The federal government's Small-scale Technology Certificate (STC) scheme is currently active and provides a significant upfront discount automatically applied to your installation cost. It is calculated on your system size and location, and your installer applies it directly so you only ever pay the reduced price. If you are adding a battery, the separate federal battery scheme may also apply. Get a quote to see exactly how much you save.

How much does solar cost in WA?
The figures below are a rough guide based on current WA market pricing after the federal STC discount. They are not a quote. Prices vary by system size, panel and inverter brand, roof and site complexity, so your fixed-price quote will confirm the actual price for your property.
6.6kW system
Suits smaller or lower-usage households. Covers typical daytime usage with excess exported to the grid.
10kW system
A common choice for WA family homes with higher usage, pools or air conditioning. Covers more of your daytime use.
Solar + battery
Solar plus a home battery. Use solar day and night and cut grid use. The federal battery scheme may reduce this further.
EV charger
Charge your EV from solar during the day. Best installed alongside solar to reduce labour costs.
These figures are a rough guide only, based on current WA market data, and are not a quote. Actual pricing depends on your roof, system size, panel brand and site complexity. Your free quote will confirm the exact price for your specific property. There is no obligation to proceed.
Why go solar in WA?
Western Australia has some of the best sunshine in the country and rising electricity prices. Here is what makes solar a strong investment for WA homes.
Rising electricity costs
WA electricity prices have climbed in recent years. Solar offsets your daytime usage and reduces how much expensive grid power you buy.
Strong solar resource
WA gets strong, reliable sunlight across the year, from Perth and the coast to the inland regions, making solar highly productive statewide.
Feed-in tariff credits
WA has its own feed-in scheme that pays more for power exported in the evening peak than at midday, which rewards storing your solar.
WA battery rebate
WA has an active state battery rebate that can be combined with a federal battery scheme. Your installer will confirm what currently applies when they quote.
Solar EV charging
Charge an electric vehicle from solar during the day. A home EV charger installed alongside solar is one of the higher-return upgrades available.
25-year warranty
Quality solar panels carry a 25-year performance warranty. With typical payback in 3 to 5 years, that leaves many years of low-cost generation.
Common questions about solar in WA
What WA homeowners ask before getting a quote.
As a rough guide, after the federal STC discount a 6.6kW system in WA is commonly around $5,000 to $7,000, and a 10kW system around $8,000 to $11,000. Solar plus a battery commonly runs $13,000 to $18,000. An EV charger adds roughly $1,500 to $3,000 installed. These are guide figures only, not a quote. Your fixed-price quote will confirm the exact cost for your property and system size.
For solar panels, the main support is the federal Small-scale Technology Certificate (STC) scheme, an upfront discount applied by your installer. WA does not run an ongoing state rebate for solar panels. For home batteries, WA has an active state battery rebate that can be combined with the federal battery scheme. Your installer will confirm exactly what applies when they quote.
WA has its own feed-in scheme that uses a time-of-export structure. Power you export during the evening peak is worth more than power exported in the middle of the day. This rewards using or storing your own solar during daylight hours. The bigger saving from solar usually comes from using your own power rather than the credit for exporting it.
After accepting your quote, most installations are completed within 2 to 4 weeks depending on grid connection approvals and scheduling. The installation itself typically takes one day for a standard residential system. Your installer will give you a specific timeline when they call.
Most roofs are suitable. North-facing roofs at 15 to 30 degree pitch get the best results, but east and west-facing installations still perform well. Your installer will assess your roof during the quoting process and advise on the best panel positioning and any shading considerations. There is no cost for this assessment.
A battery stores excess solar generated during the day so you can use it at night, cutting your grid use. It makes the most sense if you have high evening usage or want backup during outages, and the federal battery scheme can help with the cost. Your installer will model your usage against solar generation and give you an honest recommendation on whether a battery stacks up for your household.
