WA solar panels: An investment with great returns
For a 6.6 kW solar system in Western Australia, homeowners can expect to save between $1,000 and $1,500 annually, depending on their electricity usage and whether they include battery storage. This estimate is based on the current feed-in tariff (FiT), which varies from 8 to 15 cents per kilowatt-hour (kWh).
For larger systems, such as a 10 kW solar setup, annual savings can reach up to $2,700, especially for households with higher self-consumption rates or those on time-of-use tariffs. These savings highlight the financial benefits of investing in solar energy for homes across Western Australia.
By leveraging available government incentives and the growing affordability of solar technology, residents can make a wise investment in their energy future.
WA rebates and incentives
WA residents and businesses can benefit from several state and federal incentives and rebates, including:
- Small-scale Technology Certificates (for residential and small to medium businesses)
- Feed-in Tariffs
- WA Residential Battery Scheme (commencing 1 July 2025)
- Distributed Energy Buyback Scheme (DEBS)

Energy efficient products and upgrades
Upgrade your outdated appliances to the latest energy-efficient technology to save significantly on energy costs. Older systems, like hot water heaters, heating and cooling units, and other household devices, may be costing you thousands each year. By replacing them, you can reduce your environmental impact while enhancing your home’s efficiency.
In Western Australia, installing a solar hot water system can save households between $300 and $800 annually on energy bills, depending on hot water usage and the system’s type. These systems harness solar energy to heat water, decreasing reliance on traditional electricity or gas sources, and making them both cost-effective and environmentally friendly.
Western Australian residents can benefit from various incentives, including Energy Ahead, which offers support for upgrading to energy-efficient products for residents experiencing financial hardship.
WA solar batteries: The future of renewable energy
In Western Australia, 25% of all new solar systems installed in 2024 included battery storage. Adding a battery to your solar setup allows you to enjoy power savings around the clock. Not only do solar panels and batteries enhance your home’s value, but they also significantly reduce energy bills and increase your energy independence from the grid.
Batteries are regarded as the future of energy, enabling you to store solar power generated during the day for use at night or on cloudy days when sunlight is limited. Incorporating a battery with a residential solar system can potentially double your self-consumption of generated electricity.
To maximise your battery’s potential, consider joining a Virtual Power Plant (VPP). This initiative can shorten the payback period for your battery investment and provide additional income by selling your stored energy back to the grid during peak demand periods.

WA Battery Rebate: Residential Battery Scheme
The Western Australian Government is launching the WA Residential Battery Scheme to help households install home battery systems. This initiative aims to reduce energy bills, support local jobs, and boost renewable energy use.
What is the scheme?
Starting on or before 1 July 2025, the scheme offers rebates and no-interest loans for installing home batteries. It complements the Federal Government’s Cheaper Home Batteries Program, providing combined support of up to $5,000 for Synergy customers and $7,500 for Horizon Power customers.

To qualify, you must:
Own a residential property in Western Australia.
Have an electricity account with Synergy or Horizon Power.
Not be a government, financial, telecommunications, or mining entity.
Agree to participate in a Virtual Power Plant (VPP).
Install an approved battery system after the scheme’s commencement.
Households earning less than $210,000 annually can access no-interest loans up to $10,000, repayable over 10 years. These loans can cover batteries, inverters, and solar panels, provided they’re installed with a battery.
How much can you get?
Rebates are based on battery capacity
Synergy customers: $130 per kWh, up to $1,300.
Horizon Power customers: $380 per kWh, up to $3,800.
Combined with federal support, total rebates can reach $5,000 for Synergy and $7,500 for Horizon Power customers.
This scheme is part of a $337 million investment to make home batteries more accessible, aiming to benefit up to 100,000 households.
The Electric Vehicle (EV) movement is rapidly expanding in Australia. Are you prepared for the shift to electric?
Did you know that about 50% of Western Australians are considering purchasing an electric vehicle (EV) within the next five years? Installing a home battery not only enables you to charge your EV overnight but also allows you to sell any excess stored electricity back to the grid. This flexibility lets you choose the best option for your needs, tailored to your lifestyle and the current feed-in tariff.
With residential EV charging, you can transform your home into a personal charging station, significantly lowering your vehicle costs and enhancing your convenience. The expanding EV market in Western Australia, where EVs made up approximately 7.4% of all vehicle sales in 2022, indicates a positive shift towards sustainable transport options
