A Solar System That Actually Performs Again
Early solar systems were built for a different era, big feed-in tariffs, smaller household demand, and none of the battery or EV loads we plan for today. Many Adelaide homes are now running undersized, ageing systems that no longer match how the house actually uses power, quietly handing money back to the grid every evening.
When a system is past its useful life or beyond economical repair, replacing it properly restores output and sets the home up for a battery and an EV charger down the track. Done right, a replacement isn’t just a like-for-like swap, it’s a chance to size the system around the home you have now, not the one you had a decade ago.
We’re CEC-accredited installers and licensed electricians. That means the panels, the inverter, the wiring and the switchboard are all handled by the one accountable team, not a solar crew who leave the electrical side to someone else.
Why Older Adelaide Solar Systems Get Left Behind
A solar system doesn’t usually fail all at once. It slips. Panels lose a little output every year, inverters wear out faster than the panels they’re wired to, and the generous feed-in tariffs that made small early systems worthwhile have largely gone. Meanwhile the house has added more appliances, maybe a pool, maybe an EV on the way.
The result is a system that technically still works but no longer pays its way. The common tipping points we see are:
- An inverter that’s failed on a system too old to be worth repairing on its own
- Panels that have degraded or been damaged and are no longer supported
- A system far too small to cover today’s usage, let alone a battery or EV
- Output that’s dropped to the point where you’re buying most of your power again
If that sounds like your setup, replacement is often the cheaper option over the next few years, not the more expensive one.
What a Solar Replacement Includes
- Assessment of your existing system and roof
- Removal and responsible disposal of the old system
- Supply and installation of quality panels (Hyundai, Qcells, REC, Jinko and more)
- New inverter sized to your home’s usage (SolarEdge, Fronius, Enphase and more)
- Switchboard checks and any required electrical upgrades
- SAPN approval and grid connection
- System commissioning, testing and monitoring setup
When Replacement Makes Sense
Replacing isn’t always the answer, and we’ll say so if a repair is the smarter move. Replacement tends to make sense when:
- The system is more than 10-12 years old
- The inverter has failed and isn’t economical to replace alone
- Output has dropped well below what the home needs
- You’re planning to add a battery or EV charger
- Panels are damaged, degraded or no longer supported
What to Expect During a Solar Replacement
We plan the job so it’s a smooth day, not a disruption:
- We assess your existing system, roof and switchboard, and confirm the right size before quoting.
- We handle the SAPN approval and paperwork so the grid connection is done properly.
- On install day we safely remove and dispose of the old system, then fit the new panels and inverter.
- We check the switchboard and complete any electrical work the new system needs.
- We commission and test the system, set up monitoring, and show you it working before we leave.
Your home stays on mains power throughout, so the changeover doesn’t leave you in the dark.
Sized for How Your Home Uses Power
A replacement is a chance to get the system right, not just like-for-like. We look at:
- Your actual daily and seasonal power usage
- Roof space, orientation and shading
- Whether a battery is on the cards now or later
- Future EV charging load
- The feed-in and self-consumption balance that suits you
The goal is a system that fits your home, not the biggest one we can sell you.
What Affects the Cost of a Solar Replacement
Every home is different, so we quote after assessing yours. The main things that move the price are:
- The size of the new system and how much power you need it to make
- The panels and inverter you choose, there’s a genuine range from solid value to premium
- Whether the switchboard needs upgrading to take the new system
- Removal and disposal of the old system and any roof or mounting work
- Whether you’re adding, or wiring for, a battery at the same time
We explain the options in plain terms so you can choose where it’s worth spending and where it isn’t. Flexible payment options are available through Brighte.
Our Approach to Solar Replacement
We treat it as advice first, install second.
- Inspect the existing system and the home’s needs
- Explain honestly whether repair or replacement is right
- Recommend a system sized to how you actually use power
- Install it properly and stand behind the work
No pressure, no oversizing, no unnecessary work, and every installation backed by our lifetime workmanship warranty, done by our own employed technicians rather than subcontractors.
Frequently Asked Questions
Should I repair or replace my old solar system?
It depends on the age, the fault and the cost. If a repair restores reliable output economically, that’s the better call. If the system is past its useful life, replacement makes more sense. We give you the honest comparison before you decide.
How long does a solar system last?
Panels are generally built to last well beyond a decade, while inverters typically have a shorter life. An inspection tells you where your system sits and whether it’s worth keeping.
How long does a solar replacement take?
A typical home replacement is done in a day or two, depending on the system size and any switchboard work involved. We give you a clear timeframe before we start.
What happens to my old panels and system?
We remove the old system and dispose of it responsibly as part of the job, so you’re not left with panels and gear to get rid of.
Will my power be off during the installation?
Your home stays connected to the grid, so you keep mains power throughout. The solar side is switched off safely while we work, then commissioned once it’s done.
Can I add a battery when I replace my solar?
Yes, and it’s a sensible time to do it. Replacing the system lets us size and wire it so a battery integrates cleanly, now or later.
Can I just replace the inverter instead of the whole system?
Sometimes, yes. If the panels are still performing well and only the inverter has failed, an inverter replacement can be the smarter spend. We’ll tell you honestly which way makes sense for your system.
What brands do you install?
We install panels from Hyundai Energy Solutions, Qcells (including the Q.TRON AC series), REC Solar, Winaico, Jinko Solar, Seraphim and Canadian Solar, paired with inverters from SolarEdge, Enphase, Fronius, Sungrow, Solis, GoodWe and SMA. We’re happy to talk through the options that suit your home and budget.
Do you handle the grid connection and paperwork?
Yes. We manage SAPN approval and grid connection as part of the installation.
Is finance available?
Yes. We offer flexible payment options through Brighte, and your technician can talk you through it on-site.
