A lot of solar companies are sales companies with subcontracted installers. We're the opposite, licensed electrical contractors in NSW and QLD who design, install and stand behind every system ourselves.
We size systems from how you actually use power, not from a one-size-fits-all package. That's the difference between a battery that carries you through the night and one that dies at 9pm.
Every job to AS/NZS 3000, 5033 and 5139, with the switchboard, cabling and protection done properly. It's the part of the job you can't see that decides how long a system lasts.
We're local, we answer the phone, and we service what we sell. Off-grid clients rely on us for power every day, that's the standard everything we install is held to.
Every home and property is different, but these packages show what a properly specified system looks like, and roughly what it costs installed. Pick the closest fit and enquire; we'll design the exact system around your loads, your roof and your switchboard.
* Typical installed price range for a straightforward single-storey tin roof. Final pricing confirmed after site assessment. All systems use Winaico BDX Midnight panels with a full 30-year product warranty and Sigenergy hybrid inverters, battery-ready from day one.

A solar and battery system is a 25-year asset bolted to your biggest asset. Ours are specified so the system you buy in year one is still the system earning for you in year twenty.
Premium panels degrade slower, so the gap between a quality array and a cheap one widens every single year. Over a system's life that's thousands of kilowatt-hours of extra production from the same roof space, and it's why we put Winaico's 25-year product warranty on every home.
Every brand we install has a real Australian office, and we're still here to make the call with you. A warranty is only worth the company standing behind it in year fifteen, that's the actual difference between the quotes you're comparing.
The craftsmanship you can't see from the driveway, switchboard work, cable protection, waterproof penetrations, is what decides whether a system runs quietly for decades or becomes a callback machine. Our own licensed team does every install, and we service what we sell.
WinaicoPremium panels with a full 25-year product warranty, not just a performance promise, backed by a local Australian office. We've installed Winaico for years across coastal salt, hinterland humidity and Pilbara heat, and they just keep performing. We fit the BDX 485 W on homes and the NCX 520 W on commercial roofs, when our name is on the roof, this is the panel we trust under it.
SigenergyOne integrated stack, hybrid inverter, modular battery and optional DC EV charging, that expands whenever your needs grow. Fast blackout switchover, a genuinely good app, and clean installs every time.
VictronThe off-grid industry standard, and what we build our remote systems on. Decades of proven reliability, endlessly configurable, with remote monitoring that lets us support a system in the Pilbara from the Tweed.
XESSAustralian-based battery brand using prismatic LiFePO₄ cells, manufactured offshore to keep the price sharp without cutting cell quality. The value pick in our storage lineup, and like everything on this page, it earned its place on our own jobs first.
MPSAustralian-made LiFePO₄ storage built on prismatic cells, serious battery banks for hard duty cycles. Our storage of choice on big off-grid builds, including 200 kWh systems running whole properties day in, day out.
Fully off-grid power delivered in one of the most remote corners of the country, engineered for Pilbara heat and total self-sufficiency.
Commercial-scale off-grid running an entire property on three-phase power, day and night, with no grid connection at all.
Large commercial rooftop cutting daytime grid draw to near zero and shifting stored solar into the evening peak.
A major community facility in our own backyard, big daytime loads offset by solar, with storage carrying the site into the evening.
Complete commercial electrical package delivered to standard, the contracting backbone that sits behind our renewables work.
Properly sized solar and battery systems for homes across the Tweed, Northern Rivers and SE QLD.
"Jasper and the team installed a 7kW solar system with a 16kW Sigenergy battery on our house when our old system died. Our electricity bill dropped from $250+ a month to $9, and we had power through 4 days of grid outages when Cyclone Alfred hit. Easy to deal with, turned up on time, and the app is super easy to use."
Debbie Gallard · Google review"Jasper and crew installed our 20kW solar system with 32kW of batteries, upgraded our switchboard and installed 2 air conditioners with minimal fuss. Workmanship and communication were first class. This is the second job Thomson Energy have done for us and the result is exactly what we wanted. 100% recommended!"
Jeff Budd · Google review"Thomson Energy is extremely knowledgeable and professional. We got great advice and the job done in a short time, competitive prices and fantastic service. Easy to communicate with. Extremely happy with the team."

Alongside residential work, Thomson Energy delivers commercial solar and electrical packages for builders, developers and facility operators, including tendered solar installations for national construction companies and aged-care providers.
About us
The Thomson name has been on solar and electrical work in this region since 2011, when the business began as Thomson Solar, a father-and-son operation built on doing the job properly. Today, Thomson Energy carries that same standard forward from our base at Fernvale in the Tweed Valley, delivering solar, battery and off-grid projects across the whole of New South Wales, Queensland and Western Australia.
We're an 11-strong team of licensed tradespeople, apprentices and support staff, big enough to deliver 90 kW commercial arrays and remote off-grid builds on the other side of the country, small enough that the people who design your system are the ones who install it and answer the phone afterwards. No call centres, no subcontracted sales.
Tell us a bit about your place and what you're trying to achieve. We'll come back with straight answers and a properly designed system, not a hard sell.
