Our Services

Solar Installation

Complete residential solar panel systems designed and installed by our in-house CEC accredited team. From 6.6 kW starter systems to 20 kW+ large home setups.

Battery Retrofits

Already have solar? Add a battery to your existing system. We supply and install Hinen and Sigenergy batteries to maximise your self-consumption and provide blackout protection.

Increase System Size

Already have solar but need more power? We add extra panels to your existing system. We replace old panels, inverters and wiring to bring your system up to current standards and maximise output.

Monitoring & Maintenance

We monitor your system performance remotely. If something drops off, we catch it early. Includes panel inspections, inverter health checks and cleaning recommendations.

Grid Connection Applications

We handle all Energex (QLD) and SA Power Networks (SA) grid connection paperwork on your behalf. No forms to fill out, no phone calls to make — we manage the entire process.

Increase Battery Size

Want more storage from your existing battery? We add extra modules on site or remove and replace the entire setup with modern, high-efficiency equipment. Includes disposal of old panels and full re-commissioning.
