How to Choose the Best Solar & Energy in Perth
Use this checklist before hiring any solar & energy in Perth, Western Australia.
- 1
Confirm the installer holds a Clean Energy Council (CEC) Accreditation — required to install solar systems eligible for STCs and state rebates.
- 2
Verify panels and inverter brands against the CEC's approved product list — not all imported equipment qualifies for rebates.
- 3
Get a written quote specifying panel wattage, inverter brand, system size (kW), estimated annual generation, and expected payback period.
- 4
Ask whether the quote includes council approvals, network connection application (DNSP), and metering upgrade if required — these are often extras.
- 5
Confirm the warranty terms: panels typically carry 25-year performance warranties, inverters 5–10 years, and workmanship 5–10 years.
Frequently Asked Questions — Solar & Energy in Perth
How much does solar panel installation cost in Australia?
A 6.6kW system (the most popular size) costs $5,000–$9,000 after the STC government rebate. Prices vary by state, brand, and installer. A 10kW system costs $8,000–$14,000. Always compare quotes from at least 3 Clean Energy Council (CEC) accredited installers and check what the rebate amount is for your postcode.
What size solar system do I need for my home?
Most Australian homes use 15–25kWh per day. A 6.6kW system produces 24–30kWh/day on average. For households with high daytime usage (retirees, home offices, EVs), a 10kW system maximises self-consumption. Add a battery to capture surplus energy for evening use. An energy audit helps determine the right size.
Is solar power worth it in Australia?
Yes, for most Australian homeowners. Payback periods are typically 3–6 years, with systems lasting 25–30 years. Feed-in tariffs (what your retailer pays for surplus energy exported) have dropped to 5–12 cents/kWh in most states, so maximising self-consumption is key. A north-facing roof with minimal shading gives the best returns.
What is the solar rebate in Australia?
The federal Small-scale Technology Certificate (STC) scheme provides an upfront rebate reducing system costs by $2,500–$4,500 for typical residential systems. The rebate amount depends on your location (zone), system size, and current STC market price. The rebate reduces slightly each year until 2031. State-specific rebates (VIC Solar Homes Program, etc.) provide additional savings in some states.
Should I add a battery to my solar system?
Batteries (typically $10,000–$16,000 installed for 10–13kWh) extend your energy independence and are most valuable if your retailer offers low feed-in tariffs, you have high evening usage, or you experience frequent power outages. Payback on batteries alone is currently 8–12 years. Virtual Power Plants (VPPs) can improve returns.
