What solar rebates are available in Sydney?

Small-scale Technology Certificates (STCs) are a federal government incentive in which homeowners receive certificates for the solar energy their system will generate over a set period. These certificates can then be sold to help offset the upfront cost of installing solar panels. To know if you qualify for this incentive, please get in touch with our team.

See if you qualify

Is there a solar battery rebate available in Sydney?

Yes. Starting 1 July 2025, you can access the new federal battery rebate under the Cheaper Home Battery Program. This nationwide program offers up to 30% off the cost of eligible home batteries.

The subsidy amount varies based on your battery's usable capacity. In 2025, the estimated amount is around $370 per kilowatt-hour (kWh). If you install a battery with a usable capacity of 10 kWh, your rebate would be around $3,700.

Moreover, the rebate amount will decline annually, so the sooner you install your battery, the more you save.

How much do solar systems cost in Sydney?

The cost of fully installed solar panels in Sydney can vary depending on the size of the system and your home's setup. But here is a general guide to help you estimate the cost of your system.

Prices for a solar panel system typically start from around $1.20 per watt, including the components and the standard installation. So, if you are eyeing a 7 kW system, you'd be looking at approximately $8,400. You can easily estimate your cost by multiplying the system size in watts by $1.20.

If you want to add a battery, pricing usually starts from $1,500 per kilowatt-hour, excluding rebates. For instance, a 5 kW battery would start from around $7,500 installed.
