Solar Rebates and Incentives Perth 2026

Solar remains one of the best investments for a Perth home, and several incentives can bring the upfront cost down. Knowing what's available helps you judge whether a quote is genuinely competitive.

Federal STCs

The federal small-scale technology certificate (STC) scheme effectively discounts the cost of a new system at the point of sale. Most Perth installers build this into their quoted price rather than you claiming it separately.

What to Check on a Quote

• Whether the price is after the STC discount or before
• That the installer and panels are Clean Energy Council accredited
• The inverter brand and its warranty, not just the panel warranty

Feed-in Tariffs in WA

Western Australia's Distributed Energy Buyback Scheme pays a rate for excess energy you export, with different rates for different times of day. Because the daytime rate is modest, sizing your system to your own usage often matters more than maximising exports.

Batteries

Battery incentives change periodically, so ask your installer what's currently available. Run the numbers on payback before adding storage — it isn't right for every household yet.
