Panels, inverters & batteries we install



Residential Solar
A grid-connected array designed around your actual consumption and unshaded roof — not a package number. We lodge the network application, install with our own SAA accredited team and hand over a documented, monitored, warranted system.

Ideal for



Battery Storage
A battery holds the surplus your panels make during the day and runs your home at 7pm — instead of exporting it for cents and buying it back at peak rates. Sizing starts with your overnight consumption pattern, not a brochure capacity.
Options
Ideal for



Commercial Solar
Larger rooftop systems engineered for compliance, yield and long-term reliability. One team carries the project from feasibility through to commissioning, including the distributor application and the compliance paperwork.
Typical scale
Ideal for



Industrial & EPC
Our full EPC offering for projects where design, supply and construction need to sit with one party. Grid-code compliant design, certified equipment through vetted vendors, field quality monitoring throughout.
Scope



Ground Mount & Off-Grid
Where roof space is limited, shaded or structurally unsuitable, a ground-mounted array gives you the orientation the roof couldn’t. For sites with no viable grid connection, we design battery-backed off-grid systems sized to real daily demand.
Ideal for



Maintenance & Monitoring
Output drifts quietly. Soiling, a failed optimiser or an inverter fault rarely announces itself — it shows up months later as a disappointing bill. Remote monitoring flags underperformance early, and scheduled cleaning keeps the array doing what the design promised.

Three starting points. Every job begins with a free energy audit so the system is sized to your actual bill — not a package label.

Solar grid connection involves your distributor and retailer. Here’s the whole path, honestly described.
We review your usage data, roof layout and switchboard, then size the system to what you actually consume — not what looks good on paper.
A layout for your specific roof, an estimated annual output and a written quote stating products, total price and timeframe — before you commit.
We lodge the network connection application, then our in-house SAA-accredited crew completes the installation in a single day for most residential jobs.
Full testing, compliance sign-off, distributor paperwork and remote monitoring setup are included on every system we install.
Why Green Tree Solar
We review your usage, roof and switchboard before recommending a system — every single time.
SAA-accredited technicians employed by us complete every job. No subcontracted crews, ever.
Panels, inverters and batteries from vetted suppliers with full manufacturer warranties in place.
Products, total price and timeframe stated clearly before you commit to anything at all.
In their words
Collected directly from customers after handover — not from a review platform.
The energy audit was the part that impressed us most — they came out, looked at our actual bills and roof, and told us honestly what would and wouldn’t work. No upsell, no pressure. Install was done in a single day by the same crew who quoted us. First quarterly bill was $31. We’ve told every neighbour.
Three companies quoted us. Two gave us a PDF with specs and a price. Green Tree Solar walked us through exactly how the system was sized to our daytime consumption pattern. Different conversation altogether. The monitoring app they set us up with paid for itself the first week when it flagged a panel shading issue.
Already had a 6.6 kW system from 2021. Green Tree Solar checked whether our existing inverter could handle a battery before agreeing to do the job — another installer had already said yes without checking. Honest call saved us from buying equipment that wouldn’t have worked. Retrofit took about five hours.
Being NETCC Approved meant the consumer code protections applied — that was important to us before committing. The paperwork on our end was minimal; they handled the network application and the metering changeover. System has been producing more than the estimate since day one.
Why it works
Every installation comes with the same four commitments — no exceptions, no tiers.
Employed by us, not subcontracted. One team designs, installs and stands behind the work.
We review your bills and roof before recommending anything.
Products, price and timeframe in writing before you commit to anything.
If it fails because of how we installed it, we fix it.
Performance flagged early — before you notice the drop on your bill.
Grid-code compliant. Full EPC. One accountable team.
New installs and retrofits. Sized to your evening consumption, not a brochure number.
