  • Reduce or eliminate your electricity bill
  • Earn feed-in tariff credits for surplus energy exported to the grid
  • Access federal and state government rebates that lower your upfront cost
  • Protect yourself from ongoing electricity price rises
  • Increase your property value - solar adds an average of $15,000–$30,000 to home valuations in NSW

Are There Government Rebates for Solar Panels in NSW?

Save Thousands Before You Install

NSW homeowners and businesses can access several government incentives in 2026 that significantly reduce the upfront cost of installing solar panels. These rebates are subject to annual changes - acting sooner locks in higher savings.

Federal STC Rebate (Small-scale Technology Certificates)

The federal government’s STC scheme is the primary solar rebate available to all Australian households and businesses. In 2026, the deeming period is 5 years (reduced from 6 in 2025), which means the rebate is worth approximately $3,500 – $4,500 on a 6.6kW system, depending on current STC market prices. For this reason, Isolux processes your STC paperwork as part of every installation – you receive the rebate as an upfront discount, not a delayed payment.

  • Available to all residential and commercial solar installations
  • Applied as an instant point-of-sale discount – no forms to fill in
  • Rebate reduces by one year’s worth each January – the sooner you install, the more you save

Federal Cheaper Home Batteries Program (from July 2025)

From July 2025, the federal government launched the Cheaper Home Batteries Program, which provides a 30% discount on eligible home battery installations – equivalent to approximately $336 per kWh of usable capacity. On a 10kWh battery system, this represents a saving of over $3,300. This program is available until all allocated funding is exhausted.

  • 30% off the cost of eligible battery systems
  • Available in conjunction with a new or existing solar system
  • Applies to batteries installed from 1 July 2025
  • Ask Isolux about compatible battery options, including the Tesla Powerwall

NSW Virtual Power Plant (VPP) Incentive – Up to $1,500

NSW residents who connect their home battery to a Virtual Power Plant (VPP) can receive up to $1,500 in incentives. VPPs allow your battery to contribute to grid stability during peak demand periods – you benefit financially while helping reduce strain on the NSW electricity network.

Feed-in Tariffs

Every kilowatt-hour of unused solar energy your system exports to the grid earns you a feed-in tariff credit on your electricity bill. Feed-in tariff rates in NSW currently range from 5-9 cents per kWh, depending on your retailer. Isolux can advise on the best retailer and tariff arrangement for your system size and usage pattern.

Therefore, Isolux designs and installs commercial solar systems from 10kW to 100kW+ across Sydney. Our commercial team manages the entire project - from system design and permitting through to Distributed Network Service Provider (DNSP) approval and commissioning.

Commercial Solar ROI in Sydney

A typical 30kW commercial solar system in Sydney generates approximately 42,000-45,000 kWh per year. At an average commercial tariff of 28-38 cents per kWh, this translates to annual savings of $12,000-$17,000. Consequently, with system costs starting from $25,000 after rebates, most Sydney commercial installations achieve full payback within 2-4 years.

How Solar Panels Work

From sunlight to savings

Your panels capture sunlight, your inverter converts it into usable electricity, and your home runs on clean energy - any surplus is exported to the grid for a feed-in credit.

Solar panels convert sunlight into direct current (DC) electricity using photovoltaic (PV) cells. This DC electricity is then converted into alternating current (AC) by the inverter – the form of electricity used in your home or business. Meanwhile, any surplus energy your system generates is exported to the grid, earning you a feed-in tariff credit on your bill.

  • Panels absorb sunlight and generate DC electricity
  • Inverter converts DC to AC electricity for household use
  • Your home uses solar electricity first – reducing grid consumption
  • Surplus power is exported to the grid and credited to your account
  • At night or on overcast days, your home draws from the grid as normal
  • Add a battery to store surplus energy and use it at night

Solar Battery Storage in Sydney

2026 Rebates Available

With the federal 30% battery rebate now available, there has never been a better time to add storage.

With the federal Cheaper Home Batteries Program now offering 30% off battery installations, 2026 is the best time to add storage.

  • Store surplus solar energy and use it after sunset
