Solar Rebates in WA 2026: Complete Guide for Perth Homeowners
If you’re considering solar panels for your Perth home in 2026, you’re in luck. Australia continues to offer some of the most generous solar incentives in the world.
Here’s everything you need to know about the rebates and incentives available to Western Australian homeowners right now.
The Small-Scale Technology Certificate (STC) Scheme
The federal government’s Small-Scale Renewable Energy Scheme (SRES) remains the biggest financial incentive for going solar in 2026.
When you install a solar system, you receive Small-Scale Technology Certificates (STCs) based on the amount of renewable energy your system is expected to generate over its lifetime.
For a typical 6.6kW solar system in Perth, you can expect to receive approximately $2,800 to $3,200 in STC value as an upfront discount on your installation cost. This is applied at the point of sale, meaning you pay less on the day of installation.
How STCs Work
- STCs are calculated based on your system size and location (Perth’s sunny climate means more certificates)
- The number of STCs decreases each year as the scheme phases down toward 2030
- Your installer (like Talk Energy) handles the STC paperwork and applies the discount
- The sooner you install, the more STCs you receive
WA Feed-in Tariffs
When your solar panels produce more electricity than you use, the excess is exported to the grid. In Western Australia, Synergy offers a feed-in tariff for this exported energy.
The current rates are reviewed periodically, so it’s important to check the latest rates when planning your system.
Key points about WA feed-in tariffs:
- Distributed Energy Buyback Scheme (DEBS) provides tiered rates for exported solar energy
- Peak export times (3pm-9pm) typically earn a higher rate
- Off-peak export earns a lower rate
- Adding battery storage can help you use more of your own solar energy rather than exporting at lower rates
How Much Can Perth Homeowners Save?
Perth enjoys an average of 8.8 peak sun hours per day, making it one of the best cities in Australia for solar. A well-designed solar system can reduce your electricity bills by 50-80% or more.
Here’s a typical savings breakdown for a Perth household:
- 6.6kW system: Save $1,200-$1,800 per year on electricity
- 10kW system: Save $1,800-$2,500 per year
- 13.3kW system: Save $2,200-$3,200 per year
- With battery storage: Additional $500-$1,000 savings per year
Tips to Maximise Your Solar Rebate
- Install sooner rather than later — STC values decrease each year as the scheme phases down
- Choose a quality installer — A properly designed system generates more energy and more savings. At Talk Energy, our in-house electricians ensure every installation is optimised for your roof
- Right-size your system — An oversized system won’t necessarily earn you more. We’ll assess your actual energy usage to recommend the ideal size
- Consider battery storage — With feed-in tariffs lower than retail electricity rates, storing and using your own solar power is increasingly valuable
- Use our Solar Calculator to estimate your potential savings

Frequently Asked Questions
What are the eligibility criteria for solar rebates in WA?
To qualify for the federal STC rebate in Western Australia, your system must be installed by a CEC-accredited installer using CEC-approved panels and inverters. The system must be under 100kW, and the property must have a valid electrical connection.
Both owner-occupied and rental properties are eligible. Talk Energy handles all the rebate paperwork so you receive the discount at the point of sale.
How do I apply for the STC rebate?
You do not need to apply separately for the STC rebate. Your solar installer creates the Small-scale Technology Certificates on your behalf and applies the rebate as an upfront discount on your system price.
When you get a quote from Talk Energy, the STC rebate is already factored into the final price, making the process seamless for Perth homeowners.
Will solar rebates decrease in the future?
Yes, the STC rebate is legislated to reduce by one-fifteenth each year until it phases out completely on 1 January 2031. This means the rebate you receive today is higher than what will be available next year.
For Perth homeowners considering solar, acting sooner rather than later will lock in a larger rebate and deliver faster savings on electricity bills.
