Cost & sizing
How much does solar or a battery actually cost?
A quality 6.6kW solar system can land as low as $5,500 once the government rebate is applied. A quality 9.6kWh battery typically starts around $9,000 before any rebate.
What size solar system do I need?
Households using 15–20kWh a day usually do well on a 6.6kW system. Using more like 20–40kWh a day — or planning ahead for a pool, ducted air-con, an EV or a battery — and we'd usually point you toward a 10.5kW–13.2kW system instead. It's almost always cheaper to size it right up front than to add a second system later.
What size battery do I need?
9.6kWh or 12.8kWh covers most households. The right number really depends on why you want a battery in the first place — backup power for outages is a different design problem to covering your evening usage and keeping you off the grid overnight. Our designers work through that with you case by case.
How long will it take to pay off my system?
Most customers see their system pay for itself within 3–5 years, depending on your current power bill, your feed-in rate and how much you use at night.
Installation & timeline
How soon can you install our solar or battery system?
Typically within 2–3 weeks of signing the contract.
How long does the install itself take?
Between 4 and 8 hours depending on the system size and your roof type — most installs are finished in a single day.
Do I need to upgrade my switchboard or meter?
If your meterbox doesn't have a hinged door and your property doesn't already have solar, Energex or Ergon will require the meterbox upgraded to current standards before your system can be connected.
How long does Energex/Ergon take to replace a meter?
Typically 15 business days.
Can I finance the cost?
Yes — $0 upfront options, plus low fixed-interest and no-interest finance from 24 to 84 months.
How and when do I set up or change my feed-in rate?
Once your install is complete, we contact Energex/Ergon on your behalf and request an EWR — they'll let you know if your meter needs upgrading. Hold off changing your electricity provider or plan until your meter's sorted. As a rough guide in early 2024, a decent feed-in rate sat around 12c/kWh uncapped, alongside a consumption rate of roughly 32c/kWh — worth checking current rates when you're ready.
Warranty & rebates
What warranty does my system come with?
Inverters and batteries come with a 10-year manufacturer warranty, and panels carry 25–30 years depending on the brand. Every installation is also backed by our own 10-year workmanship warranty, covering our end of the job.
Is there a government rebate to help with the cost?
Yes — in Queensland, there's currently a maximum $8,000 solar rebate and $4,000 battery rebate available if you qualify. We're proudly one of the few fully registered solar and battery installers approved to offer rebate installations directly — ask us for the details that apply to you.
Panel care, roofs & upgrades
How often should I clean my solar panels?
On roofs pitched at 22.5° or steeper, once a year with a soft broom and soapy water is usually enough. Under 22.5° pitch, twice a year is better. We also offer an ongoing cleaning service if you'd rather leave it to us.
Does my roof need restoring before solar goes on?
Sometimes. If a tile roof needs cleaning, re-pointing or painting first, we offer a two-stage install: we fit the mounting feet, your roof gets restored, and once it's cured we come back to finish the solar install. We work closely with a local roofer who can handle the restoration for you.
What about bird-proofing?
We install black plastic or steel mesh around the perimeter of your system to stop pigeons and possums nesting underneath — it can usually be done the same day as your install.
Can I replace or add to my current solar system?
If your roof has the space and can carry the extra load, yes. Talk to one of our designers first so any addition is actually sized to suit your home rather than just bolted on.
What happens if my panels are damaged by hail?
Hail is a genuine risk across South-East Queensland. Damage is usually covered under the panel's product warranty for a full replacement, generally within weeks. Call us as soon as it happens and we'll process it for you.
Inverters, shading & technical details
What battery is compatible with my existing inverter?
Most existing solar systems can take an AC-coupled battery — Tesla and Sonnen are two we'd consider. If budget's tighter, Sungrow SBR and BYD HVM batteries are a strong fit, especially if you already run a Sungrow Hybrid or Fronius Gen24 inverter.
Are micro-inverters worth it?
Micro-inverters like Enphase are a great option if your roof has limited space or heavy shading, since they let you monitor each panel individually. If your roof gets good sun and has room to spare, a standard string inverter will usually save you $2,000+ off the install.
What if I have shade from nearby trees or buildings?
Shade is genuinely one of solar's biggest enemies — production can drop off fast once panels lose direct sun. Trimming or removing trees helps where you can, but if the shade's coming from something outside your property, we can offer a micro-inverter or optimiser setup to soften the impact.
Are solar inverters noisy?
We don't install budget inverters, which solves most of the noise problem outright. The higher-end units we do use can still have a faint fan noise, so we'll often recommend installing them in the garage or outside near the switchboard, away from living areas.
Should the inverter go inside the garage or outside?
Inside tends to mean better protection from weather and vermin, plus a steadier WiFi connection. Outside usually means less noticeable noise and better airflow, with IP-rated weatherproofing built in. We'll assess your specific install before deciding which suits you.
Is it possible to hide the cable runs?
In most cases, yes — DC and AC cabling can run through wall and ceiling cavities instead of surface-mounted conduit. Where that's not possible, we run external conduit as neatly as we can to match the look of your home.
Do I need a smart meter or consumption monitoring?
A smart meter feeds your monitoring app with production, consumption, export and battery data, and lets you cap how much you export to the grid if needed. Not everyone needs one, but it's worth discussing if you want more visibility over your system.
Do I need to let my insurer know about a new solar system?
It's worth a call to your insurer to check whether solar and batteries are covered under your home and contents policy.
What happens if my system shows a fault or error code?
Most faults show up as a red light on the inverter or battery, and on your phone monitoring app. Follow the safe shutdown procedure printed on the unit and call us straight away — we'll get a technician out as soon as we can.
What if my system shows offline on the app?
It's usually a WiFi issue — the dongle under the inverter's been bumped, your modem's been moved, the inverter password's changed, or the NBN's been switched over.
Where do old solar panels go once removed?
We work with a not-for-profit that ships still-working panels overseas to help farms and communities that need them. Panels that are broken or damaged get converted into PVcrete, a concrete alternative — we try to keep as much out of landfill as we reasonably can.
Batteries
Are batteries actually safe to install in my home?
Every battery we install is lithium iron phosphate (LFP) chemistry — less prone to combustion and thermal runaway than older lithium-ion cells, with a cycle life rated up to five times longer.
Can I run my entire house off a battery, or only sections of it?
Once your battery's charged up, your whole house can run on stored power in the evening instead of buying from the grid. For emergency backup during an outage specifically, we usually recommend limiting that to a kitchen circuit and a central lighting circuit — most inverter-battery combinations can't handle the full house load in an outage without draining the battery faster than you'd want.
Do I need a hot water timer or CATCH Power?
If you've got solar and an electric hot water system, we'd recommend a hot water timer or a CATCH Power relay. It lets your hot water run off your normal power circuit instead of a separate off-peak meter, so it can actually benefit from your solar instead of buying grid power overnight.
