Our story
Warehouse-direct, because Perth asked for it.
You spoke, we listened. Drawing on 20 years of home-electrification experience, we adapted to a simple demand: high-quality, sustainable energy without the drawn-out, commission-driven sales process.
Our package-style approach streamlines buying and delivery, and our own CEC-accredited teams do the installing — 80% in-house, 20% subcontractors. Whether we assess your roof remotely or send a technician in person, the price we quote is the final amount you will pay.

What backs the badge
The guarantee is a double layer, not a slogan.
A product warranty is only as reliable as the company servicing it. We stay responsible for every claim, including the manufacturer ones.
One honest price
The number we quote is the number you pay. Remote or in-person assessment, itemised so you can see what every dollar buys, and no moving goalposts once you have said yes.
PSW Life Support
A double-layer product and installation guarantee we own ourselves, plus monitoring help and system health checks for the life of your system.
Here in ten years
A warranty is a promise about the future, so it is only worth what the company behind it is. We have been trading in WA energy since 2004.
