Perth solar panel installation rebates and incentives

Perth offers some rebates and incentives to households that contribute to renewable energy generation, in addition to competitive feed-in tariffs (FiTs).

Small-scale Technology Certificates in Perth

STCs are part of the federal scheme which rewards customers with a form of rebate. If you install solar panels or a solar hot water system, you will receive a number of certificates that can be sold on an open market or given to your solar installer for a hefty discount on your system.

As an example, a 6.6kW solar system in Sydney should generate 82 certificates, resulting in a reduction of $3,025, according to Solar Choice.

Battery installation incentives

Starting in July 2025, the WA Government will introduce an incentive to customers installing a new solar battery from an accredited supplier. Synergy customers can claim a rebate of $500/kWh, max 10kWh and capped at 19,000 households. Horizon Power customers can claim a rebate of $750/kWh, max 10kWh and capped at 1,000 households.

Eligible households can receive an interest-free loan of up to $10,000 to help cover solar packages and battery-only systems with up to 10 years to repay the loan. Batteries must be VPP ready and at least 5kWh.

What should I look for in a solar installer?

The role of a solar installer is to assess your individual needs, including your household’s energy consumption, usage patterns, geographical location, and financial considerations, to recommend the most appropriate solar system for you. Since different installers offer varying options and pricing, it is essential to obtain quotes from multiple providers before making a decision. Personal referrals and online reviews can be invaluable in finding a reputable solar installer.
