State-by-state solar & battery rebates explained

The federal layer

Every eligible system in Australia earns STCs (Small-scale Technology Certificates), which your installer typically applies as an up-front discount. From 2026 the Cheaper Home Batteries Program adds a separate discount for battery storage.
