Why solar works here

Solar power built for New South Wales

NSW gets strong, reliable sunshine from the Hunter Valley to the south coast, and with grid prices climbing, every kilowatt you generate and use yourself is money kept in your pocket. The best system for a weatherboard home in Maitland is not the same as one for a coastal roof in Wollongong or a warehouse in Tuggerah, so we design each one from scratch.

Upfront cost is less of a hurdle than it used to be. Through the NSW Government's Home Energy Saver program, eligible homeowners and landlords can borrow up to $15,000 interest-free for solar and batteries, and repay it over up to 10 years.

We're not a one-size-fits-all installer. As SAA-accredited designers and installers, we assess your roof, your power bills and your local network's connection rules, then build a system that delivers real, reliable output backed by quality panels, inverters and solid warranties.

Know before you buy

What shapes a good NSW solar system

Three things every NSW solar quote should account for.

Two networks, two rulebooks

The Hunter and Central Coast sit on the Ausgrid network; the Illawarra and Macarthur sit on Endeavour Energy. Each sets its own connection and export rules, and we design to the one at your address.

Coastal roofs

Homes near the coast in Newcastle, the Central Coast and Wollongong need corrosion-rated mounting and hardware to last the life of the system.

Batteries for business

Since 1 September 2026, NSW businesses can get an upfront discount on battery storage. Pairing a battery with new solar earns a higher rate, so it pays to plan both together.
