New South Wales Solar Installer
NSW Home Energy Saver: up to $15,000 interest-free for solar and batteries →From the Hunter to the Illawarra, Energy Systems Australia designs and installs solar and battery systems for NSW homes and businesses. Every system is sized to your roof, your usage and your network's rules, never one-size-fits-all. Our NSW base is in Gledswood Hills in the Macarthur region, and our commercial work includes a 100 kW system at Tuggerah on the Central Coast.

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.

Explore battery storage →Commercial Solar
Rooftop systems for warehouses, workshops, retail and farms. Our delivered commercial jobs run from 66 kW to 100 kW, and eligible business systems up to 1 MW can now claim the upfront STC discount.
Explore commercial solar →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.

Solar rebates in NSW

NSW Home Energy Saver interest-free loan
Borrow up to $15,000 at zero interest for rooftop solar and home batteries, and repay it over up to 10 years. It's open to property owners, including landlords, with a combined taxable household income of up to $210,000. Federal discounts come off the price first, and the loan can cover the rest. Discounts of up to $4,000 for lower-income households are coming soon.
Federal solar rebate (STCs)
Small-scale Technology Certificates cut the upfront cost of an eligible system, applied as an instant discount.
Mid-scale business solar
From 1 October 2026, eligible systems above 100 kW and up to 1 MW can claim STCs, with a fixed five-year deeming period.
Cheaper Home Batteries Program
Around 30% off an eligible battery for homes and small businesses. With no NSW battery installation rebate for households right now, this is the main home battery discount.
NSW business battery incentive
Since 1 September 2026, eligible business batteries from 20 kWh to 30 MWh can get an upfront discount, which the NSW Government puts at around 20 to 40% of battery cost.
