solar rebates in wa

When you install a solar system, you generate Small Technology Certificates (STCs), which are sometimes referred to as a ‘Government Solar Rebate’. You’ll receive 1 STC for every Megawatt of energy your system is expected to produce until 2031.
For example, a 5kW system (approx 17 panels) will produce around 88MWh worth of electricity over the 11-year period until 2031, meaning you are entitled to 88 STCs.

Once your system has been installed and the STCs have been registered, they can be sold to recover a portion of the cost of purchasing your solar PV system. Given the complexity surrounding creating and selling STCs, it’s common practice to assign the right to create the STCs to your solar provider, in exchange for an upfront discount off the full, or ‘true’, system price.

STCs currently trade for around $37 each, which means you’d receive around $3,250 discount off the full, or ‘true’, cost of a 5kW system.
