Australian Energy Rebates Guide
A comprehensive guide to federal and state rebates for solar, batteries, heat pumps, insulation, and more. Verify availability with the relevant program before purchasing.
Federal Programs
Federal rebate based on system size and location. Reduces upfront cost of solar PV and heat pump hot water systems.
Federal support for home battery installation when paired with solar.
How Do STCs Work?
Small-scale Technology Certificates (STCs)are the main federal incentive for solar panels and heat pump hot water systems. They can reduce the upfront cost by thousands of dollars — but many people haven't heard of them because the discount is applied automatically.
When you install an eligible system, it generates a number of STCs based on how much renewable energy it's expected to produce over its remaining lifetime in the scheme. These certificates are tradeable and have a market value (currently around $39 each).
You don't need to do anything.In almost all cases, your installer “assigns” your STCs to themselves in exchange for a point-of-sale discount on your installation. The STC value is deducted from the quote before you pay — so the “cost after rebates” figure you see in our calculator is the price you'd actually pay.
You can choose to create and sell STCs yourself through the REC Registry, but this involves paperwork and waiting for the market price. Most homeowners let the installer handle it.
The scheme is winding down.STCs are based on a “deeming period” — the number of years left until the scheme ends in 2030. In 2026, that's 5 years. Each year, the deeming period drops by one, which means the number of certificates (and the discount) gets smaller every year. The sooner you install, the larger the rebate.
