What a fair Perth quote looks like
We don't sell packages or specials, so there is no Perth deal to advertise here. The low end of each band is budget panels and a budget inverter; the high end is premium brands and more complex roofs. A quote well under the low end usually leaves something out, such as a switchboard upgrade, tile work, network fees or a smaller inverter. Ask for every item in writing, with the STC rebate shown as its own line, using the solar quote checklist.
Is the solar rebate dropping in 2027?
Yes. The STC rebate is calculated from deeming years, which fall from 5 to 4 on 1 January 2027. A 6.6 kW system in Perth earns 45 certificates (about $1,784) if it is installed in 2026, and 36 certificates (about $1,427) from 1 January 2027: about $357 less at today's certificate price. The federal battery discount also steps down on 1 January 2027; see the Cheaper Home Batteries page for the schedule.
What's different about solar in Perth
Perth households on Synergy are paid for exports under the state's Distributed Energy Buyback Scheme, which pays more for exports between 3pm and 9pm than during the day. That evening window is what a home battery is for, and WA's Residential Battery Scheme adds a rebate for Synergy customers who join a virtual power plant for two years.

We match you with one installer that works your postcode, after checking its ABN and its Solar Accreditation Australia (SAA) accreditation. Our Perth directory lists the 30 solar companies registered nearby, with ABN status and years trading and no scores.
Are solar rebates dropping in 2027?
Yes. The STC rebate is based on deeming years, which fall from 5 to 4 on 1 January 2027. A 6.6 kW system in Perth earns 45 certificates if installed in 2026 and 36 from 1 January 2027, about $357 less at today's certificate price. The federal battery discount also steps down on 1 January 2027.
How long does solar installation take in Perth?
The install itself is usually one day on site. From signing the quote, expect around 4 to 6 weeks, most of it waiting for the network operator's connection approval and the installer's schedule. Ask for both dates on the quote.
What's the best feed-in tariff in Perth?
WA uses a regulated, time-of-export feed-in tariff (DEBS): 2c/kWh off-peak and 10c/kWh during the 3-9pm peak for Synergy customers, on the first 50 kWh/day. Batteries shift solar from the 2c window into the 10c window (or straight into your own evening usage at 30c+).
Is 10 kW solar enough to run a house?
In total energy, usually: a 10 kW system produces about 40 kWh on an average day (national average; Perth averages about 4.7 peak sun hours a day). Compare that with the daily usage on your power bill. The gap is timing: panels produce in the middle of the day, so without a battery you still buy power in the evening.
Do solar panels work well in Perth's climate?
Yes. Perth averages about 4.7 peak sun hours a day. Output scales with sun hours, so the same system produces less in a lower-sun city, but the STC rebate is set by your postcode's zone rating, not by what the system actually produces.
