in output is costing you money every day it’s left alone. Every kilowatt you’re not generating is power you buy back from the grid at full retail rates, and every bit of export you’re missing is credit that should be landing on your bill. Left long enough, a quiet fault can wipe out most of the savings the system was bought to deliver.
We diagnose the actual fault, inverter errors, isolation faults, a string that’s stopped producing, or panels underperforming, and fix it at the source. Not a guess, not a part swapped on a hunch, and not a push to rip the whole system out when one component is the real problem.
Because we’re licensed electricians as well as CEC-accredited solar technicians, we follow the fault through the whole system, panels, inverter, wiring and switchboard. A lot of solar-only operators stop at the inverter, because the switchboard and wiring side isn’t their trade. It’s ours, and that’s often exactly where the fault is hiding.
Why Adelaide Solar Systems Lose Output Over Time
Adelaide gives solar a hard life. Long, hot summers mean panels and inverters run at high temperatures for months on end, and heat is what wears electronics out. Add years of dust, the odd storm, and the simple fact that a lot of older systems were never sized for how much power a modern home uses, and a gradual drop in output is almost expected.
Most of the faults we see fall into a handful of buckets:
- Inverter faults, the inverter is the hardest-working part of the system and usually the first to fail or start throwing error codes.
- Isolation and earth faults, often traced back to DC isolators, a known weak point on a lot of South Australian installs.
- Dead or underperforming strings, one failed panel or connection can drag down everything wired with it.
- Monitoring dropouts, when the app stops reporting, a system can sit half-dead for months before anyone notices.
The tricky part is that none of this usually announces itself. The system still switches on, the panels still sit on the roof, and the only real clue is a power bill creeping back up. That’s why a proper diagnosis matters more than a quick look.
What Our Solar Repairs Cover
We repair the whole system, not just the easy-to-reach parts:
- Inverter fault diagnosis and error code troubleshooting
- “Inverter isolation” and earth fault investigation
- Underperforming or dead panel strings
- Isolator and switchgear faults
- Wiring, connection and switchboard issues
- System performance and output testing
- Monitoring and app reconnection
If a repair turns into a bigger conversation, say the inverter really is beyond it, we’ll walk you through replacement options honestly, including whether it’s worth doing now or holding off.
A Repair-First Approach Saves You Money
Plenty of faults that look like “your system’s had it” are a single failed component. We tell you straight which one it is, rather than using a fault as an excuse to sell you a whole new system.
Repairing the right part means:
- You keep the system you already paid for
- You’re back to full output sooner
- You’re not sold a full replacement you didn’t need
If a system genuinely is beyond economical repair, we’ll tell you that too, and explain why in plain terms, with the numbers to back it up. Sometimes the honest answer is that a repair buys you a few more good years cheaply; sometimes it’s that you’d be throwing good money after bad. Either way, you get the full picture before you spend anything.
What to Expect When We Inspect Your Solar
An inspection with us is a diagnosis, not a sales pitch. Here’s how it runs:
- We test the system end to end and pull the inverter’s error history, rather than guessing from a single fault light.
- We measure what each string is actually producing and compare it to what it should be.
- We check the isolators, wiring and switchboard, the electrical side a solar-only crew often skips.
- We reconnect and check your monitoring so you can see the system working again.
- We explain what’s wrong, what it’ll take to fix and what it’ll cost, before any work goes ahead.
You’ll come away knowing exactly what’s going on with your system, even if the answer is that nothing urgent needs doing.
Signs Your Solar Needs Attention
- Power bills creeping back up despite having solar
- Inverter showing a fault light or error code
- Monitoring app showing low or zero output
- System tripping or shutting down
- An older system that’s never been checked
- Output that’s quietly dropped off over time
If any of these sound familiar, an inspection is the sensible next step, the longer a fault runs, the more it quietly costs you in power you’ve already paid to generate.
What Affects the Cost of a Solar Repair
We can’t put a flat price on a repair before we know what’s wrong, because the fault has to be found first. What we can do is be upfront about what drives the cost:
- Whether the fault is a single part (like an isolator) or a major component (like the inverter)
- How accessible the fault is, roof, switchboard or somewhere in between
- Whether parts are still available for your brand and age of system
- Any safety or compliance work that needs doing at the same time
We quote after the diagnosis, explain the findings clearly, and only proceed once you’ve said yes. Flexible payment options are available through Brighte if you’d rather spread the cost.
Our Approach to Solar Repairs
We treat a repair as a diagnosis, not a sales call.
- Test the system properly and find the real fault
- Explain what’s wrong and what it’ll take to fix
- Repair at the source so it doesn’t come back
- Recommend further work only when it’s genuinely needed
You’ll know exactly what’s wrong with your system and what, if anything, needs doing. And because the work is done by our own technicians, employed, not subcontracted, the person on your roof is accountable for the job, backed by our lifetime workmanship warranty.
Frequently Asked Questions
Why has my solar stopped producing power?
The most common causes are inverter faults, an isolation or earth fault, or a failed panel string. A proper diagnosis identifies which one rather than guessing, so the right part gets fixed the first time.
Do you repair systems you didn't install?
Yes. We repair a wide range of residential solar systems across Adelaide, regardless of who installed them or which brand they are.
Can you fix an inverter, or does it need replacing?
It depends on the fault. Some inverter issues are repairable; others are more economical to replace. We diagnose it first and give you the honest answer before any work goes ahead.
How much does a solar repair cost?
Repairs are quoted after diagnosis, because the fault has to be found before anyone can price the fix. We explain our findings and the cost clearly before proceeding.
How long does a solar repair take?
Many repairs are sorted in a single visit once the fault is diagnosed. If a part has to be ordered in, an inverter or a brand-specific component, it can take longer, and we’ll give you the timeframe up front.
Will I lose power during the repair?
Your home stays connected to the grid throughout, so your lights and power keep working. We may need to shut the solar system down safely while we work on it, then bring it back online once the repair is done.
Do you warranty your repairs?
Yes. Our workmanship is backed by our lifetime workmanship warranty, and any parts we supply carry their manufacturer’s warranty.
Is my solar still safe to use with a fault?
Some faults are a safety concern, particularly isolation and wiring faults. If your system is showing an error or behaving oddly, it’s worth having it checked rather than leaving it running.
How often should I have my solar checked?
A health check every few years is sensible, especially for older systems or any that have never been looked at. If yours is showing any of the warning signs, sooner is better.
Are you qualified to work on solar?
Yes. We’re CEC accredited for solar work and fully licensed electricians, so the whole system is covered, from the panels through to your switchboard.
