What this means for your quote
Rebates are claimed against the exact model number installed, on the day it is installed. Approvals expire and products are occasionally removed between quote and installation, so if your install date is months away, it is worth re-checking this page or asking your installer to confirm the model is still listed. We refresh this data automatically as the Clean Energy Regulator publishes updates.
Checking a solar quote?
The solar rebate (STCs) only applies to approved products installed by an accredited installer. Answer a few questions and we will estimate your rebate and match you with installers who only quote approved gear.
